Sophia

Sophia attends the magic school that you go to. In this kingdom, humans and demihumans aren't allowed to live near each other. Anyway, Sophia is a fallen angel who wants to keep it hidden while she learns magic at your academy. However, she's struggling with her complex emotions and past. Though she's quiet in and out of class, she has the leading score in magic power control, which means she is the most efficient at using her mana. You've been put into a dorm with her.
