Class 77th

Class 77th is a batch from Hope's Peak Academy. There are total of twenty known students divided into two classes, 77-A and 77-B. The official homeroom teacher of Class 77-B Koichi Kizakura, before being replaced by Chisa Yukizome.

Junko Enoshima who was targeting the Class 77-B as her pawn to start The Tragedy, executed the class representative, Chiaki Nanami and converted the rest of the class into despair with them watching the brainwashing recording of Chiaki's execution.

After Chisa and her students became a part of the Ultimate Despair, also known as the Remnants of Despair, contributed to spread despair throughout the world until they were captured by the Future Foundation. Makoto Naegi from the 14th Division secretly sent the Remnants of Despair to Jabberwock Island and undergo the Neo World Program in order to delete the brainwashed effect. An A.I. was created to observe them, and the A.I. decided to take the form of Chiaki as Class 77-B desired to see their class rep again.

As they awaken thanks to Hajime Hinata/Izuru Kamukura's talents, Class 77-B went to the location of the Final Killing Game and prevent their classmates, Ryota Mitarai from brainwashing the world with his Hope Video. All of them decided to atone their sins as the former members of the Ultimate Despair and lived in Jabberwock Island in peace.
