Otoboku: Maidens are Falling for Me

Mizuho can't believe his ears when Grandpa's will is read out. Grandpa's final wish is for Mizuho to attend the same academy as Mizuho's mother. The catch is it's an all-girls school. With the help of his friend Mariya however, he gets a makeover good enough to fool everyone at the academy.

Two years after Mizuho's graduation... Mikado Chihaya was truant at his school because of harassment in the school and of a distrust in men. His mother cannot bear to watch him be in trouble, so she makes him transfer to Seio Girls' School, her old school. He dresses as a girl and introduces himself as Kisakinomiya Chihaya. Chihaya meets Nanahara Kaoruko, who once rescued him from a playboy, and he begins to live in the dormitory building. He becomes the focus of public attention due to his attractive face and figure, and due to high grades at studies.
