Sukuna vs Muzan (Jujutsu Kaisen vs Demon Slayer)

“There aren't demons flying around with horns, people are demons.”

• Chuck Schuldiner

Ryomen Sukuna, Jujutsu Kaisen's King of Curses.

VS

Muzan Kibutsuji, Demon Slayer's King of Demons.

Mankind has dreamt up several monsters from the blackest of hearts over the years, be they vampires, werewolves, zombies, or ghosts. But, as we have proven time and time again, the worst kind of monster is a human, which these two immortal self-made killers have proven throughout the centuries. The strongest curse in history battles the deadliest demon in Japan for control over the dark, and the right to snuff out the light.

Before We Begin

The media list for these two is rather simple. The main sources of course being the original manga (along with Demon Slayers light novels) and anime along with guidebooks and supplementary material like creator statements.

This blog will be using both at their peak. This means we will be using the Heian Era of Sukuna (Though other forms will be covered for story) and Muzan will not be under the effects of Tamayo's poison. This means Sukuna will not be given Mahoraga and to balance this, Muzan will not be given support like Nakime and other Upper Rank Demons.

As usual, not all calculations and scans were done by us. G1’s Gojo VS Makima, G1's Rengoku VS Todo, G1's Tanjiro VS Jonathan, Round 1 Fight's Power VS Nezuko (Who is on the blog), Muzan Kibutsuji VSBW, Powers and Stats of Muzan Kibutsuji, Respect Muzan Kibutsuji, Respect Tanjiro, Respect Nezuko, Respect Inosuke, Respect Rengoku, and Respect Sukuna.

Background

Sukuna

“The thought of needing someone else to fulfill me never crossed my mind. If I want to eat, I eat. If I see an eyesore, I kill it. And if it entertains me, I throw it a bone. I love according to my own stature. If that can’t be measured or understood, that’s not my problem.”

Throughout the history of the world, there have existed two constants: curses and sorcerers. Curses born from the energy of negative emotion, and sorcerers, who sought to stop them. However, born within the Heian Era, the Golden Age of Jujutsu Sorcerers, one would rise to become the strongest in history. However, he was no mere man - from the start, Ryomen Sukuna was a monster. As a child, in order to survive, he ate his younger brother in the womb, and from here his mentality was formed - the strong would live, and the weak would die. As he grew up, he became the sorcerer known as the Disgraced One - a mass murderer, who had killed many sorcerers in his time, becoming infamous for his ruthlessness and hatred of the weak, making few allies. In the end, though, he wished to preserve his life above all else, and before he died, he had one Kenjaku turn his 20 fingers into 20 cursed objects, preserving his soul within them throughout the next thousand years, with the fingers increasing in power all those years.

While Sukuna did not incarnate throughout the years, one day, one Yuji Itadori needed to fight curses, and ate it, causing Sukuna to be able to possess his body. Laughing at his return to the modern era, he took control of Yuji’s body, before control being taken back by Yuji - however, Sukuna wouldn’t stay down forever. He soon came back, as they needed his power to defeat a special grade cursed spirit - however, he turned on them (what a shock, the mass murderer wants to mass murder people!), and in the resulting battle, Yuji died (rip bozo), causing Sukuna to propose to bring Yuji to life, but that he could possess Yuji’s body for a minute, but wouldn’t hurt his friends - the two fought in his head over the deal, and Sukuna won.  

From his victory, Yuji lost all memories he had of making the binding vow, while Sukuna lay dormant until one fateful night in Shibuya. After being put unconscious on the brink of death by Choso, he was discovered by the Disaster Curse Jogo, as he fed Yuji 10 fingers to get Sukuna in complete control for an extended time. Jogo tried to ally with the sorcerer, but failed to fulfill his end of the deal as he was burnt to a crisp, but not without one final speech of respect from Sukuna. But afterwards, Sukuna just so happened to run into your local potential man Megumi Fushiguro, and had the time of his life fighting his strongest Shikigami, Mahoraga-chan. Megumi’s technique fascinated Sukuna, as he toyed around with the Divine General before setting it ablaze, leaving a massive hole in Shibuya where thousands once resided. Sukuna then gave back control to Yuji, as the young sorcerer laid in shock at all the carnage his decision had caused. The King then lay dormant once again, as the Culling Games began.

The Strongest would not be seen again for sometime, until his surprise usage of his months old Binding Vow from Itadori while he and Megumi stared in shock after Yorozu revealed her possession of Tsumiki. After seeing his technique, Sukuna immediately restrained and possessed Megumi, wanting his Technique for himself after realizing how he could use it for himself, and killing Yorozu, and by extension his sister, to secure his possession over the boy. But he wouldn’t be done so easily, as the Jujutsu High Sorcerers would finally unseal the strongest sorcerer of the modern era: Satoru Gojo.

A month had passed now since his unsealing, all in preparation for the showdown between Gojo and Sukuna. Both had an extremely hard fought battle, eventually earning each other’s respect. However as he was on death’s door, Sukuna revealed his learning of World Slash which he used to bisect Gojo (kinda sus) and leave him the victor. But this victory wouldn’t come without consequences, as he soon fought all of the remaining Sorcerers one after another. To this day, despite the many losses on their side, they haven’t given up on putting down the King as the battle enters its final act. But no matter the outcome, history will never forget of Ryomen Sukuna: The Strongest Sorcerer the world will ever know.

Muzan

“The one thing I hate is "change". Changes in circumstances. Changes in body. Changes in emotion. In most cases, every change is "degradation". It is decline. The one thing I like is "permanence". If something doesn't change for an eternity. It's in a perfect state”

Everybody wants to live forever. That is a simple fact of reality. We all fear Death's cold embrace, and will do anything to escape it. That is the cruel and uncaring nature of human existence, and this was the same with Muzan Kibutsuji.

As a mortal in the Heian, Muzan was a wealthy man, but none of these earthly treasures could heal his lifelong sickness. Bedridden for practically his whole life, Muzan wanted nothing more than to escape these shackles, and paid dozens of doctors to do so. After his latest “special” medicine failed once more, Muzan, in his rage, walked out of bed and killed the doctor with his bare hands. Surprisingly, after this, he found his sickness was healed, and his entire being changed. He could achieve whatever he wanted in physical ability, and eat flesh to his heart's content to grow stronger. Yet, as a condition, he could not go out into the sun. Being half-locked out of his new immortality infuriated Muzan once more, so to work around this, he created others like him…Demons. 

By eating humans and cultivating his powers, Muzan crafted legions upon legions of inhuman monsters that would plague Japan across the centuries, tearing family after family and town after town asunder. With the might of these unholy monsters, and his generals, the 12 Kizuki, Muzan was unmatched. Until, that is, he met a somber swordsman with flaming red hair and a sword just as bright. This was Yoriichi, one of the first users of Total Concentration Breathing, which harnessed the power of the sun Muzan despised so much to nearly end his life. Escaping by a hair, Muzan's hatred was directed toward a new generation of “insects” that harnessed this same power, who were able to kill Demons, and potentially end his own life as well; the Demon Slayer Corps

As the centuries passed and Muzan's reach over the country grew, he became all the more infuriated at not just the ants on his boot who refused to die, but the act of their changing to attack in the first place. Muzan wished to be a perfect being exempt from change, age, or fatigue, and the Demon Slayers are a living breathing example of all that change is. His way of living without change eventually led to him eating and killing a seemingly random family in the mountains, but this would be the biggest mistake of his un-life. This family was the Kamado clan, and they were old friends of Yoriichi himself, who passed his Sun Breathing to them in the form of dance. Thus would result in the surviving Kamado's, Tanjiro and Nezuko, putting their training and Demonic nature to use in avenging their family by killing Muzan himself.

When Tanjiro by chance found him and swore to end his life, Muzan was reminded once more of his complete and utter hatred of change, of humanity itself. The very idea that something could kill him was an affront to nature itself, and so he instructed his 12 Kizuki to slaughter this pathetic child where he stood. One by one, they fell to the child of the sun, until none were left but Muzan, Tanjiro, and all of the Demon Slayers he had befriended that gave everything they had to end Muzan, and Demonkind, forever. Not a single one of these swordsmen gave an inch, and after hours upon hours of fighting, Muzan was finally killed by the sun he fought so desperately to overcome. As a last ditch effort, he possessed Tanjiro's body, and nearly had the boy kill his friends and escape in his stead, but once more humanity embodied the change he despised, and Tanjiro shook off his influence, leaving the “Demon king” screaming his name in the purse of Hell where he belonged. With his evil finally purged from the earth, humanity could rest easy, because unless he is fully and completely eradicated, there is no place on this earth that you can hide from Muzan Kibutsuji.

Abilities 

Sukuna

Cursed Energy

Cursed Energy is an energy generated by negative emotions such as grief and anger. While almost all of humanity has cursed energy, sorcerers have a higher amount of cursed energy then the non sorcerers, which lets them see cursed spirits. Sorcerers and Cursed Spirits can use the cursed energy to enhance their body, walk on water, and do cursed techniques. It’s this manipulation of Cursed Energy that is "the foundation for all Jujutsu." 

It is the concept of controlling the flow/rotation of Cursed Energy in the body, with the three core aspects of CE reinforcement being Output (出力), Quantity (総量), and Manipulation (操作). In addition to rotation and energy, sorcerers must learn the skill of proper CE flow control. Cursed Energy originates in the stomach as shown above, and novice sorcerers can consciously flow it through different parts of their body. By viewing the body holistically as one whole instead of “disparate parts”, one can advance their CE control.

With sufficient control over Cursed Energy, sorcerers can “disengage” or dispel their Cursed Energy, eject damaging Cursed Energy sent into them by their foes, and delay the impact of their Cursed Energy on a target. CE flow is generally difficult to read as a sorcerer wraps their entire body in it and then distribute it unpredictably (more so if they lack in Cursed Energy), holding back their full strength until the moment of impact as opposed to preemptively coating it. Experienced sorcerers can even attack without projecting which body part they will use to attack, and can use CE to fake a strike, the location of a cursed object on their person, or a concentration of CE / their soul.

Injuries done by Cursed Techniques become automatically cursed which has severe consequences on non-sorcerers, such as weakening and becoming ill. Cursed Energy can also be used to attack Curses, which are manifestations of images, information, and emotions from collective human consciousness' reactions to various phenomena, which otherwise are invulnerable to damage that isn't from a Cursed Energy user or using CE infused equipment. Simply being around Cursed Energy can erode the mind, and both the power of negative emotions such as fear and worship from belief can empower Cursed Energy users. Though conversely too much negative emotion can disrupt proper CE flow.

Compared to literally everyone else in the series (besides Hakari after a Jackpot), Sukuna has the highest amount of cursed energy in the series, being at minimum twice as large as the reserves of Yuta, who has more cursed energy then Gojo. He’s also noted for being one of, if not the most efficient Cursed Energy user besides Gojo and his Six Eyes. So much so that even after beating Gojo, being hit with Jacob’s Ladder, stabbed through the heart with a soul splitter, taking over a dozen Black Flashes from Yuji, taking numerous smaller hits from other characters, and dropping a Domain Expansion, his Cursed Energy levels had “only” been diminished to the level of Yuta Okkotsu’s by the time of their rematch. This has allowed him to keep fighting through ridiculous levels of damage and using cursed techniques and his Domain without exhaustion.

Sky Bounce

Sukuna, like Maki, can view and grasp the “surfaces” of the atmosphere itself and use them to step on air. Sukuna can engage in aerial combat in this manner or dodge attacks while in mid air. 

Black Flash

When Cursed Energy is applied to a physical attack in a 0.000001 second timeframe, a Jujutsu Sorcerer can land a devastatingly powerful blow that distorts space and increases their overall capabilities with Cursed Energy, allowing CE control to become as seamless as breathing and operate at 120% of their maximum potential. As demonstrated with Gojo and Mahito, landing a Black Flash can restore one's Reverse Cursed Technique output and even restore Cursed Technique usage. While it’s noted to be a technique that no sorcerer can consciously use, it’s considered not necessarily special in Jujutsu society to land one. The heightened reactions gained after landing a Black Flash appears to even help land several more consecutively as shown with Yuji Itadori.

Additionally, as explained by Gojo Satoru, the microsecond time frame isn't the only limit, citing the movement and specific blend of Cursed Energy, the air temperature, and humidity as factors in landing a Black Flash. Hence while the incredibly short timeframe should be no issue for someone on the level of Gojo, all the additional factors together make landing a Black Flash luck-dependent. Repeated Black Flashes can even restore the ability to use Domain Expansion if the part of the brain responsible for it is damaged. Sukuna used a total of four of these to re-route his brain to restore his Domain. 

Sukuna first demonstrated his ability to use Black Flash in his fight with Maki Zenin, knocking her out for a time. He would use it again to dispose of the sorcerer Larue as he was being attacked by several people at once and his third on Maki Zenin. Damn she can’t catch a break. 

Binding Vows

‘... My favorite.’

Binding Vows are restrictions/rules that cursed users can make on themselves or opponents. For example, Cursed Users can reveal the specifics of their technique in return for a massive increase in cursed energy. If the vow is broken, then there are massive consequences.

Sukuna has made multiple Binding Vows during his time in JJK (most of which during the Shinjuku Showdown arc), first known being the vow on Yuji that lets him possess him if he says Enchain. Yuji was also forced to forget about the pact’s existence. Next would be his Binding Vow to cast his World Slash technique that killed Gojo. As he only had one uninjured arm, he couldn't perform the hand sign to launch the technique. And thus to kill Gojo, he performed a vow imposed on all further activations, requiring the trajectory of the technique to be specified with his palm on top of the Enmaten hand sign. 

Sukuna can increase the potency of his Domain Expansion by changing the area of effect of his Domain with a Binding Vow. He would then make a few unknown vows to help unleash his Domain Expansion due to his diminishing Cursed Energy output. And lastly (for now), it has been revealed Sukuna makes a vow to limit the number of targets of his Divine Flame outside his Domain to increase the flames’ speed and range when DE is active (more on that later).

Shrine

While the full details of Sukuna’s exact Cursed Technique’s are still unknown at the time of writing we do know it’s referred to as “Shrine” and his most frequent application of it is through invisible slashes and slices that can cut through practically everything. From buildings to humans to Curses and even souls, as shown with his battles with the Finger Bearer, Mahoraga, and Mahito. The sheer power of Sukuna’s curse technique can turn the powerful Shikigami Mahoraga into a pile of blood.

Cleave and Dismantle are the two main variations of this technique, with Cleave being used on targets with Cursed Energy, adjusting itself based on the target’s toughness, and Dismantle being used on targets without it, typically inanimate objects. They can also be differentiated through activation of the technique, with Dismantle being Sukuna's projectile form of slashes while Cleave can only be activated upon touch. Sukuna can even unleash a massive “net” of Dismantle slashes. It’s also worth pointing out Sukuna’s incredible control over the technique, being able to spam massive, city-block spanning slashes while also being precise enough to focus the technique around his hand to “hold” and block oncoming attacks from bladed weapons. Sukuna can also use Dismantle without having to use motion, as shown against Kusakabe. 

Cleave: Spider Web

An extension of Cleave that can be used to slash apart a target in the shape of a spider web. Sukuna used this to knock Yuji and Maki off balance by destroying the ground beneath them.

World Slash

In his duel with Gojo Satoru, Sukuna managed to overcome the sorcerer and claim victory by expanding the target of Dismantle to "the world" and existence itself, bypassing barriers such as Limitless and landing a fatal blow. It does not matter how durable the target is, the victim will be split apart just as the space the Dismantle hits is split. Not even the power nullifying properties of Domain Amplification can stop the World Slash. While he gained this ability through the adaptation of Mahoraga, it’s been shown that Sukuna has retained it and can fire off a massive version of it. Its only downside appears to be that Sukuna requires time to perform the correct hand sign and chants, though he can perform a Binding Vow to launch it without any of those requirements. Sukuna has also used external sound to hide his enchantments for a surprise attack with the World Slash.

Divine Flame

Sukuna is able to manipulate flames to construct an arrow of great power, which he can release after he’s used both Cleave and Dismantle and then chanting Open. Due to a Binding Vow, he can’t use it on multiple people outside of his domain, but in return, Divine Flame can “detonate” any pulverized matter (created via Malevolent Shrine) it touches, turning dust particles into thermobaric explosives, as well as instantly compressing and decompressing shockwaves generated by the explosion. The sheer power of the explosion is strong enough to kill Mahoraga in one shot and killed the fire resistant Curse Jogo.

Domain Amplification

An anti-domain technique that covers the user in their own Domain to neutralize/mitigate other Domain Expansions and Cursed Techniques. The main drawback to the technique is the user cannot use their ability and Amplification at the same time. Due to Sukuna’s insane mastery of Cursed Energy, he can seamlessly switch between Cursed Technique and Domain Amplification. He used this technique to be able to bypass barriers like Gojo Satoru’s Infinity and harm him. Sukuna can also use Domain Amplification and Domain Expansion at the same time, which allowed him to remain in physical combat with Satoru as to negate Unlimited Void's sure-hit effect in their Domain clash and buy the time needed for Malevolent Shrine to destroy Unlimited Void. Amplification does have a limit, as it cannot fully negate Gojo’s Red.

Hollow Wicker Basket

An anti-domain technique acting as the predecessor to Simple Domain. Hollow Wicker Basket counteracts the effects of a Domain and its sure-hit effects, though cannot counteract Curse Techniques themselves. Sukuna demonstrated this technique against Yuta Okkotsu to counter his Domain Expansion, but he notes that he's unable to perform his world-cutting slash while he keeps up Hollow Wicker Basket.

Reverse Cursed Technique

Reverse Cursed Technique is taking the typical “negative” Cursed Energy and transforming it into “positive” energy by doubling and multiplying two sources of Cursed Energy (i.e. two negatives create a positive). This transforms Cursed Energy from a source that destroys into one that creates, which most sorcerers and curses use to heal wounds. RCT uses a large amount of Curse Energy and in the process creates new flesh and blood for the user from said energy. It is possible for one’s RCT output to diminish if they take too much damage.

Sukuna has demonstrated a very potent healing factor via Reverse Cursed Technique, being able to casually restore limbs and he doesn't even need a heart to continue fighting. Sukuna can also heal his heart if it's crushed or removed. This level of regeneration seems similar to that of other Curses in the series, with powerful Curses like Jogo being able to rapidly regrow limbs mid-battle.. Even while weakened Sukuna can instantly regenerate from being burned alive by Jacob’s Ladder (including a second time where two of his arms were cut off). And due to Sukuna’s knowledge on the outline of his own soul his RCT can actually heal damage done to it, granted he's in ideal physical condition.

Sukuna also learned how to use Reverse Cursed Technique to repair burnt-out Cursed Techniques by destroying and repairing his brain. This process has a limit of 5 uses before the body reaches its limit. Sukuna can also use RCT to heal others. RCT can also be used offensively against Curses, as shown by Yuta. Masters of RCT can also identify toxins and counter them, which normally is difficult to do for novices.

Finger Possession

But the true heart of Sukuna’s immortality isn’t his Reverse Cursed Technique, but stems from his fingers. The original ones he preserved and are stated to be indestructible within the world of Jujutsu Kaisen. Even a millennia past his death, his essence stored within the fingers were enough for him to restore his soul after it entered a vessel like Yuji. Even after his body sustains fatal wounds, as long as his finger is still within the host he can resurrect himself via Reverse Cursed Technique, granted not too much time has passed after death. This is all due to the fact that Sukuna's very soul is a Cursed Object which he himself can manipulate.

And even after being incarnated, Sukuna can still hop from vessel to vessel by taking one of his old fingers and forcing someone else to swallow it and take in all his Cursed Energy. From there he takes over his new vessel’s body and buries its soul. We’re shown that after Sukuna takes over Megumi’s body that Megumi's soul is essentially comatose. An interesting benefit of this is that Sukuna can transfer the burden of soul and mind-based attacks to the host's soul.

And while it won’t factor here due to the specifics of this battle, it’s worth pointing out that once Sukuna incarnates into his original body, he is healed of almost all injuries throughout his body, the only exception being brain damage caused by Unlimited Void.

Body Control

Sukuna has full control over his anatomy and can reshape the body of his host at will. Sukuna can grow eyes or mouths on different parts of his host or stretch out his head to consume his opponent. His original body also features four arms and a second mouth on his chest which he utilizes to perform incantations and hand signs.

Innate Domain

Within the world of Jujutsu Kaisen, every living being appears to be born with an internal mind or soulscape known as an Innate Domain, said to be the foundation of one’s innate Cursed Technique. Sukuna’s Innate Domain reflects that of a twisted Buddhist shrine standing upon numerous skulls within the body of some massive being (or it just represents being inside of Sukuna himself). From within this Innate Domain, Sukuna can retaliate against intruders or anyone attempting to "touch" his soul and attack with his Cursed Technique.

Malevolent Shrine

A Domain is one’s inner “territory”. By manifesting a Domain through large amounts of Cursed Energy, a Domain Expansion, one creates an area where all techniques, without exception, will be neutralized and its technique will always hit its target no matter what (that is to say the Sure Hit of the Domain will bypass techniques to hit that target. Domains do not actually nullify an ability used by an opponent.). Sukuna’s Domain Expansion takes the form of a Buddhist Shrine surrounded by skulls. A Domain represents the Innate Domain of an individual and are the foundations of a Cursed Technique, and when entering or interacting with Sukuna’s soul one can see that they've entered the same Shrine. 

Normally Domain Expansions expand the Domain outward and form a barrier between the inner world of the Domain and the rest of the world outside of it, but Malevolent Shrine expands onto the world itself without closing its barrier, hitting everything within it indiscriminately with Cleave and Dismantle. The lack of a barrier forms a Binding Vow due to allowing an escape route from the domain that enables Sukuna to expand the effective range of the guaranteed hit up to a maximum radius of nearly 200 meters, though this can be adjusted if Sukuna wants to avoid hitting certain targets. Additionally, reduction of the area just makes Malevolent Shrine stronger and extends its usage. Note that he can close the barrier if he wants to.

Upon activation a Domain will activate its guarantee-hit ability, which in Malevolent Shrine’s case is a relentless application of Cleave and Dismantle for the entire area of the Domain. This continues until nothing is left of his targets and all are reduced to dust. And on top of all that, pulling off a Domain increases all your attributes while within it akin to a stat buff in video games. Normally Domains can be destroyed by breaking their barrier. Sukuna is unaffected by this limitation due to the open nature of his Domain. Destroying the shrine the Domain summons won't stop the technique either, as the shrine is merely symbolic. Sufficient damage to Sukuna’s body will collapse his Domain. Due to his absurd Curse Energy reserves and distribution skill Sukuna can Domain Expansion multiple times in a day. 

In his battle with Gojo Satoru, Gojo's Unlimited Void and Sukuna's Malevolent Shrine were evenly matched in a clash of Domains, but since Malevolent Shrine's range was greater, it could break Unlimited Void's barrier from the outside and thus "win" the clash, harming Gojo and later forcing him to adjust the parameters of his Domain to counteract Malevolent Shrine. Sukuna can adjust his own Domain if his brain is damaged. Sukuna was able to restore his lost Domain (from the fight with Gojo), albeit in an incomplete state where it would only last 99 seconds. Furthermore by shrinking the range of his incomplete Domain, Sukuna can remove its time limit.

Muzan

Demon Physiology

As the progenitor of all Demons, any attribute they hold can be attributable to Muzan himself, and excelled far beyond given how much stronger he is.

• Body Discernment - According to Muzan, Demons can differentiate blood type, sickness, and genes in humans and presumably other creatures.

• Immortality - The high ranking demon Daki states that demons do not age. Demons also can and function even when limbs are separated. One of the first Demons ever shown (who was incredibly low level) was able to survive and function even after his head had been taken off. In terms of pure aging, other demon's have lived for several hundred years, and Muzan is over 1,000 years old; even being aged 9,000 years in a short timeframe with not that many lingering downsides.

• Unlimited Stamina: Demons such as Akaza do not know the concept of fatigue which Muzan would greatly upscale (funny joke). Muzan can deal with rapid aging (worth 9000 years) before showing any sort of fatigue, only doing so due to numerous poisons in his body.

• Body Control - As shown by the low level demon from earlier, Demons can move limbs that have been separated from the main body including the head. Muzan could even separate himself into 1800 pieces and pull these small pieces of himself together so he could regenerate. Muzan can reshape his body at will. He can shrink or increase his size, grow mouths all over his body or reshape his form into that of a young girl or boy. Muzan also grow massive flesh arms to consume his target.

• Extrasensory Perception - Most top tier characters in Demon Slayer can sense things based on their aura. Muzan could sense that humans were scattered across a mountain, and 2 Upper Moon demons had felt that Akaza had died due to a lack of his demonic presence. On the side of the humans, Rengoku could quickly figure out Akaza was a high ranked demon based on his aura, and Muichiro could feel Nezuko's demonic presence while she was in her box. Muzan could also sense Kanao, Zenitsu, and Inosuke while they were using tags to be invisible by sensing disturbances in the air.

• Aura - All characters in Demon Slayer give off an aura which can be used to analyze a character's species and power. Some demons' auras have been shown to cause the air to feel heavier, a loss of will, and even damage being internal or external.

And as the scan at the top shows, Muzan himself has his own physiology that other Demons don't such as his 5 brains and 7 hearts that he can continuously shift around within his body to avoid them being targeted.

Regeneration

Thanks to being a super-predator with humanity as their meal, a Demon has incredibly sped up healing that can bring them back from just about anything at a rapid rate so long as they have not been cut by a Nichirin blade. Muzan is no different. In his own examples Muzan has regenerated so fast some of the Hashira’s couldn't tell if they cut him, survived and regened from large explosions (shown above) even after being impaled by spikes meant to slow said regeneration and even came back from being nothing but a pile of flesh the size of a human head of which he could regenerate his full body from the smallest piece. This scan is referring to when 300 pieces came together as a head size lump. He has been cut in half by Shinazugawa, had his head crushed by Gyomei, and even been cut by the Bright Red blade, all of which he can heal from quickly.

Of note, as the strongest Demon, he should more than compare to the following feats from his vastly inferior servants and killers. This is even stated in the guidebooks. The only thing Muzan cannot regenerate from properly is the cellular damage caused to him by Yoriichi.

Other Demon Regeneration Feats

• Beheading/Decapitation - Multiple Demon's across the series can endure being decapitated, or having their head destroyed, unless it's from a Nichirin Blade of course. From low level Demon's enduring despite both these occurrences, to higher levels that can heal their mostly destroyed heads in moments, or put their own lopped off head back on to the highest who can grow theirs back, Nichirin Blade or otherwise, like Muzan.

• Dismemberment - Demon explanations have stated Demons can reattach severed flesh and grow new limbs, and this is fact for all Demons. Several demons exempt from the Upper Ranks have grown back their hands, arms, or other body parts no problem. Demons in the Upper Ranks have these same sorts of feats and statements, but on much faster and higher scales.

• Internal Bleeding - A lower level Demon is confident he can heal from Nezuko potentially rupturing his organs, and Akaza said a Demon could heal from internal bleeding in the blink of an eye.

• Severe Impalement/Concussive Force - Both Lady Tamayo and Yushiro could regenerate from and ignore getting holes blasted in the sides of their head/body by Temari's balls, and Genya could do something similar with several small holes blasted into his body.

• Organ Removal/Destruction - Across the series, several demons and experts on their abilities have stated that Demons can regenerate from this sort of thing. Shinobu, for example, has said that gouging out the eyes, slicing open the stomach, and pulling out the guts wouldn't kill a Demon or leave lingering effects. Akaza has said a Demon can easily regenerate from their eye getting crushed in the blink of an eye, and Douma considered gouging out one of his eyeballs as payment for something with no real lingering effect.

• Bisection - Akaza's body when chopped in half diagonally rapidly reconnected and regenerated, Genya could survive this as a Demon, and reattach through consuming part of Upper Rank 1's body. He did die eventually, but this was due to his only temporary usages of Upper Rank regeneration, which Himejima semi-confirmed.

• Mass Mutilation - In the case of Nezuko, pretty much her entire body was chopped up when battling Daki, yet her limbs were still connected and reattached using her blood; being sentient the whole time and still capable of battle until fully regenerating

Demonic Blood

Muzan's blood is not like regular blood. His blood is how he asserts his will and dominance of the human and demonic worlds. Muzan's blood can turn people into Demons. It's also been shown as a ranged attack. However, his blood’s main properties allow him to read the thoughts and location of any Demon he wishes. Since it is his blood and cells, he also can turn off a Demon's ability to regenerate. Another ability of Muzan's blood is that when given higher doses, it can completely melt a person's cells leaving them as nothing but dust at a cellular level. Being soaked in the blood also has this same effect (this method can take up to 5 minutes to work). Muzan's blood transfusions can also import his strength, memories and consciousness into a target. This allows Muzan to possess and control the person's actions.

Curse

Muzan is capable of placing curses onto Demons such as the one used on Sasumaru, which killed her for saying Muzan's name. However it can be escaped from through overwhelming power. 

Absorption

Muzan can absorb the cells of people and demons alike. This allows him to gain the memory's and powers. This can also be done through other demons. He can also do this through his demons to absorb others. His absorption works on a cellular level. Other demons like Douma have shown it is possible to quickly absorb an entire human body.

Cocoon

An extension of Absorption. Muzan can create a large flesh cocoon in order to heal and break down toxic substances in his body.

Body Control

Muzan has incredible control over his own flesh. He can move his 7 hearts and 5 brains during combat, make weapons from his body such as these whips, split his body in a large explosion, shape his head to be bigger and open it vertically, open his torso with a body mouth, create flesh puppets after taking the place of rich folk and can use flesh to make sunlight blocking armor.

Black Blood Brambles

One of Muzan's techniques is his Black Blood Brambles. These are spiked chains created from his blood used to damage his foes.

Mouth Suction

The multiple Mouths all over Muzan’s body can produce a powerful suction effect to draw an opponent closer to Muzan. At point blank rage this can nearly kill a person.

Shockwave

Muzan can fire a shockwave capable of causing massive damage and even paralyzing those hit by it. The Demon Art affects the nervous system, throwing several body functions like breathing in disarray. This shockwave is incredibly powerful and can be felt from a large distance away but it does have a cooldown after use that weakens Muzan. The cooldown itself though is due to Muzan having been poisoned at the time. In his prime Muzan can spam the technique and is noted that he uses his mouth suction to bring a target in a range to hit them with the shockwave. The shockwave is potent enough to send the Hashira flying and rip off Tanjiro’s arm. Normally Muzan opens a large mouth on his chest to use the shockwave, but he can also do so by screaming as shown when was in control of Tanjiro.

Energy Ball

While possessing Tanjiro, Muzan revealed he had the ability to fire a large ball of energy from his mouth. It's powerful and causes large amounts of damage but it does require a notable charge up.

Arsenal

Sukuna

Kamutoke

A cursed tool once wielded by Sukuna, a ritual weapon known as a tokkosho. Originally a pair with his other weapon, Hiten, he has since lost both weapons in the millennia between the Heian and modern era. However after his battle with the incarnated sorcerer Yorozu, she spent her final moments to establish a Binding Vow to reconstruct Kamutoke with her innate technique. It was then delivered to Sukuna by Uraume in his battle with Kashimo and would go on to use it to kill Mei Mei’s crows.

Kamutoke has a rather simple ability: the ability to summon torrents of lightning from the sky. Despite its simplicity, Sukuna appears to enjoy using it and expressed nostalgia when he used it in battle once again.

Hiten

Another cursed tool wielded by Sukuna. Nothing is known about it other than it being a trident as depicted above that he hasn’t used since the Heian Era.

Forms

Sukuna

Yuji’s Body

After Yuji Itadori would swallow one of his Sukuna's fingers to save he and Fushiguro’s life he would become the vessel to his secret uncle and the King of Curses. This form resembles Yuji but with black markings. In this body Sukuna's soul lives inside Yuji causing both to be in constant conflict. Sukuna is able to take control of this body when Yuji allows or Sukana forces his way through Yuji when he is undergoing intense emotion or pain.

Megumi’s Body

After being forced out of Yuji's body, Sukana would take over Megumi’s body where he would take full control. This body would begin to exhibit even more features of his true form as he came closer to perfection. Sukana can even use the Zenin Clan’s 10 Shadows Technique. This allows Sukuna to summon  Merged Beast Agito, a fusion of all the ten shadows. He was also able to summon the Eight-Handled Sword Divergent Sila Divine General Mahoraga also known as BIG RAGA THE OP STOPA! With this form he was able to fight and beat Gojo, who at the time was considered the strongest sorcerer in the world. 

Heian Era Sukuna

His true form and the one we are using for this debate is a form of fear. That of a nightmare from which power comes from. A being of sheer evil. This strongest form Sukuna has and has been dogging the entire cast of JJK. This form truly makes Sukana seem like a god. Growing two extra arms and a set of extra eyes he is a horrifying monster.

Muzan

Combat Form

This is the form Muzan takes during combat. It has whips on his back, arms and thighs to attack from all angles. The form also has mouths across the body with powerful suction capabilities and the ability to eat people which will recover stamina. Muzan’s thigh blades are far faster than his back and arm blades and can blitz all the hashira in a single attack. Muzan can regenerate any of the blades if they are destroyed. He can also use this to attack from underground. This form was strong enough to nearly kill all the Hashira and Tanjiro.

Tanjiro's Body

Similar to how Sukuna is having Yuji and Megumi’s bodies brought up for story, Tanjiro's body is here for that same reason as Muzan took over his body in an attempt to preserve his life. Tanjiro as a demon gained immunity to the sun and had all of Muzan’s powers. The takeover was short lived, as both Nezuko and Kanao were able to help Tanjiro revert back to a human.

Armor Form

To block the approaching daylight during a battle Muzan went on his Tetsuo arc and used flesh to create a form capable of blocking sunlight.

• Poison Manipulation: Sukuna is stated to be immune to all poisons and toxins.

• Possession & Soul Manipulation: Most attempts at interacting with the soul of Sukuna's host will lead to Sukuna retaliating from his inner domain and attacking the opponent's soul.

• Limited Mind Manipulation, Perception Manipulation, and Paralysis Inducement: Cursed Energy can erode the mind. Was able to survive 10 seconds of Unlimited Void, which can completely immobilize humans and curses due to the sheer amount of information in their heads. Sukuna can transfer the burden of soul and mind-based attacks to his host's soul.

• Foreign Intrusions: The body being a living domain means foreign intrusions cannot enter the body. They must be entered through piercing the skin or breathed inside like toxins.

Muzan

Feats

• Labeled as “The King of Demons”

• Created many, many demons to plague the world

• Killed tons of humans over his 1000s of years

• Slaughtered the Lower Moons

• Thigh Blades are faster than all the Hashira

• Faster than the other Upper Moons

Resistances

• Extreme Heat: Muzan has been set on fire and had little reaction. Furthermore he has walked off slashes from Bright Red Blades, which are extremely hot and cause burning pain. A single impalement from on these blades disintegrated a part of Kokushibo’s body, yet did nothing of the sort to Muzan.

• Poison Manipulation: Muzan should be far superior to Gyutaro, who shrugged off Poison with Wisteria Extract in it that could take down a man for a day in a mere second. Muzan is also far superior to Doma, who can quickly adapt to Shinobu's poison, break it down, and survive a dosage of it worth 700 times the normal amount needed to kill a demon. 

• Disease Manipulation: Demons do not get sick.

• Limited Regeneration Nullification: Muzan can heal, albeit more slowly, from Bright Red Blades. These blades impair the regeneration of a Demon.

Scaling

Sukuna

Various Jujutsu Sorcerers

It is no surprise for Sukuna to be stronger than virtually every Sorcerer Jujutsu Society has seen. Even at the beginning of the series, Sukuna one-shotted Yuji and has only grown far stronger as his hosts consumed more fingers. By the time he just took over Megumi’s body, he was able to hold off Yuji and Maki in the Culling Games with only 10% of his Cursed Energy output. This culminates in Shinjuku Showdown, where Sukuna was able to hold off all of the Anti-Sukuna squad one after the other, despite numerous hindrances he faced such as just finishing his fight with Gojo, taking a Jacob’s Ladder from Yuta, and being stabbed through the heart by Maki. It’s no wonder he’s known as the strongest Sorcerer in history after all.

• Yuji can crater concrete with a single hit

• Mechamaru could use Ultimate Cannon, which Panda could survive (12.2 Tons of TNT)

• Toge Inumaki left a crater with Plummet (100.4 Tons of TNT)

• Maki grabbed a bullet right in front of her face (Mach 16.3 - 21.3)

• Black Flash, a move which activates within a microsecond, has been performed by many characters like Yuji and Todo (Mach 284 - 932.9)

• Hakari moves in tandem and dodges lightning (Mach 11)

The Disaster Curses

Starting off with the obvious, Sukuna humiliated Jogo in their battle, dodging every single one of his attacks with Jogo’s only reason living being Sukuna testing him, even admitting that he would’ve survived Jogo’s Maximum Meteor. He’s also comparable to many characters who’ve fought the other Disaster Curses (such as Shinjuku Maki, who’s equal to Toji who obliterated Dagon), and is comparable to Kenjaku who’s above all of them.

• Guns and tanks are seen as useless against special grades

• Hanami could erect multiple trees (3 Kilotons of TNT)

• Mahito makes a hole (58.4 tons of TNT)

• Jogo has:

• Created a huge wave of lava (44.9 Kilotons of TNT)

• Made L A  M E T E O R (240 Kilotons of TNT)

• Said Meteor is stated to be able to turn a whole town to ash (155.29 - 832.1 kilotons of TNT to 79.5 Megatons of TNT)

• Been the goat

• Funny Volcano…

Kenjaku

(Credit to LilGalil)

Mr Mastermind himself that Sukuna has a pretty easy time scaling to. Kenjaku himself stated that he’d be unable to defeat Gojo, and Sukuna later fought and defeated him. He also contested with and defeated Yuta, who himself one shot Kenjaku.

• Dodged sniper bullets

• Left a massive crater from Uzumaki (276.8 Tons - 3.9 Kilotons of TNT)

• Took the initial pull from Yuki’s Black Hole (676.2 Megatons of TNT)

• Kenjaku had to use the Anti Gravity System to counteract it, however he only used this after the Black Hole was initially created. The calculation above uses that starting effect.

• Effortlessly weaved away from Choso’s piercing blood shots (Mach 7)

Yorozu

The head of the Sukuna fan club reincarnated many years later. Sukuna fought and defeated Yorozu while keeping up with her in combat, all while only using Megumi’s Ten Shadows he just obtained, making his comparison clear cut. She also has inferior Cursed Energy Output than both Sukuna and Ryu (who Sukuna defeated with ease).

• Created a bug like armor out of liquid metal (892 Megatons - 10.62 Gigatons of TNT)

• Created spikes out of liquid metal (10 - 119.07 Gigatons of TNT)

• Created a perfect sphere out of liquid metal (107.566 Gigatons - 1.28 Teratons of TNT) (Debatable, see Before the Verdicts)

Satoru Gojo

(Credit to Death Battle… duh)

The strongest, HIM, whatever you want to call the man. While he had to grow to near full power, Sukuna at 19 fingers was able to directly contest with Gojo in their final battle. From clashing domains, to taking attacks from him such as Red and even Hollow Purple, to putting him on death’s door multiple times and eventually killing him, there’s no question that Sukuna scales to the modern era’s strongest.

• Stated to be able to kill everyone in Japan with ease, and Special Grade Sorcerers are stated to be able to bring down the militaries of countries by themselves

• As a teenager, Gojo stated he could destroy a mountain, wiping it off the map (1:27) 

• To support this feat, Geto fought the Cursed Spirit and mentioned how his Rainbow Dragon could deflect its attacks. The Cursed Spirit in question could span a whole mountain with its routes and shook it when it was born.

• While this is from secondary canon, with this game showing Hanami’s domain, it is to an extent canon and has yet to contradict it, and as such we deem it fine to use.

• With Hollow Purple:

• Tore through a huge part of a forest (66.55 Tons - 7.98 Kilotons of TNT)

• Blew up a massive amount of buildings in Shinjuku

• From just being unsealed from the Prison Realm, caused an earthquake (515.2 Kilotons - 12.94 Megatons of TNT)

• Stated to be capable of powering an entire nation with his Cursed Energy (22.2 - 94 Megatons of TNT, likely much higher)

• Outpaced multiple attacks from Jogo’s bug bombs (Mach 47.32 - 93.89)

• In a minute, processed the last three years of his life (Mach 240.92)

• Can react within microsecond intervals (Mach 888.6 - 2915.5)

Muzan

Tanjiro’s Group

The core of Demon Slayer is a powerful group. In their quest to rid the world of Demons and save Nezuko they became quite powerful. Yet they still pale in comparison to Muzan as it took a lot of the Demon Slayer Corp. (Including Tanjiro’s Group) to successfully beat Muzan, who was slapping them around like dolls (here's an example). While this group is strong, none of them alone compare to Muzan's power.

• Tanjiro has…

• Decapitated Enmu as the Demon Train

• Stabbed Akaza who is an Upper Rank 3 Demon

• Dodged Kiyogai's drum attacks (Mach 0.27)

• Zenitsu has…

• Blitzed Kaigaku, whose Blood Demon Art acts as lightning (Mach 362.47) 

• Zenitsu himself has been stated to be as fast as lightning in databooks, before getting much stronger later on

• Inosuke has…

• Punches someone hard enough to crack a wall

• Headbutts a train car to knock if off someone

• Breaks through a floor

• Survived getting slashed away by Doma

• Nezuko has…

• Decapitated a demon with a kick

• She also decapitated Upper Rank 6/Daki

• Catered the ground by stomping

• Pushed Tanjiro out of the way of “lightning strikes” (Debatable, see Before The Verdict)

Various Hashira

The Hashira’s are the pinnacle of Demon slaying. Using Nichirin Blades and powerful breathing techniques it's hard for weak Demons to keep up. However, Muzan is not a weak Demon. He has taken on multiple Hashira at once and Demons weaker than him like his Upper Moons have beat Hashira. This shows that Muzan should easily upscale the feats of even the strongest Demon Slayers.

• Rengoku causes an explosion with Akaza

• Muichiro cut 10000 killer fish in an instant (Mach 526.02) (See Before the Verdicts)

• He was able to cut all these fish before he hit the ground. (Mach 0.88)

• Mitsuri jumped over lightning and moved so fast it barely moved (Mach 317.47-1,420.32 for the jump) (Debatable, see Before the Verdict)

• Tanjiro believed a fight between Giyu Tomioka and Shinazugawa would threaten multiple buildings, people, and potentially a town in a Light Novel

Upper Moons

As the king of Demon's Muzan easily upscales even his most powerful set of Demons, the Upper Moons. He's consistently shown to be above them and even his aura alone can cause massive damage to Moons like Akaza. To say the least, he scales.

• Upper Rank 6/Gyutaro let loose a gigantic explosion of his Blood Demon Art upon his death that destroyed the Entertainment District (2.4 Kilotons of TNT)

• Tanjiro, Tengen, Inosuke, and Zenitsu could all survive this while near death and after poisoning themselves, meaning at their peaks, they would be significantly greater.

• Upper Rank 4/Hantengu could blast away parts of buildings and cause a crater in the ground with basic attacks

• Upper Rank 2/Doma could create a large ice sculpture (70.1 - 458.32 Tons of TNT)

• Upper Rank 3/Akaza can move within a fraction of blink

• Nakime/Biwa Demon shook the entirety of the Infinity Castle, and almost made it come apart through a mental battle with Muzan (6.3 Kilotons - 100.8 Kilotons to 8.8 Megatons of TNT (Debatable, see Before the Verdict)

Yoriichi

The originator of breathing techniques and the best of the Demon Slayer's, Yoriichi is quite the power house. However Muzan was quite the match for him. Yorichii has complemented a weaker Muzan on both his speed and ability to one shot him. While in his fight he was quite fast Muzan could at least somewhat keep up with him and has only grown faster and stronger overtime meaning it's very likely he could scale.

• Cut 1500 pieces of Muzan's body in a short timeframe (Mach 22)

• This feat could likely get much higher if you account for Muzan's body bursting however, we do not know the speed of the pieces and thus cannot have them in the equation.

• Says he could TRANSCEND THE LAWS OF NATURE-

Experience/Skill/IQ/Other

Sukuna

As the King of Curses, Ryomen Sukuna is the Strongest Sorcerer that Jujutsu Society has ever seen. Across the Golden Age of Jujutsu, many sorcerers tried to take down the King, yet were all killed by his hands. This included many powerful figures, such as the Elite Fujiwara Clan, the entire Celestial Squad and the five Void Generals and the Desshichin Squad from the Abe clan, which included Angel and the Sugawara Clan’s remnants. His reign wouldn’t end there however, as he split himself into twenty fingers to resurrect himself in the modern era.

As for combat capabilities, Sukuna is incredibly skilled. He’s demonstrated phenomenal hand to hand capabilities, matching if not surpassing many of the modern day’s best sorcerers, such as bodying Jogo whenever he threw hands and holding off Yuji and Maki simultaneously with only 10% of his Cursed Energy output. He’s even battled Satoru Gojo, the modern era’s strongest, and earned his respect after their battle. This is especially impressive considering Kenjaku, a being who’s lived for 1000 years, outright admitted he couldn’t beat him.

Sukuna’s incredible combat ability extends to his mastery of Jujutsu Sorcery. While not much is known about his growth as a sorcerer, Sukuna demonstrated incredible knowledge on everything it has to offer. He’s mastered many techniques as brought up above, even taking them to new heights previously unseen such as being able to create his Domain without a barrier and adding a Binding Vow to increase its area up to 200 meters. In a prolonged battle with Mahoraga, Sukuna demonstrated great utilization of his technique, Shrine, in tandem with his hand to hand skill to wreak havoc on the Shikigami. But perhaps most impressively, is that he’s fully optimized his own body for techniques, having two extra arms and a mouth to assist with incantations and techniques mid-fight.

Sukuna’s skill is further complemented by his incredible intellect in battle, having adapted to almost every ability he’s had to deal with. For example, Sukuna was able to deduce Mahoraga’s adaptation in a short period of time after it recognized it adjusting to Dismantle, and answered this by using Malevolent Shrine and Divine Flame to destroy Mahoraga so he had nothing to come back from. Sukuna’s also shown to quickly adapt to any new options he gains, such as demonstrating masterful use of Ten Shadows in his fights with Yorozu and Gojo despite just entering Megumi’s body. His adaptation doesn’t end at just playing around foes, as Sukuna’s even copied techniques from just seeing them once. Sukuna learned how to become a cursed object from just observing Kenjaku turn his soul into one, and applied this skill against Gojo by learning how to use Reverse Cursed Technique to recover his own technique after only seeing it used by him once. And for perhaps his most infamous example, he learnt the ability to cut the world itself after using Mahoraga as a model. 

However, this intelligence isn’t just seen in combat, as Sukuna is an incredible tactical planner as he plotted across the entire series for his eventual return. As an example, recognizing the potential (vineboom) of Megumi’s Ten Shadows technique, he waited until he was at his lowest mentally before taking over his body thanks to the previously mentioned Binding Vow with Yuji by force feeding him his finger by betting on Yuji not accounting for himself within it.

Lastly, Sukuna’s experience and skill is further shown across his fights by the end of the series. He fought in a prolonged fight with Gojo, and afterwards instantly fought several rounds of the Anti-Sukuna Squad following Gojo’s defeat and is still fighting even as of writing this, despite taking several beatings and fatal injuries.

Muzan

Muzan is the first Demon, and has existed for 1000s of years. In this time, he has become a master in combat in every sense of the word, and enhanced his demonic powers far beyond the norm. He can detect those who are invisible by hearing the air part, think on the fly to counter his sun weakness using flesh, and take on multiple Hashira at once along with practically the entire Demon Slayer Corp. 

For reference on how skilled Hashira are, Kyojuro Rengoku was a match for the Demon Akaza in raw combat, who slaughtered nearly 70 users of Kendo with his bare hands. Every single one of these warriors wields different styles of fighting, like swords, makes, and poisons, or elements to throw at him, like fire, water, lightning, wind, stone, and more. Yet despite all of these Fighters and their tools, Muzan more than held his own, and bit by bit he picked all of them off in the battle. 

Even outside fighting, Muzan is a genius chemist and schemer, who has evaded the Demon Slayers for centuries unless he wants to be found. He has matched wits with seasoned geniuses like Tanjiro, and had to be forced into the sunlight on top of several methods of chip damage to actually be killed, and doing so in of itself is all but impossible due to his skill.

Weaknesses 

Sukuna

While he may be the most menacing Sorcerer ever known, even Sukuna has his weaknesses. His pool of Cursed Energy, while gigantic, does have its limits and can leave him to be outlasted if a fight drags on for long enough. Sorcerers cannot use their innate techniques after casting their Domain Expansion, entering a burn out of sorts for a short period of time. And while he’s picked up recovering his innate technique via RCT from Gojo, it requires him to damage and heal the Right Prefrontal Cortex of the brain which has an eventual black box that can be reached should it be used 5 times. He’s also got limited use for Malevolent Shrine, as if his brain takes too much damage, such as taking ten seconds worth of Unlimited Void, it prevents him from casting his Domain until he can recover. 

As he’s incarnated into a vessel, it’s possible to separate Sukuna from his host from either purification like Jacob’s Ladder or Yuji’s ability to attack the barrier between him and Megumi’s souls. Even taking these attacks alone can eventually prove detrimental, as the separation from Yuji’s attacks slowly separated him and Megumi’s souls which decreased his Cursed Energy output. He even lost his ability to even try recovering RCT after taking seven Black Flashes from Yuji later on.

Muzan

Outside of not showing up for half the story Muzan has very few weaknesses. However, he does have some very notable ones. His main one of course being his weaknesses to sunlight as if he is touched by sunlight too long he is burnt to ash. This weakness to sunlight is also used in Nichirin Blades which can cut him. Muzan can also be affected by certain poisons (though he massively resists most) which can slow down his regeneration and age him many years in advance. He also has a major weakness in his hubris which has caused him to under estimate foes who he deems weaker which has led to him being caught off guard.

Sukuna dodging Electromagnetic Waves

During the events of chapter 237 and 238, Sukuna dodges an attack from Kashimo who was using his innate technique. This attack was an electromagnetic wave, which travels at light speed. Later on, while in his incarnated form, Sukuna reacts to and outpaces the same electromagnetic wave with his World Slash. This can yield anywhere from 5.3 - 7.4 times the speed of light based on the first dodge he does. That being said, there are a number of counter arguments for this feat, so let’s go through them.

The first argument stems from Sukuna dodging the EM Wave itself, asserting he was aim dodging as he saw the attack coming and then moved away. However this argument overlooks the fact that we can visibly see the EM wave is already coming out of his palm on the top of the page, and we can see Sukuna moving away as the wave is being fired (indicated by the dashing lines next to him). Plus, at the end of the fight we also see Sukuna cut Kashimo’s strongest attack, which is likely an EM wave. It’s harder to argue this being the same EM wave, but is meant to support Sukuna reacting to these kinds of attacks.

The next argument one might bring up is the arguments of the EM Waves having contradicting properties, that being them having force and vaporizing what they come in contact with. However, this can be easily countered by arguing Kashimo’s Cursed Energy being infused into the EM Waves giving them the vaporization properties. This doesn’t explain them having force, but it can be argued that Gege chose to depict the vaporization in this way instead.

Finally, some may bring up the anti-feat of Sukuna being hit by Kashimo’s first attack, judging by the sounds used and Sukuna commenting on the loud noise of the attack to conclude the attack being sound based. However, just because sound is present doesn’t mean it’s automatically based on sound waves, and there are many, many feats within Jujutsu Kaisen that get about the speed of sound anyhow, including characters dodging Piercing Blood which explicitly moves that fast. So it’s likely that this instance isn’t an anti-feat, rather Sukuna just being caught off guard. Funnily enough, Mitsuri actually has a similar instance in the same fight where she performs her lightning dodge feat (detailed later) where she gets hit by Upper Moon 4’s Compressed Sound Waves attack. So if you do use Sukuna being tagged by Kashimo’s so claimed soundwave attack against the EM Waves, Mitsuri’s lightning jump should be dismissed under the same standard.

Overall, despite the multiple counter arguments, there’s ways they can all be responded to, and ultimately comes down to whether you believe Kashimo’s EM Waves have enough backing for them being lightspeed.

Yorozu’s Perfect Sphere (and other Construction feats)

For the people who analyze JJK stats, one calc came to light when someone was just doing a hypothetical on Yorozu's Perfect Sphere. (Un)funny man Normally Normal had taken a look into Yorozu and her power of creation and her ability to create a perfect sphere out of liquid metal. When the calculations around the sphere were refined the it ended up as 107.566 Gigatons of TNT on a low end and a whopping 1.28 Teratons of TNT on the higher ends. So now we have to answer, are these calcs valid?

The calcs use Energy to Mass conversion due to the creation feat stemming from the Curse Technique called Construction. Construction creates mass from Cursed Energy, and causes a toll on the body of the user. Yorozu uses Construction to make liquid metal from her Curse Energy and then feeds more Curse Energy to control the metal. She can repeatedly do this despite the toll on her. She even has enough Curse Energy to use a Domain Expansion after making the Perfect Sphere. She has lower CE Output than Ryu and Sukuna, who defeated her.

There is some support for the method used in the calculations given the nature of Construction. Yorozu has several more feats (via the calced method) to support the placement for Perfect Sphere which you can find in her scaling section. There is some contention with these calcs in the stance that Domain Scaling would become viable as well. This is not the case as Domains are mostly symbolic and do not remain in the world if their barrier collapses. They are more like pocket dimensions. There is also the fact that Mai’s bullet creation is a few Kilotons of TNT if this method is used. This is likely not an issue, as Mai is incapable of creating anything more than a single bullet per day, unlike Yorozu. Whether or not Mai’s feat is an outlier is a different subject, as the goodwill event had other MCB/Town level feats.

Given that Ryu has more CE Output than Yorozu, he and other sorcerers comparable to him (like Yuta, Sukuna, Gojo) automatically scale to her creation feats. Based on all the evidence we have available we believe the feats and calcs are valid to use. Yorozu be hard carrying this verse, it seems. 

Mitsuri and Lightning

Recently lightning feats in Demon Slayer have come under scrutiny. This is due to the fact that most if not all feats involving dodging lightning do not demonstrate the blot originating from the sky (clouds). While this may be true, the narrative implication in series is that the Zenitsu and the Hashira are lightning timers:

(Source: Second Databook)

Users of Thunder Breathing are stated to be able to move like lightning. It is also stated that Zenitsu moves with the momentum of lightning. The sheer speed of Thunder breathing is compared 1 to 1 with the speed of lightning ripping through the air. This is entirely consistent with the modified Thunder Breathing Kaigaku uses (his Blood Demon Art) having the shape of lightning and some of the properties of it (which Zenitsu blitzed). There is a narrative basis for lightning timing feats to be legitimate because the Hashira are meant to be this fast. Mitsuri dodged Lightning from Upper Moon 4, and Nezuko also managed to avoid bolts as well. Mitsuri and Zenitsu’s feats are attributed to their superhuman speed.

Given the narrative support for users of Thunder breathing being Lightning Timers, as well as consistent lightning timing feats from other characters, it is safe to say the narrative supports this level of speed for the cast of Demon Slayer.

Muichiro’s Fish Cutting Feat

Many Demon Slayer blog readers may know of this feat and know of its Mach 526.02 calc. However, this calc goes off inaccurate assumptions of the feat that can be debunked by simply watching the anime. For context, the mist Hashira Muichiro Is up against Upper Rank 5/Gyokko. Gyokko has an attack which sends 10000 poisonous slime fish at his target. Muichiro is able to deflect some of the fish and even cut all of them before they can poison him. Sounds great, right? WRONG! You see the calc uses an assumption for the amount of slashes Muichiro uses to deflect and cut the fish. On a low end, this is 1000 slashes. However, in the anime version of the feat we see that Muichiro uses 16 slashes to block the first set of fish and 1 giant slash to cut all the 10000 fish in half. The fish also had been assumed to be moving at the speed of sound which was based off some earlier characters being stated to move at the speed of sound - however, this doesn’t really apply here since while he was expecting to overwhelm Muichiro, this is blatantly calc-stacking. Without these Muichiro’s slashes would grant a much lower yield than the original 1000 slashes and speed of sound fish.

Yet we can use a different methodology with a new… no… OLD CALC! We had this calc right for years. Since the old calc relied on flawed distance/timeframes/fish speed to get the speed it did. By using the time it would take for Muichiro to slash as a timeframe and the 1000 swings it would get Mach 27.76… SIKE! Remember it's not 1000 swings as clearly shown in the anime. So accounting for the… 17 swings… he's only getting… MACH 0.88. Thanks to Rina for the new calc but…

THIS GUY IS A FRAUD!!!

Infinity Castle

The biggest and most contentious feat in Demon Slayer is the of Nakime's Infinity Castle. A large structure that yields large results ranging in the low to mid kiloton ranges. Not bad, but this calc only accounts for what we see on screen. Another method to theoretically calculate its whole size has been used that reaches a whopping 8.8 Megatons of TNT. However, this method has come under scrutiny for a few reasons. So is this calculation right? Well, we will be presenting both the arguments for and against 8.8 Megaton Infinity Castle to allow you to decide its validity.

Pro-Infinity Castle

I'm assuming everybody knows me (Round 1) as the guy the Vs Community thinks and memes about the nanosecond people bring up “Infinity Castle”. So, here I am once more to set the record straight on the feats regarding the Castle, why it scales, and my general thoughts on it.

1. What is the feat?

The feat in question revolves around Muzan's servant Nakime, and her Blood Demon Art. In essence, this warps space to create and sustain this Infinity Castle; a sort of other dimension from which Muzan and the Upper Moons hide from the sun when convenient or just form their plans. Nakime's power is in essence the Infinity Castle itself, and she is the reason it exists. From a vs standpoint, you can use this in several ways, like creating it in the first place, destroying it (more details later) and the main focus, the Potential Energy. This is essentially getting the mass of an object and applying a simple moving speed to it in order to form a Kinetic Energy formula; Mass times velocity squared. Thus, for the feats overall power, one needs to find the Castle's weight, which is where people (or at least I do anyway) are split opinion wise. 

We are not shown much of the Castle in the Anime or Manga to get a distinct size for it, so different methods exist to find that. You are probably familiar with the first calculation from the Rengoku vs Todo G1 Blog, which gets 6.3 - 100.8 Kilotons of TNT. This is formulated through a shot of the Castle when Akaza is flying up above an area akin to a city's buildings, and from there you can pixel scale those structures, and the apparent length of the area. With these values, one then finds the weight of materials, assumes composition percentage, and boom; there's the calculation. I however don't exactly agree with this method for a few reasons. 

2. Differing Calculation Methods

First, this very obviously isn't the full castle even if I did only buy the calculation. Just earlier in the scene Akaza fell for extended periods of time, rose at great speeds, and moved between multiple layers to the structure that we can see (around 3 for whoever is wondering). This would multiply the calculation by extension, as everybody knows from the memes about me. Beyond that, this would also reasonably extend the width of the area as well, but that is semantics for my thoughts really. 

To get an overall length to the Castle, I turned to when the Slayers were trapped in there around the final act of the series. They were all separated and thrown to different points in the structure, like how Shinobu was dropped in the same layer as Douma's castle. It took the majority around 5 hours to find each other again, and this is the calculation I refer to and aim to fix for all intents and purposes.

In essence, the method in the calculation was simple; get an average walking distance to find how much they walked. TLDR for the logic used, an average person walks 1 kilometer in 10 minutes, meaning in 5 hours they would reach 30 kilometers. To account for issues like the Slayers changing direction (more on that later) as well as miscellaneous things like fighting demons, I cut the distance they covered down to 20 kilometers and spoke with the people behind the calculation to get the result of 8.8 megatons of TNT by having that length with the average height of a layer, that being the Akaza multi-building one. This has been controversial I'd say in circles, and let me clear up some problems regarding it.

3. What I'd change and why it matters

As some have brought up, the walking speed used in the calculation is incorrect, which would offset the overall distance covered. The actual average walking speed of an average human is 1.4 meters per second, and that translates to 5,040 meters per hour, meaning the calculation would really use the number of 25,200 meters. Assuming I cut off 10,000 meters like the last one for extenuating circumstances, that changes it to around 15 kilometers, which would lessen the value, so apologies on that front. Today I'm changing the idea to account for things the last one did not.

Starting, the previous calculation didn't account for certain things due to the time frame and my thoughts at the time. The prime example of this would be using walking speed and not running speed. The Slayers are very obviously running in context to find each other given the circumstances and their mission to kill Muzan. As stated earlier, I left that logic out for other reasons, along with the notion that the Slayers are superhuman in running speed but once more, semantics. I also could have lowered the distance they covered more for reasoning that others have, like assuming Nakime actively warped large portions of the Castle to mess with their destination, or that they didn't run straight the entire time. Both are valid arguments which I'll speak on later, but for now this leads into the new method.

In the new method, in order to account for any argument that they change direction, let's bring up the running example again. While an average human walking speed is 1.4 meters per second, their running Speed is 5 - 7.7 meters per second on average. As for time taken, I lowered the timeframe of the 5 hours they spent trying to find each other to just one. This was done to account for changes in direction, so using it, and the speed value shown above (5-7.7 m/s) means the distance covered in an hour would be 18 - 27.720 kilometers. For reference once more, the megaton calculation I refer to had a length of 20 kilometers to get the overall weight and result it did, meaning this new calculation angle would either slightly lessen or improve the feat, but overall not change much numbers wise.

4. Why I think this is logical

People have brought up that the characters likely changed direction, or that Nakime has altered their distance, making this impossible to scale. To that, I don't believe that makes much sense when you look at context. For changing direction, while that is a fair point, it wouldn't hinder the calculation here because they'd really only be going left or right or directions akin to that, not backwards and in areas they had already covered given the stressful situation. Limiting the overall time they moved forward to a singular hour as opposed to five is more than enough to account for these issues, and let's turn to Nakime's second issue people disagree with. As for her simply warping the direction of the Castle to mess with their path, and therefore, mess with the distance, we aren't given any real proof or semblance she's doing this; quite the opposite really. From the examples we see of the Slayers going through the Infinity Castle, like Tanjiro and Giyu Tomioka, her tactics mostly consist of summoning monsters to their location and altering their general area to try and separate them, like forming differences in the hallways to split them up. 

Obviously this is nowhere near the level needed to prove she's messing with their distance, and there's more proof we can add to this. Later on, when Nakime was warping the entirety of the Castle in her struggle with Muzan through Yushiro, all of the Slayers were visibly very surprised at this. Therefore, they haven't seen her do this before in the five hours they have been running around and fighting her, so it's extremely unlikely she was teleporting them or their areas around willy-nilly. The only counter left is saying she did so off-screen, to areas we don't see. On that end, I disagree with that for a few other reasons. For one thing, nothing at all implies she's doing this and we never see proof she does. To further this, if she was really doing so, then there is no logical reason the Slayers would have found each other to begin with. If Nakime really wanted to mess with portions of the Castle to in turn alter how long they were running, the most logical choice of action would be to just put them in an endless loop until they get tired or starve to death; let alone never group up and actively put more demons like herself and Muzan in danger. Whether or not you want to wave this away as P.I.S (Plot Induced Stupidity) is ultimately up to you, but I simply think it adds more credence to Nakime not shifting the Castles insides to alter their distance run in any meaningful way. 

5. How this scales

Before the final portions of this section, I'll simply address how this scales. In Demon Slayer, a Demon gains power through consuming flesh and the blood of their strongest, Muzan. This blood directly correlates to overall strength, and the Upper Ranks who are higher up have more of it. Speaking of the 12 Kizuki, it's quite obvious in story and from a vs perspective each of them are stronger than the last. For example, Tanjiro and Nezuko fought Gyutaro and Daki, who are Upper Rank 6, and won by the skin of their teeth. After a large power boost due to this experience, they could take on and eventually defeat Upper Rank 4; Hantengu. This is frequent, as training and power boosts and etc are needed to take on higher Demons in the totem pole; it's why Hashira Training was even a thing before they went after Muzan. 

So, how much of Muzan's blood a character has and their rank on the Kizuki can be used to determine their power through Scaling. In the case of Nakime, she took the place of Upper Rank 4/Hantengu after his death, so anybody who scales to him would by extension scale to her, and anybody above would simply upscale. To people who say “Nakime doesn't scale physically to the Castle!” You would be right, except it is ultimately inconsequential. Nakime manipulates the Castle for all of her purposes and feats using her Blood Demon Art, which…is the Infinity Castle. Blood Demon Arts directly use the blood and overall strength attributable to a Demon through Muzan's blood, their power source, to unleash their strongest attack. Nakime can't scale physically, but her place in the hierarchy means that others would be comparable to the Castle through being higher up and the factor of Muzan's blood allowing her to do this.

TLDR; it scales through ranks, Muzan's blood, and consistent Demon Class Mechanics

6. Final Thoughts

So that's basically it. Ultimately I think the Castle calculation method I have proposed holds weight and can be used, simply because it is as restrictive as possible in my eyes. Not to beat a dead horse and make the community laugh at me even more, but this once more is the bare minimum for how large the Infinity Castle can actually be. It does not account for separate layers in the structure we see in Akaza's flight, the Slayers potential superhuman running speed (but you don't have to use this, just an idea) and another factor. Technically speaking, if the Slayers took 5 hours (really 1 for calculations sake but semantics) trying to reach each other by going straight (however many turns you think they make shortens time spent going forward but that Is their overall goal) this would debatably increase the distance of the area. Think of it like this: if Nakime placed the Slayers all around the Castle, like at opposite ends of it for one, then that would mean both parties crossed 20 kilometers to get to each other, making the actual overall distance 40 kilometers. You could go much farther with that logic in mind, but the point is this calculation doesn't account for any of that higher logic. It chooses their logical moving speed of running, limits their overall time spent moving forward to 20 kilometers, and thus doesn't change much from the 8.8 Megaton calculation which also uses the value of 20 kilometers. Thank you for listening to my TED Talk, and apologies for any issues with the prior calculations others might have had.

Anti-Infinity Castle

So, I’m Door-kun, your local girlfail and I want to talk about why I think the megaton end of Infinity Castle is a fundamentally flawed way of calcing it that will always end up as a massive highball.

My big problem with this version of calcing the feat is that it feels very much like you have to use a lot of assumptions in order to justify the end. First of all, moving around the Castle. While yes, Nakime hasn’t been shown doing this, cutting off rooms and paths as well as unleashing monsters on the Demon Slayers still would cost valuable time for them, time which the new calc does not take into account - in addition, the speed itself would also be changed by these encounters as well as if she did move any room, which we know she can do, especially since we do not know the entirety of what she did here, nor the timeframe for how long they were split up. It requires a lot of assumptions to use the walking distance version of this calc to assume its size to begin with, especially since the castle also has multiple stories, meaning the size of it could be thrown off by the Slayers going up and down stories instead of going simply around one big story with the rooms, which would throw off the assumed size to begin with. As a result of all of this, I can’t support the megaton ends of the Castle, as they simply rely on too many assumptions compared to the wide shot version giving us a much simpler way to calc the potential energy of the Castle itself. Thanks for your time.

Verdict

(Verdicts screen by Cabbage)

Stats

Before we start with stats, it’s important to preface both Sukuna and Muzan’s positions as being the strongest characters of their respective verses. This should mean that almost every feat performed in their verse they should scale to, if not easily surpass in stats.

Let’s start off with Jujutsu Kaisen’s strongest sorcerer first. Sukuna is comparable to various Kiloton feats across the verse, such as Hanami erecting multiple trees (3 Kilotons), Kenjaku leaving a crater from Uzumaki (3.9 Kilotons), and Jogoat creating a wave of lava (44.9 Kilotons) and his infamous Maximum Meteor yielding 240 Kilotons of TNT. However, these are nowhere near the highest the verse can get for feats. Jogo’s meteor was stated to be able to turn an entire town to ash, which gets 79.5 Megatons of TNT, and Sukuna utterly bodied Jogo in their encounter and would’ve survived the meteor had it hit, and this was before his peak. At his peak of power, Sukuna fought and defeated Satoru Gojo, the modern day’s strongest. This scales Sukuna to many impressive feats, such as Gojo’s unsealing from the Prison Realm yielding at most 12.94 Megatons of TNT, or his Cursed Energy being capable of powering a whole nation, using the likelier scenario of it referring to the US, getting 94 Megatons of TNT.

However, this isn’t even the most impressive scaling that Sukuna can get. As mentioned in his section, Sukuna easily scales back to Kenjaku through Gojo and Yuta, whose initial pull from Yuki’s Black Hole would equal to him surviving a force of 676.2 Megatons of TNT! However, if you wanted, you could push the verse even higher through… Yorozu? Weirdly enough, her technique Construction in tandem with her Liquid Metal gives many incredible AP feats Sukuna easily scales to since he defeated her. This includes her creating bug-like armor (892 Megatons - 10.62 Gigatons), creating multiple spikes (10 - 119.07 Gigatons), and at best, creating her Perfect Sphere, which gets anywhere from 107.566 Gigatons to 1.28 Teratons of TNT! Suffice to say, Sukuna is packing a lot when it comes to AP and Durability, so how does Muzan stack up?

Well, starting off with the King of Demon’s low end feats, he should be easily comparable to Gyutaro’s explosion from his Blood Demon Art upon his death. This would yield 2.4 Kilotons of TNT, and characters Muzan scales to like Tanjiro and Tengen should easily upscale this feat given they were poisoned and near death while taking it. But of course, if you’re at all familiar with Demon Slayer in verses, there’s one big elephant in the room to tackle: Nakime and the Infinity Castle.

While this feat does have the 8.8 Megatons argument it does have a lot of holes that can be poked into it, with most members of this blog disagreeing with the high ends. This would lead to 6.3 - 100.8 Kilotons of TNT ends being much safer to use for the feat.

However even with the best interpretations of Infinity Castle’s size, Muzan still comes up short from the King of Curses’ in Power and Durability, as Sukuna would be far stronger just from scaling to Jogo’s Maximum Meteor statement and Gojo’s nation powering feat, let alone Kenjaku’s black hole pull and Yorozu’s various Constructions. Even accounting for upscaling for both, Muzan would never get close to the latter two feats Sukuna’s got going for him, but for the sake of argument let’s cap the verse’s feats at Gojo powering a nation and examine their upscaling.

As per the blood system in Demon Slayer, Muzan should be far above Nakime, as she only possesses a fraction of Muzan’s blood compared to Muzan being the source and all, which would make him heavily upscale her manipulating the castle. However, the same can be said for Gojo’s nation powering. While Sukuna obviously isn’t upscaling Gojo, the feat in question uses Mahito’s Cursed Energy as a comparison after he fought Mechamaru. Mahito's a very early antagonist in the series, and even when Yuji only possessed a handful of fingers Mahito was debilitated after accidentally attacking Sukuna’s soul with Idle Transfiguration after he cleaved him in response. He also utterly humiliated Jogo in their encounter at 15 fingers, constantly tearing his limbs off and one-shotting him with Fuga, and is only stronger at 19 fingers. There’s more upscaling arguments to be made for both characters, but the point is that any upscaling you can give Muzan from Nakime, Sukuna can match from his massive superiority to Mahito, whom the feat’s based on.

So Muzan’s far behind in AP, but what about speed? Well starting off with the smooth criminal, Muzan’s blitzing of Wakuraba would yield Mach 117 speeds, and scaling to early Zenitsu, who is stated to be as fast as lightning, and outright blitzed Kaigaku who’s also at lightning speeds, yielding Mach 362.47. As Muichiro’s feat is fraudulent, this would be where the verse would cap in speed normally, but that may not be the end of it. Lightning feats are highly consistent for Demon Slayer, such as Nezuko avoiding bolts and Mitsuri dodging Upper Moon 4’s lightning to where it was barely moving. These feats wouldn’t be enough by themselves to put the series at lightning timing, but given Mitsuri and Zenitsu’s feats were both from their superhuman speeds, it stands to reason that both relate to the source of lightning. Taking this into account, Mitsuri’s feat yields anywhere from Mach 317.47 to 1420.32 for her jump, of which Muzan would be far above given all the slayers needed to kill the guy.

Let’s see how Sukuna compares. Starting off, many characters in the series, including Yuji, Todo and even Sukuna himself are capable of using Black Flash, which activates within the microsecond. This yields anywhere from Mach 284 - 932.9, and considering even sorcerers like Nobara were capable of performing this move, Sukuna would be far faster then this. However recently, Gojo admitted himself he’s able to detect microsecond intervals with Six Eyes, which yields speeds from Mach 888.6 to 2915.5, of which Sukuna obviously compares to. Considering this is an early series Gojo giving this information and him training for his battle with Sukuna for a month, it’s likely that Gojo’s gotten much faster. However, after defeating HIM, Sukuna performed one more interesting feat: dodging Kashimo’s EM Waves. While there’s some contention among the blog as to the legitimacy of the wave’s speed, even with what was mentioned in Before the Verdicts, if you do accept this it would yield anywhere from 5.3 to 7.4 times the Speed of Light! This isn’t getting into how Sukuna could be even faster, as he just came off a hard fought battle with Satoru Gojo and barely surviving an Unlimited Hollow Purple nuke.

To avoid the upscaling discussion again, both sides have detailed that they should generally be a great deal above their feat, albeit both are difficult to quantify and thus won’t be the crux of either potentially being above the other in speed. Muzan could be argued to match Sukuna’s mach speed’s high ends via upscaling, but Sukuna himself likely upscales Gojo’s microsecond perception anyhow, and this isn’t even mentioning the potential FTL arguments Sukuna’s got, not even mentioning him likely being even faster at his peak.

So overall, the cards favor the King of Curses when it comes to stats. For Power and Durability, Sukuna has straight up far better feats he can scale compared to Muzan, likely even an AP stomp. Upscaling arguments for Muzan’s Infinity Castle scaling would be canceled out by Sukuna’s own upscaling from Gojo’s nation powering, and none of these factors in the higher end feats Sukuna has from Kenjaku and Yorozu. Speed is a closer category depending on if you buy FTL. If you don’t, then Sukuna would be faster anyhow, but if you buy the EM Wave dodging then he’d blitz. So no matter the ends you use, as long as you’re equally fair to both combatants, Sukuna takes this category.

Abilities

Both Muzan and Sukuna have several abilities and counters which can potentially secure a win for either. Let us take a look at both combatants and what they bring to the table:

Muzan

Muzan can potentially sense the invisible Dismantle slashes from Sukuna by sensing their movement in the air. This is how Maki from Jujutsu Kaisen reacts to Sukuna’s attacks. It is also possible he could use his own blades to parry them or use the suction effect of his mouths to divert them. Dismantle exists physically and can be parried, as has been done by Kusakabe, Maki and Mahoraga. Muzan likely would know how to counter after being exposed to Dismantle even a single time given his experience with flying slashing attacks (like his subordinate Kokushibo’s slashes).

Given that Muzan can regenerate from a single piece of his body (as small as 1/300th of a human head, it is unlikely Dismantle or Cleave can permanently kill him. Muzan’s regeneration does not use any stamina, so he will keep healing from any cut. The World Slash is a decent threat, since it ignores durability. However, the World Slash most of the time leaves behind debris and pieces of what it hits. Twice when used on a human opponent it has split them in two. It can be healed from, as shown by Higurama. Unless the slash covers Muzan’s entire surface area he is likely to heal from it. To be fair such a slash is possible, but Sukuna rarely deploys it to cover such a wide area. In regards to Malevolent Shrine, Muzan can pull a Gojo and fight through it while continuously healing due to the speed of his regeneration. Divine Flame used without a domain is noted to be slow and can be dodged.

Muzan’s offensive options are Absorption, his Shockwave Blood Art, and his blood. While Muzan isn’t known to open with his shockwave, once he does use it becomes a possible match decider. Sukuna on several occasions has been affected by mental attacks and paralysis. He does not have the benefit of being able to transfer mental effects to a host in this fight. Muzan’s shockwaves affect the nerves in the brain and throw body functions like breathing into disarray. While Sukuna can function without his heart, his brain is a different story. Combine the fact Muzan in a healthy state can spam the Shockwave without a cooldown and Muzan has Sukuna pinned down.

When comparing Sukuna’s resistance to blood and Muzan’s cell destroying blood, the best reference we can use is the Curse technique called Rot. Rot takes about 10-15 minutes to kill a target and a few more hours to decompose the body down to the bones. In comparison Muzan’s blood in smaller doses takes about 5 minutes to kill its target while also destroying their cells, and larger doses (which can be transferred into the target by a simple finger poke into the skin) will disintegrate the body immediately. Muzan also keeps his Thigh Blades hidden for surprise attacks which could be used to force his blood into Sukuna's body. Sukuna has a history of being caught off guard by surprise attacks, whether it be Gojo’s red, Yuta using Cleave or Yuji’s explosive blood.

While Sukuna is stated to resist all toxins, this is only in reference to toxins that exist in JJK and the more potent ones that exist in Demon Slayer. It may also be possible for Sukuna to use RCT to remove the toxic blood from his body as Hakari once did. However Hakari pulled it off via his far faster RCT and Sukuna would identify the toxin first to remove it while having to deal with more toxin infused attacks from Muzan at the same time. Muzan could also use his Blood to try to turn Sukuna into a demon and control him with his Curse. Sukuna might try RCT to counter this but it is unknown if it can do so. Sufficient damage caused by the toxin also risks impairing Sukuna’s healing factor.

Lastly Muzan can absorb Sukuna into his body. Muzan has used absorption to absorb a thorn art that impaled his body and his absorption works on the cellular level. Sukuna has no resistance to such absorption and as shown with Douma it is rather quick. The only issue is that Muzan does not use this often in combat and Sukuna could likely counter the attempt by using Dismantle (which he can do so without needing to move). This brings us to…

Sukuna

While Muzan might be able to sense Dismantle, Sukuna could still overwhelm him with numerous blades at once. Regular Dismantle has shown to be able to turn Mahoraga into a pile of blood, which likely exceeds Muzan’s regeneration capabilities. The threat becomes far worse when factoring in Malevolent Shrine. The constant swarm of slashes would be hitting Muzan every second, and while he might be able to fight through it like Gojo did with RCT (given his own regen speed), MS can just turn him into a pile of blood. This leads to Divine Flame which when paired with MS causes a massive detonation. While Muzan has healed from a massive explosion before, Divine Flame exceeds its range and potency. Divine Flame overcame Mahoraga’s regen (who can return instantly from being a pile of blood) and burns hotter than Jogo’s flames which can turn large buildings into molten metal. While Muzan can survive the heat from Red Blight Blades, they still harm him and even slow down his regeneration, a potency which Divine Flame exceeds. If by some miracle Muzan survives Sukuna can just cover his whole body in a World Slash and erase him from existence. Sukuna can stop Muzan's attempt at escaping (via self splitting) by erecting a barrier for his domain or just continuous slashing from Malevolent Shrine.

Sukuna also has a massive advantage in the form of air bounce. This move would allow him to move around Muzan's many whips and make closing distance or keeping distance far easier for Sukuna than it would be for Muzan.

Regarding Muzan’s Shockwave, it might affect Sukuna for a moment but he can just heal from any damage it causes. Tanjiro countered the effect by using Nachirn steel on himself. Sukuna can simply heal the effects. He has shown the ability to fix most (just not the part responsible for Domains) of his brain after it was left in tatters by 10 seconds of Unlimited Void. It was noted his brain was in the exact same state Gojo’s was. This was what both of their brains looked like. Sukuna healed damage that affected his motor reflexes, amongst other functions. Tanjiro also shows it is possible to keep moving after being hit point black by the Shockwave. Despite losing his arm he still impaled Muzan. It is unlikely the Shockwave will keep Sukuna down.

In regards to Muzan’s blood, Sukuna likely would counter it. He is not affected by the poison effect of piercing blood and is generally immune to toxins. RCT can also be used as an option to counter the toxin. While Muzan’s poison is stronger than poisons in JJK, doses can take up to 5 minutes to affect the target and Sukuna can kill him well before then. Muzan is unlikely to get a large dosage in as Sukuna would just chop the body part wants to use to insert the toxin. Sukuna also likely resists an attempt to turn him to a demon via RCT and could just break out of the Curse with sufficient will power. Nanami has also shown that experienced sorcerers can protect their souls and in turn their body from transmutation by using their Curse Energy. Sukuna can also just amputate a body part (so long as it's not the head) that gets infected with the blood with dismantle and then just grow a new one. He did the same thing (by cutting off his hand) to deal with Higurama's blade, which causes instant death to whoever it stabs. Sukuna can also regenerate from partial vaporization of his body, as shown by him immediately recovering from Jacob's Ladder which was visually burning off all of his skin. Sukuna can also survive without his Heart, should he ever get cellular damage to the cardiac area.

As mentioned earlier Sukuna can counter an attempt to absorb him by using Dismantle with no movement or using Cleave on Muzan if he comes near. If Sukuna ever needs to make some distance he can use Cleave Spider Web on the ground. If by any chance his RCT output falls and he is pushed into a corner, he could end up in a mental state where he starts unleashing Black Flashes upon Muzan. If even 2 connect Sukuna can restore his RCT output. 

One final note is about the use of their abilities. Outside of Muzan's demonic blood, Sukuna tends to use his win cons such as Malevolent Shrine and World Cleave more often and even as his open move. Meanwhile, Muzan tends to save abilities such as his paralysis shockwave and absorption far later in his fights which does not help him in this scenario. The only ability Sukuna really tends to save is Fuga but it tends to be used the moment Sukuna finds it to be what he needs like Muzan and his win con abilities.

All in all while Muzan does have several abilities that can wear down Sukuna and potentially kill him, Sukuna has enough counters and his offensive hax are far more useful. The range and potency of MV and Divine Flame exceed the capabilities of Muzan’s regeneration and Sukuna’s RCT helps out against the Toxin and Shockwave effects. Sukuna just has the edge in abilities.

Tertiary Factors

Tertiaries is roughly an even split between the two. In terms of overall experience, Muzan takes it no question. He’s lived for thousands of years and always in operation, whereas Sukuna has only lived through his original lifespan before splitting himself into twenty fingers for a thousand years prior to being incarnated again. Similarly, Muzan should take intelligence, both being incredibly book smart as a chemist and also plotting against the Demon Slayers for centuries all while hiding in the shadows for his next move. This isn’t to say Sukuna’s an idiot, him planning his revival and possessing Megumi for his technique is incredibly impressive, but he’s just not had as much time on earth to compare to the King of Demons to compare.

However, when we start to look at combat is where things begin to favor the Sorcerer. While Muzan lived for far longer, a lot of it was him hiding away and him rarely engaging in combat. In contrast, the King of Curses has fought and slain many sorcerers across his lifespan, including many clans and some of the most powerful foes of his era. At his best, Sukuna has learnt entirely new ways to apply his techniques such as destroying and regenerating his brain or learning World Slash just from glancing, and the many sorcerers he’s fought and killed (even being compared to the Millenia-old Kenjaku through him admitting he couldn’t beat Gojo) should compare to even the best skill scaling Muzan has.

Lastly for stamina, this favors Muzan but isn’t a factor. Demons have many statements of not being affected by stamina, so Muzan obviously takes this category by default. However, Sukuna’s demonstrated incredible stamina in his own right, having fought the entire Shinjuku Showdown cast across multiple rounds while not showing any signs of being tired, and even still has enough Cursed Energy on the level of Yuta by the time of their rematch. Needless to say, while Muzan has no stamina limit, it’d be nigh impossible for it to ever come to him outlasting Sukuna even disregarding the stat gap.

Ultimately, tertiaries are roughly a tie here, likely favoring Sukuna slightly for a combat scenario. Sukuna holds the edge when it comes to combat history and intelligence, while Muzan’s at an advantage for overall smarts and experience.

Conclusion

Overall this fight is much closer than one would think just by looking at the match. Sukuna holds stats for sure no matter what ends are bought as just scaling Sukuna to Gojo surpasses even the highest stats for Muzan (Mach 2915.5 and 94 Megatons easily surpassing 8.8 Megatons being generous, likely far lower and Mach 1420.32). Both also get around equal leeway in upscaling so it's not helping either out. This is also not including higher ends for Sukuna like Sukuna dodging Kashimo’s EM Waves, Kenjaku resisting a blackhole and Yorozu’s Perfect Sphere. All feats that are pretty valid and viable for Sukuna, along with being feats he would easily scale to. The abilities are however what really decide this fight. Both have win cons using certain abilities. Sukuna can use Malevolent Shrine, Fuga and potentially even World Slash to get the job done while Muzan can use his Shockwave and either Demonic blood transfusion or absorption. Their other abilities really only help to set up these win cons as Sukuna’s stats makes most of Muzan's other options ineffective and Muzan’s regeneration cancels out most of Sukuna’s other abilities. However with Sukuna’s speed and willingness to use his powerful abilities as an opening move, it's much more likely he pulls out a win. The tertiary Factors support this further as while Muzan is experienced and intelligent, Sukuna is much better in combat as he's been more willing to fight and put himself in harm's way while a lot of Muzan's strategy in verse is hiding away.

In the end Muzan was a surprisingly solid match for Sukuna, having real win cons and the ability to negate most of Sukuna’s moves. However, Sukuna’s stats, use of win cons and better battle experience ended up being too much for the king of all Demons. Muzan will be saying “Curse you Sukuna”, because he has just been slain. The winner is the King of Curses, Ryomen Sukuna.

Thank You/Next Time 

You hate to see another Demon Slayer L. As usual, thanks to you, the reader, for giving us your time and listening to the hard work of the team. Everyone had a role to play but extra thanks to door-kun, Cabbage, Cyber, Round 1 Fight and The Cardinal King for putting in a huge amount of work for this blog making my life 10 times easier. This blog was made out of a love and passion for both franchises. I became a huge fan of JJK recently (Its peak what else can I say) and with Demon Slayer being my first ever anime I had a lot of attachment to this really cool idea. So I am very happy so many people came together to make this blog a reality. Now for the next time…
