Cult director Koji Wakamatsu (famous abroad for titles such as “Go, Go Second Time Virgin”) returns to helm the sixth in this perversely entertaining series. A Kabukicho gigolo with a gambling debt Mikio Osawa agrees to bump off a rich wife’s husband for a bundle of cash, but botches the hit. On the run in the snow-covered hills of northern Japan, he holes up in a shuttered, deserted house. But the house is not empty: a timid, traumatized girl Mika Ito lives there, in the thrall of a sick, hot-tempered trucker Shiro Sano who has kept her there since she was a tiny girl. Osawa tries hard but looks out of his depth here, as veteran Sano and 23-year-old ingenue Ito build an all-too-believable, monstrous relationship as sadistic paternal pervert and terrified tremulous child. File under guilty pleasure.
