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.

A young high school graduate who lost her parents and beloved older brother in an accident. After being pushed off a cliff, she discovers that she has accidentally gained the ability to travel between two worlds, the ability to understand and speak the alternate world's language, and vast regenerative abilities from an interdimensional entity. She can also take objects and other people with her at will. Using this new advantage, she begins importing modern items from Earth to make her way in the other world and earn her own retirement funds. She also opens a store to serve the other world's residents. In the other world, she claims to be a noble named Mitsuha von Yamano and that she fled her home country due to a succession crisis.
