Vengeance Is Mine (復讐するは我にあり Fukushū suru wa Ware ni Ari) is the 86th chapter of the Prison School manga, serialised in Weekly Young Magazine on March 4th, 2013 and published in tankobon format in Volume 9 on July 5th, 2013.
Sometime later, some of the girls are talking about the guy who was found naked and bound in rope in front of Mitsuko, and Andre overhears them, at first jealous of him, but then thinks that it might have been Joe and gets worried. Andre goes to his room and finds that his spare rope is missing while Joe is at the school pool looking at all the girls. Andre confronts Kiyoshi and Shingo in the classroom. Andre tries to get them to go and find Joe with him, but they refuse, saying that they're meeting up with Chiyo and Anzu, respectively, causing Andre to get angry with them. Kiyoshi and Shingo are still confused, and Andre says he knows why Joe wanted to go back to the Prison Block, and leaves them alone.
Meanwhile, Gakuto and Mitsuko are walking through the hallway talking about the book they found at the library. After awhile they come across the dog from the other day. Gakuto thinks he just wanted to see Mitsuko again because she's so kind, but then the dog uses its snout to lift up her skirt and stick its snout in, embarrassing her. While all of this is going on, Andre is still frantically searching for Joe, and eventually finds him, about to burst into the women's locker room so he can get sent back to prison again. In pursuit of Joe to intercept him, Andre, runs past Gakuto and Mitsuko and runs into her, causing her to fall down onto the floor and spill large vats of liquid wax over the school corridor.
