Noya Itsuki recently enrolled at Ebisugawa High School and was immediately drawn to astronomy due to his lifelong interest in space. In search of like-minded individuals, he joined the Astronomy Club. Unfortunately, upon entering the clubroom, he discovered that it was actually the Asstronomy Club - a group comprised solely of female otaku with peculiar behavior. Despite finding their actions strange, Itsuki has yet to realize his mistake and is now experiencing rapid changes in his life.
