Boruto and Konohamaru pay a visit to Remon's village, but are puzzled by Remon's cold demeanor. It turns out that Remon is a descendant of the Souma, a family that has protected the village from goblins for many generations. Thus, she is not allowed to leave the village freely. Furthermore, an important ritual is to be held shortly, so Kankitsu Akitsuki, Remon's childhood friend, imprisons her to prevent her from seeing anyone.

Kawaki has lost an arm in the battle against Delta, so he is given the prosthetic arm made for Naruto. Though the prosthetic can't move without Naruto's chakra, Naruto shares some of his chakra with Kawaki.

In order to save Boruto, Kawaki attempts a risky plan using a jutsu he only recently learned. While Kawaki and Sasuke fight a desperate battle, Naruto finally runs out of strength. As his consciousness fades, he and Kurama quietly reminisce about their past.
