A 'special classroom' created for the purpose of isolating students who cause problems into one class. The person who became the homeroom teacher was Kaori, who had just been assigned. However, this special classroom is dominated by Negishi, the most problematic child in the school. ``I'll get everything I want... including my teacher.'' Kaori, targeted as Negishi's new toy, succumbs to her violent power and is raped.
