Of any filmmaker pushing the boundaries of Nikkatsu's successful "violent pink" line of softcore <i>pinku eiga</i> films in the mid-'70s, no one did it with more style and less conscience than Yasuharu Hasebe. This film comes off the outstanding Okasu! with another dazzling nightmare of erotic violence. Tamaki Katsura (nominated as Best Actress by the Japanese Academy for her role here) and Yutaka Hayashi star as a young couple whose increasingly kinky sex games lead them to slice and dice a number of young women with a cake-knife, starting a citywide panic. Hasebe strikes the perfect balance between blood and sex, which are intertwined as they rarely are in mainstream European films and almost never in American ones. Unfortunately, his next swing at the genre was the appalling Rape! 25-ji Bokan (1977), a film so unbelievably vicious and perverse that it all but halted Nikkatsu's production of violent pink for nearly two years.
