Kanojo ga Kawaii Sugite Ubaenai

As one of the seven demon princes of Hell, Shion strives to become the next demon king by passing the Demon King Succession Exam. However, unlike in previous years that required the princes to steal a human soul, Shion's new objective is to steal his designated human's heart—to be more exact, her virginity. A romantic-gag comedy between two virgins is about to unfold.
