Cold Fish (18)

Tropical fish store owner Shamoto despairs about his teenage daughter Mitsuko, who is caught shoplifting in a local supermarket. Thankfully, one of the customers, Murata, manages to dissuade the supermarket from pressing charges by offering the girl some community service working at his own much larger fish store. Little does the father realise that Murata is a serial killer, who has slain countless victims with the help of his demonic bride, Aiko.
