After spending half a year teaching the reserve class, Chisa asks Juzo for a trustee's ID in order to investigate something known as the Kamakura Project. Managing to return to her position as homeroom teacher of the 77th class, she is relieved to find that Chiaki has managed to keep everyone together and is given a warm welcome. Meanwhile, it is revealed that Ryota has been spending all of his time at home working on an anime, having the Ultimate Imposter take his place in class. Elsewhere, Junko Enoshima meets up with her sister, Mukuro Ikusaba, as they prepare to enroll into Hope's Peak as part of the 78th class. When Ryota ends up collapsing with a fever, the Ultimate Imposter seeks out nurse Mikan Tsumiki to treat him, explaining how he took on Ryota's identity so that he could stay at home and animate. As the new school year begins and the 78th class begin their life at Hope's Peak, Hajime goes through with the Kamakura Project.
