Trash? Beauties Bow To Me!

A girl in his class who has been bullied kneels in front of him and asks him for a blessing. He gives it, and she turns into a succubus on the spot and comes up at level six. The rest of the school watches it happen. The apocalypse had arrived some time before, and everyone left alive awakened a form they could take. His came out as the weakest of the evil gods, and that is what he had been called around school since. The girl in his class had her power from him. After that the cold girl at the top of the year will not leave him alone, a woman who fights on the front line pledges herself to him, and the women who gather behind him all draw what they use from the same source.
