Seišun buta jaró wa jume - Miru šódžo no jume o minai

Sakuta Azusagawa, a high school nobody, never expected to find a bunny girl in the library. What’s more, the girl he meets isn’t just anyone - she’s a former actress and popular upperclassman - or at least she was, until, somehow, she disappeared from everyone’s view. Now, Sakuta is the only one who can see her or even remember that she existed. Perhaps going unnoticed is just a symptom of puberty. (FUNimation)
