The board game tournament is finally over, and Mitsuha’s General Store is open for business...occasionally, anyway! Actually, Mitsuha’s going to be away from the capital for quite some time, now that she’s been attached to a diplomatic delegation?! She’s already got a lot on her plate, but she can’t very well ignore a command from the king himself…

And so Viscountess Mitsuha von Yamano, aka the Lightning Archpriestess, sets off with Sabine and Colette in tow... But with a fully-equipped RV—not to mention Mitsuha’s world-jumping power—it’s not exactly going to be an arduous journey. Delicate negotiations, handsome princes, and bandit raids await as the girls leave their kingdom and their comfort zone for the first time!!
