Silverbell narrowly escapes being brainwashed by Black Satan and awakens to save her life. Determined to rescue her lover Masayuki, she infiltrates the enemy organization. Her mission is anything but easy. Repeatedly placed in life-threatening danger by the enemy, each time she survives a crisis, new humiliation and suffering await. Her neck is constricted by wires, and she loses consciousness just as she involuntarily urinates. Her lover exposes her to electromagnetic waves, stimulating her urethra and forcing her to pee in an embarrassing pose. Electromagnetic rays are also aimed at her anus, provoking an unbearable urge to defecate, which she ultimately cannot resist. Burdened with the Electric Thunder Weight, she struggles under its crushing pressure and overwhelming bowel urge until she finally defecates. She is given an enema with an Irrigator, then subjected to spanking and chokeholds with a body blow lock, but unable to endure the torment, she defecates again. Her mask is ripped off, exposing her shameful state to her lover. Silverbell's existence remains constantly caught in a whirlwind of danger and humiliation.
