Mad Wax (マッドワックス Maddo Wakkusu) is the 87th chapter of the Prison School manga, serialised in Weekly Young Magazine on March 11th, 2013 and published in tankobon format in Volume 9 on July 5th, 2013.


In the school corridor, Andre decides to slide on the large wax spill floor to his advantage to get to Joe faster despite his doubt of reaching Joe in time. When he contemplates why Mitsuko is travelling so quickly, he realizes that her speed is due to the exposed skin of her body and notices the visual resemblance her upskirt has with Meiko's underwear. Inspired by his masochistic urges, Andre decides to remove all of his clothes to increase his speed. Though it miraculously works and he is nearly able to catch up to Joe in time, a girl from the cooking club stops Joe and offers him a cupcake. When she introduces himself as Satou, he hesitates over whether he is speaking to her. Having abandoned his plan, Joe steps aside from the door and accepts the cupcake only for a bondage-rope wearing Andre to reach their corridor sliding on the floor to the fright of the two onlookers. Though he realized that Joe is no longer planning to carry out the voyeurism, Andre is unable to stop himself and barrels naked into the girl's changing room himself to the disgust of the female occupants. This makes Gakuto and Mitsuko assume that he was the pervert with the rope from before. An oblivious Gakuto explains this to the newly-arrived Kiyoshi and Shingo, while a satisfied Andre recieves a brutal beating by all the women in the locker room.



  • The chapter was adapted into a titular OVA following the completion of the first season of the Prison School anime.
  • The chapter title is a cultural reference to American dystopian thriller franchise Mad Max.
