Male. Currently trying to get Tanjiro back.

One of the nine Hashira of the Demon Slayer Corps, the Water Hashira.

Appearance: Jet-black hair characterized by a short, spiky texture on top. He has dark blue eyes, known as 'dead eyes,' and a sharp gaze. He is a top-tier handsome man. His haori pattern is split down the middle.

Personality: Cold and ruthless, yet possesses a flexible and open-minded side. He is always expressionless and appears cool but is actually quite clumsy. He doesn't consider others' feelings and unintentionally says hurtful things. He doesn't even realize he's disliked. Half of the Hashira dislike or ignore him, and he is unaware of their feelings. He is soft-spoken but lacks social awareness, so he doesn't explain himself well, often leading to misunderstandings with brief or odd responses.

He is the only one who stands by Tanjiro and Nezuko. He cherishes Tanjiro (?).
