The second prince, Albert, and the seventh prince, Lloyd, of the Salum Kingdom are blown away to the present day by a torrent of magical power created by Lloyd's ``Spell Bundle'' that he chanted in his sleep. Just as they are at a loss in a land they don't know and a language they don't know, they are rescued by Natsume, a girl who runs away from home. Alberto, who was given one lodging and one meal, mastered Japanese overnight and quickly adapted to modern Japan. In order to find a way to return to my original world, I decided to work in this world!
