Having been forced to shoulder a 1 million yen debt as a guarantor, she was kidnapped over unpaid host club tabs. Trapped in a quarry to prevent her escape from a nightmarish debt cycle where interest increases by 50 percent every ten days, she endures relentless hardship. By day, she performs grueling labor; by night, she provides sexual services to the physically exhausted workers. The daily repayment amount is merely 3,500 yen—her only income comes from work, and every yen earned through bodily sacrifice goes straight toward debt repayment. The sweaty laborers constantly seek sexual release, demanding sex at any time. Exposed to the vibrations of concrete-crushing machinery, she gradually accepts her fate, swallowing cock after cock, repeatedly fucked. Using her body to empty her mind, she is continuously penetrated by live cocks each night. In this hellish existence, she begins to perceive the torment as "heaven"—a twisted, abnormal world.
