Boruto reawakens to find he’s back where he first found himself.

Sasuke is attacked by Meno, the guardian of the Observatory, and then poisoned. Just when he thinks it’s all over, he is rescued by Sakura, who has infiltrated the Observatory as a doctor. She gets Sasuke reassigned to assist her, and they begin their undercover investigation. From the intel that Sakura brings, they learn that Ultra Particles were what cured the Sage of the Six Paths, but in order to find out where it is located, they need to obtain a document called the Map of the Heavens. They decide to search the Observatory’s library for it.

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.

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!
