Naruto has been pulled into a different dimension by Jigen. There he encounters Sasuke, who tells him that Jigen is a dangerous person and that they must do whatever it takes to defeat him immediately. Naruto and Sasuke work together to defeat Jigen in a fierce battle, but they struggle against Jigen's advanced fighting abilities and mysterious jutsu. Meanwhile, Boruto gets a bad premonition when his Karma starts acting up, and so he quickly returns home with Mitsuki. Kawaki and Sarada are there, worried about Naruto's safety.

Boruto, Sarada, Mitsuki, and Kawaki arrive at the dimension that Naruto is trapped in, but Boro is there waiting for them. The four create a team with Sarada leading them to fight Boro, who uses a black mist to paralyze his enemies.

Naruto and Sasuke are greatly overwhelmed by Isshiki's abilities. As a last resort, Kurama offers Naruto a chakra mode called Baryon Mode, which grants him immense power. The intensity of this power, however, could end his life.

Cho-Cho is injured in an attack by a mysterious ninja and the item that Mozuku had been holding is stolen. Captain Shikadai realizes that this was no ordinary guard mission, but one that makes them the targets of other ninja. He immediately decides to turn back toward home. But Kawaki feels for Mozuku, who was entrusted with the item that would save his people, so he ignores Shikadai's orders and pursues the ninja along with Mozuku. All alone, Kawaki faces a powerful enemy who uses a strange jutsu. Will he be able to protect Mozuku and safely return him to the Land of Calm Seas?

In retaliation against Boruto and his friends for destroying Tenma’s mobile fortress, the pirates land on the Isle of Shipbuilders. Funamushi, a follower of the Funato Clan, attacks Kagura, hoping to capture him alive so that he can use him as a bargaining chip. Kagura fights back using the Hiramekarei—the twin swords that the Sixth Mizukage Chojuro entrusted to him—but Funamushi is a formidable foe. Meanwhile, Seiren appears before Boruto and torments him with her persistent attacks. Can Boruto find his way out of this predicament?!

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 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.

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.

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.
