What do world governments do when they learn that fantastical beings are not merely fiction, but flesh and blood —not to mention feather, hoof, and fang? Why, they create new regulations, of course! “The Interspecies Cultural Exchange Accord” ensures that these once-mythical creatures assimilate into human society...or else!

When hapless human twenty-something Kurusu Kimihito becomes an involuntary “volunteer” in the government homestay program for monster girls, his world is turned upside down. A reptilian lamia named Miia is sent to live with him, and it is Kimihito’s job to tend to her every need and make sure she integrates into his everyday life. While cold-blooded Miia is so sexy she makes Kimihito’s blood boil with desire, the penalties for interspecies breeding are dire.

Even worse, when a buxom centaur girl named Centorea and a scantily clad harpy named Papi move into Kimihito’s house, what’s a full-blooded young man with raging hormones to do?!
