Mero the mermaid is actually the daughter of the king and queen of the sea, and now her royal mother is summoning her back home. Kimihito, along with the other monster girls living in his household, go to visit the mermaid queen in the hopes of changing her mind. Along the way, they uncover a tangled scheme that involves kidnapping, royal intrigue, tragedy, and, of course, naughty tentacles. If this intrepid group can manage to stay un-molested long enough to solve the mystery, they could transform the entire mermaid kingdom! But for once, Kimihito isn't the only one risking his life in the name of interspecies relations.

Kimihito's eyes are about to pop. The mothers of not one, not two, but three of the monster girls who live with him are coming for a visit. It doesn't help that this trio of mothers is every bit of sexy as their daughters - and just as dangerous to Kimihito's mental and physical well-being. Stuck in the middle between the mothers and their daughters, Kimihito learns more than he ever wanted to know about the mating habits of lamia, harpies, and centaurs, while repeatedly facing the possibility of an ecstatically painful death. Fur, feathers, and scales are about to fly, as Kimihito's hide hangs in the balance!

Get married and I kill you. This was the letter sent to Kimihito, an ordinary guy living with a houseful of extraordinary beauties, by a mysterious writer known only as "D." Now it's up to Interspecies Coordinator Smith, Kimihito, and his ever-increasing menagerie of monster girls to find out who is behind the threatening letter before it's too late. The game plan? Use Kimihito as bait by sending him on a series of dates with monster girls. Along the way, several possible suspects emerge, each of whom has a "D" connection of one kind or another. Meanwhile, Kimihito's potential brides each begin acting strangely. Are they taking the fake dates too seriously - or is something (or someone) far more sinister at work?

So far, Kimihito's been lucky. The monster girls living with him have been cute, curvaceous, and have never tried to kill him on purpose. But now, the dark side of liminals rises to the surface. Piggish orcs run hog-wild over Japan to satisfy their perverted desires. And the team that the government assembles to combat them is every bit as strange and inhuman as the criminals they're fighting. Meanwhile, Kimihito has to contend with adding the lovely and elegant mermaid Mero to his ever-growing menagerie of monster girls. How will the possessive Miia, the noble Centorea, the bird-brained Papi, and the slime-girl Suu react to the newest addition to their household - and yet another contender for Kimihito's heart?
