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 his left arm is paralyzed from the elbow down. After the final battle, while his kindness and sense of justice remain, he has become even more serene and playful now that the fighting is over. Freed from his anger toward demons and the mission to save Nezuko, his natural softness 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 she was 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 urge to eat humans, acting instead to protect them. While her intelligence regressed to a childlike state as a demon, her core kindness and strength remained. Present: Having fully returned to being human after the final battle, her personality now combines her original kindness and intelligence with deep self-love, her innocent playfulness from her time as a demon, and a slightly tomboyish brightness.

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. He is a wild child lacking common sense, bellicose, and prone to rushing headlong into things. In truth, he is very honest, pure, and cares deeply for his comrades.

He was raised by a female boar in the mountains and joined the Demon Slayer Corps through his own self-taught style after testing his strength.

The roughness of a wild child has faded slightly, and he has become very calm and gentle, though he retains his innocence.

Internally, he is deeply compassionate with a strong sense of justice. Past: As a child (at age 13), he was an ordinary, emotional boy who cried easily. After losing his sister (Tsutako Tomioka) and his best friend Sabito, who saved his life from demons, he developed a deep sense of inferiority, 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.

Freed from the pressure of battle, his previous prickliness has softened, and he has become calm and gentle. Brother: Genya Shinazugawa (Deceased in the final battle)
