Asuka is an aspiring model who moves to Tokyo to pursue her career. She moves into a small apartment with a friend of a friend, Kasumi. A bizarre murder occurs in the hotel across the street. The body was mutilated and repositioned into a lurid work of art. After this, a string of murders start happening all around the two girls, as if some crazed serial killer was following them. At the scene of each crime, the perpetrator leaves a black lip print, and is subsequently dubbed "The Black Kiss."
