Yuasa, indebted to the yakuza, was forced to work at demolition and waste disposal sites. One day, his body broke down, making it impossible for him to work. Cornered, Yuasa was offered a cruel proposal by the yakuza's Takamoto: "Why not send your wife to work at the site?" Unable to refuse, Yuasa had no choice but to accept. Thus, Yuasa's wife, Mai, was added to the job site duties, working as a sexual release for the workers.
