The "Alleycat Rock" series came to an end when Kaji left Nikkatsu to join Toei studios and star in the "Female Prisoner: Scorpion" series and "Lady Snowblood" (1973). Hasebe also left Nikkatsu in late 1971, when the studio decided to compete with the "Pink film" genre, and produce almost nothing but softcore pornographic films which Nikkatsu labeled "Roman Porno". Hasebe later commented, "to be honest, I am not good at making sex films."
