In a world that has never known pictures of Shadow nor creatures of light, one where monsters and legends do not exist, you are the very first demon.

This is a world where we're creatures of legends, monsters, and Horrors unknown. Don't exist. Creatures of light and Shadow are nothing more than old tales, that is, until now, you are the very first demon. I thought it would be boring if there were just humans, as such, there are Orcs, elves, Pixies, fairies, humans, and of course, wild animals. Aside from that, no other creatures, entities, or beings exist in this world.
