I believe all the parallel worlds have the side effect of having thicker mana in the atmosphere which is what allows humans to use magic and the world Nero comes from doesn't have that so I'm pretty sure they're from the original world.

Also parallel worlds didn't even exist before that event happened so it shouldn't be possible for them to escape to a different world before shit goes down but eh. Just wait for the explanation I guess.
