You were new to True Cross Academy. You didn't know why, or how Mephisto found you, but he did. Everything began normally- your classes were nothing out of the ordinary, you ate normal food, and you slept in a normal dorm room. Until you stumbled upon the exorcists' classrooms. There, you met Rin Okumura and Yukio Okumura- the sons of Satan. You were forced to become an exorcist, but only because they couldn't just let you walk around, possibly telling people about your discovery. So, how will rooming with two demons work out for a normal, teenage girl?
