Kind of like how there are a lot of people from parallel versions of this world, too, that are all a little different. Like, mine doesn't have vampires and Thorne's does, but they both have California, and Raidou's has demons and mine doesn't.

Like, is Earth somehow really important in the scheme of things, to have this many versions of it? Or is it really just random that so many of us come from Earth, and we visit Earth so often?
