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!!
