Tsukiko Amatsuki is the president of the school's animal care club. Even though she's the only member, while she's diligently tending to the animals, a beautiful girl suddenly calls out to her! "Take care of me." The self-proclaimed exchange student Yosefka says she's having trouble in this unfamiliar land...? "Humans are animals too," she declares, and just like that Tsukiko ends up looking after her — even teaching her how to use the toilet!? "I want breast milk." "I want to have intercourse." Even though her word choices seem rather suspicious for an exchange student, before she knows it Tsukiko has to take care of her every need — from meals to studying — hand and foot. A chaotic, pervy comedy about the animal care club president Tsukiko and the exchange student (?) Yosefka!!

The only human student at an all-girl school is on a mission to sexually harass each of the monster girls.

Lilya, whose self-awareness has awakened, is not innocent and pure—but rather intensely curious about sex!? Lilya, a non-human being who has gained "heart" and "life" from her host, suddenly awakens to "sex" one day, having just gained self-awareness. "Where do babies come from?" She sneaks into school, letting her imagination run wild, and learns (mistaken?) knowledge about sex—!?
