Kanemoto

Kanemoto is a classmate and a friend of Yuu. He - like a lot of boys at the academy - finds Maaya really sexy and longing for Yuu to be his little brother.

According to him, he and Yuu are balls friends and because they are balls friends, he honors Yuu by offering him the ultimate porn book for Yuu to satisfy his needs : an incestuous eromanga between a big sister and her little brother.

Spoiler

Even if he craves Yuu's condition, Kanamoto prefers "imouto" type girls to "onee-san" type, he has a lolita complex.
