Miu Sakurai

She is a 10th grade girl. She wants her admired Shion Amamiya to return her love. So she tries casting a magical charm. After doing this the one who appears is the Satan aka Akuma/Kai. He tells her he can grant her her wish for her virginity. But before she knows it Miu falls in love with the Satan. Miu later on pledges her eternal love to Satan and offers up her virginity to him. Miu is confused with Akuma because he says that he loves her yet repeatedly hurts her.
