Even gods sometimes make mistakes. When two girls were born in different worlds at the same time, they mixed up their souls. The magically gifted one was left on Earth, and the “empty” one was sent to one of the magical worlds into the family of a duke.

It’s good when there are people nearby whom you fully trust. For the girl on Earth, that person was her grandmother—who arranged the exchange at the appointed time. But where will it lead? How will a child of the twenty-first century behave when she ends up in another world?
