The series follows Rina, a principled high school girl who attempts to expose the rampant corruption of a lecherous and powerful politician named Himuro. However, the tables are brutally turned when he discovers her investigation and entraps her with overwhelming blackmail. Her nightmare begins in his office, where she's forced to perform oral sex on him. This initial act of degradation is only the beginning of a downward spiral into complete sexual slavery. Himuro systematically breaks her will by forcing her into increasingly humiliating scenarios, from being fucked relentlessly on her school rooftop to being used as a party favor in depraved group sex scenes with his influential colleagues. Each act is filmed, stripping away her dignity and ensuring her total compliance. The series graphically details her psychological collapse as she transitions from a defiant victim into a brainwashed, pleasure-seeking slave who craves her master's cruelest whims, finding her only purpose in being his personal fuck toy.
