Arc 3From Rescue to Command
Shin'un helped Hatake Sakumo escort Yakushi Nonō out of Sunagakure pursuit, then returned to Konoha and learned of his Senju ancestry. As the war intensified, Hiruzen Sarutobi promoted Shin'un to elite jonin and ordered him to lead reinforcements toward Nara Shikahito, while Tsunade asked him to take Nawaki along.
- Hatake Sakumo led Shin'un and a disguised team into a Land of Wind town to find Yakushi Nonō, then helped them escape when Da and Raku’s Sand Ninja surrounded them.
- Shin'un and his teammates fought off pursuing Sand Ninja, using his Lightning Release techniques and stored chakra to kill a Jonin before continuing to escort Yakushi Nonō toward Konoha.
- Hatake Sakumo and the Anbu reunited with Shin'un’s group, and they returned to Konoha, where Shin'un reunited with his parents before Suzume summoned him to the Hokage’s office.
- Hiruzen Sarutobi told Shin'un that his grandmother had belonged to the Senju Clan, and Tsunade took him to the Senju residence to receive secret medicine and meet the elders.
- The Senju elders confirmed Shin'un’s descent from their central branch, and Tsunade introduced him to Nawaki, who wanted to join the battlefield despite her wish to keep him safe.
- Shin'un tested the Senju Secret Medicine and found that it improved his chakra recovery and strength, then continued training with weights as the front-line situation worsened.
- Hiruzen Sarutobi ordered Tsunade to prepare Ibuse poison antidotes and lead reinforcements to Orochimaru, while promoting Shin'un to elite jonin and assigning him to lead over a thousand ninja to Nara Shikahito.
- Hiruzen Sarutobi sent Shimura Danzō and Root to the Land of Rain, while Tsunade asked Shin'un to take Nawaki to the Sand Ninja battlefield because she feared he would sneak to the front after she left Konoha.
