被俘女学生被训练成性奴隶的“学校”被摧毁已经一年了。但幸存者有川计划利用校长的女儿、前 66 号千秋来重建学校。他的第一个目标是绑架一位优秀的女老师，对她进行洗脑，让她成为学校的明星培训师。当有川绑架了他的目标高中老师泽村光子时，千秋彻底羞辱了她，将她关在角落里。当光子最终失去自我时，她的洗脑就成功完成了——或者看起来是这样。

It’s been a year since the “school” where captured schoolgirls were trained as sex slaves was destroyed. But a survivor, Arikawa, has planned to rebuild the school by using Chiaki, the former Number 66, who’s a daughter of the principal. His first objective is to kidnap a good female teacher to brainwash her into becoming the school’s star trainer. When Arikawa kidnaps his targeted high school teacher, Mitsuko Sawamura, Chiaki thoroughly humiliates her into a corner in confinement. When Mitsuko finally loses herself, her brainwashing is successfully completed – or so it seems.
