Muzan Kibutsuji | Demon Slayer Kimetsu No Yaiba

Only feelings are eternal and unbreakable. It’s true. I don’t remember a single human being I killed. The flesh dies and that’s the end. However…their feelings passed and never fell apart and even defeated me. I witnessed this happening with my own eyes and was so moved that I trembled. Only feelings are eternal and unbreakable. It’s true. I don’t remember a single human being I killed. The flesh dies and that’s the end. However…their feelings passed and never fell apart and even defeated me. I witnessed this happening with my own eyes and was so moved that I trembled.

Muzan Kibutsuji to himself in The Demon King.

Muzan Kibutsuji is the main antagonist of Demon Slayer: Kimetsu no Yaiba. He is the Demon King, the first of his kind, as well as the progenitor of all other existing demons. [Muzan is also the leader of the Twelve Kizuki, an organization made up of the twelve strongest demons who are directly subordinate to him.

A millennium ago, in the Heian era, Muzan was turned into a demon during an experimental treatment to cure his terminal illness, and his goal since then has been to live without the fear of death and become truly eternal. He plans to accomplish this in two ways: find the blue spider lily or create other demons in the hopes that one day one of them will be able to overcome their weakness of the light of the sun. sun.

As the Demon King, Muzan can control anyone who assimilated his blood to become demons, with Nezuko Kamado, Tamayo, Yushiro, and later Chachamaru being the only exceptions. It is later revealed that Muzan is of the same lineage as the Ubuyashiki family.

Appearance

Muzan’s physical appearance resembles that of a tall, fairly muscular man in his twenties, with abnormally pale skin that can be easily mistaken for unhealthy and sickly skin, curly black hair, and lively eyes. almond shaped. Its pupils are vertical, like those of a cat, and colored plum red. He also has blue, sharp fingernails on his hands.

In his first appearance, Muzan wore a white fedora with a red ribbon and a somewhat extravagant outfit. The outfit consisted of an embroidered black tuxedo and white tie over a black shirt and white pants. He also wore black loafers. As seen in Rui’s flashbacks of meeting Muzan, the Demon King had a slightly different hairstyle and outfit than when he first appeared. When he met Rui, Muzan’s hair was straighter and parted in the middle. He also wore a baggy tuxedo and a white half cape over it.

During his encounter with the lower rank demons, he arrived disguised as an elegant woman wearing a long black yukata, which caused the lower rank demons to not recognize him. He later transformed into his latest cover identity – the ailing adopted son of an old couple – taking the form of a young child aged 10-11 with pale white skin and dark, silky hair. and neatly combed. His primary outfit in this disguise is a simple white button-up shirt and black cargo shorts with long tube socks and loafers.

After neutralizing Tamayo’s poison and emerging from his flesh cocoon, Muzan’s hair grows longer and turns white, with Shinobu’s poison accelerating his aging. Numerous mouths also sprout from its limbs, each of which has a series of impossibly sharp fangs. His skin also appears to have a dark red mass that grows out of the tips of his limbs and branches out over his body. It is later revealed that Muzan has a set of scars all over his body from the wounds inflicted in his first fight against Yoriichi, which were burned into him down to a cellular level and never fully healed despite hundreds of years. These wounds are not visible in broad daylight and are revealed as he weakens.

During his final fight, and to slow the effects of the sun, Muzan adopts an enlarged demonic baby form, about as tall as a three-story building when standing. In this form, he has very pronounced blood vessels all over his body, small claws in his hands, and hooked teeth in his mouth.

Personality

Muzan is heartless, ruthless, intimidating, and exceptionally intelligent. He sees no value in the humans he has encountered and shows little value in his own subordinates. Rarely visually upset or happy, he appears completely monotonous and detached on most occasions, even when he mercilessly murders his own subordinates. The only times he shows emotions are when his vision of perfection progresses or when his subordinates completely submit to his will. The manga shows him to be more expressive, particularly when enraged, and his facial features are exaggerated to demonstrate this (perhaps as a way to display his normally indecipherable emotions). In the anime, his expressions change slightly and his tone of voice is almost always the same, which accentuates its monotonous behavior. His cruel and imposing nature earns him the great admiration of many demons.

His inflated ego and delusional sense of self-worth are so great that he can’t stand being laughed at or corrected in any way, because he believes other people only exist. to serve him. It also means that he rarely takes any opponent or threat seriously. He brutally killed two drunken men simply because they were rude to him, and killed their companion when she had done nothing, while proclaiming his own perfection and superiority over them, showing his pettiness as he will not be satisfied with any mockery and will do whatever pleases him until the humiliation is repaired. This event also suggests that Muzan has unpleasant memories of his weaker human past and is very aware of his abnormally ill appearance. which immediately leads him to a lengthy denial that he is in poor health, sick, let alone about to die. In all likelihood, it’s a bitter reminder that he’s still flawed. When confronting Kagaya Ubuyashiki, the man responds to Muzan in a tone of pity and sadness for the life he has led. However, Muzan only interpreted it as insults and threats, which further accentuates his hatred of humanity and Demon Slayers. He also believes that Heaven left him alone for the murder of thousands of people, because he never saw a God or a Buddha. the man responds to Muzan in a tone of pity and sadness for the life he has led. However, Muzan only interpreted it as insults and threats, which further accentuates his hatred of humanity and Demon Slayers. He also believes that Heaven left him alone for the murder of thousands of people, because he never saw a God or a Buddha. the man responds to Muzan in a tone of pity and sadness for the life he has led. However, Muzan only interpreted it as insults and threats, which further accentuates his hatred of humanity and Demon Slayers. He also believes that Heaven left him alone for the murder of thousands of people, because he never saw a God or a Buddha.

Muzan’s most prominent trait is his extreme narcissism, pettiness, and obsession with becoming the perfect being. Since he’s had nearly 1,000 years to live and observe, and hardly faced any real challenges, his extreme self-centeredness is almost normal. He doesn’t care about anything except overcoming his inability to walk in the sun, which is his primary motivation. His long life and obsessions have led him to want every plan he concocts to be absolutely perfect, and his god complex prevents him from seeing his own failures. His belief that he is the closest thing to a perfect being leads him to have zero tolerance for any failure, brutally punishing those who disappoint him or those he considers weak, even if the failures are minor. .

Also, his delusional sense of omnipotence is such that he compares himself to natural disasters, that is, to something that is far beyond what humans can compare and fight against. That’s why he thinks the demon slayers are a bunch of deviants who can’t accept the natural order of things and go back to their lives as if nothing had happened when other people just move on. after a tragedy. His analogy speaks to his utter inability to feel sympathy or remorse for his actions, given that none of the murders he committed (directly or indirectly) were the result of accident, but acts of carefully orchestrated pure malevolence.

Behind the myriad facades Muzan displays, and in stark contrast to his insatiable ego and thirst for perfection, Muzan is incredibly cowardly. He always avoids conflict, as evidenced by his meeting with Giyu Tomioka and Tanjiro Kamado. He states that the duo that manages to survive should already be enough and that they should just live to earn their wages and end the cycle of revenge. This trait also complements his manipulative nature, which allows many demons to be bent to his will, without him getting his hands dirty. In the Sunrise Countdown arc, Muzan tried numerous times to escape, either by splitting or simply running away.

He was shown to be quite manipulative and cunning, able to blend in normally with human society, even having a family of his own. A long life and continuous practice have enabled him to take on many roles in society and play them skillfully, including that of a child and a wife if he so chooses. This life also gave him great intelligence and the ability to think tactically. Muzan is a quick thinker and strategist who is able to deal with adverse situations quickly and fairly well, though it could also be because losing his subordinates means nothing to him in the long run.

Due to his perceived superiority and two-sidedness, he holds little attachment to his minions, using and discarding them as disposable pawns when he sees fit. He does not allow his subordinates to question him, regularly inflicting brutal and ruthless punishments on them if they do. Many of his subordinates, in turn, are deeply afraid of him and carefully measure their words and thoughts lest they say anything that might displease him. He is able to rally many demons to his cause by promising them power, revenge and greatness, provided they serve him. His intelligence and manipulation shines here, as many find the promises appealing, as he meets many of his subordinates at the lowest, when their emotions are easy food for him. Alas, all of these promises are ultimately false, since Muzan only cares about himself and has no qualms about killing his own men to protect his own safety.

When he’s not hiding behind a facade, his sheer malice and overflowing violent intentions are so incredibly cunning that they can be seen by others. Yoriichi Tsugikuni notably described it as a boiling magma coming out of a volcano.

Beyond his self-centered behavior lies a sense of self-preservation that easily outweighs his megalomania, terrifyingly cursing his subordinates so that none of them utter his name, or else they be killed instantly in a ruthless manner. When pushed against the wall, Muzan’s calm, arrogance, and superiority crumble, giving way to panic and fear. This obsession with survival may well explain Muzan’s brutal killing of three civilians after his first encounter with Tanjiro. Both times he recalls two major events where he nearly lost his life.

Whatever Muzan’s flaws, he always showed a strong taste for fashion and higher education. Whenever seen outside of combat, he comes across as an extremely well-dressed individual. In his Tsukihiko guise, he wears a fedora and a suit. Interestingly, his “wife” Rei is depicted with a cloche hat (beater’s hat). In his Toshikuni guise, he wears buttoned pants and a shirt, and is seen studying a lot. When he talked to the senior brass, he carelessly mixed various chemicals, which shows that he is an expert in chemistry,

Later, during his defeat and his final moments as he is burned by the sun, Muzan shows a much more vulnerable side of his personality as he slowly disintegrates into ashes and laments his life and choices. . It is revealed that Muzan’s true fear of dying and his overwhelming desire to live and survive was due to the fact that he was born “dead”, his heart constantly stopping in his mother’s womb and he was considered stillborn until he struggled to breathe before his cremation. Muzan’s desire for “life” and his near-constant struggles as a human built his obsessive ambition to survive, and he felt genuinely vulnerable whenever he was reminded of his human frailty. Even when he’s on the verge of death,

However, as Muzan reflects on his life while dying in the sun, he comes to understand and accept Kagaya Ubuyashiki’s words that everything dies inevitably and the only true “immortal” thing in the world are a person’s emotions, feelings and memories. This realization brings Muzan to tears and genuinely touches him, causing him to ironically embrace Yoriichi and Kagaya’s belief and focus on leaving “something” behind in order to truly become “immortal”.

Skills

General Abilities: As the first demon to exist and as the progenitor of all demons, Muzan is the strongest demon in existence and possesses enormous power and attributes far superior to those of the Twelve Kizuki. His immense abilities were on display when he was able to stand up to five Hashira and Tanjiro, Inosuke, Zenitsu, and Kanao at the same time. He is then able to put Tanjiro in a near-death state using his poison in a single attack and would have nearly killed Mitsuri, an incredibly strong Hashira, had she not been rescued by other Demon Slayers. Gyomei, Giyu, Sanemi, and Obanai would also have succumbed to its poison and died had they not received antidotes from Chachamaru. After about 30 minutes of fighting the Hashira, Muzan manifested leg whips, which increased his attack speed exponentially, to the point of instantly defeating exhausted Demon Slayers. However, it is later revealed that Muzan is gradually becoming slower due to Tamayo’s aging drug, which affected him throughout the battle. Despite this, he was able to easily defeat the Demon Slayers and gain the upper hand over Tanjiro, who had mastered the Breath of the Sun.

Biological absorption: Muzan has shown the ability to absorb, assimilate, and dissolve organic and inorganic objects, as seen when he began to absorb the flesh seed thorn branches pierced into his skin, or when he started absorbing Tamayo and dissolving his drug. It is also seen when he planned to eat and assimilate Nezuko Kamado to gain his immunity to the sun. He adapted to become immune to being decapitated by blades created with sun-infused metal. He’s also surely able to adapt to poisons even better than the higher-ups, who became resistant to the wisteria poison that kills normal demons in seconds, and he was able to adapt to resist a drug specifically designed for turn demons back into humans.

Combat Form : When in combat, Muzan can take on a more monstrous form, with a dark red mass covering his limbs, with large, sharp-toothed mouths, and an exposed torso. His hair is getting longer, and messier. His speed, strength, reflexes, and power are greatly increased in this form, so much so that, despite losing much of his stamina and stamina by fending off Tamayo’s human transformation drug, he was still able to easily outsmart several lower-ranked Demon Slayers and devour dozens of them within minutes of emerging from its cocoon.

In this form, he is also strong enough to create huge craters in the ground or destroy entire pieces of buildings. The sharp-toothed jaws/mouths located all over his body in this form not only serve as his primary form of attack in battle, but also serve the purpose of helping him recover faster since he can use the jaws to tear his opponents and eat their flesh, simultaneously killing his opponents and regaining his strength.

• Arm Whips: Muzan can stretch his arms and grow multiple sharp blades in his extended forearms and transform his hands into multiple sharp protrusions, each ranging from 90 centimeters (35.4 in) to 10 meters (32.8 ft) , which he can then swing like whips to easily shred his opponents. The rotation speed of his attacks is extremely fast, and the accuracy of his attacks is also extremely precise. And, due to the length of his arms, Muzan has such an attack range that not even three Hashira can get close to him.

• Mouth Suction : Muzan’s arm whips also possess numerous mouths filled with sharp fangs. Muzan can use these mouths to breathe with absurd force and a suction force that he can alter at any time from extremely long distances, which he uses to lure opponents into his arm whips’ striking range. This greatly hinders Hashiras’ movements, as dodging them consumes much more stamina.
• Leg Whips: Muzan then grew 4 tubes on each thigh, each 7 meters (22.9 ft) long. Unlike spinal whips, they are much faster, and with his immense shapeshifting talent, he can make them grow rapidly and dissipate them faster than human senses can perceive, allowing him to attack easily in blind spots, as evidenced by the fact that he managed to use them to critically injure four Hashira and Hashira-level Demon Slayers without them sensing or perceiving that Muzan’s body had altered and metamorphosed .
• Thorn Whip : Later, when even more enraged, Muzan grows 9 slender tubes, each 4 meters (13.1 ft) long, similar to spine-like protrusions that extend into tentacles in whip shape. Thanks to them, Muzan is able to greatly increase the range and number of his attacks in tandem with his whipping arms, allowing him to easily mow down hordes of Demon Slayers and pin down four Hashira. Additionally, it’s incredibly difficult to read the trajectory of each of his whips, making them even harder to counter.

demonic blood: After consuming the Blue Spider Lily, Muzan developed supernatural blood with special properties that can turn humans into demons when ingested. His special blood also seems to give rise to a plethora of special abilities unique to demons, such as powerful regeneration, the power to shapeshift, immortality, accelerated growth rate, enhanced physical prowess, and even supernatural abilities called Blood Demon Arts. Muzan can also enhance a demon’s power by giving them more of their blood, which enhances their pre-existing abilities. However, this is limited to the amount of blood the recipient can withstand and adapt to. If a human were to absorb too much of Muzan’s blood, their body would mutate faster than it can handle, which would cause him to self-destruct into a giant mass of flesh before disintegrating into ash. The same would presumably happen to a demon if it couldn’t resist the effects of blood, as Muzan implies.

Later, it was revealed that Muzan learned to use this particular characteristic of his blood as a weapon. By coating attacks with his blood, he could inject his blood into an opponent during combat through the wounds he makes. The dosage would be too high to handle and would act like a poison that would destroy human body cells soon after entering. It is later revealed by Kokushibo that Total Concentration Breath users resist the effects of Muzan’s blood more than normal humans.

• Blood memory transfer: In his final struggle for survival, Muzan is able to transfer the rest of his blood along with his memories into a suitable body, turning his new host into a demon and wielding his influence. He managed to do this with Tanjiro as he was about to die, restoring his damaged body and causing him to lash out at his comrades. Additionally, this technique is compatible with the host’s own abilities, causing Tanjiro to not only be able to use the demon’s abilities but his own as well, since he gains immunity to sunlight and potentially the use of the Breath of the Sun. This transfer, however, is not perfect as Tanjiro has been reduced to a feral state, only attacking based on Muzan’s desire to kill the Demon Slayers.

• Demon Manipulation : Muzan can control demons to some degree, as seen when he was able to take control of Nakime’s body in an attempt to force Yushiro’s cells to be absorbed in order to stop his meddling when attempted to usurp control of Infinity Castle. However, this ability requires great concentration, as Muzan immediately lost control of Nakime as soon as he lost his concentration due to having to defend himself in the midst of combat. Other demons can also take control of him.

• Demonic Curse: Muzan possesses the ability to place a curse on demons who have assimilated his blood. If a demon he created speaks his surname “Kibutsuji” out loud, the curse activates and three demonic arms erupt from their body and destroy them, regardless of their original intent. This is what happened with Susamaru, who accidentally said his name when he had no malicious intent towards him and was still destroyed by the curse, implying that the curse is automatic . We saw it when he killed Nakime, who was manipulated by Yushiro. For this reason, many demons serve Muzan out of fear and respect, simply calling him “that man” or “him” when referring to him. However,
  • Access to Demons’ Memory : Muzan is able to “see” the memories of demons he has absorbed, such as when he was able to “ask” Tamayo’s cells he obtained by absorbing him for information about the type of drug she had injected him with. After facing rejection and insults from Tamayo’s surviving conscience, he has also shown the ability to forcibly reveal desired information by “looking” at his memories, such as when he was able to see his memories of the setting. at the point of medicine with Shinobu Kocho and Yushiro.
  • Demon Power Nullification : As Tamayo explains, as the creator and progenitor of the demonic race, Muzan is the only known demon capable of inflicting lethal wounds capable of completely destroying the cells of other demons without resorting to the use of Nichirin swords or sunlight. This was shown when he punished Akaza by causing extreme lacerations all over his body without the High Rank being able to regenerate like he would any other injury.

• Possession:As later seen in Tanjiro’s consciousness as a demon, Muzan can actually implant a small portion of his consciousness into a demon he creates using his blood, provided he injected them with gigantic quantities of his blood when they were created. As can be seen when a piece of his spirit was still present in Tanjiro’s mind despite having already been killed by the sunlight, and then tried to influence, control and to possess Tanjiro so that he “inherits” his will and remains a demon. However, the difference between his power to “control” a demon and his power to “possess” it is that he can no longer take control of a demon by force and force it to do what it wants. , but that he must convince him to carry out his orders,
• Telepathy: Muzan has the ability to read the thoughts of those he shared his blood with by looking at them. Later, it was shown that he could also send telepathic messages and have full conversations with other demons, as seen when he communicated with the top Rank 1, Kokushibo, to check how many Hashira he had defeated and ordered him to hold them off until he was done recovering from Tamayo’s poison. Muzan also said that he could sense the location of all the demons. However, the further away they are from him, the more difficult it will be for him to interact with them and keep up with them. Muzan is also able to see through the senses of other demons. However, this ability is strictly limited to what is in their perception,

Extrasensory Perception : Muzan possesses extremely acute senses that even allow him to perceive things outside of the normal range of perception, which he demonstrated by easily discerning the presence of humans instantly even if they were scattered all around. up a mountain and sensing the injured Demon Slayers who were regaining consciousness despite the distance between them. This was also shown when Muzan was able to discern the locations of Zenitsu, Kanao, and Inosuke with great accuracy solely from the clouds of dust rising and the sounds they made.

Brilliant Intellect: Having lived for over a millennium and gained further experience through telepathic bonding with the demons he controls, Muzan is extremely intelligent and learned. Since he has 5 perfectly functioning brains, it is highly likely that his intelligence and other mental abilities, such as memory and cognitive processing, will be enhanced. He was also able to evade the Demon Slayer Corps for almost a thousand years, though the leaders of the corps, the Ubuyashiki Family, possess great foresight and intuition. He also used demons to create distractions in remote locations when he wanted to hide something from the body. Muzan has proven himself to be a master of manipulation. As a human,

As a demon, Muzan is able to manipulate people without them realizing it, such as convincing Susamaru to fight into believing she is a member of the Twelve Kizuki or encouraging Daki to kill Nezuko Kamado. by influencing it with words. Muzan is also a master in many scientific fields, such as chemistry and possibly biology, experimenting with chemicals in an attempt to find a cure for conquering the sun. He also enjoys importing goods, learning foreign languages ​​and studying newly invented machines. Finally, Muzan is able to impersonate wealthy and influential individuals, regardless of gender or age,

Immeasurable speed and reflexes: Muzan is extremely fast, possessing movement speed and reflexes that surpass those of the upper ranks of the twelve Kizuki. During the Infinity Castle Arc, even after being weakened by a drug specifically designed to defeat him, he was able to slaughter dozens of Demon Slayers before they could even react. Additionally, Muzan was so fast that Tanjiro and Mitsuri couldn’t even see them and could only rely on luck and instinct to dodge his attacks. He was also able to hold his own against a dozen Hashira-level Demon Slayers. and Hashira for a long time, while being weakened by anti-Kibutsuji drugs. Moreover, Muzan was able to unleash an attack so fast that Giyu, Sanemi, Obanai, Gyomei, Zenitsu,

immeasurable strength: As the King of Demons, Muzan’s physical strength is stronger than that of all existing demons. He demonstrated this when he killed a grown man with a single punch to the face, sending him flying backwards, hitting a building and cracking it. He also managed to kill a taller man by simply kicking him. Even after being severely weakened by the many drugs that weakened him, he possessed enough physical strength to destroy huge sections of buildings, create huge craters in the ground, and quite easily lift debris from the buildings that imprisoned him. . In his infant form, he could crush vehicles and could only be held down by the combined efforts of Gyomei Himejima, the Hashira possessing the greatest physical strength,

Near-Absolute Regeneration : As the progenitor of all demons, Muzan possesses the fastest and most advanced regeneration in existence, recovering so quickly that he appears to have never been harmed. He has demonstrated his ability to regenerate flawlessly on multiple occasions. Muzan notably overcame the weakness of being decapitated by Nichirin swords, as evidenced by the fact that he completely pushed his head back moments after it was pulverized by Gyomei’s spiked flail. After being caught in a huge explosion orchestrated by Kagaya Ubuyashiki, Muzan was able to instantly regenerate his body after extensively damaging it and was also able to bypass the metal spikes added in the explosion meant to slow his healing speed. .

Later, during his fight against the three Hashira Obanai, Mitsuri and Giyu, the latter dealt multiple blows to the Demon King, but to no avail, as Muzan regenerated the moment his body was sliced, giving the impression that their attacks had not borne fruit, which is all the more impressive since he had already been weakened by the drugs administered by Tamayo. Additionally, his regenerative power was still functional even when cut by the Hashira with their bright red Nichirin swords, though the recovery process was slower than usual. Perhaps Muzan’s greatest feat of regeneration is having his body completely regenerated from a piece of flesh the size of a human head.

Unlimited Resistance and Stamina : Like all demons, Muzan possesses absolute and infinite resistance and stamina, remaining in peak physical and mental condition at all times and being able to endure waves of assaults as if it were nothing. . This was demonstrated when he did not flinch or show signs of pain or agony when he was slashed and pierced by the Hashira’s bright red Nichirin swords, which caused immense pain to Kokushibo himself.

blood demon art

Biokinesis : Muzan’s Blood Demon Art grants him powerful biokinetic abilities. Muzan has demonstrated the ability to alter and control his flesh, limbs, and even his organs. Using his Blood Demon Art, Muzan can alter his facial features, replicate and move his body organs, create weapons using his flesh and bones, transform his entire torso into a giant mouth , or even create puppets of flesh that he can control. He can also split into hundreds of pieces that can reattach and regenerate to form his complete body.

Muzan also has a very particular anatomy which he obtained by manipulating and modifying the properties of his own body. Possessing a grand total of seven hearts and five brains, these extra organs are apparently largely responsible for the majority of his abnormally powerful build and resistance to decapitation by Nichirin swords. Conversely, if several of them were destroyed simultaneously, it would be significantly weakened. In combat, Muzan usually fashions his arms into long whip-like appendages as sharp as swords and creates tubes and whips made of bone and flesh from his spine and legs.

After being pinned down by the Demon Slayers and immobilized by Tanjiro until daybreak, Muzan in a panic caused his flesh to swell to the point of resembling that of a gigantic infant, in an attempt to protect his body. principal of sun burns. This form was shown to possess immense physical strength likely due to his size, as seen Muzan was able to easily crawl through and push back an entire car that had been pushed by several of the Kakushi, and later moved on. was able to break Gyomei’s chain, something even Kokushibo couldn’t handle with his katana, despite holding Muzan back from him with all his might and with the added support of several Kakushi.

• Shapeshifting: Muzan possesses the strongest and most advanced shapeshifting ability of any demon in existence. Not only can Muzan change his appearance perfectly, but he can also alter his aura and presence, which can even fool the enhanced senses of lower rank demons. He used this ability to transform into a woman, a child, and even a large cocoon of flesh.

fighting style

Black Blood, Brambles – Muzan uses his own flesh and blood to create several spiked, barbed black threads to entangle his target.

Shockwave Energy Blast : Later, while cornered by Tanjiro and Obanai and weakened by Tamayo’s four-stage drug, Muzan displayed another unique ability of his Blood Demon Art, transforming his torso and upper of his body into a gigantic beast’s mouth. From there, it released a powerful energy shock wave that damaged the nervous system of those caught in it, causing extreme seizures and convulsions, even rendering them unable to breathe for a brief period. This attack was so strong that when Tanjiro and Obanai were damaged by this technique, even Kiriya and his sisters, who were connected to them through the crows in the area, took the brunt of the attack.

• (To Tanjiro Kamado) “Tanjiro Kamado… You will conquer the sunlight and become the strongest demon, the king of demons! It’s because you are Nezuko Kamado’s older brother and therefore share his blood. You won’t die. I believe him. Make my dream come true… Tanjiro. In my place… you must destroy… the Demon Slayer Corps! »

Information about Muzan Kibutsuji

Muzan Kibutsuji is the main antagonist of the series who used his blood to spawn the other demons, able to manipulate his cellular structure, from manipulating his physical form to frequently disguising himself as different humans of different ages and genders. different down to programming transplanted cells within demons he directly spawned to destroy a host body if they mention him by name. He can also devour other people’s cells to assimilate their abilities and memories. Muzan was originally a sick young man from the Heian period whose transition into a demon was the result of an experimental treatment to prolong his life, killing his doctor before realizing it worked. He has since dedicated himself to “complete his cure” and become perfect by siring demons that would help him achieve his goal. He similarly expressed justified concern for those who use the Breath of the Sun technique since his near-death experience fighting Yoriichi Tsugikuni, which motivated him to slaughter Tanjiro’s family as part of an attempt to turn them into demons naturally immune to sunlight. Nezuko, the sole survivor of the incident, eventually manifests this ability, with Muzan focusing his efforts on capturing and devouring her to eliminate his one weakness. But the Demon Slayer Corps exploit Muzan’s obsession to set a trap for him that kills the last followers. Muzan kills Tamayo and numerous Demon Slayers before learning that he has been infected with a variant of the Humanity Restoring Serum Tamayo and Shinobu have developed with additional poisons that take away most of his abilities and destroy him. weaken so that he is easily killed. His body is therefore destroyed by sunlight when he is restrained by the Demon Slayers to prevent him from escaping. Muzan’s final act of revenge involves turning Tanjiro into a new demon to kill the Demon Slayers, which is thwarted when the boy becomes human again with the help of his friends.

History of Muzan Kibutsuji

Muzan has been diagnosed with a disease that will kill him before he reaches the age of 20. He sought medical help from Blue Spider Lily, but he turned into a demon because of it.

Muzan’s attending physician gave him a prototype special medicine. In a fit of rage, resulting from his worsening condition, Muzankilled the doctor. However, it wasn’t until he killed the doctor that he realized the drug actually worked. He had acquired a strong body. Muzan had no problem adjusting to having to kill other humans to survive, but the problem he faced was the fact that he was unable to walk in the sun. That’s when he really regretted killing the doctor, before he could finish his treatment with his medicine “Blue Spider Lily”. He looked all over the country for the Spider Lily, but couldn’t find it. That’s why Muzan started creating other demons. He planned to spread them around the world, hoping that one of them would eventually find a way to defeat the sun or at least help him in his quest for the Blue Spider Lily.

Around 400 years before the main story, Muzan was nearly killed by Yoriichi Tsugikuni, a Breath of the Sun user, but he eventually managed to escape and survive. Since then, he has been more vigilant and alert to the possibility of encountering Breath of the Sun users, who can be identified by a pair of Hanafuda earrings they usually wear, which has also made the family Kamado a target, as they practice the Fire God Dance, which is the breath closest to the Breath of the Sun. To this end, he hunted, along with Kokushibou, people who might have Hanafuda earrings.

Personality of Muzan Kibutsuji

Muzan is a ruthless individual who wants all his plans to be perfect. He is not nice to his offspring only if they have failed a mission or are incompetent. He also praises those who succeed in their missions. He does not take his enemies seriously. He also does not like to be questioned and commanded by his descendants. He is also narcissistic.

The only times he shows emotion are when his vision of perfection advances or when his subordinates submit completely to his will. The manga shows him more expressive, especially when enraged and his facial features are exaggerated to show him as such (perhaps as a way to display his normally unreadable emotions). In the anime, his expressions change slightly and his tone of voice tends to be constant almost all the time, which accentuates his detached demeanor.

Muzan ‘s most defining trait is his extreme narcissism and obsession with becoming the perfect being. As he has had almost 1000 years to live and watch, with hardly any real challenges, his extreme self-centeredness is almost predictable. He considers almost nothing as his concern, except to overcome his inability to walk in the sun, which is his main driving force. His long life and obsessions have led him to want every plan he conceives to be absolutely perfect, and his god complex prevents him from seeing his own failures. His belief that he is the closest thing to a perfect being causes him to enforce zero tolerance for any failure, brutally punishing those who let him down or those he considers weak, even if the failures are minor.

His inflated ego and delusional sense of self-worth are so great that he can’t stand being laughed at or corrected in any way, believing that others only exist to serve him. . It also means he rarely takes an opponent or threat seriously. He brutally killed two drunken men simply for being rude to him, and killed their companion when she had done nothing, while proclaiming his own perfection and superiority over them. This event hints that Muzan has unpleasant memories of his lower human past, and is keenly aware of his abnormally sickly appearance, immediately followed by a lengthy denial of his health, illness, and even less his imminent death. In all likelihood, it’s a bitter reminder that he’s still flawed. When he finally managed to confront Kagaya Ubuyashiki, the man responded to Muzan with a tone of pity and sadness for the life he had led. In Muzan’s mind, this only translated into insults and threats, which he used to justify his hatred of humanity and Demon Slayers.

Moreover, his illusory sense of omnipotence is such that he compares himself to natural disasters, that is, to something far beyond what humans can compare themselves to and fight against. . This results in him believing the Demon Slayers to be a group of deviants who cannot accept the natural order of things and go back to their lives as if they were normal when other people just go ahead and following a tragedy. His analogy demonstrates his utter inability to feel sympathy or remorse for his actions, given that none of the murders he committed (directly or indirectly) were the result of accident but of carefully orchestrated acts. pure evil.

He was shown to be quite manipulative and cunning, able to blend in normally with human society, even having a family of his own. A long life and continuous practice enabled him to assume many roles in society and perform them competently, including for children and women if he so wished. This life also gave him great intelligence and tactical thinking skills. Muzan is a quick thinker and a strategist who can handle adverse situations quickly and fairly well, though this could also be because losing his subordinates means nothing to him in the long run.

Due to his perceived superiority and two-faced nature, he hardly grows attached to his minions, using and throwing them away as disposable pawns when he pleases. He does not allow his subordinates to question his will, and regularly retaliates brutally if they do. Many of his subordinates, in turn, are deeply afraid of him and carefully measure their words and thoughts lest they say anything that might displease him. He is able to sway many Demons to his side with promises of power, revenge, and greatness, as long as they serve him. His intelligence and manipulation shines here as many find these promises very appealing, as he meets many of his subordinates at their lowest point, when their emotions are easy for him to feed. Alas, all these promises are ultimately false, given thatMuzan only cares about himself and has no qualms about killing his own men to protect his own safety.

When he’s not hiding behind a facade, his sheer malice and overflowing violent intent are so incredibly cunning that they can be seen by others. Yoriichi Tsugikuni notably described it as being like boiling magma erupting from a volcano ready to consume everything.

Beyond his self-centered behavior is a sense of self-preservation that can easily override his megalomania, cursing his subordinates in paranoid and terrifying ways so that none of them can pronounce his name, or else to be killed instantly in a morbid and cruel way. When cornered, Muzan’s typically calm, arrogant and superior stance crumbles , setting the stage for panic and fear, as he desperately fights for his life, adopting more drastic measures to protect themselves. This obsession with survival may well explain the brutal killing of three civilians committed by Muzan after meeting Tanjiro.for the first time, as he was made to recall his sickly past with the former, and his encounter with Yoriichi with the latter, due to his hanafuda earrings, the two major events where he nearly lost his life.

Later, during his defeat and his final moments as he was scorched by the sun, Muzan showed a much more vulnerable side of his personality as he slowly disintegrated into ashes and lamented his life and his experiences. choice. It is revealed that Muzan ‘s true fear of dyingand his overwhelming desire to live and survive were due to the fact that he was born “dead”, his heart constantly stopping in his mother’s womb and being assumed stillborn until he fought for it. breathe before his cremation. Revealing that Muzan’s desire for ‘life’ and his near-constant struggle to breathe as a human built his obsessive ambition to survive, and that he felt genuinely vulnerable whenever he was reminded of his fragility human because of it. Even on the brink of death he is still completely unrepentant in his actions of killing, murdering and eating humans for a thousand years and has even stated that when he died he could not remember. only one person he had killed.

However, as Muzan slowly died of sunlight and his final thoughts on his life, he came to sincerely accept Kagaya Ubuyashiki’s words to him that everything dies in the end no matter what. happens, and that even he would one day experience death as the only truly “immortal” thing in the world are someone’s emotions, feelings, and memories. This realization brings Muzan to tears and sincerely moves him, causing him to ironically adopt Yoriichi and Kagaya’s belief and stance, which instead focuses on leaving “something” behind in order to truly become “immortal”.

Abilities and Powers of Muzan Kibutsuji

As the first Demon to exist and as the progenitor of all Demons, Muzan is the strongest Demon in existence and possesses enormous strength, easily able to stand up to five Hashira and Tanjiro at the same time. He is then able to put Tanjiro in a near-death state using his poison in a single attack and would have nearly killed Mitsuri, an incredibly strong Hashira, had she not been rescued by other Demon Slayers. Gyomei, Giyu, Sanemi, and Obanai would also have succumbed to its poison had they not received Chachamaru’s antidotes. After about 30 minutes of fighting the Hashira, Muzanmanifested his leg whips, which increased his attack speed exponentially, to the point of instantly defeating the exhausted Hashira: Gyomei, Giyu, Sanemi, and Obanai as well as Zenitsu and Inosuke at the same time, while leaving Kanao paralyzed by fear and a broken sword. However, it is later revealed that Muzan becomes progressively slower due to Tamayo’s aging medicine, which affected him for the duration of the battle. Despite this, he was able to easily defeat the Hashira and keep the edge over Tanjiro in their fight who was slowly overpowering the Sun’s Breath.

Demon Abilities

Demon Anatomy: Muzan has a very unique anatomy, even compared to other Demons. Possessing a total of seven hearts and five brains, these extra organs are apparently largely responsible for the majority of his abnormally powerful build. Conversely, if many of them were destroyed simultaneously, it would be significantly weakened.

Instant Regeneration: As the progenitor of all Demons, Muzan possesses the fastest and strongest regenerative power ever seen in the series so far. He is able to instantly regenerate his body after being caught in the huge explosion prepared by Kagaya Ubuyashiki and manages to bypass the metal spikes added in the blast. Moreover, Muzanmanaged to overcome one of the Demons’ main weaknesses, being decapitated by a Nichirin blade, as seen when he easily regenerated his head after it was completely destroyed by Gyomei’s flail did of steel in sunlight. Later, in his fight against the three Hashira Obanai Iguro, Mitsuri Kanroji and Giyu Tomioka, they managed to pressure him and get the chance to behead him. However, his head was already immediately sticking back together even as the blade pierced his flesh, shocking the trio as no other Demon, even among the higher ranks, displayed such strong regenerative powers.

Demon Whip, Muzan can stretch his arms out and push multiple sharp blades into his outstretched forearms and mold his hands into multiple protrusions of blades, which he can then swing like a whip to easily tear his opponents to pieces. The speed of his attacks is extremely fast and the accuracy of his attacks is also extremely precise. And, due to the length of his arms, Muzan possesses such attack range that even three Hashira couldn’t get close to him. These whipped arms also come with pointed mouths, allowing Muzanto inhale a large amount of air with them which he can then use to create an immense suction effect that forcibly pulls his opponents towards him and seriously impedes their movement.

Spine Whips. Later, when even more enraged, Muzan demonstrates a new ability to grow thorn-like protrusions from his back that grow into tentacles shaped like whip blades. Using these tentacles, Muzan is able to greatly increase his range and number of attacks in tandem with his whipped arms, allowing him to easily mow down hordes of Demon Slayers and pin down four Hashira.

Leg Whips – Muzan later revealed that with his ability to freely transform and switch bodies, he can quickly grow eight additional whips from his thighs in order to perform incredibly fast stealth attacks. With his immense shapeshifting talent, he can make whips grow rapidly and dissipate them faster than human senses perceive, as he manages to use them to seriously injure four Hashira and Hashira level Demon Slayers without them feel or perceive that Muzan ‘s body has changed and transformed.

Infantile Form: After being cornered by the Demon Slayers and pinned by Tanjiro until daybreak, Muzan , in a panic, transformed into a gigantic mass of flesh, resembling that of a gigantic demonic infant, in order to protect his main body from sunburn so quickly. This form was shown to possess immense physical strength, as evidenced by the fact that Muzan was able to easily crawl and push back an entire car that had been pushed by several of the Kakushi, and was later able to break Gyomei’s chain, although he restrained Muzan with all his might and was supported by several Kakushi.

Demon Blood: His blood causes all cells in the body of those he enters the body to transform, turning them into demons. This gives them several default powers: enhanced strength and senses, top-down regeneration, eternal youth, and shapeshifting, could eventually give them additional powers. Castrated demons gain blood arts, which can vary from simple wire manipulation to spatial manipulation, but have several drawbacks: the sun reduces demons to ashes, objects imbued with the energy of the sun kill if they are used to decapitate the demon, the wisteria flowers become a deadly poison to them, and they crave human flesh. In the event of an overdose, the cells break down one by one.

Nullifying Demon Blood: As Tamayo explains, as the creator and progenitor of the Demon race, Muzan is the only known Demon capable of inflicting lethal wounds capable of completely destroying the cells of other Demons without having needing Nichirin Blades or sunlight, making him the only Demon capable of completely nullifying a Demon’s natural regenerative abilities and killing them.

Demon’s Blood Memory: In his final struggle for survival, Muzan is able to transfer the rest of his blood along with his memories into a suitable body, turning his new host into a Demon and exerting his influence. He achieves this with the Tanjiro on the brink of death, restoring his damaged body and causing him to lash out at his comrades. Additionally, this technique is compatible with the host’s own abilities, allowing Tanjiro to use not only the Demon’s abilities but his own as well, since he gains immunity to sunlight and potentially the use of the breath of the sun. This transfer isn’t perfect though as Tanjiro has been reduced to a wild state, only attacking based on Muzan’s desire to kill the Demon Slayers.Muzan whenever he created another demon or shared his blood with them, as seen when upper rank members Daki and Hantengu were able to glimpse the memories Muzan had of Yoriichi Tsugikuni during of their fights against Tanjiro Kamado.

Telepathic Communication: Muzan has the ability to read the minds of Demons he shared his blood with when physically close to them, as seen when he reads the minds of all the Lesser Rangers that have gathered behind him. Later, it was shown that he could also send telepathic messages and have full conversations with other Demons, as seen when he communicated with Top Rank 1 Kokushibo to check how many Hashira he had defeated and ordered him to hold off the Hashira until he finished recovering from Tamayo’s poison. Muzanis also able to see what Demons see, as he did with Nakime. However, this ability is strictly limited to what is in their perception, so if a Demon’s senses are tricked, Muzan is unable to realize the difference.

Curse: Muzan also gains several advantages over those with his blood in them, such as the ability to read their minds, sense their location, and becoming able to destroy any cells in their body if he so chooses. The curse has however been broken twice by demons who do not want to eat humans and by pacifist natures.

Demon Control: Muzan can control Demons to some extent, as seen when he was able to take control of Nakime’s body to try to force an absorption of Yushiro’s cells in order to end his meddling when attempted to usurp control of Infinity Castle. However, this ability requires great concentration as Muzan immediately lost control of his body the moment he had to defend himself in the midst of battle. Other Demons can also take control back from him. Muzan can also detonate a Demon from a distance: by closing his fist, he can crush a Demon’s head from a distance.

Possession: Later, as seen in Tanjiro’s consciousness as a Demon, Muzancan actually implant a small portion of his consciousness into a Demon he creates using his blood, provided he injected gigantic amounts of his blood into them when they were created. As seen, a part of his spirit was actually still present in Tanjiro’s mind despite having been previously killed by the sunlight, and then attempted to influence, control, and possess. Tanjiro to “inherit” his will and remain as a demon. However, the difference between his power to “control” a demon and his power to “possess” it is that he can no longer take control of a demon by force and force them to do what he wants. . On the contrary, he must convince them to obey his orders, by giving his victims the possibility of resisting him and escaping from his grip.

The Art of Blood Demons

Black Blood: Bramble – Muzan uses his own flesh and blood to create multiple spiked threads to entangle his target.

Shockwave: Later, after being pushed into a corner by Tanjiro and Obanai and weakened by Tamayo’s four-stage drug, Muzan displayed another ability unique to his battle form, in which he transformed his torso and his upper body into a gigantic bestial mouth. From there, it released a powerful shockwave scream, capable of severely injuring anyone caught within its range. When Tanjiro and Obanai were caught in the blast, even Kiriya and her sisters, who were connected to them by the crows in the area, were the most affected by the attack. This technique is capable of causing convulsions, paralysis and respiratory disorders. However, it is mainly used as a defense technique, intended to ward off attackers. This technique requires a cooldown before use, and thus cannot be used consecutively, although it is widely suggested that Tamayo’s drugs further endanger his ability to use this attack. Its impact can be lessened by the use of a Nichirin blade, as self-mutilation can dispel some of its effects.

Complex Poisons/Drugs: Muzan has also shown a weakness to being inflicted by incredibly complex poisons or drugs foreign to him. As seen in Tamayo’s attempt to humanize him through drugs, he has to take time and concentrate hard to analyze the composition of a drug by transforming into a cocoon of flesh to analyze and immunize against drugs or poison. Later, upon learning the aging stage of the drug from Tamayo, Muzan realizes that his body also spends most of its strength to fend off the extreme aging effect of the drug, which leaves him with little power to use in the fight against the Hashira.

Regeneration: Even if his body were destroyed and his head completely destroyed, it wouldn’t kill him

Extrasensory Perception: Can sense the presence of demons and humans, as well as bloodlust,

Absorption: He was going to absorb Tamayo, and planned to absorb the spikes that penetrated his flesh, as well as eat Nezuko to gain his immunity to sunlight, Adapted to become immune to decapitation by blades created with metal infused with sunlight. Should be able to adapt to poisons better than other upper moon demons, who became resistant to the wisteria poison that kills normal demons in seconds, and was adapting to a poison made to turn demons into humans, Biological Manipulation / Blood Power Outpouring, Blood Manipulation, Telepathy of those he shared his blood with Teleportation and Spatial Manipulation with Fortress of Dimensional Infinity, Poison Resistance.

Immortality: Since taking medicine from Blue Spider Lily, he can live for several centuries without aging, immunity to disease.

Durability: At least better than Tanjiro. Was hit by an explosion that reduced a mostly intact house to ashes.

Notable attacks/techniques:

Shapeshifting: Muzan can control his body shape and even his presence, making him able to transform into someone completely different without even those with ESP noticing, though he doesn’t. can’t fool the smell of Kamado Tanjiro. Shapeshifting allows her to become a child, and an adult, a woman, or even grow a pillar of flesh, eyes, and a mouth to eat others, or a cocoon of flesh to expand and fit to poisons.

Demon’s Blood: His blood causes all cells in the body of those he enters the body to transform, turning them into demons. This gives them several default powers: enhanced strength and senses, top-down regeneration, eternal youth, and shapeshifting, could eventually give them additional powers. Cascading Demons gain Blood Arts, which can range from simple Wire Manipulation to Spatial Manipulation, but have several downsides: the sun reduces demons to ashes, objects imbued with the sun’s energy kill themselves they are used to decapitate the demon, wisteria flowers become deadly poison to them, and they crave human flesh. In the event of an overdose, the cells break down one by one.

Curse: Muzan also gains several advantages over those that contain his blood, such as the ability to read their minds, sense their location, and becoming able to destroy any cells in their body if he wishes. The curse has however been broken twice by demons who do not want to eat humans and by pacifist natures.

Blood techniques: Techniques obtained by the manipulation of one’s blood, their effect is very variable.

Black Blood Technique: Chain of Thorns: Essentially multiple telekinetically controlled barbed wire that wraps around the enemy to kill them.

Weaknesses: The sun turns it to ashes and only the Sun’s Breath user can defeat it. Because of this, Muzan, like other demons, could only do all his activities at night. Muzan now aims to eat Nezuko in order to gain immunity to sunlight.

The Fortress of Dimensional Infinity: A pocket dimension in which he can teleport himself and others through a maze consisting of several rooms. The pocket reality contains several demons, including upper moon members like Akaza. It’s unknown if the Fortress or Muzan himself created it, but some points are upside down.

Weaknesses

Sunlight: Muzan is known to be immune to decapitation, as seen when Gyomei destroyed his head and still managed to regrow it. So the only other known way to destroy it is through sunlight. Her attempts to locate and devour Nezuko in order to make her immune to sunlight are all the more believable.

Crimson Red Nichirin Blade: Demon Slayers who have awakened the Mark of the Demon Slayer can unlock the power to change the color of their Nichirin Blade to a brilliant crimson red. This especially applies to Demon Slayers who use the Breath of the Sun or the Hinokami Kagura. A swipe from a crimson red nichirin blade can impede the regeneration of demons and even incinerate their cells, which disables or even kills demons with high regenerative abilities. Muzan is no exception, as seen in his fight against Yoriichi Tsugikuni.
