One of Sato's most repellent and excessive pinku-eiga films, this offering from the famed Nikkatsu film studios deals with a perverted psychopath who lives in a box and performs gruesome acts upon young women before bloodily murdering them. Sayaka Kimura stars with Takeshi Ito (Akai Joji), Rio Hashikawa, and Kiyomi Ito. The focus here is on sadism and gore rather than erotica, a fairly common occurrence in Japanese softcore during the latter part of the decade.
