The ship carrying Boruto, his friends, and the people of Dotou Island is dead in the water. A shipbuilder Kajiki and his apprentice Ikada happen to pass by and offer to repair the ship at an island of shipbuilders where they live. Upon arriving on the island, Boruto and his friends try to do whatever they can to help while waiting for their ship to be repaired.
