Thanks to her ability to freely travel between worlds, Mitsuha’s business is booming. One day, she witnesses a group of men trying to abduct one of her female customers. Mitsuha stops them with her stun gun, taking the opportunity to deliver a cool line she has always wanted to say... “I am the Lightning Archpriestess! Those in my way deserve no mercy!” After dealing with the would-be kidnappers, she discovers that the girl she saved is actually a princess! Just as Mitsuha tries to flee the scene, she is invited to the royal palace. Just how will our general store manager fare when called to an audience with the king?

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!

The manga of the popular light novel series about being plunged into another world, and taking it for all it's worth! After growing up an orphan, Mitsuha has a healthy respect for money and a desire to live well--at least, until she dies after being pushed off a cliff. Waking up in a strange fantasy world, Mitsuha narrowly survives an encounter with a pack of wolves, then realizes she has the power to move between this world and the real one. A lesser person might embark on heroic adventures--Mitsuha instead immediately recognizes the lucrative possibilities of her new situation, and heads out to buy an arsenal of modern weapons. Her goal: to acquire 80,000 gold, and the life of leisure she's always dreamed of!

Get that 2 billion yen for an easy retirement! And look at that—there's a little cutie tagging along! Having lost her family to a freak accident, eighteen-year-old Mitsuha Yamano was left to fend against the harsh world all on her own. She was at a loss, thinking about her future, when a mysterious entity gave her the power to jump between worlds. How will she wield it...? While at times Mitsuha can be a huge ditz, she's a tough nut to crack. She begins using all the modern tools and knowledge at her disposal to carve her own path in this money-making fantasy set in a medieval world!

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!

Having completed their diplomatic delegation, Mitsuha and the girls finally get to go home…but there's no time for our heroine to relax! In Japan, she becomes a small business owner and also opens her first store on Earth: an art gallery café. In the other world, the viscountess ventures solo to the enemy land across the sea, and even launches another shop! “I am Nanoha, crosser of dimensions in the name of a wandering god! I cast open a path to another world!” Using her world-jumping ability, Mitsuha becomes an explorer of the New World, a spy, a sculpture artist, and more! There's no stopping her now! Business is booming in volume 4!
