When Gavin finds that a catgirl from another world mysteriously appears in his pantry, he decides, against all logic, to let her live in his room. But it's not easy to keep a curious, free-spirited catgirl a secret. She doesn't know anything about Earth culture, she's constantly bored, and she has a strange and frustrating disregard for clothing. It'll be hard enough for Gavin to keep his parents from finding out. And it'll only get more complicated once a shadowy organization bent on killing any otherworlders enters the scene... An ecchi reverse-isekai romance adventure involving a catgirl. Strong sexual themes and frequent nudity, but no explicit descriptions of sexual acts (i.e. not erotica).
