Arc 50The Search for Naraku
Sasuke trained with Naruto to open a portal, then led Tsunade’s rescue team into the alternate space to find Naraku. They found him alive but trapped by an undetectable seal, and Tsunade left him in place while the team searched for a way to free him.
- Sasuke trained with Naruto’s Nine-Tails chakra until he could open a portal stable enough to carry the rescue team, while Tsunade prepared a backup plan and chose to lead the mission.
- Tsunade, Kakashi, Sasuke, and five Sealing Squad ninja entered the alternate space, while Naruto stayed behind to defend Konoha and Jiraiya maintained his Naraku disguise.
- Tsunade’s team searched the barren alternate space, then changed direction after Naraku used the Drums of Liberation to send tremors that revealed his location.
- Sasuke and a Sealing Squad ninja found Naraku in a valley, and Tsunade’s team confirmed he was alive but unresponsive, with his heart stopped and chakra nearly motionless.
- The Sealing Squad tried to identify Naraku’s seal, but its detection methods and Formula: Bright Eye revealed nothing.
- Tsunade decided not to move Naraku because the unknown seal might be triggered, authorized further investigation and access to the Uzumaki Clan’s old archives, and sent Sasuke to report back while Kakashi stayed to protect the group.
