With Japan having developed as a maritime nation, it became necessary to have specialized schools to teach skills essential to protecting the sea. The setting is one such all-girls school. The girls who enroll here study to become "blue mermaids," through classroom instruction and teaching of practical skills. "Blue mermaids" are women who pursue the ocean for their professional occupation. They live by the motto "In the sea we live, the sea we protect, and by the sea we go." They must excel in their studies, but must also adopt an international mindset. They are the "Elite of the Sea," and are expected to be knowledgeable of the customs and cultures of other countries as well as their own.

Monsters-they're real, and they want to date us! Three years ago, the world learned that harpies, centaurs, catgirls, and all manners of fabulous creatures are not merely fiction; they are flesh and blood-not to mention scale, feather, horn, and fang. Thanks to the "Cultural Exchange Between Species Act," these once-mythical creatures have assimilated into society, or at least, they're trying. When a hapless human named Kurusu Kimihito is inducted as a "volunteer" into the government exchange program, his world is turned upside down. A snake-like lamia named Miia comes to live with him, and it is Kurusu's job to take care of her and make sure she integrates into his everyday life. Unfortunately for Kurusu, Miia is undeniably sexy, and the law against interspecies breeding is very strict. Even worse, when a ravishing centaur girl and a flirtatious harpy move in, what's a full-blooded young man with raging hormones to do?!
