Monster Musume v01-v13 (2013-2018)

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, like the Interspecies Cultural Exchange Accord!
When twenty-something Kurusu Kimihito becomes an involuntary "volunteer" in the government homestay program for monster girls, his world is turned upside down. A lamia named Miia is sent to live with him, and it's Kimihito's job to make sure the sexy snake girl integrates into everyday life. While cold-blooded Miia is hot for Kimihito, the penalties for interspecies breeding are dire. Even worse, when a buxom centaur girl, and a scantily-clad harpy move into Kimihito's house, what's a full-blooded young man with raging hormones to do?
