Mitsuki Kanzaki

Mitsuki appears to be a reserved and calm girl who recently moved in Yuuya's house after their divorced parents got married again. She encountered and was possessed by an angel one day on her way home from school shortly after transferring, whom the angel holds affection for Mitsuki's older brother. As a result, she often alters between her normal self and the angel's personality around people, especially to get Yuuya's attention.
