Saya Yukimi wakes up to find herself in a dark basement. Standing before her is a man holding a gun, looking down at her with a smug grin. The suspect she had pursued with all the pride of a detective has overpowered her, taking her firearm. His voice cuts through the silence: "Do exactly as I say if you don't want to die." With a humiliated expression, Saya begins to masturbate. She tries to convince herself, "There's no way I'll feel anything," but the writhing vibrator inside her vagina strips away her resistance. One ordeal after another closes in on Saya, driving deeper wounds into her mind.
