It's time at last for the board game tournaments, and Mitsuha's the prize?! She was so busy dealing with invaders from across the sea that she completely forgot about the Reversi and Shogi tournaments. And they're expecting 30,000 competitors?! With the Lightning Archpriestess who saved the kingdom presiding over the competitions, of course, everyone wants a piece. Anticipating chaos, Mitsuha calls an emergency viscounty meeting for ideas! Will she be able to handle absurd prizes like "the privilege of caressing the Lightning Archpriestess and squishing her cheeks" for the sake of the people of her domain?!
