[Ah, right, apparently being taken to multiple worlds isn't exactly the norm for most people. Ochako makes a noise in her throat to affirm she heard the last part but she'll address it later, the former matter seems a bit more pressing right now.]

Mm, well...it was actually just the one world outside of my own. So...I was first in my world, Japan, then taken to another world because of something happening with time, where moments in time all across the multiverse were repeating again and again without end...so the world responsible for that took us in as refugees. That world was Nippon. Then I appeared here, in Trench, from Nippon.

So...two new worlds overall. Trench being the second after Nippon.
