Azusa is a second-generation female detective who took over her father's office two years ago. She believes that this job is her calling, as it allows her to utilize the power and stamina of her voluptuous body. However, when she infiltrates the office on a request, she is captured by the yakuza who were waiting for her, revealing her poor judgment of the situation. The evil beasts who make a killing from human trafficking decide to get a taste of the perks of the job before selling the baby-faced, glamorous, beautiful detective overseas, and they subject her to bondage and sexual training to their heart's content, turning her into a big-breasted, big-assed female sex slave.
