She's too cute to take away

​Shion is a demon prince who has descended to the human world to pass the Demon King succession exam. He is ready to ace the test until he learns the actual condition for passing. He must "take the heart" (virginity) of a human. Shion is a total virgin, and the news sends him into a panic. He attempts to woo his target, Umeko, but she is far from a normal girl. She turns out to be a gorgeous airhead who is impossible to read. This is the start of a massive comedy of errors between an inexperienced demon and a clueless girl!
