Masaru Takesue

After a coffin is delivered to a sleepy little Japanese town, one of the locals discovers that its occupant isn't dead yet. Unfortunately, the only witness to the vampire invasion gets bitten, along with several other people in town. Only one woman, Akiko, knows the truth, but even she doubts what she is seeing. Can the village be saved before it's too late? (imdb)

Utamaro paints, secretly watches couples have sex in order to bolster his understanding of the female form, aids a legendary thief alongside his counter-culture artist friends, engages in an affair with a beautiful pickpocket, sanctions the rape of his wife to inspire yet another painting, falls in love with a noblewoman, and then nearly loses everything when he and his fellow artists upset the shogunate by "creating disturbed minds," which they believe is the biggest threat to their rule.

Acclaimed Nikkatsu studio pinku eiga filmmaker Chusei Sone directed this action-packed softcore melodrama concerning a group of female ninjas who use sexual magic along with their considerable fighting skills to protect their province from takeover by a ruthless shogun and his band of fighters.
