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?!

There's no way a brand new, 18-year-old viscountess with no retainers will be able to manage her new territory all by herself. So first, she must secure human resources from among those she trusts in the other world! That said, one can't do much without proper funds, materials, or technology. But since Mitsuha even has the internet at her disposal, she'll move forward one step at a time with the help of her appointed vassals. Plus, it's time for the secret of Mitsuha's world-jumping to be revealed! But with all this work to do...when exactly will Mitsuha be able to earn gold for her retirement?!

Having gathered the necessary human resources to reform her territory, Mitsuha visits the Wolf Fang base for the first time in a while. It is there that she learns agents from around the globe are spying on her! Her hopes that this won't turn out to be a hassle are quashed when she is approached by mysterious men in black outside of the base. Is this merely an interesting turn of events? Or is Mitsuha actually in a whole world of trouble?!

Char to turn the table and free the people from the fates of death!

Mitsuha is your average teenage orphan-until one day she falls off a cliff, and finds herself in another world strangely akin to medieval Europe! Beset by wolves, she discovers she has the ability to travel freely between the two worlds, and decides to make a life for herself in both. Now all she needs to do is save up 80,000 gold coins for a comfortable retirement... Piece of cake, right?! No matter how out of control things get, Mitsuha keeps her cool, turning every hurdle into a business opportunity. From shopkeeper to war hero to viscountess, her meteoric rise seems unstoppable-but with each success comes new obligations and new costs. Does every step up just take her further from her goal??

Mitsuha Yamano falls off a cliff, at which point she finds herself transported to some sort of medieval European fantasy world! While there, during a battle with some wolves that almost costs her her life, she realizes that she has the ability to come and go between Earth and this new world. Mitsuha decides to use this ability as much as she can. Why? To save up for retirement, of course! She sets her sights on saving eighty thousand gold coins--and this is the story of her schemes to get there!

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!!

Mitsuha and her hired mercenaries, Wolf Fang, have just about wrapped up their battle against the invading Imperial Army and its monsters, wyverns, and dragons. And what awaits Mitsuha as a reward for her efforts but her very own viscounty! She's now a noble landowner in the other world at 18 years old?! So much for just trying to make gold for her retirement...

That is, until a neighboring kingdom launches a surprise invasion! At first, Mitsuha intends to stay out of the fray, but after being summoned to a war council meeting, a particular incident ignites a fire inside her. Will the Lightning Archpriestess be able to lead her adoptive kingdom to victory against their attackers?!

The Unexpected Team-Up Following the smashing success of Adelaide's debut banquet, what appears to be a classic fantasy adventuring party shows up at the “General Store”!

It's the perfect chance for some in-the-field market research!
