Pillars), who serve as its elite warriors.
Ubuyashiki family
Kagaya Ubuyashiki
The 97th leader of the Demon Slayer Corps, whose family established the organization. He is a distant relative of Muzan, resulting in his bloodline being cursed with a disease that slowly kills them before reaching their thirties due to their connection with Muzan's blood. He is gentle but firm and has dedicated himself to leading the Corps, garnering the respect of the Demon Slayers he commands. He sacrifices himself to weaken Muzan with a suicide bombing, exploiting Muzan's sadistic pleasure in listening to his last words before supposedly killing him.

Hashira
Gyomei Himejima
The Stone Hashira, regarded as the most powerful combatant in the Demon Slayer Corps. A former monk, he was falsely imprisoned after children under his care were killed by a demon, leading him to be distrustful and cynical. He initially distrusts Tanjiro Kamado due to his sister's demon nature but later acknowledges his integrity. He wields a massive kusarigama instead of a standard Nichirin sword. Gyomei plays a critical role in the battles against the Upper Rank demon Kokushibo and Muzan Kibutsuji, during which he loses a leg. He succumbs to his injuries after Muzan's defeat.
Muichiro Tokito
The Mist Hashira, an aloof yet secretly caring figure. A descendant of Demon Slayers of the past, he was orphaned as a child with only his older twin brother Yuichiro as family. After Yuichiro was killed protecting him from a demon, he suffers survivor's guilt, becoming an amnesiac and losing his childhood memories. He is initially distrustful of Tanjiro, but becomes much more friendly to him after regaining his memories and coming in terms with his survival. During the attack on the Swordsmith Village, he defeats Gyokko. Muichiro is killed in action against Kokushibo, who is revealed to be his distant ancestor. In the Reiwa era, he and his brother are reincarnated as infant twins.
Mitsuri Kanroji
The Love Hashira and a former disciple of Kyojuro Rengoku, who is passionate and somewhat airheaded. Unlike her fellow Demon Slayers, she did not join the Corps due to tragedies caused by demons, rather doing so in a way to be herself instead of conforming to society and marrying. She possesses enhanced flexibility and physical strength because of her dense musculature, and wields a whip-like Nichirin sword. She has an interest in cooking, able to make pancakes which are unseen in the Taishō era. She is pivotal in the defeat of Hantengu at Swordsmith Village and later battles his successor Nakime alongside Obanai. During the final battle against Muzan, she is mortally wounded and declares her love for Obanai, dying alongside him. In the Reiwa Era, they are reincarnated as a married couple who work as restaurateurs.
Kyojuro Rengoku
The Flame Hashira and successor to his father Shinjuro. Though he comes off as boisterous and eccentric, he is pure-hearted and honorable, as his mother instilled in him a moral code of protecting the weak. He is assigned to investigate the Mugen Train, with Tanjiro, Zenitsu, Inosuke, and Nezuko aiding him in dispatching Enmu. After the battle, Akaza confronts him and proposes that he turn into a demon, having recognized his skill and strength. Kyojuro rejects this and battles him, but is ultimately killed. In his last moments, he directs Tanjiro to Shinjuro on his quest to discover more about Hinokami Kagura. Tanjiro later has the tsuba of Kyojuro's sword installed into his new sword to honor him. In the present day, he is reincarnated as a high school student named Tojuro, who is also his descendant through his younger brother.
Giyu Tomioka
The Water Hashira and the first Demon Slayer that Tanjiro meets. He initially tries to kill Nezuko but reconsiders after she protects Tanjiro from him, and directs them to his mentor Sakonji Urokodaki in hopes that Tanjiro could succeed him and possibly cure Nezuko. Beneath his aloof and unemotional exterior, he suffers from an inferiority complex stemming from survivor's guilt during Final Selection, where his best friend Sabito dies after killing all but one demon, leading him to be unconfident in his skills as a Hashira. He developed an additional self-taught form of Water Breathing. Giyu and Tanjiro battle Akaza in the Infinity Castle, and later are the first to face Muzan. He loses his left arm during the battle, but survives. Giyu has a descendent in the present day named Giichi, who is close friends with Sabito and Makomo's reincarnations.
Shinobu Kocho
The Insect Hashira and sister of Kanae. Her surname, Kochō (胡蝶), means "butterfly", hence her motif. She is seemingly cool-headed and optimistic and enjoys teasing others, particularly Giyu, but beneath her cheerful façade is a constantly angry and vengeful figure motivated solely by her hatred of demons, who killed her family one after another, to the point of deriving sadistic pleasure from killing demons. However, she is caring towards humans, including her subordinates, Tsuyuri Kanao and the Kamados after Nezuko was allowed to stay. Due to her small frame preventing her from traditionally beheading demons, she wields a thin, sting-like Nichirin sword to inject them with a wisteria-based poison she made. This expertise allows her to assist Tamayo in developing the cure for Nezuko and in concocting a mixture of drugs to weaken Muzan, working with her despite her initial hatred for Tamayo's demon status. Shinobu sacrifices herself to defeat Doma, having previously taken massive doses of wisteria to ensure he would be poisoned when he devoured her, allowing Kanao and Inosuke to kill him. In the present day, she and Kanae are reincarnated as high school students.
Tengen Uzui
The Sound Hashira and a former shinobi. He is exuberant and prideful, always striving to do things in a flamboyant manner. Despite being arrogant and condescending towards others, he harbors deep regrets over his former life as a shinobi, including being forced to kill his siblings on his father's orders; he joined the Demon Slayers to atone for his sins and regrets. He has three wives who served as kunoichi and assist him in his mission. He retires as the Sound Hashira after losing his left hand and eye while fighting Gyutaro. He later assists in the final battle against Muzan, protecting Kiriya alongside Shinjuro. In the Reiwa Era, Tengen has a descendant named Tenma, who is an Olympic gymnast and acts in a similarly arrogant manner towards others.
Sanemi Shinazugawa
The Wind Hashira, who is confrontational and aggressive; even after failing in his attempt to prove Nezuko's demonic nature to the Hashira and Kagaya, he does not accept the Kamado siblings. As a teen, he witnessed the deaths of his siblings and was forced to kill his mother, who had been transformed into a demon. He is the older brother of Genya, his only surviving sibling, and continually shuns him to unsuccessfully have his brother quit the Demon Slayer Corps so he can live a normal life. Along with Giyu, he is one of two Hashira to survive the final battle against the Upper Ranks and Muzan, but loses two right fingers during his battle against Kokushibo. In the present day, he has a descendant who is a police officer along with Genya's reincarnation.
Obanai Iguro
The Serpent Hashira, who is accompanied by his companion snake, Kaburamaru. He is toxic and ruthless towards others, suffering from deep self-loathing because of his past. His family, an all-female clan of bandits, raised him to be an offering to a serpentine demon they worshipped simply for being the first male in their lineage in years, when Shinjuro Rengoku rescued him. He joined the Demon Slayer Corps as a means to vent his rage at his family being destroyed through their association with the demon. He is in love with Mitsuri, being unusually open and relaxed in her presence, and is jealous when she apparently becomes close to others. During the final battle, he and Mitsuri battle Nakime before joining the fight against Muzan, in which he and Kaburamaru provide assistance. After the battle, he declares his love for Mitsuri and dies alongside her from his sustained wounds, with Kaburamaru's care being entrusted to Kanao. In the present day, he and Mitsuri's reincarnations are happily married and run a restaurant together.

Murata
A member of the Demon Slayer Corps who is sent to Natagumo Mountain. He is one of the survivors of the operation to slay the Spider Family and befriends Tanjiro. Despite participating in the same Final Selection as Giyu, he lacks proven talent due to Sabito killing almost all of the demons, as well as the skill to become a Hashira like Giyu, but his determination motivates him to improve in Hashira Training, to the point he is able to defeat demons as powerful as the former Lower Ranks in the Infinity Castle. He survives the battle against Muzan and has a descendant who is a school principal.
Demons
Demons (鬼, Oni) are a race of immortal creatures that feeds on blood to survive and become stronger with each human they devour. All demons were formerly humans who lost most of their memories and traces of humanity after drinking or being injected with Muzan's blood, becoming his servants and sharing their vision and thoughts with him. Demons possess enhanced senses, regeneration, and physical abilities. Higher demons are also capable of casting powerful spells called Blood Demon Arts (血鬼術, Kekkijutsu), which are unique to each demon. Demons are weak to sunlight, which fatally turns them into ashes upon being exposed to it. They can also be killed by decapitation with special swords used by the Demon Slayers called Nichirin Swords (日輪刀, Nichirin Tō). Demons are also vulnerable to wisteria flowers, avoiding places where they are abundant and wisteria extract being poisonous to them in sufficient doses.
Muzan Kibutsuji
Muzan Kibutsuji
Muzan Kibutsuji (鬼舞辻 無惨, Kibutsuji Muzan) is the first demon, originating from a failed experimental treatment during the Heian Period. He seeks to create a demon immune to sunlight to overcome his own weakness. This goal drives him to attack the Kamado family, resulting in Nezuko's transformation. When she later develops an immunity to sunlight, he becomes obsessed with consuming her to acquire it. During the final battle, he is weakened by a composite drug that suppresses his abilities and is ultimately destroyed by sunlight. In a final act of defiance, he transforms Tanjiro into a demon to be his successor, but he is thwarted when his friends help to turn him back to a human.
Twelve Kizuki
Twelve Kizuki
The Twelve Kizuki (十二鬼月, Jūnikizuki) is a special group of demons who serve Muzan and have a special mark of their servitude 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 decides to eliminate the Lower Ranks and have only the Upper Ranks under his command.
Upper Ranks
The Upper Ranks (上弦, Jōgen) are the high-ranking members of the Twelve Kizuki, with some having mutated their bodies to the point that, unlike other demons. they cannot be killed via decapitation. Their ranks were unaltered for over a century and no Demon Slayer had managed to kill any of them prior to Tanjiro and his friends joining the organization
Kokushibo
Muzan's most powerful subordinate, who holds the title of Upper Rank One. As a human, he was a Demon Slayer named Michikatsu Tsugikuni (継国 巌勝, Tsugikuni Michikatsu) and the older twin brother of Yoriichi. Envious of his brother's talent, he became a demon to perfect himself as a swordsman without the fear of death. As a transformed Demon Slayer, Kokushibo uses a breathing style known as "Moon Breathing" (月の呼吸, Tsuki no kokyū), which is derived from Yoriichi's Sun Breathing. He dies while fighting Muichiro, Genya, Sanemi, and Gyomei, with Muichiro and Genya dying from their wounds soon after.
Doma
A nihilistic demon who holds the position of Upper Rank Two. As a human, Doma was born with unusual rainbow eyes and pale-colored hair, which caused his parents to see him as perfect and blessed, and start a religious cult centered around him. After they died, he assumed control of the cult, and, after Muzan transformed him into a demon, began eating his followers under the belief that they would live forever inside him. One member of his cult was Inosuke's mother Kotoha, whom he devoured when she attempted to flee upon learning his true nature. He was also responsible for killing Shinobu's older sister Kanae. In a desperate measure to defeat him, Shinobu administers a massive dose of wisteria-based poison in her body and allows herself to be consumed, weakening him and allowing Kanao and Inosuke to kill him.
Akaza
A contentious demon who holds the position of Upper Rank Three. He despises those he considers weak and offers those he considers strong enough to earn his respect the opportunity to become demons. As a human, he was a teenager named Hakuji (狛治) who, as a child, stole to care for his ailing father before he committed suicide to free him from the burden of caring for him. Hakuji was adopted by a martial artist, Keizo, and trained under him while falling in love with his daughter Koyuki. Hakuji's adoptive family was killed when a rival dojo poisoned them, leading him to slaughter them single-handedly, after which Muzan turned him into a demon. Akaza battles and kills Kyojuro, and later battles Tanjiro and Giyu in the Infinity Castle, during which he regains his human memories and commits suicide by destroying his body and ceasing his regeneration, dying of his wounds.
Hantengu
A cowardly demon who holds the position of Upper Rank Four. Hantengu shows his true strength upon dividing himself into multiple clones which denote different emotions, each one possessing a unique appearance, personality, and ability: Sekido (anger), Karaku (pleasure), Aizetsu (sadness), Urogi (joy), Zohakuten (hatred), and Urami (resentment). As a human, he was a prolific criminal who boasted of his innocence despite his conviction before Muzan turned him into a demon. He attacks the Swordsmith Village with Gyokko, where Tanjiro, Nezuko, Genya, and Mitsuri confront him. Tanjiro kills him, but he lives long enough to inform Muzan of Nezuko's newfound immunity to sunlight.
Nakime
A biwa-playing demon who owns the Infinity Castle (異空間無限城, Ikūkan Mugen-jō), an alternate dimensional space that Muzan made his base of operations. As a human, she was a struggling musician who developed a habit of murdering prior to her performances, as she associated killing with applause. 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 becomes Upper Rank Four after Hantengu's death and later confronts Mitsuri and Obanai until Yushiro restrains her, prompting Muzan to kill her to stop him from controlling the castle.
Gyokko
An arrogant demon holds the position of Upper Rank Five. Unlike the others, Gyokko has a highly distorted djinn-like anatomy with his eyes being on his forehead and mouth along with two mouths being where his eyes would be. As a human, he was an ostracized villager who developed an obsession with corpses after his parents drowned at sea and their bodies washed up on shore. He kidnapped and killed a child before being stabbed and left for dead, after which Muzan transformed him into a demon. He claims himself to be an artist and takes pride in his creations, including twisting his victims' bodies into grotesque, living sculptures. He attacks the Swordsmith Village alongside Hantengu but is killed by Muichiro.
Daki
A petulant demon who shares the position of Upper Rank Six with her older brother Gyutaro. Daki takes advantage of her work as an oiran in the red-light district to attract victims. As a human, she was named Ume (梅; lit. syphilis), after the disease that killed her mother, and was raised by Gyutaro in the district slums they were born in. Her beauty led to success in the district at a young age, until she was burned alive at the age of thirteen by a customer she attacked. She was on the verge of dying alongside Gyutaro when Doma — who was Upper Rank Six demon then — transformed her into a demon and introduced them to the Twelve Kizuki. She wields an obi belt made of her flesh, which she also uses to absorb her victims and place them in a secret location before devouring them. After Zenitsu and Inosuke kill her, she returns to her former human appearance and meets Gyutaro in the afterlife, refusing to leave his side despite him trying to push her away so she would not have to go to Hell, reminding him of their promise to survive anything together.
Gyutaro
A misanthropic demon who shares the position of Upper Rank Six with his younger sister Daki. As a human, he was born in the red-light district slums alongside Daki and was ostracized for his unsightly appearance. Ume 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 the customer who burned her alive; Doma later turned him into a demon. He usually hides within Daki's body and emerges whenever her life is threatened. He fights using his poisonous blood and two flesh sickles as his Blood Demon Art. As dual holders of Upper Rank Six, Gyutaro must be decapitated together with Daki to be truly killed. After Tengen and Tanjiro kill him, he expresses regret over being a negative influence to Ume when she was alive and decides to go to Hell alone to atone for their sins, but he relents after Ume refuses to leave his side.
Kaigaku
A young demon who becomes the new Upper Rank Six following Daki and Gyutaro's deaths. As a human, he was one of the orphans under Gyomei's care; he was chased out by the other children for stealing the temple's money and encountered a demon, which he let into the temple in exchange for having his life spared, leading to their deaths and Gyomei's wrongful imprisonment. He then became a member of the Demon Slayer Corps, learning the Thunder Breathing style from Jigoro along with Zenitsu, before betraying them and allowing Kokushibo to transform him into a demon, leading Jigoro to commit seppuku in atonement. Unlike Zenitsu, who only mastered the first of the six forms of Thunder Breathing, Kaigaku only mastered the other five. He battles Zenitsu but is killed when Zenitsu strikes him with a self-taught, seventh form.
Lower Ranks
The Lower Ranks (下弦, Kagen) of the Twelve Kizuki, whose membership is constantly shifting compared to the Upper Ranks. Following Rui's death, Muzan kills all of them except for Emmu for being worthless to his plans.
Enmu
The Upper Ranks (上弦, Jōgen) are the high-ranking members of the Twelve Kizuki, with some having mutated their bodies to the point that, unlike other demons. They cannot be killed via decapitation. Their ranks were unaltered for over a century and no Demon Slayer had managed to kill any of them prior to Tanjiro and his friends joining the organization.
Rui
A child-like demon who holds the position of Lower Rank Five. As a human, he was a sickly boy who was transformed by Muzan. He killed his parents in self-defense when they attempted to kill him out of atonement; the ordeal caused Rui to forget his human memories. Being a favoured member of the Twelve Kizuki, he gains Muzan's permission to transform other humans and demons with his blood into a replacement family, who he abuses due to his warped view of familial bonds. This causes him to be envious of the Kamado siblings' bond, as he loses his calm demeanor and attacks erratically until Giyu kills him. In his final moments, he remembers his parents and reunites with them in Hell.
Kyogai
A demon and former Lower Rank Six of the Twelve Kizuki. He is known as the "Drum Demon" (鼓鬼, Tsuzumi Oni). After Muzan strips him of his rank due to slowly losing the ability to eat humans and reaching his limit, he obsessively tries to earn his spot back in the Twelve Kizuki, attacking and eating humans who pass by the Tsuzumi Mansion. He fights using the tsuzumi drums embedded into his body; striking them can change the house's rooms around as well as his position in it, and also allows him to unleash powerful air slashes. Following an arduous battle, Tanjiro kills him.
Kamanue
A demon who holds the position of Lower Rank Six. He is the first member of the Lower Ranks that Muzan kills when he decides to purge the Lower Ranks after he questions his expectations, which Muzan sees as defiance.
Mukago
A demon who holds the position of Lower Rank Four. Muzan kills her after deducing that she was more afraid of the Demon Slayers than him and interpreted her attempt at saving face as contradicting him.
Wakuraba
A demon who holds the position of Lower Rank Three. Muzan kills him when he tries to escape the Infinity Castle.
Rokuro
A demon who holds the position of Lower Rank Two. He is killed when he asks Muzan for his blood to gain strength and fight for him, which Muzan saw as undermining his authority.
