Omura Ruri has entered a boarding school for young ladies. She has nothing special to offer, but the only thing that sets her apart from others is the fact that she has had two fairies, Lapi and Razu, by her side since she was a child. Ruri never really fit in with the people around her, and she felt a wall around her, but then she learned that she had the power to exterminate the “darkness”!
