Professor Saki Azuma began as an ordinary woman until her psychological state twisted under the sway of her sadistic boyfriend, Mikami. Manipulated by Mikami, she secured him a teaching role at her all-girl college after his prior dismissal for assaulting a student. His escalating coercion drew her into complicity with his predatory targeting of female students. Compelled by her relationship with Mikami, she exploited her academic position to assist him in orchestrating abusive "private sessions." This collaboration originated in profoundly misguided loyalty and affection, revealing her psychological entanglement and eroded autonomy. The narrative portrays her as a tragic figure: her initial normalcy methodically dismantled by external manipulation, culminating in her participation in harming others.
