On a rainy night, a man lies curled up in the alleyway, covered in mud and seemingly lifeless. Dressed in a straitjacket, it's clear he has escaped from somewhere. A tall, beautiful woman passing by lights up with the gleam of someone who has just found a lost toy. She orders her attendant to pick him up and carries him into a suspicious room. This is a secret training chamber stained with the blood of countless men, and the woman is its mistress. The clinking sound of chains rises from her feet as she grips a whip known as the Nine-Tailed Cat. Stripping off his straitjacket, she mercilessly lashes the man's back, causing fragmented memories of his excessive lust to surface one by one. The woman has no interest in his past memories—she seeks only to record new memories, new rules for his pleasure under her control. Will the man be allowed to become her plaything once again?
