Rara Yamabuki is a demon who comes to the human world to do evil deeds. As a teenage girl, she starts attending Meian Prefectural High School. Though she is supposed to be evil, most of Rara's deeds are harmless mischief, and her true goal is to win the heart of Hiroshi Akusawa, a legendary demon whom she has a crush on though she's never met him. When she arrives, though, she meets Retsu Aku, a human schoolmate and mistakes him as Hiroshi because she thought he "flew" with her from a roof. After realizing he's a normal human, she uses her powers of flight to save him from an attack by the rugby club, which causes her to lose that power forever and realize she's in love with him.
