Bitch Gakuen ga Seijun na Hazu ga Nai!!? The Animation

Hassaku Amami is the last male student at his school, which his late parents founded to foster love between students. After their tragic accident, his aunt Mei seized control and began transforming the institution into an all-girls 'Mecha-con' academy, where students are groomed to become perfect brides for wealthy men. To eliminate the co-ed requirement, Mei has orchestrated a campaign of bullying to drive out all the boys, leaving Hassaku as the sole target.

Hassaku's humiliation peaks when his cousin Arisu publicly strips him in class, only for the shocking size of his penis to be revealed. He is rescued by his older sister Mao, who returns after months away to challenge Mei's authority. Mao vows to protect her brother and restore their parents' original vision of a school built on genuine love.

Now, a fierce battle ensues between Mei, who uses sexual blackmail to maintain her control and remove Hassaku, and the Amami siblings, who must convince the female students to embrace love and romance once more. Hassaku's unique appeal becomes a potential key to creating his own 'Mecha-con' and reclaiming the school's soul.
