I dunno that I know as much as others to try explain. But. You know about the Retrospec app, right? Those of us that have it, we get memories and belonging and abilities from this other life, thanks to Retrospec saving our souls. Apparently. Something like that?

[Yuu isn't the most philosophical or whatever to really go into questioning or analyzing this nonsense like others might. Nor has he had the app as long as some. It's been a few months though, so he is more or less used to this stuff in what to expect?]
