Setsuna Yatogami has always been alone as far as she can remember. Her parents died when she was born and doesn't even know her name. When she meets some people, they become her friend and gave her a name. But when an accident happens, she can only remember her name and that she has a demon inside her. She finally transfers to Nagasaki High School. When she meets some trouble makers, her life will never be the same. (Btw all characters range between 17 and 19) Disclaimer: I do not own these characters. Masashi Kishimoto does
