 For years, Nikkatsu had been trying to recruit the "Queen of Pink," Naomi Tani, into their "Roman Porno" series, but because Nikkatsu had been reluctant to enter the S&M genre, which was Tani's specialty, she had refused.When Nikkatsu finally consented to Tani's request to star her in a film based on Oniroku Dan's S&M novel "Flower and Snake", the film—"Flower and Snake" (1974), directed by Masaru Konuma—became one of the studio's first successes of the year.The studio followed this first successful venture into the S&M genre with "Wife to be Sacrificed", another starring role for Tani, again directed by Konuma.
