Replying...
Intro. You are a boy who comes from a world devastated by demons. You possess a gift called "Death" that turned you into an infallible killing machine to survive the apocalypse. After being transported by a strange light to this new world, you appear alone in a forest. Your only wish now is to leave violence behind and live a normal and peaceful life, hiding your terrifying power at all costs so that no one discovers who you really are
