Under the guise of a college preparatory academy, high-IQ, academically gifted schoolgirls—pure and inexperienced with men—are handpicked and forcibly subjected to ●. These girls possess exceptional intelligence and physical beauty, and undergo a special evaluation to assess their qualities. Those selected are then put up for auction and sold to the highest bidders. The system's purpose is to breed superior offspring, aiming to increase future value through the children produced in this process.
