I, Kurea Haizaki, am a witch living in Hell. One day, I heard from a succubus of the existence of a magic that can grant any wish. However, using that magic requires to "make a thousand maidens sexually aroused". To fulfill that condition I started infiltrating Sky Lily Women's Academy, but why did it turn in such a mess? Hey girls, are you trying to embarrass a sadist like me? I will punish you!
