RBK-039 — New Slave Investigator 9: Maniac's Target

I want to do whatever I want with a woman. But it's boring if she's weak from the start. A tomboyish woman is caught in a villain's trap, trained while covered in humiliation, and finally becomes a pitiful sex slave who bows down to me and serves me. That's the situation I want, isn't it? ...The woman that Kirisaki, a trainer who received a request from a maniac, has his eye on is the completely invincible elite investigator, Hojo Sakura.
