Ibuki had been fighting against the evil organization Black Sabbas, but when her younger brother was taken hostage and brainwashed, she was captured by a trap he set. To control her powers, her body needed to be completely purified. This required thorough intestinal cleansing, forcing her to defecate while her anus was stimulated with a vibrator and special electrodes inserted and electrified. Enduring intense pain, she undergoes enemas with a special purification liquid called Black Poison to achieve total purification. Repeating cycles of defecation and enemas, Ibuki grows increasingly exhausted, eventually becoming completely broken down.
