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. Meanwhile, in the seas near the Land of Water, a clash between the pirates of the Funato Clan and the Land of Water is becoming unavoidable.

That's why this nation never had any unity.
.لهذا لم يكن لهذه البلاد أيّ ترابط
Deshalb war dieses Reich
noch nie vereint.
No somos un país homogéneo.
No somos un país homogéneo.
Per questo il nostro Paese 
non è ancora davvero unito.
Por isso, nunca houve muita união por aqui...
Поэтому у нас и нет никакого единства.
