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.

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.

As Sarada and the others hurry to evacuate the people of the island, Boruto grows anxious when he learns they are being threatened by the mobile fortress, which is equipped with a powerful weapon. Kagura, Hebiichigo and Kyoho show up to assist Boruto, Kawaki and Buntan. Together, they do what they can to destroy the weapon to protect their friends, but they are obstructed by Tenma and are forced to fight him.

There is a murder aboard the ship carrying the people rescued from Dotou Island, and Kyoho is the primary suspect based on the evidence. Despite his claims of innocence, there is no proof to back him up. Despite that, Kagura chooses to believe Kyoho. He places Boruto and Iwabe in charge of watching Kyoho while everyone else splits up into teams to search for any clues that may point to another culprit.

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.
