Plot
Enoshima Junko reveals that she had used Ikusaba Mukuro, her older twin sister, to take her place, before showing the others footage of the outside world. It is revealed to be in total chaos, which is confirmed by Genocider Syo, who retained her memories due to them being seperate from Touko Fukawa's. It is then revealed that the memories that were stolen from the students were actually of two whole years spent together in Hope's Peak Academy. A year ago, when a terrible incident hit the world, the school was converted into shelter to protect the students carrying hope on their shoulders. However, Enoshima killed the principal, erased the students' memories and began the killing game, even betraying her own sister in the process. Enoshima then holds a final vote between hope and despair; if everyone votes for hope, they must leave the academy, but should even one student vote in favor of despair, the students will remain in the academy and Naegi Makoto alone will be executed. However, Naegi manages to use his own hope to inspire the others to stand up against despair, earning him the new title of Super High School Level Hope. With the trial over, Junko revels herself in the ultimate despair and gives herself the ultimate execution, leaving behind an escape switch. With hope in their hearts, Naegi and the others use the switch to leave the academy and venture into the unknown world, unaware that Monokuma is still active.
