Underground cult director Kazuo Komizu, using the pseudonym Gaira, created quite a stir with his trio of erotic horror films which push the envelope of near-pornographic sex and violence about as far as it will go. This was the first of the trilogy, a story about a pretty psychologist (Megumi Ozawa) who is raped, murdered, and dismembered while trying to avenge the suicide of a patient who was raped by a Yakuza gangster. Buried along with the remains of a rival gangster, Ozawa somehow melds with his corpse and comes back from the grave as a hermaphrodite zombie bent on revenge. The blood flows heavily and often, and the murders are quite extreme, including an inventively perverse sequence in which the gangsters wife is forced to perform oral sex on the bisexual monsters male organ while the female one suffocates her. Gaira got even more perverse with Goumon Kifujin and the legendary Shojo No Harawata over the next two years. ~ Robert Firsching, All Movie Guide
