It's about this kid who eats demons.
The setting is olden japan, with dynasties and no technology. This boy, Qwan, eats demons instead of food. He doesn't quite know why he is on earth (because he isn't a normal person and thinks he is from heaven) So he goes off to find the "Scroll of Peace" hoping it will give him answers as to why he is on earth.
So far, that's as far as I've gotten in the stories.
