Effusion Plan.Since the urination incident, Hana left from being an overseer, leaving Meiko to check up on the boys. As the escape hole grows bigger, Gakuto asks that Kiyoshi does a test run of the escape route. On his way back, he witnesses the Chairman burying nude pictures. Shingo starts feeling left out by Kiyoshi and Gakuto, seeing them talk frequently. In preparation for a track meet, Kiyoshi, Gakuto, and Shingo are placed on belongings' watch duty, but Shingo transfers with Andre and Joe to miscellaneous jobs, after witnessing Kiyoshi and Gakuto taking a shower together, thus putting Shingo out of the way. Kiyoshi notices a drainage pipe that leads from the bathroom to near the escape hole. A test run results in Meiko stepping on Kiyoshi's butt and causing it to bleed, which Shingo mistakenly claims is a case of hemorrhoids. Later, during I.T. class, Gakuto plans on using his audio player to play fake defecation noises when Kiyoshi is "using the bathroom". However, when no audio clips pop up, he decides to make his own by defecating himself. Despite their efforts, they find out the hole had been patched up, not realizing the Chairman did it while re-burying his photos. When Kiyoshi devises another plan to sneak out by cross-dressing, Gakuto aids him once more, as he intentionally strips down Mari's skirt.
