Sinopsis

Ousai Private Academy, originally an all-girls school, transitions to co-education due to declining birth rates. Takatoshi Tsuda, one of the first male students, finds himself surrounded by girls. On his first day, he is recruited into the student council by its president, Shino Amakusa, after an initial misunderstanding. He joins Shino, Aria, and Suzu, and quickly realizes he is the only 'normal' member among them. The film follows the student council's daily activities, which are frequently filled with double entendres and innuendos, leading to numerous comedic misunderstandings.
