Quite upset by the actions of the violent serial murderer are both the department's coroner, Kyoko, and Natsumi, the second victim's pimp. Natsumi demands retribution; Kyoko just wants to get away from this nightmare. Later that night, at home, Kyoko sleeps, unaware that she is being stalked by the murderer. The killer breaks into her home using a glass cutter, and proceeds to bind her and rip off her clothing before attempting to rape her. Luckily, Natsumi, having wanted to talk with Kyoko privately, shows up at just this moment, scaring the intruder away. When Kyoko receives a package in the mail a few days later that is full of pictures of her being assaulted, she decides that she must take the law into her own hands. She reasons that Natsumi, though unaware, must have seen the killer as he fled from Kyoko's apartment. Enlisting her help to identify the perpetrator, Kyoko dresses sexily and makes herself bait (a "beautiful target," if you will) for the psychopath.
