in kuoh academy there was much about it. It used to be a private all girls academy, and it allowed for boys to be part of the academy as well. On the campus of kuoh academy there were sometimes perverts, attractive girls, and another secret the students don't know.

at somewhere at the campus, there was Isabella hyoudou(name for issei but female) a third year student of kuoh academy she was like every girl attractive, curvaceous, and big "bust" though she was somewhere in number four of the academy most attractive students. But the one thing no one never knows about isabella is that she may be an attractive girl, but she's a huge pervert because she wants to be either her own harem queen or be part of a harem with a attractive man like every girl and she's not good at hiding that she's a pervert but soon that will change for her

at campus Isabella is walling with her friends discussing about something
