The showdown between Team 7 and Ao begins. Team 7 works together to bring Ao down with various attacks and jutsu, but he proves to be a difficult adversary due to his use of scientific ninja tools.

Kawaki watches a Shinobi Hand-to-Hand Combat match between Naruto and Boruto. Boruto uses his specialty, the Shadow Clone Jutsu, to take on his father, but he struggles. Upon seeing this, Kawaki tells Boruto to use the power of his Karma. Meanwhile, Kawaki becomes interested in the Shadow Clone Jutsu that Naruto and Boruto like to use.

Konohamaru and Sai are given a mission to infiltrate Boro's cult in order to obtain information on Kara and its whereabouts.

The match between Sarada and Cho-Cho begins. Kawaki has been invited by Naruto to observe, as well as Shinki and others who have come from the Hidden Sand Village. Who will emerge victorious in a battle between best friends?!

The Land of Water is taken over by pirates, and contact with Denki's Team 5 is lost. The new Team 7 joins up with a unit led by Kagura and sets out for Dotou Island to assist Team 5 and rescue the islanders. However, the unit is made up of Buntan, Hebiichigo, and Kyoho, who in the past had called themselves the “New Seven Ninja Swordsmen of the Mist.” Sarada and Mitsuki go ashore to scout the island while Boruto and the others stay back and watch the situation nearby.

As Boruto and the others ready their plan, they learn that one enemy unit is heading to the village ahead of the rest. Since they haven’t finished making preparations, the village will be in danger, so they hurry to evacuate everyone. Kagura worries that they won’t have enough people to fight. Just in case, he releases the curse placed on Buntan, Hebiichigo, and Kyoho, temporarily setting them free. Hesitantly, they agree to fight alongside Kagura and Boruto.

Boruto’s desperate attempts to reason with Ikada fail and he’s unable to change his mind. He prepares himself to give his life to stop the Land of Water and the pirates from fighting. He tells Sarada and Mitsuki that they should not seek revenge if he ends up dying. However, neither of them is able to stand idly by. Will Boruto and his friends manage to stop this cycle of revenge and restore peace to the seas?!

Kawaki and Himawari’s class goes on a field trip to an uninhabited island in order to create new memories with Kae. Because of its distance from the village, there are all sorts of rumors about the island, and bizarre incidents occur, like the disappearance of the food they brought. The field trip suddenly starts to feel unsettling, but under Hana Sensei’s direction, the students try to work together to overcome these difficulties. Meanwhile, Kawaki suspects the assassin targeting Kae might be lurking nearby, so he steps up his watch.

Boruto dozes off on Thunder Train and wakes up in an unfamiliar location along with the other passengers. A mysterious individual known as Ouga forces them to participate in a game of death disguised as an experiment—who will successfully beat this game and make it out alive?!

Boruto makes a desperate decision to prevent Momoshiki from taking over his consciousness again. Meanwhile, Kawaki drives back Code using the Karma that Amado revived. Willing to do whatever it takes to eliminate anyone who is a threat to Naruto, Kawaki fights with overwhelming power. Shikamaru is shocked by his strength, and Code learns the difference in their powers. Boruto and Kawaki have overcome various obstacles as brothers, but a troubling shadow begins to loom over their relationship. As Momoshiki once said, the fateful moment that will take everything from Boruto is approaching!
