[Miu shakes her head.] No, that shouldn't matter. I've tracked someone more or less all across Japan before, but... Let's say I'm tracking someone who gets on a train. While I know they got on the train, I probably won't be able to tell where they got off at--it's not like a voice is going to pop into my head saying 'they got off at Osaka station.' I'd have to try the trace again at each stop to see if they got off there, and then I could pick up the trail again.

...Honestly, I haven't tracked someone who's gone, say, overseas before, but the idea should work the same. If I touched down in the same place they've been, I should be able to pick them up again.

['Other worlds,' though... Miu hesitates a little, her brow furrowing as she thinks about it.] Well...I guess that depends on what you mean by worlds. Where I'm from there's the world of the living and the world of the dead--I can track someone who's crossed over to one or the other. If you mean like... Could I track someone from here to your world? I'm not sure. They would've had to be in this world first and then I could track to the last place they were before going back or something.
