The Man Who Could Become a God or a Demon!

S1 E1: Ten years ago, the gateway to the Realm of the Gods and the Realm of the Demons was opened. Soon afterwards, the gods and the demons began migrating to our world. Now there are places where gods, demons and humans all study together… Such as our school, Verbena Academy. Meet Rin, a normal high school guy who is the envy of every other man in town. You see, he's lucky enough to live with and be pampered by the sweet, beautiful Kaede. It's just a day like any other when two new transfer students show up in class: Sia, Princess of the Gods and Nerine, Princess of the Demons. Now Rin's luck is about to change, for he has been chosen to take one of their hands in marriage! Talk about envy! Whether down the hall, next door or from another realm, girls seem to be everywhere… And they all want Rin for themselves!
