By the way, Zeph, Audrey and Isaac are a ways behind everyone else, so he probably wouldn't be walking by them. It's not a big deal, but I thought I'd just mention it anyway. ^^'
Nari, the towns/cities of the Katsu region that have been mentioned so far (to the best of my knowledge, that is) are Chipper City, Frosty Gorge, Crystal City, Oran Valley, the Wellspring Foothills, and Shadow Valley. I would say Chipper City or the Wellspring Foothills are your best bets there, since they seem to be in the near vicinity and don't have any traumatic Uprising pasts. xD Mira would know better than I would, though. And I'm pretty sure we're just on a path through the woods north of Chipper City.
