Plot
Mitsuha Yamano is a high school orphan with little money from inheritance. Her college application was rejected and she lost her entire family in an accident. After being pushed off a cliff, Mitsuha accidentally gained the ability to teleport and travel between Earth and a medieval world from an interdimensional entity. Worried if she ever were to lose this ability and get stuck in either globe without retirement funds, she makes it her goal to exploit her power to exchange currency, jewelry, and Earth products while in the course of her exploration of the new world.
