At the suggestion of Shino Aburame, their homeroom teacher, Boruto and his classmates split off into gendered teams to capture flags placed on the roof. Boruto and the rest of the boys' team quickly head for the roof, but they struggle with traps and the girls' team, led by Sarada Uchiha and Chocho Akimichi. Desperate to capture a flag before the girls' team, Boruto tries out a Summoning Jutsu, but he ends up summoning something unexpected!

Cho-Cho's scared because she thinks she's being watched by someone, so she decides to catch them in the act. She succeeds in snagging Magire Kakuremino, and it turns out he wasn't watching Cho-Cho, but Sumire, the class rep, whom he secretly likes. Cho-Cho urges him to declare his love, and at first Magire hesitates. But he takes the leap and tells Sumire how he feels!

As Naruto sleeps, Kawaki repairs the vase he broke. Suddenly, Kurama, the Nine-Tailed Beast, appears before him. Kurama has been living with Naruto since he was sealed within him and tells Kawaki that Naruto used to be just like him. Upon hearing about Naruto's life, Kawaki aspires to become just like him. He reaffirms his decision to work with Boruto, who is also branded with a Karma, to defeat Jigen and the Kara.

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

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.
