The final round of the Chunin Exam is announced. Many of Boruto’s classmates who didn’t advance to the final round of the last exam have made it this time. Also, the rules of the exam have changed: the use of Scientific Ninja Tools of your own creation is now allowed!

Cho-Cho is injured in an attack by a mysterious ninja and the item that Mozuku had been holding is stolen. Captain Shikadai realizes that this was no ordinary guard mission, but one that makes them the targets of other ninja. He immediately decides to turn back toward home. But Kawaki feels for Mozuku, who was entrusted with the item that would save his people, so he ignores Shikadai's orders and pursues the ninja along with Mozuku. All alone, Kawaki faces a powerful enemy who uses a strange jutsu. Will he be able to protect Mozuku and safely return him to the Land of Calm Seas?

Boruto joins Ikada as he sails to a factory where they can get a component needed for ship repair. He is impressed by Ikada’s excellent piloting abilities. Ikada reveals that he left home despite the protests of his family to look for work that involved ships. That was when he met Kajiki and found his dream of becoming a great ship carpenter. They spot a ship that has been in an accident, and while working together to save the passengers, Boruto sees something unbelievable.

Boruto and the others return safely to the Leaf Village. While Naruto informs Team 7 of events that have occurred in the Hidden Mist since they left, Boruto and Kawaki get into an argument over whether or not Ikada should be punished.

Tsuzura’s hawk has suddenly been sold, so he does what he can to get his precious bird back. Hearing what happened, Boruto ignores Sasuke and rushes to help.

Code worships Isshiki Otsutsuki, who was defeated by Boruto and his friends. In order to meet a certain person, he visits the facility that formerly belonged to Boro. Like Kawaki, Code miraculously survived the experiments intended to help select a vessel for Isshiki—and he possesses greater power than even Jigen. He has vowed revenge against Boruto and Kawaki for destroying Isshiki.

Meanwhile, Claw Marks left by Code are discovered just outside of the Hidden Leaf Village. While the Hokage and the others take precautions, Boruto proposes an idea to Kawaki.
