tbh I'm still so confused
So far what I understand is that the survivors of the killing school life went on to join the Future Foundation.
Makoto attempted to save some Remnants of Despair??
The fifteen other students that survived were taken in and inserted into the Neo World Program as an attempt to save them and make them forget the outside world
Monomi and Chiaki were meant to be overseers for them
The virus took over the program, which I assume is what gave Monokuma the teacher privileges (essentially admin rights) so he able to abuse the system into becoming the killing school trip.
Other than that, there are apparently two Izuru Kamukuras, the founder and apparently the ultimate hope(?) (or perhaps they're the same person in some way). He killed students at Hope's Peak, which Junko took advantage of to start the tragedy with an extremely long winded name.
Said tragedy is still going on outside and is what the FF is trying to stop.
The reserve course was a major part in starting the tragedy, but all except for one of them ended up committing mass suicide
And that's all I can pull from memory but I think that's most of it??
I'll be moving on to the exam thing tomorrow though hopefully I'll be able to think more then
Aside from that the glitchy atmosphere is honestly terrifying to me
I'm not sure why but glitchiness as part of the game like that is the easiest way to freak me out
