Muzan Kibutsuji

Voiced By: Toshihiko Seki

https://static.tvtropes.org/pmwiki/pub/images/muzan_encountering_tanjirou.png
Click here to see him as a woman 

Muzan is the first demon and progenitor of all of the other demons.


  • Authority Equals Asskicking: The most powerful of the demons.
  • Bad Boss: He sucks as a boss. Even mildly contradicting him can result in an agonizing execution.
  • Badass in a Nice Suit
  • Berserk Button: He kills a random passerby for calling him sickly and pale, with the latter's companions subjected to a Cruel and Unusual Death. Granted, considering his sociopathy and Hair-Trigger Temper, he'd have probably killed them anyway.
  • Big Bad: The arch-villain of the story and the chief demon.
  • Bitch in Sheep's Clothing: As "Tsukihiko", he comes off as an impeccable gentleman and a considerate family man. He likewise plays the role of a quiet and studious young boy very well. Beneath the facade, however, is a monstrous demon who only cares about himself.
  • Body Horror: One of Muzan's unnamed Demon Blood Arts creates a large and long mass of grotesque flesh from his arm that comes with a giant mouth at the tip. The Lower Kizuki, unfortunately, get to see this up close and firsthand... And currently, he's inside a cocoon made up entirely of his flesh and blood to recover his injuries sustained from Ubuyashiki, Tamayo, and Himejima. It's not a pretty sight to see.
  • Cannibalism Superpower: Muzan is implied to gain the powers of the demons he procreates by eating them. After Nezuko gains immunity to sunlight, Muzan makes devouring her his number one priority to become truly immortal by being invulnerable to the one thing that can ultimately kill him.
  • The Corrupter: Muzan lures in people at their lowest to become demons, twisting their emotional trauma so that they serve him wholly. Gyuutarou, Daki, Akaza, and Kokushibou are prime examples of this.
  • Deal with the Devil: He's the devil here, offering people the chance to become demons, forsaking their humanity and needing to devour others, in exchange for life or power. Kokushibo is a noticeable example, who was terrified of losing his sword skills to age and death, after which Muzan stepped in with his 'offer.'
  • Didn't See That Coming: He gets spectacularly blindsided by Ubuyashiki's suicide trick, which leads to the entire Demon Slayer Corps getting the drop on him. Tamayo also blindsides him with a perfect cure for demonism which, while not successful at reverting him right away, still makes him unable to fight. and forces him to summon his Demon Fortress in a desperate escape attempt, which promptly gets besieged by the full force of the Corps.
  • Dirty Coward: Tamayo believes everything he does is out of fear of anything that could hurt him.
  • Disproportionate Retribution: It's very easy to get him to kill you. Just saying something, anything that somehow contradicts what he says, will immediately get you a violent death.
  • The Dreaded: The demon from Tanjiro's first quest is horrified when Tanjiro mentions his name. It turns out there's a good reason for this. On top of being a Bad Boss, the majority of his underlings can't talk about him without his cells in their bodies violently killing them for it.
  • Dual Age Modes: He can transform into a young boy.
  • Eerie Pale-Skinned Brunette: He's the Monster Progenitor of the demons. No matter what form he takes, he always has pale skin and jet black hair; in fact, calling him sickly and pale is his Berserk Button.
  • Establishing Character Moment:
    • When Tanjiro runs into him for the first time, he acts completely innocent. He then swiftly swipes at a man walking by him, causing the man to turn into a demon and attack his wife. This forces Tanjiro to subdue the man, while Muzan casually walks away with his own family. Later, after brutally taking his rage out on some drunken passerby who insulted his appearance. he orders two of his underlings to kill Tanjiro because his earrings reminded Muzan of another slayer who almost killed him in the past.
    • His second major appearance is another one. Angered by Rui's death, he pulls a vicious You Have Failed Me on all of the other Lower Kizuki. During which he shuts down every attempt they make to plead for another chance because it means they're implying he just might be wrong about something.
  • Evil Cannot Comprehend Good: Muzan has a difficult time understanding selfless and heroic motives, to say the very least.
  • Evil Counterpart: To Kagaya Ubuyashiki. Muzan is the lord of demons while Kagaya commands the Demon Slayers. Muzan is a powerful fighter, and possibly the strongest being alive despite being a craven, evil, and selfish coward at heart. On the flipside, Kagaya is physically weak but is an unbelievably kind, generous, and self-sacrificing man. Muzan is immortal while Kagaya is dying at age 23. Muzan cares nothing for his subordinates who serve him out of fear and fanaticism. Kagaya remembers the names, faces, and backgrounds of every demon slayer who dies, loving all of them like his own children. To top it off, the two of them are almost identical physically.
  • Exotic Eye Designs: He has twofold slit pupils, with the outer part crimson and the inner part black.
  • Genetic Memory: Those who receive his blood can experience parts of his memories.
  • Gender Bender: During a meeting after Rui's defeat, he appears in the form of a woman.
  • Hair-Trigger Temper: It doesn't take much to set Muzan off. Even mildly contradicting him can provoke his violent wrath.
  • Hellish Pupils: His eyes are red with slit pupils.
  • Interspecies Adoption: Lives with a human family masquerading as a child, though they think he's just a kid with a skin condition. After he learns of Nezuko, he butchers them.
  • It's All About Me: Muzan is horrifically self-centered in his viewpoints.
  • Jerkass: Muzan is shown to be an unpleasant bastard throughout the series. He belittles both the main characters and even some of his own demons.
  • Jerk with a Heart of Jerk: You would think his backstory reveal in chapter 127 would gain Muzan some sympathy points right? Well, that's definitely not the case. Muzan has been revealed to always have been an evil jerk for his entire life. In the past, when a doctor attempted to use an experimental medicine to cure his disease, he told Muzan that there was a possibility that he wouldn't be able to survive despite his efforts. Muzan ends up throwing a knife at the doctor out of anger.
  • Keigo: As "Tsukihiko", he speaks in formal Japanese, emphasizing his genteel and debonair demeanor.
  • Lack of Empathy: If you aren't Muzan Kibutsuji, he doesn't care remotely about your problems or your feelings.
  • Magic Pants: When caught in an explosion created by Ubuyashiki, his upper body gets utterly shredded, with his shirt being entirely disintegrated and much of his flesh being burned away revealing muscle. Yet somehow, his pants remain completely unscathed.
  • Make-Up Is Evil: When in the form of a woman, he wears heavy mascara and a small amount of lipstick. He also happens to be the first and most evil of the demons.
  • Man of Wealth and Taste: When not in the form of a woman or child, he wears Western-style formal wear in opulent patterns. He also happens to be the Big Bad and the Monster Progenitor of the demons.
  • Meaningful Name: When encountered by Tanjiro, Muzan plays the role of a genteel and debonair merchant by the name of Tsukihiko, which combines the Japanese words for "moon" and "a male child of noble blood, a prince". The "moon" part may have something to do with his demonic inability to survive in the sun.
  • Morphic Resonance: He retains his black hair, pale skin, and unusual eyes in his female guise.
  • Monster Progenitor: He is the one who created the demons, though he states that he actually hated doing it, but had to in order to find either a demon that could withstand the sun or the main component in the elixir that made him a demon in the first place.
  • Monstrous Cannibalism: Not only does he eat humans, but he is also willing to eat his own kind. He eats Kamanue and Mukago alive for being cowards and weak Lower Kizuki, not to mention his endgame with Nezuko, who has his coveted immunity to the sun, planning to eat her to get that power for himself.
  • Names to Run Away from Really Fast: Muzan means miserable, atrocity, cruelty, cold-bloodedness, tragic, pitiful, and merciless, while Kibutsuji begins with the kanji for "Oni".
  • Narcissist: He thinks that he alone is the perfect being in the world. Any contradiction to his world view is met with instant death.
  • Noodle Incident: In the past, he encountered a Demon Slayer who wore the same kind of earrings that Tanjiro does. While the encounter isn't explored (though it was apparently the closest Muzan ever came to being killed), he's paranoid enough to order Tanjiro's death upon seeing them. This may or may not have to do with the Sun Breathing technique, which is (so far) practiced by individuals wearing such earrings.
  • One Head Taller: He is about a head taller than his wife, Rei.
  • Really 700 Years Old: He's been around for about a millennium; he became a demon in the Heian Era (late 700's), and the story takes place in the Taisho Era (the early 1900s.)
  • Red Eyes, Take Warning: He has irises and outer pupils in different shades of red. He is one of the most monstrous demons.
  • Sharp-Dressed Man: He has a taste for western-style suits.
  • Telepathy: He has the ability to hear the thoughts of any demons who have his blood in them. The closer they are, the clearer he can hear them.
  • The Sociopath: He is perfectly capable of behaving in a civilized manner in order to blend in, but it's shown that he fundamentally lacks morals and sympathy completely.
  • Underestimating Badassery: He does not take any of the demon slayers seriously, viewing humans as well beneath any demon. He also underestimates the resolve of Ubuyashiki, as his self-destruction catches Muzan entirely off guard, giving Tamayo an opportunity to trap him.
  • Variable-Length Chain: One of Muzan's Black Blood Techniques is called Chain of Thorns, a Blood Art that creates thorny tendrils that sprout out of his arm. Himejima easily deflects this move with his Stone Breathing skills.
  • Vocal Dissonance: He still speaks with Toshihiko Seki's masculine voice while in his female form.
  • Waistcoat of Style
  • Would Hurt a Child: He kills not only Tanjiro and Nezuko's mother but also their young siblings.
  • You Have Outlived Your Usefulness: Pulls this on the Lower Kizuki. He also does this to The doctor that made him a demon, because he at first thought the doctor failed to cure his terminal disease - to his own detriment since only the doctor knew about the main components in the elixir.
  • You Monster!: Tanjiro calls him a true demon for deceiving his loyal followers, Susamaru and Yahaba.

Twelve Kizuki

     Tropes that apply to all of them 
  • Asskicking Equals Authority: Many of them (especially the Upper Kizuki) managed to earn their position by being powerful demons on their own right, and thus attracting Muzan's attention.
  • Authority Equals Ass Kicking: Others attained their status because Muzan directly gave them enough of his blood to become as powerful as they are, which he did because some unique detail of their human lives caught his interest.
  • Boss Bonanza: The climatic Dimensional Infinity Fortress Arc focuses on the entire Demon Slayer Corps assaulting Muzan's base of operations, which features several extremely difficult fights against the Upper Kizuki in quick succession (or simultaneously).
  • Exotic Eye Designs: All of them have their Kizuki rank on their eyeballs in the place of an iris and pupil. On top of this, they also tend to have additional unique eye features, like odd colors or strange eyelashes.
  • Dragon with an Agenda: Downplayed. Many of them have their own ambitions and plans, but these usually don't come into conflict with their loyalty to Muzan. Muzan generally grants them a considerable degree of independence as well and lets them do as they wish until he needs them for something in particular.
  • The Heavy: They collectively take this role as Muzan almost never makes a move on his own, limiting himself to giving orders.
  • Identity Amnesia: Most of the Kizuki don't recall their past lives as humans at all or beyond context-less glimpses. Muzan has exploited this to make them more manipulable.
  • Klingon Promotion: Muzan makes it clear that only the strong belong in this close circle. He has established a Blood Succession Battle system where a demon seeking to be ranked higher within the Twelve Kizuki can just rip their way upwards against upper ranks and take the seats if they are up to the task.
  • Marathon Boss: All of the Kizuki that the Demon Slayer Corps fight (with the exception of Kaigaku) are extremely difficult to bring down, requiring upwards of a dozen chapters just to fend off. And sometimes the Slayers aren't even able to kill them.
  • More Than Mind Control: Most of them are kept in place through fear and desire to attain status, but Muzan also enjoys leading them on with empty promises to manipulate them.
  • Really 700 Years Old: Most demons are regularly culled by the Corps, but Kizuki are much stronger, so they are more likely to enjoy the immortality that comes with being a demon. While the ranks of the Lower Kizuki are shuffled around with some frequency, most of them are very old. Apart from Kaigaku, all of the Upper Kizuki are at least a hundred years old. Kokushibo deserves special mention, being that he was already Upper-1 since 400 years ago, and is probably the second oldest demon, only younger than Muzan himself.
  • Sorting Algorithm of Evil: They are always fought in ascending order of rank, which also signals their power (though technically Rui, Lower-5, was fought before the Lower-6 Kyogai, having lost the position).
  • We Have Reserves: Muzan replaces the Lower Kizuki often (although he eventually gets tired of this and disbands them permanently). While the loss of an Upper Kizuki is a very significant hallmark, he isn't particularly bothered by this and has no problem making more.
Lower Kizuki

    Rui 

Rui

Voiced By: Kouki Uchiyama

https://static.tvtropes.org/pmwiki/pub/images/rui_7.jpg
The Lower-5 and a member of the Twelve Kizuki.
  • Arc Villain: Of the Mount Natagumo arc, being the leader of the Spider family and the strongest demon Tanjirou and his friends fight in that arc.
  • Animal Motif: Spiders. His hair is shaped like one; he uses threads as his main weapon (reminiscent of a spiderweb) and has three pupils in each eye, similar to how spiders possess multiple eyes. This later carries over to his "family", as each member has traits of a spider after Rui modified them to make them more similar to him.
  • Anime Hair: Rui’s hair is styled to look like a spider’s legs wrapping around his face.
  • Berserk Button: He tortures his family whenever they revert to their original demon forms.
    • Tanjiro royally pissed him off when he called his family bonds “fake”, and Rui went out of his way to make him suffer for it rather than just kill him immediately.
  • Curb-Stomp Battle: Toys with Tanjiro for a while before defeating him with ease. Tanjiro manages to recover and fight back seriously, but Rui still gets the upper hand thanks to quick thinking... And a second later Giyu shows up and delivers this himself, one-shotting Rui with a single clean move so fast that he didn't even notice
  • Deliberate Injury Gambit: Severs his own head with his threads just as Tanjiro's about to decapitate him, saving his own life.
  • Domestic Abuse: He abused his fake family when they didn't follow the roles they are given by him.
  • Evil Albino: While he had a normal complexion when he was human after he became a demon, his hair turned white, his skin became extremely pale, and he developed red sclera, giving him the image of an albino.
  • Made of Iron: His skin is even tougher than his threads, the same ones that broke Tanjiro’s Nichiren Sword.
  • Ill Boy: Rui in life was this, which was why he became a demon. His mother even apologized to Rui with her dying breath for not giving him a healthy body.
  • My God, What Have I Done?: His reaction after killing his parents, and after reuniting with them after his own death.
  • I Just Want to Be Loved: He created a false family with other demons because of his lingering emptiness from killing his real parents.
  • Offing the Offspring: Rui's father did this upon discovering Rui became a demon, because they couldn't live with their son's crimes, but did so with the intention of dying with him.
  • Razor Floss: His web threads are extremely sharp, capable of easily slicing apart human flesh and bone, and even snapping Tanjiro's Nichirin Sword.
  • Self-Made Orphan: Rui's father tried to kill him after Rui started eating humans. In response, he killed his father and mother. He only remembers as he's on the verge of death that his father had said they'd all die together.
  • Slasher Smile: Though he is usually stoic and expressionless, he shows a nasty grin when he reveals to Tanjiro his rank as Lower-5.
  • The Stoic: He only shows any expression regarding the idea of family.
  • Spiders Are Scary: Rui and his whole 'family'.
  • Together in Death: Rui reunites with his real parents in death.
  • White Hair, Black Heart: White hair, and a toxic, twisted idea of family values.
  • Villainous Breakdown: He narrowly manages to avoid Tanjiro’s killing blow, but by his own admission, Rui had never been angrier before in his life.
  • Wake-Up Call Boss: While other demons weren’t exactly easy for Tanjiro to deal with, Rui is the first demon he outright loses against. By the moment he snapped Tanjiro’s sword in half, it was clear that this wasn’t an even battle. He even managed to avoid a last-ditch move that would have killed him without quick thinking. Tanjiro would have been killed on the spot had Giyu not arrived.
  • The Worf Effect: Puts Tanjiro through the wringer and came close to killing him. Then Giyu shows up and one-shots him.
  • Would Hurt a Child: In the anime, Rui is willing to abuse his "mother", who is actually a child demon after she accidentally reverts back to her original form seen in the "older sister"'s flashback.

    Enmu 

Enmu

Voiced By: Daisuke Hirakawa

https://static.tvtropes.org/pmwiki/pub/images/kny_enmu.jpg
The Lower-1 and a member of the Twelve Kizuki.
  • Bait-and-Switch Boss: Albeit a very tough opponent on his own, he's the bait for the immensely more dangerous Akaza.
  • Body Horror: After merging with the Infinity Train, Enmu's body becomes something truly horrific, bordering on Eldritch Abomination. His humanoid form becomes a proxy that can survive decapitation by sprouting a grotesque mass of flesh to connect his head to the train, which looks like something out of The Thing. Masses of flesh with arms and eyeballs also begin forming within the train which attempt to consume passengers, and a very large spinal column forms underneath the train's engine. Once he is defeated, the true extent of his assimilation is shown, with the fleshy masses completely surrounding several cars at the front of the train.
  • Compelling Voice: One of his abilities allows him to grow a mouth on his hand which can speak and instantly put to sleep anyone who hears its voice.
  • Crazy-Prepared: Enmu is very aware of his Blood Demon Art's limitations and weaknessess, and takes many precautions to ensure the Demon Slayers on the train fall under his technique without revealing or endangering himself. Too bad he had no way to account for Nezuko's presence or Tanjiro's Heroic Willpower.
  • Dream Weaver: Has control over what the people he puts to sleep dream about, saying he likes to vary it between sweet dreams and horrible nightmares.
  • Empty Shell: Victims of his who have their spiritual cores destroyed from within their subconscious are turned into this, making them very easy to consume afterwards.
  • Evil Gloating: Upon merging with the train, Enmu drops his polite facade and begins taunting Tanjiro, confident in his victory. This leads to...
  • Explaining Your Power to the Enemy: After meeting Tanjiro and having a short fight, he explains his ability to merge with the Infinity Train and his plan to devour all passengers aboard, fully believing that he has already won at that point. This of course backfires as it gives Tanjiro the clue he needs to locate Enmu's weak spot and leads to his death.
  • Eyes Do Not Belong There: After merging his body with the train, he can grow countless eyeballs from anywhere within that can put to sleep anyone who looks into them.
  • Face Death with Dignity: While the other Lower Kizuki react with terror in the face of Muzan's purge and attempt to flee or bargain for their lives, Enmu is in ecstasy at the thought of being personally killed by Muzan and offers his life with no hesitation or fear. Averted with his actual death, where he spends his final moments cursing Tanjiro and his group while lamenting his weakness despite being given a second chance and power-boost by Muzan.
  • Faux Affably Evil: He is very well-mannered for a demon and speaks to his human subordinates with a kind and gentle tone. He also politely greets Tanjiro when they meet and continues to be cordial even as they fight. In truth, he has no respect for human life whatsoever, and only acts affable in order to manipulate the humans around him.
  • Forced Sleep: He has several techniques that allow him to do this.
  • Journey to the Center of the Mind: His Blood Demon Art allows him to enter his target's subconscious and destroy their spiritual core, which would leave them comatose. However, there are many risks to doing this, so he'd rather use human pawns to do it instead.
  • Losing Your Head: Tanjiro is able to swiftly decapitate Enmu after learning how to counter his sleep powers, but by that point he had already fused with the train and his head continues to taunt Tanjiro before melting away into the train car's roof.
  • Loves the Sound of Screaming: He greatly enjoys hearing the screams of his fellow Lower Kizuki being disposed of by Muzan.
  • Manipulative Bastard: Enmu convinces several weak-minded and emotionally vulnerable people to do his dirty work by promising them unending pleasant dreams, but he has no regard for human life and fully intends to devour them afterwards regardless.
  • Meaningful Name: His name is an anagram of nemu, meaning "to sleep" in Japanese. It can also be a euphemism meaning "to die". Fitting, for a man-eating demon that has sleep-inducing powers.
  • Multicolored Hair: He has black hair with red and blue ends.
  • Near-Villain Victory: He comes very close to accomplishing his mission of killing Tanjiro and Rengoku, at one point having both helplessly trapped within his Blood Demon Art without either even realizing that they were under attack thanks to his meticulous planning. The only reason he fails is due to Nezuko being unaffected by his technique, allowing her to briefly wake Tanjiro which gives him the chance to figure out how to counter Enmu's powers.
  • Nightmare Fetishist: Enmu enjoys the suffering of others. A lot. Especially when Muzan is the one who is carrying it out.
  • Soft-Spoken Sadist: He speaks in a soft and calm tone, but he is clearly psychotic.
  • Sentient Vehicle: Enmu merges his body with the Infinity Train.
  • Sole Survivor: Of Muzan's purge of the Lower Kizuki.
  • Sycophantic Servant: He's the only Lower Kizuki who didn't think of running away and who wasn't afraid of being killed by Muzan until he decides to give him a second chance to redeem himself by killing Tanjiro.
  • This Cannot Be!: After having his spinal column severed by Tanjiro, Enmu is in utter disbelief at what happened. He had all the present Demon Slayers, including a Hashira, under his technique and at his mercy, but still ultimately failed without even killing a single human aboard the train.
  • Too Clever by Half: Enmu is a very intelligent foe and is driven by his desire to rise up the ranks of the Upper Kizuki to prove his worth to Muzan. However, his intelligence and conviction lead to arrogance, gloating to Tanjiro once he merges with the train and inadvertently giving Tanjiro the clue he needs to locate his weak point.
  • Undying Loyalty: The other Lower Moons tried to flee or bargain for their lives, but Enmu simply offered his life and endless praise for Muzan. Muzan instead gives him a painful Deadly Upgrade and spares his life.

     Other Lower Kizuki Members 

Voiced By: Taiten Kusunoki (Rokuro / LM2), Soichiro Hoshi (Wakuraba / LM3), Kana Ueda (Mukago / LM4), KENN (Kamanue / LM6)

https://static.tvtropes.org/pmwiki/pub/images/kny_lower_moons_4.jpg
From up to down: Rokuro (LM2), Wakuraba (LM3), Mukago (LM4) and Kamanue (LM6)
Muzan Kibutsuji's six less powerful minions. Unlike the Upper Kizuki, they have been killed and replaced many times.
  • All There in the Manual: In the first fanbook, it was revealed their names were Rokuro (Lower-2), Wakuraba (Lower-3), Mukago (Lower-4), and Kamanue (Lower-6).
  • Dark Chick: Mukago was the only female of the Lower Kizuki.
  • Dirty Coward: According to Muzan, Mukago is afraid to fight the Demon Slayer Corps, and she has no intention to fight the Hashira.
  • Eaten Alive: Both Kamanue and Mukago were eaten alive by Muzan.
  • Exotic Eye Designs: The Lower Kizuki have one eye with their number engraved into it. In addition, Rui and Enmu's other eyes are also unusual; Rui's eyes have three pupils, and Enmu has a horizontal rectangular pupil.
  • Facial Markings: Like most demons.
  • Morton's Fork: After criticising their strength and questioning their worth as subordinates, Muzan gives them a chance to speak for themselves, which amounts to either agreeing or disagreeing with his assessment. Wakuraba realizes that Muzan will kill them no matter what answer they give, as he has no use for weaklings and hates those who speak against him, and decides to Take a Third Option by attempting to flee.
  • Nothing Is Scarier: While the other members' fates are shown in brutal detail, Rokuro's death is offscreen and only a pool of blood is shown afterwards. Given that he was the Lower Kizuki who had angered Muzan the most, it must not have been a pretty sight.
  • Oh, Crap!: Kamanue's reaction when he realizes that Muzan can hear the thoughts of demons.
  • Screw This, I'm Outta Here!:
    • Mukago was thinking about running away from the dimension fortress after Muzan decides to kill the remaining Lower Kizuki, but is eaten by him.
    • Wakuraba attempted to flee from the dimension fortress, but Muzan quickly decapitated him.
  • Tears of Fear: Kamanue and Mukago, moments before Muzan eats them both.
  • We Hardly Knew Ye: Muzan decides he doesn't need them. They aren't even named in the story.
  • You Have Outlived Your Usefulness: Muzan decides that the Lower Kizuki are too weak to be worth the effort of keeping them around, and kills all of them except Enmu.

Upper Kizuki

    Kokushibou 

Kokushibou Michikatsu Tsugikuni

https://static.tvtropes.org/pmwiki/pub/images/kokushibou_2_1.jpg
Upper-1. Muzan's partner and right-hand man, he has occupied the position of Upper-1 since at least 400 years ago.
  • The Ace: The top Kizuki and the scariest, as well as the most skilled.
  • Alas, Poor Villain: As he lays dying, he realizes that he ultimately wasted his entire life pursuing an inferiority complex against his brother, even though the latter never bore any grudge against him. His last thoughts are asking why he was even born.
  • All for Nothing: Selling his humanity to become the strongest and becoming a monster? He never could surpass Yoriichi and simply becomes one of the monsters that he once hunted. He realized that all of those centuries of trying to be the undefeated swordsman led to nothing beneficial for him.
  • Always Second Best: He lived his life in the shadow of his twin Yoriichi. He was never, ever able to surpass him or learn the Breath of the Sun.
  • Always Someone Better: For Kokushibo, it was his younger twin brother Yoriichi, who he could never surpass. Even as an immortal demon, and with Yoriichi an old man, Yoriichi still proved to be the superior between them.
  • Antiquated Linguistics: He was a human from at least 400 years prior to the current setting. Unsurprisingly, he speaks in extremely antiquated Japanese. How it's translated into English varies within fan translation efforts. The official Viz Media translations put a little more effort into adapting Kokushibo’s manner of speaking from time to time.
  • BFS: It turns out his regenerating katana can grow longer and sprout multiple smaller blades out of its main blade. It also counts as an Oddly Shaped Sword due to adding extra blades on its blade.
  • Big Brother Worship: Inverted. In his final moments, he remembers that all he wanted was to be like his younger twin brother, Yoriichi.
  • Body Horror: His monstrous spider-like form in chapter 176 is shown to be very disfigured. His head has all six of his eyes staring in all directions, and he grew a snout full of sharp and crooked teeth sprouting everywhere. Upon seeing his reflection on Sanemi's blade, even he is disgusted by this form.
  • Cain and Abel: Chapter 174 reveals that he is the eldest twin brother to Yoriichi Tsugikuni, the Sun Breathing user. He became jealous of Yoriichi because he was always treated as the special one, having much greater natural talent and skill than he could ever compete with. He was even astonished that his brother managed to survive with Demon Slayer Mark during their battle 400 years ago and that even at the age of 85, Yoriichi's skill and physical prowess hadn't dulled in the slightest.
  • Clipped-Wing Angel: What his spider demon form turns out to be, given it took a lot of energy for Kokushibo to No-Sell his beheading and his regeneration slowed down considerably as a result. Kokushibo’s grotesque appearance also leads to the demon having a What Have I Become? moment when he sees his reflection, giving the Demon Slayers more openings to attack.
  • Clothing Damage: He loses his haori to Himejima and Sanemi's combination attack, leaving him topless.
  • The Corrupter: Kokushibo converts Demon Slayers over to Muzan's side by overwhelming them with his power and then forcing them to drink Muzan's blood, turning them into demons themselves. He recruited Kaigaku this way and would have done the same to Muuichirou if Genya and Sanemi haven't intervened.
  • Death Glare: He gives an epic one when he wishes to make a point. When you have six eyes, it's easy to be intimidating with these.
  • Despair Event Horizon: He gave in to total despair, realizing his Mark would kill him, and he'd never be able to grow beyond Yoriichi. Muzan takes full advantage of this and easily convinces him to become the demon Kokushibo.
  • The Dragon: As Upper-1, he's pretty much Muzan's right-hand man.
  • Dying Alone: Upon death Kokushibou shamefully joins the ranks of demons who have died without anyone being there for him on the afterlife, the sign of karma from abandoning everyone that had cared for him; Kokushibou is seen being forcefully dragged into hell alone on Chapter 179's cover page.
  • Even Evil Has Loved Ones: He may be a powerful demon, but he still remembers his child very fondly and respects Muichirou as part of his family bloodline. And although he hated his brother Yoriichi, he still felt a sense of brotherly love for him.
  • Exotic Eye Designs: His rank is on two of his eyes, and all others have very prominent veins and crimson sclera.
  • Extra Eyes: He has six.
  • Eyes Do Not Belong There: He's shown to have over a dozen eyeballs on the handle of his katana. And he reveals to have even more on his katana's blade.
  • Fallen Hero: Strongly implied he was once a noble samurai who opposed Muzan. He was a Breath user turned demon because he feared the loss of all of his techniques at age 25, due to the dangerous conditions of the Demon Slayer Mark.
  • Fights Like a Normal: Despite being a demon, Kokushibo relies more on his swordsmanship and Moon Breathing techniques, rather than using the supernatural Demon Blood Arts.
  • Green-Eyed Monster: Kokushibo's driving motivation besides his fear of losing his skill to aging and death was deep envy of his twin brother Yoriichi, particularly Yoriichi's great skill and selfless devotion to others.
  • Healing Factor: Expected from being a demon, but his demonic sword also has its own regenerating factor, being able to grow back its blade even after being broken. And this regenerating factor can even make his sword grow longer and sprout multiple blades on it.
  • Heel Realization: When he looks at his own reflection in Sanemi’s sword, he realizes what a monster he's become, despite trying to retain his human appearance. He decides to die in shame of turning into such a beast.
  • Hero Killer: He takes the lives of both Muichirou and Genya.
  • I Just Want to Be Special: He reveals that his entire motivation and reason for jealousy was because he wanted to be special like his brother Yorichii was in the past.
  • Implausible Fencing Powers: His Blood Demon Art is not only the manipulation of his sword to grow or sprout additional blades but also to grow dozens of blades out from various points in his body, allowing him to use his Moon Breathing techniques with all his blades at once. Keep in mind, they're still in his body and poking out from spots like his thighs, his chest, his shoulders, etc.
  • It's All About Me: His motivation in his human days as Michikatsu was to be the best and undefeated swordsman in all of Japan. And he was willing to go great lengths in order to never to lose a battle nor his techniques, so far as to eventually becoming a demon. He also lost hope of training the disciples who could not successfully master the Breathing techniques under him and his brother Yorichii and decided to not pass down the teachings, keeping the techniques to himself. Yorichii thought differently, though. He believed that the next generation of swordsmen would one day learn their techniques and surpass both of them in the future. Michikatsu was only thinking about himself, so of course, he could not comprehend the hope Yorichii had for the next generation.
  • Intoxication Ensues: Sanemi attempts to throw off Kokushibo's game by using his rare blood to intoxicate the air. It works since Kokushibo smelled his blood and started stuttering with his footwork, but this was only temporary, as Kokushibo eventually regains his focus.
  • Katanas Are Just Better: He's the only demon out of all the Twelve Kizuki who wields a katana. This is because he used to be a Breath User.
  • Luke, I Am Your Father: Or ancestor to be exact, towards Muichirou.
  • Master Swordsman: In his fight against Muichirou, he is shown to be a very skilled and unmatched swordsman. Not only does he cut off Muichirou's hand with one slash, but he also manages to stop Muichirou's sword with just two fingers and flips his own sword against him. There's a reason why he's the top-ranked Kizuki and Muzan's most valuable ally.
  • Names to Run Away from Really Fast: Kokushibo derives his name from the Japanese word for The Black Death. He is one of the few demons who clearly remembers their past lives as human beings, including their previous name, Michikatsu Tsugikuni, so it seems he willingly took that name.
  • No-Nonsense Nemesis: Kokushibo does not screw around. When a fight starts and his sword is drawn, he aims to bring his opponent down and break them completely. The most he'll allow is for a defeated foe to become a demon themselves.
  • Not So Stoic: Kokushibo, when pressed, begins shedding his stoicism, letting loose ear-splitting roars of fury.
  • Parental Abandonment: He left behind his child when he became a demon.
  • Power Tattoo: It is all but stated in chapter 174 that the markings on his face are a Demon Slayer Mark, which increases a Demon Slayer's strength, durability, and speed to legendary heights. It also can be inferred that he became a Demon in order to prevent the Mark from killing him at age 25.
  • One-Winged Angel: His frustration at his brother's beliefs and the strength of the Demon Slayers gives him the determination to not lose, forcing himself to regenerate despite being beheaded, as well as to transform into a monstrous, spider-like form.
  • Secret Art: He doesn't use Demon Blood Arts as his primary method of fighting. He's a Breath user; specifically, Moon Breathing.
  • Sibling Yin-Yang: He and his twin brother Yoriichi. While he fears death because he's afraid that his sword techniques will be lost, his brother accepted this, believing that someday someone stronger than him will surface and surpass them. He is the user of Moon Breathing, while his brother is the user of Sun Breathing.
  • Start of Darkness: In chapter 177's flashback, Michikatsu reads his mother's will and after finding out that Yoriichi knew about their mother's sickness and had been helping her out rather than clinging to her side like he thought, his nose bleeds and he starts to feel jealously against Yoriichi because he gained their mother's affection and Yoriichi had always been talented since birth.
  • Super Mode: His fear that he might actually die against the Hashira causes him to unleash his Blood Art to his full power, which sprouts copies of his sword from numerous points over his body. This allows him to use his Moon Breathing technique with each one of the swords at once, meaning that if he hadn't been restrained and weakened by Genya's Blood Art, he would have easily killed the Hashiras that were struggling to contend with him when he had just one sword.
  • Sizeshifter: During his battle with the Hashiras, he became much more muscular and taller than before after they destroyed his haori, now standing head and shoulders above even Himejima.
  • Sword Beam: He can create large beams from his sword when his sword enlarges. It greatly increases his range and puts Himejima and Sanemi on the defense.
  • The Coats Are Off: He already seemed to be too much trouble with his clothes fully on. Kokushibo was making three Hashiras (Muichirou, Himejima, and Sanemi) break a sweat against him. Then, Himejima and Sanemi manage to rip Kokushibo's haori (coat) off, and that's where Kokushibo stops playing around. Himejima and Sanemi went from trying to go on the offensive to then struggling just to not die against Kokushibo's devastating long-range attacks.
  • The Stoic: Nothing phases him at all. Not death threats from a subordinate, not Muzan contemplating exterminating the Kizuki, not a death battle.
  • Tragic Keepsake: As a child, he gave his younger brother a crude wooden flute that Yoriichi came to cherish as his most precious possession. After they have their final duel and Yoriichi passes on, Kokushibo finds that Yoriichi had kept the flute on his body all that time despite knowing his brother had forsaken his humanity and become a demon, something which deeply moves Kokushibo and brings him to tears. After his death at the hands of Gyomei and Sanemi, it is revealed that Kokushibo kept the flute on his body as Yoriichi had, the last remnant of his humanity that he could not let go of.
  • Undying Loyalty: Kokushibo serves Muzan as a samurai would serve his chosen lord.
  • Used to Be a Sweet Kid: Downplayed in chapter 177's flashback. When he was Michikatsu in his youth, he wasn't really outgoing, but he was not bad either. This was due to how he was raised by his father, who was a strict man. One of the kind gestures that he had done as a child was given his little brother Yoriichi a small flute he made himself, but it was because he pitied Yoriichi. He also talked with Yoriichi more often, but it was just to get some answers about Yoriichi's special talent.
  • Villainous Breakdown: Not as much as most other examples, but as the slayers start gaining ground on him and getting closer to victory, he starts panicking and loses his composure.
  • Villain Respect: After discovering that Muichirou is his direct descendant and analyzing his fighting skills, he gives him great respect and even offers him to become a demon and join Muzan's army if Muzan allows it. But he gives the greatest respect to Himejima, who he claims is the strongest Hashira he has fought in over 300 years, and attempts multiple times to persuade Himeajima to become a Demon so that he can preserve his techniques since the Demon Slayer Mark will kill him by the end of the night.
  • What Have I Become?: Seeing his spider demon form reflected in Sanemi's sword makes him realize how much of a monster he has become in trying to be as strong as his talented brother. Understanding how much shame he has lived with through his life just because he couldn't stand losing to his brother causes his regeneration to give out to the wounds of the Hashiras' new Red Nichirin blades, making his body crumble and allowing Sanemi and Himejima to smash him to bits.
  • X-Ray Vision: His six eyes allow him to see through his opponent, being able to examine their inner body structures and such.
  • You Remind Me of X: Upon encountering Muichirou, he tells him that he seems quite familiar. Muichirou is his descendant, meaning that he is his direct ancestor.

    Doma 

Doma

https://static.tvtropes.org/pmwiki/pub/images/douma.jpg
Upper-2, formerly the Upper-6 long ago.
  • Adaptation Dye-Job: The few times Gotouge has shown Doma in color he was given white hair, the Official Digital Color release, on the other hand, gives Doma light brown hair.
  • An Ice Person: Doma's blood magic takes the form of creating icy flowers and using the cold to his advantage.
  • Berserk Button: The only thing that gets a rise out of Doma is someone mocking him for his lack of true emotions.
  • Big Eater: A dark example. Doma loves to eat human beings, especially women and devours them in large numbers, which is why he's so powerful. Shinobu exploited this so he would eat her, consuming a huge dose of wisteria poison in her body in the process.
  • But for Me, It Was Tuesday: Initially, he can't remember fighting and killing Shinobu's sister, though her being a Pillar jogs his memory soon enough. It takes even longer for Doma to remember Inosuke's mother.
  • Condescending Compassion: Views his followers that he's trying to "help" as a bunch of pitiful morons.
  • Combat Hand Fan: He fights with razor-sharp metal fans.
  • Creepy Child: His thought after his mother stabbed his father to death and committed suicide herself? "Please don't dirty this room" with an annoyed expression.
  • Cult: Doma is a cult leader, the founder of the Eternal Paradise, which believes in 'eternal happiness.' He usually achieves this by murdering and devouring people to 'relieve their suffering.'
  • Dissonant Serenity: Doma rarely acts anything but relaxed and serene to highlight how disturbing he is. Even as a human, when his mother violently murdered his father before killing herself, his only priority was airing the room out. This is up to the point where he doesn't feel anything when dying.
  • Exotic Eye Designs: Doma has numbered irises. Otherwise, though, he has the most normal-looking eyes of the Upper Kizuki. Oddly enough, as a human, he had rainbow-colored eyes.
  • Face of an Angel, Mind of a Demon: The prettiest of the Upper Kizuki, pleasant looking and all angelic smiles. Then he casually mentions keeping a girl's severed head in a pot for decoration and is a remorseless murderer who glories in his demon nature.
  • Faux Affably Evil: Acts bizarrely pleasant and friendly to everyone, which enrages Akaza. However, it's clear that it's simply an act, which causes him to come across as condescending and insincere, rather than friendly.
  • Flat-Earth Atheist: Doma believes that there is nothing after death, and when one dies, they simply 'return to the ground,' believing religion to be a waste of time. Given he's an immortal, centuries-old demon, this is quite noticeable.
  • The Gadfly: Provokes Akaza with ease.
  • Irony: After the wisteria poison in Shinobu's body kicks in and he's left severely weakened, one of his last-ditch efforts to repel Kanao and Inosuke is to summon a huge Bodhisattva statue. This is despite him being an atheist who doesn't believe in an afterlife.
  • Keet: Doma is shockingly cheerful, outgoing, and bouncy.
  • Logical Weakness: Taking a huge dosage of wisteria poison from the inside will have heavy effects on even Upper Kizuki, as Doma discovers the hard way once the poison starts to work.
  • Magic Knight: While most Kizuki are either magically or physically oriented, Doma uses a combination of ice magic and high speed to fight.
  • Monster Misogyny: Doma's preferred prey? Women.
  • Multicolored Hair: An especially odd example; it looks like light hair with a blood-red stain on top.
  • No Sense of Personal Space: Greets Akaza with a hand on his shoulder and leaves it there until Akaza tries to punch him out.
  • O.O.C. Is Serious Business: When Kanao calls him out for his lack of true emotion, Doma drops all his smiles and gets ice cold.
  • Perpetual Smiler: It's rare Doma lacks a playful smile.
  • Pet the Dog: Doma seemed as fond of Inosuke's mother Kotoha as he could possibly be of a human being, stating he enjoyed her purity and enthusiasm, intending to keep her at his side until she died of natural causes. While he did eventually murder her when she discovered him snacking on his followers, he did try to 'explain' himself first. For someone like Doma, this is an insane level of attempted benevolence.
  • Rank Up: Doma is one of the few demons who is ever given background with the Blood Succession Battle system, he once was the Upper-6 when scouting Gyuutarou approximately a century ago, later Daki and Gyuutarou become the Upper-6 while Doma went on to become the Upper-2.
  • The Sociopath: Confirmed in Chapter 158. Kanao calls Doma out for all his attempts at emotion being farcical. Doma feels no emotions and can't feel them to where Kanae states she would feel sorry for him if she did not hate him so much. He's so detached that even while beheaded and dying, he doesn't really feel anything and doesn't mind
  • This Cannot Be!: After getting his head cut off by Kanao with Inosuke's help, Doma is in disbelief that he lost to Shinobu, Inosuke, and Kanao. His thoughts told him to try and regenerate just like Muzan and Akaza did, but thanks to Shinobu's poison, he realizes that his efforts to regenerate were pointless since the overdose of poison had broken down his entire body. Becomes a Graceful Loser after realizing this fact and seeing Shinobu's spirit.
  • Tareme Eyes: They make him look more laid back than the comparatively uptight Akaza.
  • Villainous Breakdown: Averted hard. He certainly tries to pretend to have one, but he cannot bring himself to care. If anything, he seems disappointed that he cannot care at all about how he is dying.
  • Villainous Crush: As he's dying, he begins feeling emotion for the first time, which is him crushing like mad for Shinobu, even asking her to come to hell with him. She, of course, rejects him with a smile on her face.
  • Villainous Friendship: Subverted. Doma treats the other Upper Kizuki like his best buddies, especially Akaza, even bursting into tears when Akaza dies. Kanao, however, notes that this is fake, and Doma is devoid of all emotion. He can't consider them his friends because he can't even feel friendship.
  • Wise Beyond Their Years: Deconstructed. As a child, his parents created a religion with him as the leader because of his unique eyes and hair. Because of his disbelief in Gods, he looks down on them and his followers, only played along out of pity.
  • You Killed My Father: Doma killed and ate Inosuke's mother Kotoha when Inosuke was just a baby after she found he was eating his followers.

    Akaza 

Akaza

https://static.tvtropes.org/pmwiki/pub/images/akaza.jpg
Upper-3. He has been part of the Twelve Kizuki since its very first formation.
  • Achilles' Heel: Akaza's martial arts center around reading the killing intent of his opponents. When you erase that, he's far less effective. Tanjiro makes use of this by making his fighting spirit undetectable, thus giving him the upper hand in their battle.
  • Affably Evil: He's genuinely impressed by Rengoku's strength and really does want him to agree to become a demon (and perhaps even his Friendly Enemy).
  • Alas, Poor Villain: One of the most poignant in the series, Akaza flashes back to how he lost his father, his teacher, and his love Koyuki when he was preyed upon by Muzan at his lowest. With the help of their souls, he overcomes Muzan and becomes Hakuji, weeping with guilt at having failed to protect Koyuki, who weepingly tells him "welcome home, my love," just as he forces himself to stop regenerating and disintegrates.
  • Bait-and-Switch Boss: He is the switch in to Enmu's bait, showing up at the tail ending of the Train arc just as the heroes begin to celebrate.
  • Bare-Fisted Monk: Akaza is a martial artist who attacks with strong, barehanded blows.
  • Broken Tears: His spirit as Hakuji breaks down in tears and asks for forgiveness from his lover Koyuki.
  • Crippling Overspecialisation: While his ability to sense the killing intent of attacks normally allows him to perfectly predict where any blow is coming from, once Tanjiro develops the ability to eliminate his own killing intent he is completely unable to react to Tanjiro's attack even after Tanjiro loudly declares that he's about to decapitate Akaza.
  • Damn You, Muscle Memory!: His Destructive Compass simply pushes his body in the direction to both defend and attack, depending on the opponents fighting style.
  • Dark and Troubled Past: He was once a young fighter named Hakuji, who stole in order to get his sick father's medicine. Then his father hanged himself while wishing for his son to live a virtuous life instead of continuing to steal for him. And then he was taken in by a kind martial artist by the name of Keizo and fell in love with Keizo's daughter, Koyuki. After a few years of happiness together, Keizo and Koyuki were murdered by a rival dojo, while Hakuji was out of town. Hakuji killed all of the members of the rival dojo, in a single night, and then encountered Muzan.
  • The Dark Side Will Make You Forget: Becoming a demon made Akaza slowly lose his memories of his humanity, his father, his beloved teacher and his fiancee Koyuki. All that remained was the savage need to get stronger and fight more. It takes Tanjiro punching him in the face after he beheads him before Akaza realizes what monster he's become and finally accepts his loss.
    "There was nothing left that I wanted to protect."
  • Death Seeker: It's implied Akaza felt this way deep down after the deaths of Keizo and Koyuki, not wanting to live in a world without the ones he loved, but becoming a demon almost made him completely forget this.
  • Despair Event Horizon: He was already beginning to reach it when his ill father hung himself over his stealing. Then the death of his goodhearted mentor Keizo, and Keizo's daughter Koyuki, Akaza's fiancee, sent him over the edge. With nothing left to protect, he succumbed to Muzan and became one of the first Kizuki.
  • Determinator: Akaza is devoted to fighting and winning. Even when decapitated, he instantly tries to seize and hold his head in place to heal, and when this fails, his body, animated by his fighting spirit, continues to fight on autopilot. But once he finally acknowledges his loss to Tanjiro, he attacks himself and wills his body to not regenerate.
  • Driven to Suicide: Akaza realizes the one he hated and wanted to kill most is himself. The one who sullied his master's beloved Soryu style and couldn't protect the ones he loved. After destroying his own body, with help from Koyuki's soul, he forces himself to stop regenerating and dies at peace.
  • Dying as Yourself: As he dies, 'Akaza', the demon who served Muzan is gone, and he becomes Hakuji, the boy who loved his father, master, and Koyuki once more. He goes to hell with Koyuki willingly following him.
  • Even Evil Has Standards: Doma reveals Akaza would refuse to eat or even kill women despite how they would have made him far stronger. It is heavily implied that limiting himself like that is one of the key factors that led Doma and Kokushibo to outrank and overpower him.
  • Even Evil Has Loved Ones: He used to live with his father, master, and lover and cared very much for their well being in the past. He trained in his master's martial arts and made a vow to himself to protect them. And it was their spirits that brought him back to his original self.
  • Exotic Eye Designs: His number is carved into his irises, and his sclerae appear bloodshot or cracked. Additionally, he has an odd kind of fluffy eyelashes that surround his eyes completely.
  • Facial Markings: Stripes. They're on the rest of his body, too.
  • Fantastic Racism: Believes that humans are inferior to demons because they will grow old and die. He wants to "save" strong humans like Rengoku from this fate by offering them the opportunity to become demons. In the end, he remembers the actual weak humans he hated were those like the member of the rival dojo, who poisoned his fiance and mentor because they couldn't defeat either him or Hakuji in a fair fight, and himself, who forgot his father's last wish and sullied his beloved mentor's fighting style with blood.
  • Final Boss Preview: First appears at the ending of the Train arc, providing a brief, but extremely difficult fight and even claims Rengoku's life, but the actual climactic showdown with him doesn't actually take place until the Infinity Fortress arc.
  • First-Name Basis: Goes straight to using Rengoku's given name, Kyoujurou, during their confrontation.
  • Foreshadowing: Many of his lines to Rengoku about his view of human weakness and his anger at Rengoku's refusal to become a demon are big hints towards his past and heartbreaking obsession to become stronger
  • Hate Sink: In his first appearance, he rants about how pathetic humans are and laughs in the face of Rengoku for refusing to become a demon, and to top it off he kills Rengoku, who is one of the most upbeat, kind and likable characters in the series... and then when the final confrontation with Akaza comes this gets spectacularly turned on its head by revealing his extremely tragic past, which is so heartbreaking it stands out in the middle of a group of very tragic characters.
  • Healing Factor: He shows the best one of all the Kizuki so far, with him regrowing entire limbs pretty much the same second after they are cut. Justified in that his fighting style requires for his body to be intact since he makes no use of weapons.
  • Hero Killer: Ends up killing Rengoku.
  • I'll Kill You!: Directed at Kokushibou, who just wishes him luck.
  • Ironic Name: Hakuji, his original name, derives from the same kanji as the komainu, statues of lion-dog guardian deities who ward off evil spirits. The tragedy of his situation is from him being unable to protect anyone he loved and becoming a demon as a consequence.
  • Irony:
    • Throughout his appearances, he's been attempting to get stronger than Kokushibou and Doma. When he finally has the opportunity to become stronger than them, he obtains his life memories and remembers he wanted to be stronger to protect the people he loved, but they are long dead. As he's embraced by the spirits of his father, teacher, and fiancee, he willingly discards the opportunity and peacefully passes away.
    • His Start of Darkness began when a dojo of samurai poisoned his mentor and fiance to death over the fact they couldn't beat him or Keizou in a straight fight to claim Keizou's dojo. What finally gets Akaza to accept his loss and pass on in peace is being punched in the face by Tanjirou, a sword wielder.
  • Knight of Cerebus: He is the first Upper Kizuki that appeared and since then more Upper Kizuki showed up, and the named Demon Slayers started dropping like flies one by one.
  • Lightning Bruiser: Even for the Upper Kizuki, Akaza is insanely fast, and his fighting style revolves around dealing out monstrous blows.
  • The Resenter: Badly loathes Doma and Kokushibou for being stronger than him, even if he became a demon before Doma did.
  • Roaring Rampage of Revenge: As a human when his mentor and beloved died, Akaza slaughtered the dojo who murdered them with his bare hands, only sparing a single maid who went mad. The carnage was so brutal; the written account was regarded as fictitious.
  • Shadow Archetype: Akaza is quite similar to Giyuu in terms of backstory, with both being burdened by their past failures to protect people dear to them. Except Akaza is Giyuu without someone like Tanjiro to snap him out of his guilt-ridden mindset, which leads him past Despair Event Horizon and into Muzen's influence.
  • Tragic Villain: Probably the worst example in the entire series, which is already full of very Tragic Villains. Like so many demons, Muzan preyed upon him at his lowest point when he was just broken. Akaza slowly forgot his love for his father, his mentor and his fiancee Koyuki until all that remained was the thrill of fighting and the hunger for strength.
  • Tsurime Eyes: Not the only character in the manga to have them, but his are especially distinct.
  • Used to Be a Sweet Kid: Akaza was once a boy named Hakuji who loved his sick father, and eventually dearly loved his mentor Keizo and Keizo's daughter Koyuki. Then they were poisoned, and Hakuji succumbed to his rage and despair...which is where Muzan found him.
  • Villain Respect: Akaza has genuine respect for Rengoku's skills and wishes him to become a demon to get stronger alongside Akaza. Even when he has his fist sticking through Rengoku's chest, he's practically begging Rengoku to become a demon like him, so he won't die. He later admits he was wrong about Tanjiro being weak and offers him respect as well, saying the same to Giyuu Tomioka.
  • Wake-Up Call Boss: The Kizuki to this point had been tough, but beatable and the Hashira could easily bring them down, as seen by Tomioka delivering a Curbstomp Battle to Rui. But Akaza is a monster and even if Rengoku is able to do impressively well, he has no true chance in a straight fight, his death demonstrating exactly how the Upper Kizuki are no joke.
  • Walking Shirtless Scene: Akaza tends to wear very little on his upper body.
  • Walking Spoiler: More so than all the others Kizuki, as evidenced by how censored his entry is here. It is very difficult to talk about him at all, as the context of his very first appearance is a spoiler on itself, and one of the first things he does is killing Rengoku. On top of this, the details of his character and motivations are themselves enormous spoilers.
  • Worthy Opponent:
    • He considers Kyoujuro Rengoku to be this, wanting him to become a demon to preserve his amazing skill and so they can fight forever.
    • After meeting again, he believes Tanjiro is a worthy adversary, as well. He also extends this to Giyuu, inviting him to become a demon during their battle.
  • Wouldn't Hit a Girl: According to Doma, Akaza would not eat or kill women, something he found strange.
  • Wound Licking: Gloats over his closing wounds by licking them
  • You Gotta Have Blue Hair: His hair is bright pink.

    Hantengu 

Hantengu

Upper-4.
  • Arc Villain: Of the Swordsmith Village Arc, along with Gyokko, due to assaulting the village in order to cripple the Demon Hunters.
  • An Arm and a Leg: Genya rips off his two arms.
  • Asteroids Monster: Killing his emotion self just makes it split into two different emotions, and splitting them again just creates two more each, and so, each one turning more and weaker. That is unless they start cannibalizing each other.
  • Blow You Away: One of his emotions can create powerful wind blows with his fan.
  • Cannibalism Superpower: By having an emotion eat the other, they turn into a different, stronger emotion. Notable in that the emotions being devoured don't react nicely to the process.
  • Climax Boss: He's the last opponent faced before Nezuko becomes invulnerable to the sun, and after the Pillar Training Arc, Muzan comes down on them, Kagaya sacrifices himself, and the Dimensional Infinity Fortress Arc then happens.
  • Dirty Coward: Spends most of his fights whining and crying in terror while his 'emotions' do the fighting.
  • Evil Old Folks: Not that the young-looking Upper Kizuki are any younger, but he is the only one who takes the shape of a shriveled old man.
  • Four-Temperament Ensemble: After Hantengu is cut down two times, he divides between anger, joy, relaxation, and sadness.
  • Green Thumb: His Hate emotion can control trees.
  • Hypocrite: Calls human monsters for attacking him, never mind that he attacked first and that he has eaten countless humans. This attitude greatly enrages the usually kind and sympathetic Tanjiro, to where he's more than happy to behead him.
  • The Power of Hate: His strongest emotion is Hate, which takes the form of a teenaged version of himself.
  • 13 Is Unlucky: Believes that the fact that it has been 113 years since the last time all of the Upper Kizuki were called to meet with Muzan is a bad omen.
  • Literal Split Personality: Splits into multiple versions of himself when cut, each having a different attitude.
  • Magic Staff: One of his emotions uses one, capable of sending shockwaves of stunning electricity.
  • Miniature Senior Citizens: A really small, disturbingly creepy old man. While using his powers, he becomes as small as an insect, while his emotion selves become fairly big.
  • Moral Myopia: He winges and cries about being 'bullied' when he's attacked. Never mind that Hantengu, as a human being, was a recognized thief and killer, and has also eaten hundreds of people as a demon.
  • Never My Fault: Pretty much his personality and the source of his power. As a human, he used to kill and steal yet preached his own innocence, claiming his hands were acting on his own. This dissociative disorder is what apparently turned his blood art into the emotions tengu generating thing it is. The magistrate in his flashbacks and Tanjiro have no absolutely no sympathy for him in the slightest.
  • Politically Incorrect Villain: Of a sort. He steals from blind people and calls Kanroji a "harlot".
  • Obfuscating Disability: As a human, Hantengu was a thief and a murderer who pretended to be blind to take advantage of others and avoid suspicion.
  • Powers Do the Fighting: The real Hantengu just runs away and cowers in fear during the battles. His emotions, however...
  • Stealth Expert: He introduces himself into the fight by casually opening the door and crawling in the same room Tanjiro and Muichirou are in, neither of them had noticed his presence until right then. This level of skill is what makes them instantly realize they are against an Upper Kizuki.
  • Shock and Awe: His Anger emotion can send shocks of lightning through the floor, stunning and incapacitating foes.
  • Small Role, Big Impact: His battle in the swordsmith village leads to Nezuko gaining resistance to the sun. Muzan, finding out about Nezuko's new ability, compliments Hantengu as a result despite losing the battle. Thus, leading to the Dimensional Infinity Fortress battle where he infiltrates the Demon Slayers headquarters in search of Nezuko to absorb her as part of his plan.

    Gyokko 

Gyokko

Upper-5.
  • Arc Villain: Of the Swordsmith Village Arc, along with Hantengu, due to assaulting the village in order to cripple the Demon Hunters.
  • Attention Whore: Clearly the case. More than the people who try to murder him, its the blacksmith not paying any attention to him what makes him angry, and he is later baffled at how Muichiro doesn't seem impressed towards him.
  • Berserk Button: Having his pots insulted puts him into a frenzy.
  • Combat Tentacles: He can summon octopus tentacles from his pots to battle.
  • Curb-Stomp Battle: Despite transforming, an awakened Muichiro makes quick work of him.
  • Exotic Eye Designs: In addition to being in the wrong place, his eyes have his number carved into the irises.
  • Eyes Do Not Belong There: He has mouths where his eyes should be and an eye where his mouth should be and another on his forehead. One of his mouths says positive things and the other negative.
  • The Fighting Narcissist: Very much. He is constantly praising himself during fights, and it's more concerned about his enemies appreciating his "beauty" and skills than on killing them.
  • Honor Before Reason: His obsession over his art being appreciated leads him to not just kill his opponents when he could easily do so, and Muichiro's lack of reaction to him causes Gyokko to become enraged, leading to him vastly underestimating Muichiro's awakened state.
  • Mad Artist: Slaughters multiple innocents and fuses their bodies into twisted sculptures for 'art.'
  • Making a Splash: His Demon Blood Art allows him to control water and water-related creatures.
  • Multiarmed And Dangerous: Sort of. While he has several arms, both on his torso and face, they are all baby-sized at best.
  • One-Winged Angel: Can shed his skin and turn into a bigger, sea-dragon like version of himself, which he says no one has survived against. Muichirou is unimpressed, however.
  • Summon Magic: His Blood Art allows him to summon sea creatures, like piranhas or octopus, to help him fight.
  • Villainous Breakdown: Really loses it once he loses against Muichirou, ranting about how he is a supreme being, a chosen one, and how he doesn't deserve to lose.
  • Why Don't You Just Shoot Him?: Gyokko succeeds in capturing Muichirou in a vulnerable state where he cannot escape...but he ends up just leaving him alone to investigate Haganezuka refining the sword instead of finishing him off.

    Daki and Gyuutarou 

Daki and Gyuutarou

Upper-6.
  • Alas, Poor Villain: Gyutaro's death is curiously somber, reflecting upon how he wanted to protect his baby sister, his painful life and accepting hell for his sins. Daki, who became a demon at age thirteen and being far more innocent of their sins, refuses to leave him alone, rejecting heaven itself to follow him into hell. Even Tanjiro feels a measure of sympathy for them.
  • Animal Motifs: Gyuutarou is compared several times to a praying mantis, with his emaciated figure and sickles resembling the body of the insect.
  • Arc Villain: Of the Red Light District Arc, for being an Upper Moon and the one responsible for the disappearances of its women and Sound Pillar Uzui's wives.
  • Big Brother Instinct: Though they argue, Gyuutarou wants to protect his little sister.
  • Bloody Murder: Gyuutarou can weaponize his blood, using it to create slicing blades or vortexes capable of shredding his opponents.
  • Brother-Sister Team: Both Daki and her older brother Gyuutarou have the position of Upper-6.
  • Clothing Appendage: Daki's body seems to be made of prehensile fabric.
  • Children Are Innocent: After their defeat, it's strongly hinted that if she had chosen not to join her brother, the thirteen-year-old Daki would have been allowed to go to heaven. It also helped that she is one of the few demons not to have chosen to become one, having been near death when Gyuutarou made the decision for both of them.
  • Dual Wielding: Gyuutarou wields a pair of sickles made from his own flesh that are coated in poison. It is revealed in his flashback that he was proficient with the weapons since a young age.
  • Even Evil Has Loved Ones: They love one another dearly, even if they viciously bicker and insult one another. When the chips are down, all they have is one another.
  • Facial Markings: Daki has a flower-like pattern on her cheek. Gyuutarou has mottled patterns on his face and other body parts, though it is more likely that those are birthmarks since he had them as a human too.
  • Foil: Daki and her brother is this to Tanjiro and Nezuko. They are both pairs of siblings fighting and caring deeply for each other. But while Tanjro and Nezuko, at least back when she was human, can live independent from each other and think about other people, Daki and Gyuutarou only care about each other. In a more detailed contrast, Tanjirou is a caring, gentle, and honest young man with a good looking face while Gyuutarou is an ugly, violent loan shark who hurt people. Meanwhile, Nezuko used to be, and somewhat still is, a nice and mature girl while Daki is a selfish womanchild who only thinks about herself and her brother. Finally, in extreme situations, Tanjirou would (reluctantly) abandon Nezuko to fulfill his duty as a demon hunter while Gyuutarou will only have his sister as his sole priority.
  • Green-Eyed Monster: Due to his poor upbringing, Gyuutarou is very envious of those he perceives as being more privileged than him. After meeting Tengen, he sarcastically compliments him on his good looks, large physique and popularity with women before declaring that he will give him a tortuous death for being born with everything that he never had as a human.
  • Heel Realization: In his final moments before death, Gyuutarou finally remembers their past back when they were living a terrible childhood in a Red Light District, in the poorest area, under a prostitute mother who abused he and his sister to no end. He realizes that once their mother died, he and his sister Ume / Daki should have struggled more just to run away from all of that life; what Gyuutarou did instead was basically become a pimp to his own sister and teach her that she shouldn’t take crap from anybody. This indirectly pushed her to stab in the eye a samurai who wanted to have his way with her against her will, causing Daki to be burnt alive as retaliation. Gyuutarou, in his desperation, to save her, accepting the offer to become demons. Now at the brink of their death, Gyuutarou wished he taught his sister better instead of letting her be a prostitute when she could have better things in life.
  • High-Class Call Girl: Daki's human alter ego Warabihime is an oiran, a type of Japanese courtesan.
  • Homing Projectile: One of Gyuutarou's techniques allows him to manifest his blood as sickle blades that move independently and can track an enemy's movements.
  • Hypocrite: After getting beheaded and calling upon her older brother to help, Daki whines to Gyuutarou that the Demon Slayers had been bullying her. This coming from the woman who had mercilessly bullied those she viewed as beneath her, along with kidnapping and devouring any women who she felt could challenge her beauty.
  • Kill It with Fire: Daki was burned alive by john after poking his eye out and likely would have died had she not been turned into a demon.
  • Losing Your Head: Daki is beheaded but to the surprise of everyone around, she doesn't die. That's because Daki cannot die unless both she and her brother are beheaded together.
  • Meaningful Name: Gyuutarou's name comes from a word meaning prostitutes' manager.
  • Moral Myopia: Gyuutarou freely admits he cares nothing for other people's little sisters, even if he cares for his own.
  • Ms. Fanservice: Daki is the most gratuitous example of this in the series, thanks to her skimpy outfit. Countless panels with her feature examples of Absolute Cleavage, Male Gaze and She's Got Legs.
  • Prehensile Hair: Daki can manipulate her hair to attack or bind enemies, though this is much weaker than her sashes.
  • Poisoned Weapons: Gyuutarou's sickles are coated in a deadly poison, allowing him to ensure death against most opponents with a single landed attack.
  • Power Dyes Your Hair: Bleaches it white, in Daki's case. Turns out it was her original hair color, though.
  • Psychopathic Man Child: Womanchild, but Daki is extremely immature and childish which makes sense as she was turned into a demon at age 13.
  • Raven Hair, Ivory Skin: Daki is quite pale. Gyuutarou's skin is an inhumanly white color.
  • Rapunzel Hair: Daki's hair reaches past her knees.
  • "The Reason You Suck" Speech: Gyuutarou gives a brutal one to Tanjiro, explaining how his weakness prevents him from protecting what is precious to him. This speech in particular comes from the heart, as he sees Tanjiro's struggle to protect Nezuko as a reflection of his own failure to protect his younger sister Daki when they were both human.
  • The Smurfette Principle: The only female Kizuki so far but shares her position with her brother Gyuutarou, who is the far more dangerous and skilled of the two.
  • Sore Loser: After getting beheaded by Tengen, Daki throws a huge tantrum which leaves the Hashira in disbelief, ultimately calling on her brother to emerge and kill the people that had hurt her.
  • Stripperiffic: Daki's demonic outfit is equal parts lingerie and kimono.
  • Tainted Veins: When things get serious.
  • Taking You with Me: After getting beheaded by Tanjiro, Gyuutarou's headless body unleashes several large vortexes of blood in a final attempt to kill him and Tengen. They miss their targets but still destroy all the surrounding buildings.
  • Together in Death: Upon dying, they enter hell together. But not before arguing about it first.
  • Tragic Monster: A 13-year-girl who was burned alive for resisting an attempted rapist. Her big brother Gyuutaro made the choice to accept Doma's offer to turn both into demons to save her.
  • Two Beings, One Body: Gyuutarou spends his time inside Daki's body until she calls for his help. Neither of them can be killed unless both have been beheaded.

    Nakime 

Nakime

The new Upper-4 given after Hantengu's defeat. She controls the Dimensional Infinity Fortress, a dimensional fortress that Muzan and his demon army reside in.
  • Blinding Bangs: She has bangs long enough to cover her one eye.
  • Cyclops: She is a demon that only has one eye on her head.
  • Eerie Pale-Skinned Brunette: She's a one-eyed demon with black hair and pure white skin.
  • Emotionless Girl: Nakime is calm and quiet, not flinching even once when fighting against Mitsuri and Iguro.
  • Mook Maker: She can create miniature eyeballs to scout and spy around an area. This is how the Muzan was able to find the headquarters of the Demon Slayers in search of Nezuko, who can walk in the sun currently.
  • Musical Assassin: She wields a biwa, and it can manipulate and shift the environment of the Dimensional Infinity Fortress to her advantage, similar to how the Lower Kizuki Drum Demon, Kyogai, could manipulate his house domain through small drums. However, she is even more powerful as she is able to create objects such as doors and windows out of thin air to defend herself and can create large protruding pillars for offense, all with the stroke of her biwa.
  • Non-Action Girl: So far, she doesn't seem to have any physical capabilities and mostly relies on her biwa and demon magic, all while remaining in a calm sitting posture.
  • Not-So-Harmless Villain: She may not look like she can do much on her own and seems to be more of a supporting member in Muzan's army, but keep in mind that when entering into the Dimensional Infinity Fortress, she has full control of its entire environment. That means that she can simply stroke her biwa to open up a dimensional portal to keep her opponents away from her. Iguro comments on how irritating their battle will be. And keep in mind that her scouting ability is what led to the Dimensional Infinity Fortress fight while looking for Nezuko's location.
  • Portal Door: With her demon powers having full control of the Dimensional Infinity Fortress, she is able to create portals through dimensional windows. When Mitsuri attempts to cut Nakime, she just opens a dimensional window at the end of Mitsuri's jump to teleport her off of her platform. Mitsuri falls down in a comical manner before managing to grasp onto a ledge. Nakime then uses another dimensional window to teleport Iguro off of her platform.

    Kaigaku 

Kaigaku

Voiced by: Yoshimasa Hosoya

https://static.tvtropes.org/pmwiki/pub/images/kaigaku.jpg
The new Upper-6, a former rival of Zenitsu's Given the position after the death of Gyuutaro and Daki.
  • A Pupil of Mine, Until He Turned to Evil: A former student of Zenitsu's mentor, who joined Muzan out of a hunger for power and a fear of death.
  • Big Brother Bully: Zenitsu viewed Kaigaku as a big brother figure and always looked up to him, but Kaigaku clearly didn't act the part towards Zenitsu, always insulting him and never understanding all the good Zenitsu was doing for him.
  • The Bully: An unpleasant, mocking, secretly insecure jerk who pushes around weaker people, especially Zenitsu, just because he can.
  • Death by Irony: Kaigaku was a pupil of Thunder Breathing that could use all but the first form (the basis of them all), resulting in his techniques being weaker by consequence. The invented Seventh Form by Zenitsu, who could only use the first form, is a faster and more powerful version of the first form and successfully beheads him.
  • Didn't See That Coming: He had no idea Zenitsu created a Seventh Form to the Thunder Breathing...specifically to one day fight at Kaigaku's side as an equal.
  • Dirty Coward: He chose to become a demon to avoid death. And it hinted that Kaigaku was the child who sold out Himejima and his wards by letting the demons come inside their house back then leading to all but one dying and Himejima being arrested and almost executed; again, to save his own cowardly ass.
  • Early-Bird Cameo: He briefly appears in Zenitsu's flashback in the anime.
  • Evil Cannot Comprehend Good: He only cared about himself and never understood any acts of goodness towards him, such as Zenitsu trying to defend his honor by punching a trainee who was talking behind his back, instead of criticizing Zenitsu for hitting some higher-ups. And even when he and Zenitsu would get into arguments, Zenitsu would try to get along with him anyway. Kaigaku just shrugs it off. And finally, he did not understand that his master wanted both him and Zenitsu to share the position of Pillar to fight as brothers-in-arms. Kaigaku only wanted the position to himself.
  • Evil Feels Good: He clearly takes pleasure in becoming a demon.
  • Evil Orphan: He's the same kid who told a demon to attack the temple where he and other orphans were taken care of by Himejima and put out demon repellent there in exchange for his life. Volume 17 confirmed it was after Kaigaku was outed by the other kids when they found out he had been stealing from their money savings.
  • Fatal Flaw: Selfishness. In the end, Kaigaku is driven by his own self-interest and preservation, including why he became a demon. Yushiro's speech to him remarks how his inability to care for others ultimately left him with nothing as he dies being beheaded by Zenitsu's invented Seventh Form Thunder Breath technique originally intended for fighting by his side.
  • Foil: To Zenitsu. While Zenitsu is a selfless Lovable Coward and a clever fighter who is more limited by his lack of confidence rather than any lack of talent, Kaigaku is a mean-spirited brute driven to mock and belittle others by an overwhelming fear of death.
  • Hate Sink: Think that, like the other Demons in the series, he's going to have a backstory that'll shed some light on his prior actions? Nope. In the end, all Kaigaku is a spiteful, unpleasant bully and a Dirty Coward who'd sell everyone out to save his own skin.
  • Hypocrite: He mocks Zenitsu's weakness and him being a coward while he became a demon partly to save himself from dying. If anything, he's more cowardly than Zenitsu.
  • It's All About Me: Kaigaku measures everything with how it corresponds to him, stating clearly that what's good for him is good and what isn't is evil. He couldn't comprehend why their mentor wanted him to share the successor position with Zenitsu wanting the position for himself.
  • Jerkass: Not just an evil demon. Kaigaku is also a total asshole.
  • Jerk with a Heart of Jerk: Might be that he has a sympathetic reason for being a demon? Nope, Kaigaku is just a nasty prick that only cares about himself.
  • Karmic Death: For all his mockery of Zenitsu's weakness, it turns out Kaigaku is unaware of the seventh Thunder Breathing form that Zenitsu invented and is easily dispatched by it.
  • Lack of Empathy: Instead of feeling saddened over his and Zenitsu's master's seppuku because of the betrayal that he caused, he insults their master and gloats about himself. This angers Zenitsu very much.
  • Lightning Bruiser: As befitting a Thunder Breathing user, Kaigaku's style is all about moving incredibly fast with powerful strikes. But since he couldn't obtain the first form, which is the foundation for all, his other forms are weaker than they should be.
  • Rival Turned Evil: Once Zenitsu's rival in the Thunder Breathing succession, Kaigaku became a man-eating demon for power and for his own survival.
  • Shadow Archetype: To Zenitsu. Kaigaku embodies pre-Character Development Zenitsu without any of his redeeming traits, prioritizing his own self-preservation above anything and everything else.
  • Shock and Awe: Becoming a demon gave him stronger electric powers to go with his Breath techniques.
  • Small Name, Big Ego: Of all the Upper Kizuki, Kaigaku goes down the quickest and easiest. It's more or less strongly implied he only got the position because Muzan had already lost three top Kizuki and needed to fill the spots quickly with the most impressive of the lower ranks (which Zenitsu bluntly points out). In any case, Kaigaku is far less impressive than he would want to boast.
  • This Cannot Be!: He's shocked and horrified Zenitsu manages to outmaneuver and behead him.
  • We Hardly Knew Ye: While he made appearances in Zenitsu's flashbacks, his debut in the main story as a servant of Muzan sees him lasting just a few chapters before Zenitsu kills him. Given how much it takes to kill the other members, this underscores just how pathetic he really was.
  • With Great Power Comes Great Insanity: Kaigaku was an unpleasant jerk as a human, but becoming a demon just made him into an absolute psychotic asshole.

Other

    Kyogai 

Kyogai

Voiced By: Junichi Suwabe

https://static.tvtropes.org/pmwiki/pub/images/kyougai_kny.jpg
Former Lower-6.
  • Abusive Parents: His father constantly belittled his work and cruelly denied him the approval he so desperately craved. Unsurprisingly, while his role in Kyogai's Start of Darkness was tragic, he was an Asshole Victim in the whole sordid affair.
  • Arc Villain: Of the Drumhouse arc. Though there are two other demons in the house that competed with him, they are easily killed by Inosuke and Zenitsu, so he ends becoming the main threat of the arc at the end.
  • Body Horror: As a demon, he has several drums sticking out on his shoulders, stomach, and legs.
  • Domain Holder: While not omnipotent within the Drum House, he is quite difficult to kill due to being capable of changing the orientation of the rooms at will and relocating people from one area to another (though he lost the latter power when another demon clawed out his back drum in a skirmish over food).
  • Drums of War: Kyogai can attack others with invisible clawing attacks within his domain by pounding on the drums embedded in his chest and shoulders. By pounding the drum on his back, he can forcibly transport someone to another room in his building. The drums on his shoulders and legs will change the orientation of the room via rotation.
  • Eye Scream: Muzan removed his number due to Kyougai having reached his limits to eating humans.
  • Last Request: All he wanted was someone to recognize his works. He finally gets this validation through Tanjiro's telling him that his techniques were strong after he decapitated him.
  • Musical Assassin: Uses taiko drums to manipulate reality in his house or to send out a disembodied strike in the shape of giant claws.
  • Perpetual Frowner: Through the arc, he is constantly shown as angry and frustrated due not being able to find Kiyoshi, and he's always frowning. He stops doing that after Tanjirou kills him and recognizes his strength.
  • Self-Made Orphan: His extreme negative emotions over his father's emotional and verbal abuse led to him becoming a demon, and his first drum was the one on his torso that creates an invisible slashing attack. Do the math.
  • Tears of Joy: He cries silent tears as he dies, as his talents were finally recognized by someone at the end of his life. This allows him to die peacefully.
  • Teleporters and Transporters: The drum that was originally on his back, has the ability to transport other people in random locations inside the drum house.
  • "Well Done, Son!" Guy: Was an aspiring writer and musician as a human, but his own father, whose approval he sought, constantly mocked and belittled his abilities.
