Iofiel is an ideal candidate to become a guardian angel, and help steer humans away from sin: she's helpful, cheery, and utterly loyal. And, as the 'angel of beauty', it's not like she has anything better to do. Heaven and Hell long ago ran out of space: there's too many humans these days, so both have come to a shaky truce– one school hidden in the forests of Canada, hidden from humanity, where their best and brightest can study. All seems well for Iofiel's first days at university– her archangel roommate is a bit uptight, and dealing with demons feels weird– but when a picked on demon confesses he's too nervous to pursue his true passion of soul stealing... Iofiel promises she'll major in it with him! So much for being a proper angel. Her helpful impulse has repercussions that shake the school, and may just change the world forever. Or maybe just end it. Because that's a possibility too.
