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! Which girl would you choose?
In present times, Gods and Demons coexist together with Humans after the door between each of these worlds had opened. Tsuchimi Rin is a normal young high school student attending Verbena Academy, spending his days living peacefully with his childhood friend Kaede. Unexpectedly, one day the King of Gods, the King of Demons and their families move into be Rin’s next door neighbors. Apparently the daughter of the Gods, Sia, and the daughter of the demons, Nerine, are both deeply in love with Rin after having met him in the past. Along with his playful friendship with upperclassmen Asa and his encounter with the silent but cute Primula, Rin has much on his hands dealing with the affections of each of these girls. Based on the eroge by Navel.
Kaede is a devoted high school student who lives with her adopted brother Rin. She holds a quiet confidence that one day, when Rin finally starts showing interest in sex, he will make the obvious choice and turn to his loving sister. But what Kaede wasn’t counting on was the lords of heaven and hell coming to Earth, wanting Rin to mate with their nubile daughters! Rin, like any teenager would, takes full advantage of his newly acquired harem; but how long can he keep up his carefree, boxed-lunches-on-the-rooftop lifestyle, as the horde of girls on his tail grows?
