Seishun Buta Yarou wa Bunny Girl Senpai no Yume wo Minai

It is believed that the uncommon and mysterious Puberty Syndrome is a myth. It is a rare sickness that exclusively affects youth, and because it only manifests as supernatural occurrences, very few people are aware of it. However, Sakuta Azusagawa, a high school student, is aware from personal experience that it is very much genuine and is extremely common in his school. Third-year high school student Mai Sakurajima first earned notoriety as a child actress, but she just ended her promising career for reasons that the general public is not aware of. She has a reputation for being distant and is well-known across the school, but nobody dared approach her until Sakuta spotted her pacing the library in a bunny girl costume. Despite her attire, nobody seems to pay attention to her, and when he does, he discovers that she is another sufferer of puberty syndrome. Sakuta comes into contact with additional ladies who have the illusive disease as he tries to assist Mai through her situation.
