When Shuichiro rescues an angel, he's granted a single wish. The problem is, Shuichiro can't think of any wishes that he can't grant himself. The angel, Amber, refuses to leave Shuichiro without granting a wish, so she moves in with the young doctor and helps out around the house, waiting for a chance to return the favor. Of course, angels aren't the only supernatural beings wandering the Earth. Soon demons and archangets alike are stopping by Shuichiro's house, making things difficult for his angelic roommate.
