21-year-old Yuri graduated from junior college and got a job at her local city hall in Saitama Prefecture. She had never dated anyone before, and her first sexual experience was a traumatic encounter at a hostess bar, where she was forcefully taken by two men introduced by a friend. This incident left deep psychological scars, yet she began frequenting hostess bars for free sex as a twisted hobby. Another passion of hers was stock market investing. One day, a thread titled "City Hall Employee Obsessed with Hostess Bars" appeared on 2channel, posting explicit photos of Yuri's orgies. As a result, she was forced to resign from her position at city hall. On top of that, she suffered massive losses from stock trading and was left drowning in debt. With no other options, Yuri had no choice but to apply for high-paying part-time work.
