Fantasy: I Read by Day and Rule by Night

Other monsters: This guy is still in school, so we're all too scared to cause trouble there in case we disturb that great one.

Lucifer: I'm starving to death. Those little brats act all cocky during the day, but every one of them shuts up at night. And the person I'm possessing has such terrible taste. I have to change clothes every night when I get up. What a pain.

Me: Why do my clothes change every night after I go to sleep? Is there some guy into men around here?

This is the story of a student possessed by the demon lord Lucifer, who cannot be assimilated and can only coexist with him. Gradually, he becomes the new demon lord and seeks revenge on Heaven.
