Having lost her mother at a young age, Yuri was raised under the sexual domination of her father, Ginniji, who has an SM fetish. For years, he subjected her to bondage and tight restraints, controlling her life completely. After marrying and moving out to live independently, Yuri thought she had escaped—but Ginniji secretly broke into her new home and continued his acts of violation. One day, her husband returned to find her engaged in a bondage sex session with Ginniji. Discovering his beloved wife's secret, he flew into a rage, verbally abused her, choked her violently, and forcefully ■ her. In the aftermath, dazed and broken, Yuri faced her husband's fury, leading to divorce. She was then taken back by Ginniji, who subjected her to even harsher training and control.
