[Oh - right. The look on Mahiru's face, hearing that, makes it a little obvious that she's forgot that herself.
But she was just as confused when she showed up, so... it's not like she can fault Peko for not understanding.]

I know - it's a little hard to explain. Tanaka said something about parallel universes... but it feels more like people show up here from different times in their lives, at different times.

Kuzuryuu and Tanaka have been here even longer than I have. And... apparently, I was here before this, turned into a completely different... monster - [Said with a gesture toward herself-] - and just don't remember.
Whoever brought us here doesn't seem to like doing things that make sense.

... There's a lot more to this, too. But I think I'd really rather save that for Kuzuryuu to explain - he understands it better than I do, and I really don't want to mess it up trying.

[And she's not sure how Peko would take the "you're not actually dead" talk coming from the girl she killed.]
