Koji Kashin retreats from battle after seeing that Boruto has a "Karma" mark on his hand. Shortly after, Team 7 discovers a battle site where a boy lies unconscious. Much to everyone's shock, the boy possesses the same mark as Boruto.

During the battle against Funamushi, Kagura is fatally injured. Boruto becomes enraged and charges at Funamushi, activating his Karma. When the Funato squad retreats, Kagura gives Boruto and the others one final request.

Boruto and his friends manage to triumph over Funamushi, but they aren’t able to savor the victory. Everyone is having a difficult time believing Denki and Iwabe are still alive days after being captured. Meanwhile, Boruto discovers a hidden side of Funamushi when he is targeted by people who looked up to the pirate, as revenge begets more revenge. Boruto has always continued to push forward until now, but this causes him to question the point of fighting.

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.

Kawaki and Himawari participate in a training session in the forest near the academy. The class is split into three-person teams and Kawaki ends up on a different team from Kae. Anxious about losing sight of Kae, Kawaki is unable to focus and ends up burdening his assigned team. Kae is lured away by a mysterious person and disappears. Fearing that she is in danger, Kawaki and Himawari rush to find her.

Hana, who has recovered from her injuries, and Kawaki, who is back guarding Kae, return to class. Life at the Academy gradually goes back to normal. Meanwhile, Hana learns that about the attempt made on Kae’s life and regrets her inability to prevent it. She returns to the scene of the incident to recount what occurred.

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.

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?!

While everyone is exhausted from Ouga’s experiments, a test subject talks about their goals, which leads everyone to talk about what they want to do if they survive. The mood is lightened, but Ouga begins a new experiment. Due to the careless actions of certain test subjects, everyone's lives are in danger once again.

Naruto falls ill, and Sasuke goes to the Tatar Observatory to try to find a cure.

Sasuke and Sakura work together to gather information concerning the Ultra Particles. Unfortunately, there is still much they don’t know, and they are unable to figure out where to get answers. Eventually, Sasuke finds a clue to the whereabouts of the Ultra Particles from something his cellmate mentions. Meanwhile, Sakura discovers a hint to unraveling the mystery of the Map of the Heavens from a game called Star Lines. Having finally gathered the information they need, Sasuke and Sakura try to obtain the Ultra Particles. However…

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.

Boruto arrives to help Kawaki defeat Code. In order to match Code’s incredible combat abilities, Boruto activates his Karma. In response, Code activates his own Karma. As the battle intensifies, Kawaki becomes worried that Momoshiki might take control of Boruto’s consciousness. Meanwhile, in the Hidden Leaf Village, Boruto and Kawaki had disappeared without anyone noticing. Naruto decides to do his own investigation to find out where they went.
