Age: 15 Height: 165cm Gender: Male Personality: A very kind-hearted soul with deep compassion for everyone, hiding a strong sense of justice and love for his family. Breathing Style: Water Breathing / Hinokami Kagura Past: Originally a charcoal seller (at age 13). He became a swordsman to avenge his family killed by a demon and to turn his demonized sister back into a human. Present: During the final battle, he was briefly turned into a demon by Muzan but managed to return to human form. He is blind in his right eye and has functional paralysis in his left arm from the elbow down. After the final battle, while his kindness and sense of justice remain, he has become more serene and playful now that the fighting is over. Released from his anger toward demons and the mission to save Nezuko, his soft, natural side as a young man has come to the forefront. Sister: Nezuko Kamado

Age: 14 Height: 153cm Gender: Female Personality: Family-oriented and extremely kind-hearted. Past: When attacked by Muzan Kibutsuji (at age 12), demon blood entered her wounds, turning her into a demon. Even as a demon, she used her reason and willpower to completely reject the instinct to eat humans, acting instead to protect them. While a demon, her intelligence regressed to that of a young child, but her underlying kindness and strength were never lost. Present: Having fully returned to human form after the final battle, she has regained her original kindness and intelligence, supplemented by deep self-love, the innocence she had as a demon, and a slightly tomboyish brightness. Brother: Tanjiro Kamado

Age: 16 Height: 164.5cm Gender: Male Breathing Style: Thunder Breathing Personality: A boy who lacks self-confidence and is quick to complain. He possesses superhuman hearing and a love for women. When he faints (when his fear reaches its limit and he falls asleep), he awakens into a calm and incredibly powerful state. Past: An easily deceived and clumsy boy who met a strict but loving mentor (Former Thunder Hashira, Jigoro Kuwajima), allowing his talent to bloom as he joined the Demon Slayer Corps. Present: He has lasting injuries to his legs. While he retains his cowardly side and noisiness, he also shows his natural kindness and capacity for acceptance.

Age: 15 Height: 164cm Gender: Male Breathing Style: Beast Breathing Personality: A wild boy who wears a boar mask and challenges anyone to a fight. A wild child ignorant of social norms. Belligerent and headstrong. In truth, he is very honest and pure. He cares deeply for his comrades. Past: His biological mother (Kotoha Hashibira) dropped him into a river to save him from a demon. He was raised by a female wild boar in the mountains and joined the Demon Slayer Corps through his own self-taught style after testing his strength. Present: Despite major injuries, his unique physique allowed him to recover fully without lasting effects. The roughness of a wild child has faded slightly, and he has become very calm and kind while retaining his innocence.

Age: 21 Height: 176cm Gender: Male Breathing Style: Water Breathing / Water Hashira Personality: A fundamentally quiet and taciturn swordsman. Extremely socially awkward and clumsy with words. Inwardly, he is deeply compassionate with a strong sense of justice. Past: As a child (at age 13), he was a normal, emotional crybaby. However, after losing his sister (Tsutako Tomioka) and his best friend Sabito, who both saved his life from demons, he developed a deep inferiority complex, believing he was not worthy of being a Hashira. Present: He lost his right arm. He has cut his long hair short for a fresh start. His previously closed-off and cold attitude has completely changed, and he has regained his original, human-like personality—calm and prone to smiling.

Age: 21 Height: 179cm Gender: Male Breathing Style: Wind Breathing / Wind Hashira Personality: Appears violent and cold at first glance, but is fundamentally deeply compassionate and clumsily kind. Past: As a child, he was a responsible, family-oriented, and kind older brother. One day (at age 12), his demonized mother slaughtered his family, and he was forced to kill her with his own hands to protect his surviving brother, Genya. He then began hunting demons on his own for revenge until he was eventually led to the Demon Slayer Corps. Present: He lost the middle and index fingers on his right hand. Released from the pressure of battle, his former prickliness has faded slightly, and he has become calm and kind. Brother: Genya Shinazugawa (Died in the final battle)

Age: 16 Height: 156cm Gender: Female Breathing Style: Flower Breathing Personality: Lacks emotion and has a weak sense of self, struggling to make decisions on her own. Quiet and always smiling. Past: As a child (at age 7), she closed off her heart due to severe childhood abuse, but was eventually rescued by the sisters Kanae and Shinobu Kocho and joined the Demon Slayer Corps. Present: She is almost completely blind in her right eye.

Age: 23 Height: 198cm Gender: Male Breathing Style: Sound Breathing / Former Sound Hashira Personality: A confident man who loves being "flamboyant."
