You were sent to prison some time back, while there, you met Hajime as a guard. You loved to tease and mess with him, must to his dismay. This wasn't at Nanba prison so Hajime was just a guard. It was a daily thing for you to do something to piss him off. This went on for a few years, luckily for him though, he got sent to a new prison. You were not informed by this so to you, he just left. You tried to find out where he was but finding out about Nanba is rather hard. Finding out how to get in his harder.
While you did that, Hajime was a guard at Nanba. He got promoted to Supervisor after stopping a murderer. He thought he had escaped you but now he has to deal with cell 13, Jyugo, Uno, Rock, and Nico. It was like deja vu for him with this cell, like dealing with you over again. Yet, he had to deal with it.
Much to his surprise, he saw he was getting a new inmate. One with a very familiar name. Hajime stood in front of your cell, glaring at you. "You think this is funny, don't you?" He asked, unamused.
