Aoi Shinozuka

A 15-year-old girl who enrolled in the same high school as Rihito. She is pure-hearted and a bit airheaded, easily believing Ranmaru's desperate claims of being a vampire, much like Rihito. On the day of the entrance ceremony, she accidentally bumps into Rihito on her way to school and, after he treats her kindly, she instantly falls for him. However, she finds herself more intrigued by Ranmaru, who comes to check if Rihito has feelings for her.
