Toyosu Airu

Is the class representative of the protagonist's class. A rich classmate.

Cannot forgive the protagonist, who does not strive towards becoming something befitting of being called a man.

Gives off a bit oppressive feeling but that is to hide her weaker inner self. In reality, she is actually a very kind-hearted girl.

Like a lady, she takes lessons in traditional Japanese dance, tea ceremony, flower arrangement, etc.

Though she has excellent grades, it is mostly the result of her effort.
