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!

No matter how out of control things get, Mitsuha keeps her cool, turning every hurdle into a business opportunity.

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

Kaoru had been granted cheat powers that allows her to create potions at will. But using her potion powers wherever she goes is hardly inconspicuous.

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?!
