Black Kiss(2004)

All she wants is a little kiss...

Black Kiss is a Japanese thriller following Asuka, an aspiring model who moves to Tokyo to chase her dreams. She settles into a cramped apartment with Kasumi, a stranger she's never met. When a grotesquely staged murder erupts across the street—the victim's body arranged like macabre art—the killings multiply around them. Each crime scene bears the same calling card: a black lip print left by the perpetrator, soon branded by police as "The Black Kiss." As the murders escalate, Asuka and Kasumi find themselves caught in the killer's orbit, unsure whether they're witnesses or targets. The film weaves psychological tension with visceral horror as the two women race to identify the murderer before they become the next victims.
