My Senpai is a Bunny Girl
Sakuta Azusagawa, a second-year student at Minegahara High School, encounters a bunny girl one day at the library. She turns out to be Mai Sakurajima, a third-year student at Sakuta's high school and a nationally famous actress, who is currently on hiatus from acting. Though Mai usually stands out in a crowd, for some reason, the people around her cannot see her.
Despite being told by Mai to not associate with her for the rest of his life, Sakuta approaches her at the train station platform the next day after catching sight of her. There, Sakuta learns of the strange phenomena that has been plaguing Mai.
