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.

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.

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!
