Just when her territory reform was finally getting on track and her job as a Viscountess was getting more interesting, Mitsuha is told she needs to come to the Royal Capital for the social season?! She quickly teleports to the city to fulfill her duty as a noblewoman and to promote specialty products from her territory, but then she gets "captured" by that little devil of a princess, Sabine. Using Mitsuha's secrets against her, she pesters Mitsuha for the right to tend (or rather, the right to use the equipment at) "Mitsuha's General Store." But there's no way Mitsuha can let all of the conveniences of civilization in the store be at Sabine's disposal... What will Mitsuha do?!
