Sacrifice (サクリファイス Sakurifaisu) is the 21th chapter of the Prison School manga, serialised in Weekly Young Magazine on July 16th, 2011 and published in tankobon format in Volume 3 on January 6th, 2012.


In the school courtyard on Thursday, Gakuto slides below Mari to remove her school skirt, to the utter shock of the other boys and Meiko. Mari's crows immediately flock to attack him & defend her, and Meiko whips him severely for his insolence. While an injured Gakuto lies prone on the floor, Mari returns to the USC office. The boys immediately gather around a battered Gakuto and send him to the infirmary, but not before Gakuto hints to Kiyoshi at achieving the key objective of his new breakout plan. After visiting the infirmary, Gakuto goes to 'apologise' to Meiko and opts to have his prized long locks of hair shaved as a punishment, conspiring to steal the removed hair. That night after the prisoners' labour shift, he returns to the mess hall of the Prison Block as a skinhead to the shock of the male prisoners and proceeds to secretly reveal his cut locks in his bag to Kiyoshi. Though he responded with disgust, Gakuto reveals to Kiyoshi that having long hair would be vital to the success of the breakout & that his hair will function as a wig on the day of the breakout to make him look more feminine when he crossdresses. Kiyoshi promises Gakuto to succeed in stealing a uniform and breaking out with only two days left before the breakout.
