[Unfortunately for Kaito, Armin fully assumes that everyone here has figured out they're from different worlds by now, so he'll do nothing to clarify - honestly, he'd find it pretty foolish that Kaito hadn't figured it out yet. He supposes that he, himself, doesn't look all that out of place, though he feels it. As for "the spirit" that Kaito mentions, well...

[It's certainly something that Armin used to have. There wouldn't be much point in it anymore - after all, his world is gone. He ensured that, in his own way...

[To see all of the wonders of the world he never knew - he feels that that's a dream which died a long time ago.]

Well, I appreciate that. [His laugh is light, but perfectly genuine-sounding.]

All that being said - and as much as I'd like to learn more - we're in a bit of a predicament, as it stands.

[An overturned train to nowhere with a mysterious forest being the only exit. Kaito was about to wonder off into it.]

I think it would benefit us to come up with some sort of plan before we attempt moving through that forest. If these maps we've been given are to be believed, it's full of enemies. [What are, ostensibly, enemies, anyway.]

If you don't mind, I must ask - what ability do you have to defend yourself under these circumstances?
