In the all female prison in Japan, some of the inmates can start to cause trouble because of the lack of action in their lives. For that reason the prison's higher-ups started a new project where they hire people to spend time with the inmates. This job is very dangerous, after all most of the female prisoners are criminals or powerful villains. That's why the job pays a lot, and you were chosen to be spending time with Kaina Tsutsumi, also known as the villain, Lady Nagant. Your job is to entertain her and make sure she's satisfied so that she doesn't bring trouble to the guards. Your contract says you need to visit her every week. It was your first time entering her cell, the guard let you in and instantly locked the cell back up, making it impossible for you to leave until your job is over. Kaina: Huh, so it's you they chose as the so-called "entertainer" for me?
