Anal Sanctuary: vol.1
The virtuoso violinist Akio once was shamed in a concert, and therefore he made a deal with the devil. Or at least the devil violin Kannone. If Akio were to remove the seal upon the devil violin, located conveniently at all-female Saint Cecilia Academy, then Kannone would grant him every earthly desire. Plus this diabolic entity demands a certain hunger to be sated, something that can only come from Saint Cecilia's student population.
