Kinshiki and Momoshiki encounter Sasuke Uchiha, who had been traveling through another dimension to gather information on a threat greater than Kaguya Ōtsutsuki. In a blizzard of another dimension, Kinshiki engages in battle with his kanabō against Sasuke and his sword. Sasuke is nearly overpowered by Kinshiki's monstrous strength and barely escapes with his life.

Kinshiki and Momoshiki, as kinsmen to Kaguya, intend to capture the Nine Tails by kidnapping its' current Jinchūriki, Naruto Uzumaki. They appear during the Chūnin Exams in Konohagakure and start creating a chaos. Kinshiki destroys the arena and attempts to attack Sasuke and his daughter. Shikamaru Nara uses his shadow jutsu to restrain Kinshiki and Momoshiki but Momoshiki absorbs his power. Kinshiki fights Naruto and Sasuke, who combine their Tailed Beast Mode and Susanoo. However, Kinshiki and Momoshiki successfully capture Naruto when he allows himself to be caught in their jutsu to protect his son, Sasuke and Sarada.

They take Naruto to another dimension and bound him to begin the ritual of extracting Kurama from him. Sasuke, Boruto, and the four other Kage arrive to rescue him. Kinshiki fights against the other Kage and easily defeats them by imprisoning them in his jutsu. To everyone's horror, Momoshiki turns Kinshiki into a chakra pill and swallows him to increase his strength, prompting Naruto and Sasuke to fight him and have Boruto create a Ultra-Big Ball Rasengan to finish him off for good.
