Oh dear! My mistake, Gokudera. [The apology in his voice and in his smile at least is genuine, holding one hand up as though in surrender.] Where I'm from, we usually state our surname first.

[So he can rule out Gokudera being from Inazuma. Without any real reaction to the nation's name at all, he likely isn't from his world at all. That honestly just makes him far more interesting!]

So tell me about your world, then! You seem particularly keen on returning to it sooner than later. There must be something important waiting for your attention, hm?
