List of Demon Slayer: Kimetsu no Yaiba characters

Voiced by: Natsuki Hanae,[1] Satomi Satō (child)[2] (Japanese); Zach Aguilar,[3] Allegra Clark (child)[4] (English)

Tanjiro Kamado (竈門 炭治郎, Kamado Tanjirō) is the oldest son of charcoal sellers Tanjuro and Kie. His life changed when his entire family was massacred by the demon Muzan while he was out selling charcoal. At the same time, his sister, Nezuko, survived but had been turned into a demon. This event becomes his drive and motivation to find a cure for her and turn her back into a human. To this end, he decided to join the Demon Slayer Corps. He initially trained under Sakonji, learning the "Water Breathing" (水の呼吸, Mizu no kokyū) sword style. Later, Tanjiro began using his family's "Hinokami Kagura" (ヒノカミ神楽, lit. Dance of the Fire God) technique based on the original breath style, "Sun Breathing" (日の呼吸, Hi no kokyū). Tanjiro would then merge both methods to create a more sustainable fighting style. His skull is exceptionally thick, and his headbutts are used as gags throughout the series. He is characterized as a pure and kind-hearted individual, always looking after the well-being of his comrades and sympathizing with the plight of demons. Nonetheless, he possesses an understanding that their actions cannot be forgiven. His endless optimism and simple nature enable most people to enjoy his company. Still, at the same time, it also puts him at odds with certain personalities. Tanjiro has a heightened sense of smell which allows him to track down demons and evade their attacks, as well as determine people's real emotions. Tanjiro's sword is colored black, occasionally turning crimson red. His sword technique becomes enhanced when combined with Nezuko's "Blood Demon Art: Exploding Blood", a method he later learns to perform without her help. Though he eventually avenges his family during the final battle, he loses his left arm and right eye in the process while being fatally wounded. Both are restored during Muzan's attempt to turn him into his successor by transforming him into a demon, though with the aid of his friends, he becomes human once again.

Nezuko Kamado (竈門 禰豆子, Kamado Nezuko) is the oldest daughter of a charcoal-selling family and Tanjiro's younger sister. She was turned into a demon during her family's massacre. Her character functions as motivation and support for Tanjiro. Despite Muzan's assumption that he killed them all in his attempt to sire a sunlight-resistant demon, Nezuko survives as a demon with her mind mostly gone. However, she retains enough of her memories to keep herself from killing Tanjiro. Due to two years of hypnotic conditioning by Sakonji, Nezuko regards all humans as her family and will mercilessly attack any demon that threatens them. Instead of consuming human flesh, Nezuko regains energy from sleep and tends to become unconscious for long periods of time after overexerting herself. Initially, she is unable to speak and must wear a bamboo muzzle, given to her by Giyu, to keep from biting anyone. However in later volumes, the muzzle is removed and she gains the power of speech, albeit broken due to not speaking for more than two years. Nezuko has the standard powers of demons, including regeneration, superhuman strength, growing and shrinking rapidly, and a Blood Demon Art called "Exploding Blood" (爆血, Bakketsu) that causes her blood to burn once it leaves her body. Tanjiro generally carries her around in a wooden box (a gift from Sakonji) until she develops the ability to survive exposure to sunlight, with Muzan targeting her soon after. Nezuko's mind and humanity are eventually restored during the final battle against Muzan.

An extremely cowardly boy who was forced to join the Demon Slayer Corps at around the same time as Tanjiro to pay for his debts, Zenitsu Agatsuma (我妻 善逸, Agatsuma Zen'itsu) sometimes functions as comic relief. His cowardly personality is also used to contrast with Tanjiro's determined character. Zenitsu trained in the "Thunder Breathing" (雷の呼吸, Kaminari no kokyū) style by the former Thunder Hashira but was only able to learn the first form, and because of this he often belittles himself, despite the fact that he is talented. He joins up with Tanjiro on a mission and since then, he has tagged along with him, partially out of his infatuation with Nezuko, but also due to recognizing how honest and kind he is. His cowardly personality initially hinders him and he is only able to fight when he is unconscious or asleep, but he later learns to push his fears aside and take action when needed, to the point of developing a new, exclusive Thunder Breathing form. Zenitsu's sword is colored yellow and has a lightning bolt design. He has a heightened sense of hearing which allows him to distinguish a person's true character by the sound of their heartbeat and track demons.

A young boy who was raised by his mother Kotoha for a short time until she was murdered by a demon, later revealed as Upper Rank Two, Doma of the Twelve Kizuki. After she sacrificed herself to save his life, he was raised by wild boars, and then taught to talk by an old man. Inosuke Hashibira (嘴平 伊之助, Hashibira Inosuke) uses a self-taught style called "Beast Breathing" (獣の呼吸, Kedamono no kokyū), along with two serrated swords in battle. When he gets new swords, he purposely chips them in order to match his preference and fighting style (much to his swordsmith's anger). Like Zenitsu, Inosuke is occasional comic relief for the series. He is portrayed as brash and prone to reacting violently, and while he appears dim, he proves himself in battle time after time. He is drawn as extremely muscular and rugged, which contrasts with his oddly effeminate face, which he normally hides under a boar's head mask. This mask was made from the head of his deceased boar mother, and he wears it in memory of her. When Inosuke first meets Tanjiro, he treats him as an enemy, but they quickly become friends as they fight together. He often challenges Tanjiro to competitions that are accepted in good spirits. He took the Demon Slayer Corps test at the same time as Tanjiro and Zenitsu and, unknown to most, became the first to clear it. Inosuke's swords are colored indigo gray. He has a heightened sense of touch, being able to locate enemies by feeling the vibrations in the air. Inosuke cannot read or write, and often forgets names or gets them completely wrong.

Kanao Tsuyuri (栗花落 カナヲ, Tsuyuri Kanao) joins the Demon Slayer Corps at the same time as Tanjiro, Zenitsu, and Genya. She is the protegé of Shinobu, the current Insect Hashira, and is being trained as a Tsuguko, or successor to the Hashira - however, it does not necessarily mean that she is an Insect Hashira nor has the same "breathing technique" as Shinobu. She uses the "Flower Breathing" (花の呼吸, Hana no kokyū) style and is a highly-skilled fighter, but has difficulty functioning without being directly told what to do. She grew up in a poor, abusive household and was sold as a slave, leading her to shut off her emotions as a way to cope. Even after being rescued and taken in by Shinobu and Kanae, she would never do anything unless ordered, so Kanae gave her a coin to flip which she could use whenever she had trouble making decisions. She relies heavily on her coin flipping to make decisions until Tanjiro becomes friendly with her, which convinces her to use the coin less often and stick to her own intuition. She develops feelings for Tanjiro, to the point of risking her life to help save him when he was turned into a demon. Kanao's sword is colored light pink and her heightened sense of sight allows her to easily dodge enemy attacks, but she strains herself by overusing this ability during her fight with Doma, to the point of becoming blind in one eye. She is later revealed to have married Tanjiro, having two great-great-grandsons named Kanata and Sumihiko between them.

Another Demon Slayer who joins at the same time as Tanjiro and Zenitsu. Genya Shinazugawa (不死川 玄弥, Shinazugawa Gen'ya) is portrayed as a harsh and foul-mouthed individual obsessed with nothing beyond demon killing. His personality later changes after he fights beside Tanjiro to save the hidden Swordsmith Village. Unlike most other Demon Slayers, he is unable to use breathing techniques or traditional sword fighting styles. Instead, he eats parts of the demons he fights, and through his special digestive system, he temporarily gains demonic powers. His powers can be lesser or greater, depending on the strength of the demon he devours. When he utilize a demon's powers, he is also susceptible to a demon's weaknesses. Genya also carries a shotgun that shoots specialized bullets that are made of the same material as the Demon Slayers' Nichirin sword as well as a Nichirin wakizashi. He is the younger brother of Sanemi, the current Wind Hashira, who always avoids him, unaware that his older brother wants him to have a normal life. Genya is mortally wounded while assisting the Hashira against Kokushibo, reconciling with his brother before passing away. In the Reiwa Era, he and his brother are reincarnated as police officers.

The 97th leader of the Demon Slayer Corps whose family established the organization.

After the death of his father, Kiriya quickly steps in as Kagaya's successor, commanding the Demon Slayer Corps in the final battle against Muzan and his forces. After Muzan's death, Kiriya officially disbands the Demon Slayer Corps, as their mission to vanquish Muzan and his demons was accomplished. Later it is shown that he became the longest-living person in Japan, still alive after the time skip to the modern times that occurs in the last chapter.

Kuina Ubuyashiki (産屋敷 くいな, Ubuyashiki Kuina)

Giyu Tomioka (冨岡 義勇, Tomioka Giyū)

Voiced by: Takahiro Sakurai[5] (Japanese); Johnny Yong Bosch[3] (English)

The current Water Hashira. He is the first Demon Slayer that Tanjiro comes across. He initially tries to kill Nezuko but reconsiders after seeing her protect an unconscious Tanjiro. He sends them to his mentor Sakonji in the hopes that Tanjiro could succeed him and possibly cure Nezuko. Seemingly aloof and unemotional, he does not think of himself as a true Hashira, despite mastering Water Breathing, due to an inferiority complex that stemmed from survivor's guilt during Final Selection. He has developed an additional exclusive form of Water Breathing, which he alone knows. He loses an arm during the final battle against Muzan but survives after the demon is killed. In the Reiwa Era, Giyu's reincarnation/descendant is a child named Giichi, who is close friends with Sabito and Makomo's reincarnations.

Shinobu Kocho (胡蝶 しのぶ, Kochō Shinobu)

Voiced by: Saori Hayami[17] (Japanese); Erika Harlacher[18] (English)

The current Insect Hashira. She is rather cool-headed and always has a smile on her face, no matter what situation she is put in. She enjoys teasing others, mostly annoying Giyu, about how no one likes him. Behind her cheerful facade, she harbors a deep rage towards all demons for taking the lives of her loved ones, including her older sister. Unlike the other Hashira, she does not have the strength to behead them, using instead a small, thin sword to kill demons by inoculating them with a wisteria-based poison she developed. Shinobu sacrifices herself to defeat Doma, having consumed massive doses of wisteria so Doma would be poisoned the moment he devoured her with Kanao and Inosuke finishing him off. Before her death, she also helped Tamayo with developing the cure for Nezuko's demon condition and a mix of poisons used on Muzan to greatly weaken him. In the Reiwa Era, she and Kanae are reincarnated as high school students.

Her Japanese last name 胡蝶 (Kochō) means "butterfly".

Kyojuro Rengoku (煉獄 杏寿郎, Rengoku Kyōjurō)

Voiced by: Satoshi Hino,[19] Mariya Ise (child) (Japanese); Mark Whitten,[20] Ryan Bartley (child)[21] (English)

The current Flame Hashira after inheriting the title from his father Shinjuro. Though he comes off as boisterous and cheerfully eccentric, Kyojuro is pure-hearted and honorable due to his mother instilling in him a moral code of protecting the weak. He was assigned to investigate the Mugen Train, with Tanjiro, Zenitsu, Inosuke, and Nezuko aiding him to dispatch Enmu. After their battle with Enmu, he meets Akaza of the Twelve Kizuki. Akaza proposes that Kyojuro turn into a demon so they can fight for all of eternity, to which Kyojuro flatly declines. He is ultimately killed by Akaza. After using his last moments to direct Tanjiro to his father, the youth had the tsuba of Kyojuro's broken sword installed into his new sword in respect of the Hashira. In the Reiwa Era, he is reincarnated as a teenage student.

Tengen Uzui (宇髄 天元, Uzui Tengen)

Voiced by: Katsuyuki Konishi[19] (Japanese); Ray Chase[20] (English)

The current Sound Hashira and former shinobi. Exuberant and proud, Tengen always strives to do things "flashy". While he is somewhat arrogant and condescending, Tengen harbors deep regrets over his life as a shinobi like being forced to kill some of his siblings when their father ordered it, joining the Demon Slayers in the hope to atone for it. He has three wives who served as kunoichi and assist in his mission, eventually retiring as a Hashira after losing his left hand and eye from fighting Gyutaro. He reappears in the final battle against Muzan, standing guard to protect Kiriya alongside Kyojuro's father. In the Reiwa Era, Tengen has a reincarnation/descendant named Tenma, an athlete who wins a gold medal in gymnastics.

Mitsuri Kanroji (甘露寺 蜜璃, Kanroji Mitsuri)

Voiced by: Kana Hanazawa[19] (Japanese); Kira Buckland[20] (English)

The current Love Hashira and a former disciple of Kyojuro. She has an overtly passionate, somewhat airheaded disposition. Her whip-like sword is made from a malleable metal that only she can properly wield. She possesses enhanced flexibility and abnormal physical strength due to having denser muscles than the average human. She joined the Demon Slayer Corps because she wanted a man that would love her to be stronger than her. She especially admires the other male Hashira and would always praise them in her mind. Thus, when she was mortally wounded during the final battle against Muzan, she declared her love for Obanai, before dying alongside him. The epilogue shows her reincarnation in the Reiwa Era married to Obanai's as they run a restaurant together.

Voiced by: Kengo Kawanishi[19] (Japanese); Griffin Burns[20] (English)

The current Mist Hashira. Outwardly nonchalant and indifferent, he possesses a fierce rage against demons that acts as his driving force to fight. He had an older twin brother who was killed by a demon when they were younger. Since then, he has always blamed himself for being the only survivor until Tanjiro manages to cheer him up. Due to the incident, he lost some of his memories, which was restored after realizing Tanjiro had the same red eyes as his father. He is killed in the battle against Upper Rank One, Kokushibo, who is revealed to be his distant ancestor. In the Reiwa Era, he is reincarnated as a baby alongside his brother.

He pities Tanjiro at first due to Nezuko being a demon, but later acknowledges him after seeing how honest he is. He is the only Hashira who does not use a sword, fighting with an enormous flail-like chained axe that only he can wield with ease due to his massive size and strength.

He was raised by his family, an all-female clan of bandits, as an offering to a serpentine demon they worshiped, only to be rescued by Shinjuro. He joined the Demon Slayer Corps as a means of venting his rage over how his family was destroyed by their association with the demon. He is infatuated with Mitsuri and gets easily jealous when she becomes close to someone else. Despite being blinded during the final battle with Muzan, he still manages to assist Tanjiro due to his connection with Kaburamaru, which allows him to continue fighting. He ends up mortally wounded and declares his love for Mitsuri, before dying alongside her. After his death, Kaburamaru's care is entrusted to Kanao.

The former Flower Hashira. Shinobu's late biological older sister and Kanao's late adoptive older sister. She was killed by Doma, Upper Rank Two of the Twelve Kizuki. In the Reiwa Era, she and Shinobu are reincarnated as academy students.

Voiced by: Toshihiko Seki[30] (Japanese); Greg Chun[31] (English)

Muzan Kibutsuji (鬼舞辻 無惨, Kibutsuji Muzan) was the first and strongest demon in existence. He used his blood to sire the other demons. He was able to manipulate his cellular structure and frequently disguised himself as different humans of various ages and genders. He would program transplanted cells within demons he directly sired to destroy them if they ever mentioned him by name. He could devour the cells of others to assimilate their abilities and memories as well. Muzan was originally a sickly young man from the Heian period whose transition into a demon was the result of an experimental treatment to prolong his life. He killed his doctor before realizing it worked. Muzan has since dedicated himself to "complete his treatment" by siring demons that would help him achieve his goal of overcoming his one weakness, sunlight. He also expressed a justified concern towards those who utilized the Sun Breathing technique since his near-death experience from fighting Yoriichi. This motivated him to attack Tanjiro's family in an attempt of turning at least one of them into a demon that was naturally immune to sunlight. Nezuko, the only survivor of the incident, eventually manifested that ability and Muzan focused his efforts on capturing and devouring her to remove his only weakness. The Demon Slayer Corps exploited Muzan's obsession and laid a trap for him which killed his remaining followers. Muzan killed Tamayo and many Demon Slayers before realizing that he was infected with a variation of the humanity-restoring serum that Tamayo and Shinobu developed with added poisons that removed most of his abilities and weakened him to be easily killed. This resulted in his body being destroyed by the sunlight when he is held back by the Demon Slayers. Muzan's final act of revenge was to turn Tanjiro into a new demon so he would kill the Demon Slayers. This was thwarted when Tanjiro turned back into a human with his friends' help.

The Twelve Kizuki (十二鬼月, Jūnikizuki) is a special group of demons serving under Muzan, with a special mark of their membership engraved on their eyes. Second only to Muzan, they are the most powerful demons to have lived. The six weakest are known as the Lower Ranks and have a single eye engraved, while the six strongest are called the Upper Ranks and have both eyes engraved. After Rui's death, Muzan decided to eliminate the current Lower Ranks and have only the current Upper Ranks under his command.

The Upper Ranks (上弦, Jōgen) are the high-ranking members of the Twelve Kizuki. Each of them has lived for a century at least and killed dozens of Hashira. Some of them mutated their bodies to the point that they could not be killed just by decapitation, unlike other demons. Their ranks were unaltered for decades and no Demon Slayer had managed to kill any of them prior to Tanjiro and his friends joining the organization.

Kokushibo (黒死牟, Kokushibō)

Voiced by: Ryōtarō Okiayu[32] (Japanese); Jonah Scott[33] (English)

Muzan's most powerful subordinate holding the title of Upper Rank One, Kokushibo was originally a Demon Slayer called Michikatsu Tsugikuni (継国 巌勝, Tsugikuni Michikatsu) and the older twin brother of Yoriichi. Envious of his brother's talent, he ends up tempted to join Muzan's side as a demon in order to eternally perfect himself as a swordsman without the worry of dying of sickness or old age. As a transformed Demon Slayer, Kokushibo uses a breathing style known as "Moon Breathing" (月の呼吸, Tsuki no kokyū), which directly derives from Yoriichi's Sun Breathing. He dies while fighting a combined effort of Gyomei, Sanemi, Genya, and Muichiro, with the latter two dying from their wounds soon after.

Doma (童磨, Dōma)

Voiced by: Mamoru Miyano[34] (Japanese); Stephen Fu[35] (English)

A nihilistic demon who holds the position of Upper Rank Two. As a child, he was seen by his parents as a perfect, blessed child, thus they started a religious cult around his figure. After his parents' deaths, he assumed control of the cult and after being transformed into a demon by Muzan, he started eating his followers on the notion that those he devoured will live forever inside him. One member of his cult was Inosuke's mother Kotoha, whom he devoured when she ran away from him upon learning his true nature. He also killed Shinobu's older sister Kanae. In a desperate measure to defeat him, Shinobu administers a massive dose of wisteria in her body and allows herself to be consumed by him. The weakened Doma is later killed by Kanao and Inosuke.

Akaza (猗窩座)

Voiced by: Akira Ishida[36] (Japanese); Lucien Dodge (English)

Holding the position of Upper Rank Three, he is a demon who despises whoever he considers weak and offers those he considers strong enough to have his respect the chance to become demons. He was once a human called Hakuji (狛治) who stole as a child to care for his ailing father before he committed suicide to free his burdened son. Hakuji was adopted by a martial artist named Keizo and trained under him while falling in love with his master's daughter Koyuki. Hakuji loses his new family when they were poisoned by a rival dojo who were unable to beat him in a fair fight, leading him to slaughter them all single-handedly before being turned into a demon by Muzan. Akaza fatally wounds and kills Kyojuro and later battles Tanjiro and Giyu. During their battle, he regains his human memories and commits suicide by voluntarily ceasing his regeneration and dying from his wounds.

Hantengu (半天狗)

Voiced by: Toshio Furukawa (original)[32] Yūichirō Umehara (Sekido),[37] Kaito Ishikawa (Karaku),[37] Shunsuke Takeuchi (Urogi),[37] Soma Saito (Aizetsu),[37] Koichi Yamadera (Zohakuten)[38] (Japanese); Christopher Corey Smith[39] (English)

A seemingly weak demon who holds the position of Upper Rank Four, Hantengu shows his true strength upon dividing himself into multiple clones which denote different emotions and names: Sekido; Karaku; Aizetsu; Urogi; Zohakuten and Urami. Each has a different appearance, personality, and ability. He was originally a prolific criminal who continuously boasted of his innocence despite conviction before being turned into a demon by Muzan. He is killed by Tanjiro but lives long enough to inform Muzan about Nezuko's newfound resistance to sunlight.

Nakime (鳴女)

Voiced by: Marina Inoue[40] (Japanese); Amber Lee Connors (English)

A biwa-playing demon who owns and manipulates the Infinity Castle (異空間無限城, Ikūkan Mugen-jō, Dimensional Infinity Fortress) that Muzan made his base of operations. She was once a struggling musician who developed a habit of murdering prior to a performance as she associated her killings with applause thanks to killing her husband for selling her items. She ended up meeting Muzan when she tried to kill him, only to earn his respect for tracking him and granting her new life as a demon. Nakime is later promoted to Upper Rank Four after Hantengu's death. Nakime confronts Mitsuri and Obanai until she is restrained by Yushiro, prompting Muzan to kill her to prevent his enemies from taking control of the fortress.

Gyokko (玉壼)

Voiced by: Kohsuke Toriumi[32] (Japanese); Brent Mukai[41] (English)

A demon with a distorted appearance who always nests himself into a jar, Gyokko holds the position of Upper Rank Five. He was once an ostracized villager who developed an obsession with corpses after his parents drowned out at sea and their bodies washed up on shore. He kidnaps and kills a child before being stabbed in revenge and left for dead, eventually being transformed by Muzan. He claims himself to be an artist and is incredibly proud of his creations, one of which is twisting his victims' bodies and turning them into grotesque, living sculptures. His immense self-pride goes so far as to attempt to break Hotaru's concentration by attacking him while he was sharpening a sword instead of killing him since he wanted to prove himself as the better artist. He is killed by Muichiro.

Daki (堕姫)

Voiced by: Miyuki Sawashiro[42] (Japanese); Erica Lindbeck[43] (English)

A demon disguised as an oiran, Daki shares the position of Upper Rank Six with her older brother Gyutaro, both taking advantage of her work in the red-light district to attract their victims. Her human name was Ume (梅, lit. syphilis), named after the disease that killed her mother, raised by Gyutaro in the red-light district slums they were born in. Her great beauty led to success in the district at a young age despite her volatile personality, until she was burned alive at age 13 by a samurai customer she blinded in the eye. She was on the verge of dying along with Gyutaro but was met by Doma, who made them demons and inherit his rank in the Upper Ranks. She uses an obi belt to absorb her victims and place them in a secret location before devouring them, serving as both her weapon and a semi independent extension of herself. She is beheaded by Zenitsu and Inosuke. After her death, Daki returns to her former appearance as Ume and meets Gyutaro in the afterlife. Ume refuses to leave Gyutaro's as he tries to pushing her away in an attempt to spare his sister an eternity in Hell, reminding her brother of their promise to survive anything together.

Gyutaro (妓夫太郎, Gyūtarō)

Voiced by: Ryōta Ōsaka[44] (Japanese); Brandon McInnis[45] (English)

A demon with a hideous appearance, Gyutaro shares the position of Upper Rank Six with his younger sister Daki. As a human born in the red-light slums, he was ostracized and despised for his appearance due to being abused by his mother. Ume's presence gave him joy and allowed him to embrace his vile disposition while making a living as a debt collector, only to be mortally wounded after killing a customer who burned Ume alive and then turned into demon by Doma. He usually hides within Daki's body and emerges whenever her life was threatened. He fights using his poisonous blood and two demonic sickles, as the basis of his Blood Demon Art. As dual holders of Upper Rank Six, Gyutaro needs to be decapitated together with Daki to be truly killed. He is beheaded by Tengen and Tanjiro, having regrets over being a bad influence in his sister's life and almost lashing out in response to her insults in her final moments. While he resolved in going to Hell alone to atone for both their sins, Ume refuses to leave his side and he relents.
