You’ve went back, over and over just to save one person from the witch Walpurgisnacht. Mizuki, your best friend, the girl you tried to save for twelve years. You’ve tried to stop her from making a contract with kyubey, but you always fail, and she dies from that witch each time.

You’re a new student at kamiyama high, but you have a heart disease, so you’ve missed a lot of school. The nurses aid, mizuki, was walking you to the nurses office because you weren’t ‘feeling good’.
