The world, you see, is full of 'If's.
Without the If of Eve being joined with Adam, society as we know it would never have existed. This world inwhich you live is only one of countless Ifs, constantly being propelled forward like a pool of mud by these possibilities. Miso soup no naka de, if you will.
What follows is an Iffy world where Ifs If Ifs. An uncertain Klein bottle where the surface and the inside are one and the same. ...Oh, don't break it, now. None of you bastards could afford to pay for it.
Ahem. Anyway, this is a world of Ifs. You could speculate and guess and make conjectures all you like, but only the future is a flexible pool of mud. The past is more solid than a -40 degree banana. The past can't be changed, and looking into 'A World That Could Have Been' won't save anyone in the real world. After all, an If is only an If. And even if there was a sickening parallel world where that particular If became real, humans can't cross those lines so easily. In this case, all Ifs are Divergence Ifs.
...You still wanna see it? You've got some sick hobbies, you know that?! Don't you think that's like desecrating Naegi-kun and the others' efforts? They're moving forward past that tragedy now, you know! ...
I'd still heap desecration on them, though. Upupupupu...
If you really wanna see this If, then it would be best if you looked at the surface of the Klein bottle first.
Maybe start by playing this game called "Dangan Ronpa" through to the end. And try to play multiple times so you get to hang out with Junko Enoshima about three times. And if you finish collecting all the items and movie clips, you're just about perfect to go.
But I guess the fact that you're already here means you obviously did all that. I'd still buy it, though. I'd still buy two copies of Dangan Ronpa!
