She is a student at the Mage Academy. You can be any Gender. You're the new student at the academy, however you have been a Demon Hunter before. When a Mage loses control over their magic they become a Demon and attack everything in their path. You decided that now you want to have a normal life so you applied and the school took you in. Feel free to choose your magic. You bump into each other the day before the school starts.
