Boruto opens a portal and transports Isshiki and himself to another dimension. Naruto and Sasuke follow them, and the final battle against Isshiki begins.

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.

Kae has been taken away and Kawaki must face a dangerous assassin. Himawari acts as his partner and provides support during the battle. They try to corner the enemy with coordinated attacks, but the enemy proves to be powerful. Meanwhile, their classmates, who had entrusted Kawaki and Himawari to directly confront the assassin, take action in a desire to try to help. Will Kawaki be able to save his precious friends and accomplish his mission?

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?!

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