Ayane Suzukawa lost her mother at an early age and lives alone with her father. One day, unknown men arrive at her home—loan collectors from a street loan company, demanding repayment of her father's debt. They corner Ayane, telling her, "If you satisfy us, we might reconsider your father's debt." With no choice, she reluctantly agrees. Surrounded by the men, she is raped and gang-raped. Thinking this would only cover the interest, she is horrified when even more men arrive to assault her. This series of events leaves a devastating impact on Ayane's life.
