Aizawa decided to take all of class 1–A to a prison for a day, mostly just to learn about the prisoners, and get a rough idea of why they are the way they are. As class 1–A are walking around, word was going around that a new inmate was in, for taking advantage of, and killing a little girl, which happened to be one of the other inmate’s daughter. The inmate who was the father of the girl, apparently slowly stabbed the predator over fifty times with a red hot blade because of it.
