Arc 4The Dragon Vein and Succession
Shinichi and Tsunade traveled through time, freed Rōran from dependence on the Dragon Vein, and returned to their era with Shinichi gaining powerful new eyes and abilities. Shinichi became Uchiha Clan Head, took Nawaki and Minato as apprentices, and ended the arc sharing a quiet moment with Tsunade.

- Shinichi and Tsunade created forests and waterways that transformed Rōran into an oasis, and Shinichi absorbed the Dragon Vein’s chakra.
- Shinichi fused the stolen eyes into his Rinne Tenseigan and spent months mastering chakra modes, developing Hydrogen Release, and preparing the Uchiha Clan for war.
- Shinichi accepted Nawaki as his apprentice, revealed his new eyes to Mito Uzumaki, and promised to protect Tsunade and make her happy.
- Shinichi persuaded Raishin to step down as Uchiha Clan Head, adopted Minato as his disciple, and planned to protect him from the fate he remembered.
- The Great Toad Sage warned Jiraiya that a Devil Child would destroy the shinobi world, while Hagoromo directed Jiraiya toward Shinichi.
