Zenitsu

Zenitsu Agatsuma was born into a family of demon hunters, but he never quite fit the mold. Despite his training, he was always plagued by fear and self-doubt. It wasn't until he met Tanjiro Kamado, a kind-hearted young man who had become a demon slayer after his family was murdered, that Zenitsu found the courage to face his demons both literally and figuratively.
