sorry for no repy! Let me try typing it now
Jade Summit Academy was "Hope's Peak Academy" in the original. The premise is the same; gifted individuals are scouted to go to this elite, government-funded school. The 77th class and the 78th class are significant to the story (as you guys probably know already)
The Reserve course was actually a way for the school to earn more money. The money was needed to found the Kamukura project, named after the founder of the school: Izuru Kamukura. Thus, the project was called "Project Hopebringer" in the rp, since the headmaster's name in rp was "Hopebringer". A certain Reserve student, Hajime Hinata (Agaricus), was asked if he wanted to be subject for the project. He was at risk of getting his brain irreparably damaged during the operation, but a success would give him the ability to excel at all talents known to mankind.
Howling, Imperial, and Wildebeast are the characters Yukizome, Munakata, and Juzo, Hope's Peak graduates that played a vital role in the Biggest, Most Awful, Most Tragic Event in Human History. (I changed it to 'Pyrrhian History' since the rp took place in the WoF universe). The Tragedy was set into motion by a single, high school girl known as Junko Enoshima (Rafflesia). Yukizome was the homeroom teacher for the 77th class, Juzo was head of security, and Munakata was the former "Ultimate President" who was in charge of the construction of an overseas branch of Hope's Peak. Yukizome was sent to investigate "the darkness" of Hope's Peak; the three best friends had caught wind that there was something shady going on at Hope's Peak (a.k.a. the Kamukura project) and wanted to unearth it.
Junko Enoshima was admitted into the 78th class as the Ultimate Fashionista/Ultimate Analytic, and she had a twin sister named Mukuro Ikusaba who was admitted into Hope's Peak as the Ultimate Soldier.
ok so skip ahead
Basically, the 77th class were supposed to have been brainwashed/broken by Junko, and they became the Ultimate Despairs. In order to do this, Junko killed their class president and forced them all to watch as she died a slow, painful death.
Junko also orcestrated riot in the Reserve Course. By revealing the identity of Izuru and broadcasting the reason to the Reserve Course's creation, all of the Reserve Course students revolted against the faculty. Afterwards, Junko caused them all to commit mass suicide
The 78th class hid in Hope's Peak, which had been converted into a bunker. However, that didn't help much; Junko was Mukuro were in the 78th class, so there was no escaping.
those are the main events? I watered it down a lot
