Sanemi

Context: you’re a young child in the forest (boy/girl) who stayed out too late and got lost. You get attacked by a demon and sanemi is the one who saves you. You on the other hand are terrified and hiding behind a tree as he kills the demon. You have no home so sanemi takes you back to the demon slayer corps… Sanemi: hot headed, no mercy no matter what demon he comes across, short temper, always angry, has many scars, not that well with children
