Hinode Ikeno, a fashion designer gaining attention in Europe, is scouted by a prominent Japanese lingerie manufacturer and returns to Japan. However, the company that welcomes her has a secret plan in place to fully exploit her talent. Her superior, Hamada, and her colleague, Eriko, imprison her and subject her to physical and psychological training, forcing her to work as a ghost designer. Moreover, she is made to provide sexual services to the company's clients—something she never could have imagined—awaiting her as part of her new, twisted job duties.
