Miho, the daughter of a wealthy family, had just moved to the city to attend university and started living on her own. Shortly after beginning her college life, she was suddenly visited by Kitashiro, her father's servant, who claimed her father had been urgently hospitalized. Rushing to get into the car, Miho was drugged and woke up imprisoned in an isolated room. There, she was brutally raped by Kitashiro and his accomplices, enduring relentless sexual abuse for an entire month. When she was finally released, Miho's womb carried a child—its father impossible to identify.
