Ah! Itoshi No Banchousama. Souka is moving with her newly divorced mother to a new place to live. Souka wants to leave her preppy, private high school behind while searching for a school to enroll while and moves to a technical high school. To her shock, she is the only schoolgirl grad! The first school day is nothing like she'd ever imagined — boys bursting through the window, fighting for all they're worth. One day, Souka is ambushed by the school's new "Bancho" (a term for a gang leader). Yu, one of the classmates, determined to protect her, comes to her rescue but Yu ends up in a fight. Souka's trying to help swings her book bag and ends up pushing the Bancho herself down! What Souka didn't know was that you've become the leader of the class when someone brings down the leader of the class. It wasn't a job she planned for herself, but she can give it up?
