It's all solid theorizing but...[He shrugs. He can understand why everyone from Remnant would disappear, but why Yu?] I'll have to ask when they come back. See what happens. When two other friends of mine, Sorey and Mikleo, disappeared, they both came back with more memories than they'd left with. They're from the same world, they've known each other for forever.

I guess you could say everybody comes back differently either by remembering more things from home, or not remembering this place at all. People say I've been here before, too, and I don't remember any of it.
