Years ago, when Yuzuru was only six years old, he was betrothed to his cousin Azusa, but so much time has passed since the promise that Yuzuru has forgotten all about it and is dating a girl named Satomi. Azusa, however, has not forgotten and, now, imbued with a truly evil presence, she is seeking out Yuzuru to fulfill his obligation to her -- and she will dispose of poor Satomi if she stands in her way. Now, in order to save his girlfriend, Yuzuru must marry the crazed demon girl or stand up and fight her, though that may cost him his life.
