Kaidan Oiwa no borei

About 1786 the doings of a demented lord results in many masterless samurai, including Iyemon who is used to luxury & cannot adjust to the hand-to-mouth conditions & piecework of umbrella making. Having hired ruffians to make him look like a superior swordsman, he arranges for himself the opportunity of a profitable marriage. He hires the half-blind masseur Takuetsu to seduce or rape his wife, so that she can be divorced or killed for adultery. But the masseur informs Oiwa of her husband's plot. (Bloody Disgusting)
