The Mask (マスク Masuku) is the 202nd chapter of the Prison School manga, serialised in Weekly Young Magazine on January 9th, 2016 and published in tankobon format in Volume 21 on June 6th, 2016.


In the sports ground on the main stage of the Sports Festival, the members of the cavalry team assemble for the All-Student-Council Cavalry Battle. When the carbonated drink masked delivery system on Meiko's back is revealed by its proud inventor Gakuto, a shocked Kate objects to the usage of the contraption. However, Gakuto claims that it is only for the hydration of Meiko. The cavalry battle is revealed to be elective and open to schoolgirls from the student body - who are given the choice of white or red headbands to join in as their own cavalry teams. However, all the schoolgirls opt to join the Aboveground Student Council's side which Mari attributes to their dwindling popularity - leaving their side outnumbered ten-to-one. In a ephemeral moment, Mari voices her regret for imprisoning and mistreating the boys - which the boys respond to by asking her to fund the upcoming barbeque party for the USC's prison release date. The three USC cavalry teams don their handmade headbands and assemble against the massive crowd of schoolgirls in the ASC cavalry army.
