- Uchiha Gen returned Shukaku’s Tailed Beast Bomb to zero, subdued him, and declared Pakura Sunagakure’s Fifth Kazekage after rejecting her proposal to kill the survivors.
- Uchiha Gen and Gengar altered Sunagakure’s inhabitants’ memories, and Gen planned to use the village’s influence to replace the daimyo system before joining the war against Iwagakure.
- Ōnoki learned that Iwagakure faced attacks from several villages and ordered Kitsuchi to test whether the Clay People could inherit his Dust Release, while Hiruzen Sarutobi discovered that Danzō’s peace-treaty meeting had been a Dream Clone.
- Tobirama Senju and Uchiha Izuna traveled through time, met Hashirama Senju, and learned that their Shinobi World was a projection and that Madara Uchiha and Indra planned to merge 487 worlds to rewrite its Will.
- Uchiha Gen left Sunagakure with Uchiha Hikari to seek Iwagakure’s tailed beasts and the Raikage, while Kakashi Hatake, Obito Uchiha, and Rin Nohara began a mission against Kirigakure.
- Hatake Sakumo stopped the Third Mizukage and killed him, but Madara Uchiha confronted Kakashi, Obito, and Rin on the island and left Kakashi unconscious while immobilizing Rin.
- Six Paths Obito told Obito that Madara’s plot had killed Rin in another world, and Obito awakened the Mangekyō Sharingan before accepting the Ten-Tails’ chakra and becoming its Jinchuriki with Rin’s help.
- Obito sent Rin and Kakashi into his Kamui dimension and fought Madara in the Naruson Domain, using Izanagi to recover from repeated fatal blows and attacking with Amenonuhoko.
