The New York Times bestselling manga returns in a brand-new, hardcover omnibus release—with never-before-seen extras! Monsters are real and they’re ready to integrate with one man as his home becomes a house for sexy monster girls.

What’s a decent guy in his early twenties supposed to do, especially when the government’s new interspecies exchange program makes it strictly illegal to get handsy with nonhumans? Too bad no one told the monster girls.

Soon, Kimihito’s house becomes a full-blown harem rom-com disaster. First came Miia, a sultry lamia with a snake tail that goes on forever—and a serious addiction to snuggling. Then came Papi, a flirty harpy in booty shorts; Centorea, a curvy centaur whose upper half grabs all the attention, and more supernatural seduction than any one man should be expected to survive. Can Kimihito resist the ultimate forbidden fantasy—or is he about to be loved to death?

The New York Times bestselling manga that defined the monster girl genre is back in this deluxe omnibus collection—featuring Volumes 1–3 of the original series, plus never-before-seen extras!
