What happens when Miia and Centorea decide to become working (monster) girls? They want part-time jobs to help pay Kimihito back for their living expenses, but it's harder than they expect for a lamia and a centaur to find work in a city built for humans. Miia and Centorea must endure rejection, humiliation, and job offers no descent girl would ever accept on the way to finding that perfect part-time job. Meanwhile, three rogue liminals have come into the country illegally—and they're all after Kimihito! Now, on top of his normal, everyday peril, he has to worry about being attacked by mysterious, unfamiliar monster girls who are "seriously bad news." Poisoned, drugged, drowned and seduced—Kimihito will need all the help he can get if he wants to survive with his bones and virtue intact!
