The Head of the Social Club who is highly respected and feared. With the fact that most students are in debt to the Morimoto Financial Group and her sister is the headmistress, she practically controls the school and will do whatever it takes to get what she wants. When Takuro arrives at St. Arcadia, she goes to great lengths to make him a member of the Social Club and to make him her personal sex slave.

The story revolves around Takuro Hayami who transferred to the mostly female Saint Arcadia School. Seemingly all of the girls want to have sex with him because the school only recently started admitting male students. Takuro seems like a normal student, but what the girls later realize when they try to take advantage of him is that he has a secret. Takuro has an "Ultimate Sex Power" that becomes the focus of St. Arcadia's sexual power struggle.

Based on the game by Active
