Kagura tells Boruto and the others of his plan to stop the enemy at a village on the route there. Everyone hurries to the destination, and it turns out Kagura lived in this village when he was little and has many fond memories of it. When Boruto and the others arrive, they try to get people to help them as they rush to prepare their plan to protect the village and the Hidden Mist!

Sarada, Mitsuki, and Boruto decide to meet with the Mizukage. Chojuro is heading into battle against the pirates, so Boruto and his friends ask the shipbuilder Kajiki for help. Thanks to Kajiki, they manage to reach Chojuro, but when they try to reason with him to stop the battle… Meanwhile, Ikada sails the raging seas with the intent to destroy the Shinonome 1, the brand-new power plant developed by the Land of Water.

Ignoring the danger to his own life, Boruto tells the other test subjects to escape while he takes on the person who may be working for Ouga. But they decide to stay and help Boruto fight the suspect.

As they search for Boruto’s whereabouts, Sarada and her team find themselves surrounded by skilled ninja and uncover unexpected information about the incident.
