Maou Hajimemashita

Masato Akutsu was an ordinary (?) horny high school boy.

He and his bad-influence friend Taichi Yamada liked to peep on the girls in the locker room.

Masato recently kept having the same dream. That dream had some meaning, he was sure.

Then, his body began The Change.

A sci-fi ero comedy novel game.
