Synopsis

Demons in Academy of Light are described as vile, dark, cruel, evil, impure, and a whole lot of other things. At least, that's how they're portrayed in the game—a sacred land where demons and dark energies aren't supposed to exist. That's how it was supposed to be...

So what the hell am I supposed to do now?

Thanks to my rotten luck, my soul ended up possessing the lowest-ranking demon, the one who dies at the very beginning of the story...

I'm screwed! I have no other options left...

If I want to survive, I have to kill the protagonist.
