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??

Having saved the kingdom from invasion, Mitsuha suddenly finds herself elevated to the rank of viscountess. Exploiting her world-jumping ability to the fullest, she’s now busy improving things in her new domain (with a little help from Earth’s advanced knowledge and technical skills). But with ballroom season on the way, it’s her obligation as a noble to return to the capital. Sure, the timing couldn’t be worse, but it might also present a perfect chance to showcase her new flagship product—popcorn?!

That’s not the only iron Mitsuha has in the fire, though: when she decides to hold a tournament to drum up sales for a new line of board games, things go a little too well! Between that and the arrival of unexpected visitors from a distant land, the newly-minted Viscountess Mitsuha von Yamano really has her hands full!
