Karen, originally from Okinawa and longing for the north, created an entertainment district called SUSUKINO at the school she attends without permission, based on her own image, arbitrary opinion and prejudice! She created streets from Minami 3-jo to Minami 7-jo in the fictional city of SUSUKINO, and opened adult entertainment shops on each street (classrooms and audiovisual rooms)! A school paradise full of adult entertainment, including image clubs, men's esthetics salons, pink salons, SM clubs and boob pubs! She violates the discipline with her sweet seduction, saying, "Your willingness to study or not depends on this shop!"
