240

Boruto and Ikada get to know each other while sailing to the island. Sarada informs Mitsuki and Team Denki of the escalating situation, which forced Chojuro to go to the front lines against the Funato clan. Ikada's boat runs into a shipwrecked man, and he jumps out to save them at Boruto's behest. As he watches Ikada rescuing them, Boruto realizes that Ikada was the one who rescued him as well. They manage to escape the rough seas and reach the island. Meanwhile, Isari tells Araumi about the Mizukage's gathered fleet, but Araumi is confident that his daughter Seiren can win the battle against him. Ikada and Boruto return to Kajiki with the part and they're able to fix the ship's engine. Seiren closes in on their island, aiming to bring her little brother, Ikada back into the fold.
