How Long Is “Oni no kaen”?

When the beautiful Kumiko joins the editorial desk at a small local newspaper, the most deeply kept secrets of the rich and powerful leader of a religious cult suddenly begin finding their way into print in blistering exposes.

Ensnared in the escalating war of wits and chains between the sadistic cult master and Kumiko, his former sex slave, Shizuyo finds herself strung in the rope bonds of a ruthless game that mixes sensuality with humiliation. Could it be that Shizuyo's only hope of release may come in the form of her own husband's mistress? Or is that exactly what the Devil has been planning on all along?.
