This is a list of characters of the manga series ''Demon Slayer: Kimetsu no Yaiba''.

Main characters

Tanjiro Kamado

:
: is the oldest son of a charcoal trader. His life changed when his entire family was massacred by the demon Muzan Kibutsuji while he was out selling charcoal. At the same time, his sister, Nezuko, survived but had been turned into a demon. This backstory drives his character's 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 Urokodaki, learning the sword style. Later, Tanjiro began using his family's technique based on the original breath style, . 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 wellbeing of his comrades, feeling guilt and sorrow after defeating his enemies. However, he is merciful and understanding of the demons he fights, as he can sense the pain, they have gone through. His endless optimism and simple nature often have people 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 and also allows him to figure out people's real emotions. Tanjiro's sword is colored black, occasionally turning crimson red. His sword technique becomes stronger 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. Still, thanks to his friends' efforts, he can become human once again.

Nezuko Kamado

:
: is the daughter of a charcoal-seller and Tanjiro's younger sister who was turned into a demon. Her character functions as motivation and support for Tanjiro. Despite Muzan's assumption that he killed them all in his attempt to sire a sun-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 Urokodaki, 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 Giyuu Tomioka, to keep from biting anyone. However in later volumes, the muzzle is removed and she gains the power of speech, albeit very broken due to not speaking for more than two years. Nezuko has several powers, including regeneration, superhuman strength, growing and shrinking rapidly, as well as a blood demon technique called that causes her blood to burn once it leaves her body. Tanjiro generally carries her around in a wooden box (a gift from Urokodaki) 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 Kibutsuji, and it is implied that she helps Tanjiro recover from his demon transformation by allowing him to ingest her blood, which contains antibodies for Muzan's demonic blood.

Zenitsu Agatsuma

:
: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, sometimes functions as comic relief. His cowardly personality is also used to contrast against Tanjiro's determined character. Zenitsu trained in the style by the former Thunder Hashira, but was only able to learn the first technique, 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 technique. 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.

Inosuke Hashibira

:
:A young boy who was raised by his mother Kotoha Hashibira for a short time until she was murdered by demons known as the Upper Moon Two, Doma of the Twelve Kizuki. After she sacrificed herself to save his life, he was raised by wild boars, and then taught to read and write by an old man. uses a self-taught style called , 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 actually 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 spirit. He took the Demon Slayer Corps test at the same time as Tanjiro and Zenitsu and was apparently the first to clear it. Inosuke's swords are colored blue-grey. He has a heightened sense of touch, being able to locate enemies by feeling the vibrations in the air.

Kanao Tsuyuri

:
: joins the Demon Slayer Corps at the same time as Tanjiro, Zenitsu and Genya. She is the protegé of Shinobu Kochō, 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 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. It is also implied that she may have feelings for Tanjiro, to the point of risking her life to help save him when he was turned into a demon. Later in the series, it has been shown that she and Tanjiro had descendants, thus confirming her romantic relationship with Tanjiro. Kanao's sword is colored 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 Kamado and Sumihiko Kamado between them.

Genya Shinazugawa

:
:Another Demon Slayer who joins at the same time as Tanjiro Kamado and Zenitsu Agatsuma. 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 Breaths or most 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 greater depending on the strength and the amount of the demon he devours. When he devours part of a demon, he is also susceptible to a demon's weaknesses. He also carries a shotgun that shoots specialized bullets that are made of the same material as the Demon Slayers' Nichirin blades as well as a Nichirin wakizashi. He is the younger brother of Sanemi Shinazugawa, 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.

But Nezuko becomes an exception after learning more about her. Unlike the other Hashira, she does not have the strength to behead them, using instead a small, thin sword with only a cutting edge on the tip 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.

He is infatuated with Mitsuri and gets easily jealous when she becomes close to someone else.

Demons

The are immortal creatures who feed on human flesh and blood to survive and become stronger with each human they devour. All demons are former humans who lose most of their memories and almost all traces of humanity after drinking or being injected with Muzan Kibutsuji's blood becoming his servants and sharing their own vision and thoughts with him. Higher Demons are also capable of casting powerful magic spells called . The specifics of these spells are unique to each Demon.

All Demons are weak to sunlight, being easily destroyed upon being exposed to it, but they can be also killed by decapitation with special swords used by the Demon Slayers called . Demons also are highly intolerant to wisteria flowers, avoiding places where such plants are abundant and wisteria extract can be lethal to them in high doses.

Muzan Kibutsuji

:
:The primary antagonist of the series, 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 having no weaknesses, the sun being his only one. He also expressed a justified concern towards those who utilized the Breath of the Sun technique since his near death experience from fighting Yoriichi Tsugikuni. 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 to capture and devour her to remove his only weakness. But 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 human with his friends' help.

Twelve Kizuki

The is a special group of demons serving under Muzan, with a special mark of their membership engraved on their eyes. There are six lower moons. 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 decides to eliminate the current Lower Ranks and have only the current Upper Ranks under his command.

Upper Ranks

The high-ranking members of the Twelve Moons. 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 cannot 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.

;
:Muzan's most powerful subordinate holding the title of Upper One, Kokushibo was originally a Demon Slayer called 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. Kokushibo has a more human-like appearance and uses breathing styles. His fighting style is , 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. Kokushibo instantly regenerates his head after being decapitated by Gyomei. His final form has an intimidating demonic appearance which is the reason behind him losing his will to fight and accepting his defeat.

One member of his cult was Inosuke's mother, whom he devoured when she ran away from him upon learning his true nature. He also killed Shinobu's older sister Kanae.

Supporting characters

;
:
:A former Water Hashira; He is introduced to Tanjiro and Nezuko by his student Giyu. He is initially apprehensive of Tanjiro's kind nature, but agrees to train him. As the training goes on, he grows closer to both Tanjiro and Nezuko, and he sheds tears of joy, when Tanjiro returns from the Demon Slayer exam alive, as he is the first to do so after a long string of deaths. He has since kept a close eye on their growth. He has given his word to the Pillars that if Nezuko were to eat a human, then Tanjiro, as well Giyu and himself would kill her and themselves in atonement.
;
:
:One of Urokodaki's disciples. He died during an exam to join the Demon Slayer Corps while trying to save other students who were not as strong as himself, Giyu being one of them.

;
:
:A sparrow who was the only of his species to pass the exam to work as a Kasugai Crow. Assigned to Zenitsu, who nicknames him , he usually reprimands him when he shows cowardice.
;
:
:A talented doctor who is also a demon. She was converted into a demon by Muzan, which resulted in her killing and eating her family to her horror. Despite that, she was under Muzan's control until the demon was almost killed by Yoriichi Tsugikuni who also spared her. She further altered herself to allow her to survive on a small amount of blood and no flesh. She is attempting to find a cure for demons, but requires the blood of special demons. To this end, she enlists help from Tanjiro, who offers some of Nezuko's blood as well as trying to get blood samples from members of the Twelve Kizuki. She can also create demons—the only other demon beside Muzan who can—but she insists on only doing it for dying patients who have no other option and ensures they know the price of becoming a demon. After completing her research on a cure for Nezuko's condition, Tamayo sacrifices herself to lay an ambush on Muzan with Kagaya's help but despite failing to kill her sworn enemy, she poisons the demon with a mix of substances she developed with Shinobu's help to greatly weaken him.
;
:
:A demon created by Tamayo. He cares for her greatly and is very protective of her. It has been implied that he loves her. He is the only demon made by Tamayo and as such, has no connection to Muzan. He only needs a small amount of blood to survive, even less than Tamayo. He is mentioned to have a "battle form" which he can change into. He has a special power which can erase the presence of living things as well as make the unseen seen. This technique is not perfect and the more people he attempts to hide, the easier it is to find them. After his master's death, Yushiro assists the Demon Slayers in the final battle against Muzan by providing aid to the wounded soldiers and helping Tanjiro and his friends evade Muzan's attacks with his detecting scrolls. After Muzan's defeat, Yushiro keeps living as a demon all the way to the modern times, where he makes a living as a painter.

:
:Kokushibo's younger twin brother who became a Demon Slayer after his pregnant wife was killed by a demon. He was the one who created the Sun Breathing and was so powerful that he once cornered and almost defeated Muzan by himself, but failed to destroy him completely, despite inflicting multiple wounds on the demon that never healed. He was later expelled from the Slayer Corps once they also learned that he let Tamayo live and his brother became a demon. He later befriends Tanjiro's ancestors and teach them the Sun Breathing, which they pass on to their lineage in the form of the Hinokami Kagura, along the same hanafuda earrings always used by Tanjiro. He died of old age during a fight with his brother.
