Battle with a beautiful exorcist girl with black jack!
If you can beat them, you can see them falling into the pleasure world!

Magic seal have been expired, and many monsters are walking around in this world.

One day, a monster stepped into its door of the school.

He is a half human and half a monster, trying to prove his power to the Damon king by battling with those beautiful exorcists, humiliate them and make them obey him.
