Who is who (in my opinion)
Sonia = Celeste
Souda or terru terru = Hifumi
Nekomaru = Sakura
Akane = Aoi (?)
Nagito = Makoto
Peko = Toko
(Forgot his name,the baby gangster dude) = beyakua (I can't spell their names right)
I don't know maybe the first game survivors just managed to go to an alternate dimension or something?
Also Chiaki=Chihiro
Also Also wouldn't Byakuya just exist twice?
1: good theory
2: forgot them on there lol
3: maybe but peko and baby ganster dude (I really don't know how to spell his name) are a LOT like
Toko and byakuya so that's my opinion
DANGANRONPA THEORY:
WHAT IF THE CHARACTERS IN GOODBYE DESPAIR ARE THE CHARACTERS FROM TRIGGER HAPPY HAVOC,EITHER REINCARNATIONS OR THEM IN A DIFFERENT UNIVERSE
