ichikawa riku, female school student, 20 consecutive departures

The girls' school was the target of a slut in their class. Male students demand money, are sexually treated, and continue to be sexually harmed by teachers. The physical education teacher is called to have no physical strength, and he is sluggishly asked by the English teacher to practice pronouncement and frustration. Soon the head of the teacher and even the principal get involved and continue to commit crimes with a whirlpool! there's only this school, kuz.
