>>45801532I think I'd start in Galar, at the beginning of the wild area.
I'd pick Cynthia to tutor the group and save my ass from practically any and all threats, Klara to tease and have a siblingly rivalry with (also for the company of someone who's at least as shit as I am), and Flannery because she's a shitter fuckup who would make me look good by comparison.
So we'd basically spend our days getting babysat by mommy cynthia and squabbling among ourselves, poking the wrong Dynamax den and running from the unbridled fury of a pissed off G-max Snorlax. Then the two younger girls would get gym-leadering lessons from the Champion herself and I'd sit in to listen, tenderly raising a Dreepy or some other sufficiently-weak shitter. Endgame after we've all gone our separate ways is I live out my days in the wild area (being the undocumented otherworlder that I am), becoming a hermit to-go expert even the Rangers turn to when they need directions, and battling any strong trainers that happen to pass by.
