Following the betrayal of their ally, Rinko finds herself at the mercy of the underworld leader, Ryal. Through a combination of mental manipulation, brutal sexual assault, and two weeks of agonizing confinement within a demonic "flesh vessel," Rinko's will is systematically destroyed. Ultimately, the once-proud Taimanin is broken, fully submitting to Ryal as a slave prostitute alongside the already fallen Yukikaze.
