Arc 9The River of the Undying
Naruto prepared to face Obito by mastering new powers, gathering the Hokage, and awakening souls in the Six Paths tools. At the River of the Undying, Naruto fought Obito and Tsuchima, who revealed himself as Kaguya’s will, while Obito sent Naruto Namikaze into the Realm of Nothingness.
- Naruto moved Hell Valley to Amegakure, trained for his battle with Obito, and later used Kotoamatsukami so often that his eyesight failed.
- Kabuto and Sasuke found Kokusho Senju, but Naruto confronted them and took Kagami Uchiha’s left eye after a fierce battle with Kabuto and the reincarnated Might Guy.
- Naruto transplanted Kagami’s eyes, awakened the Eternal Mangekyō Sharingan, and had Orochimaru reincarnate Hashirama, Tobirama, Hiruzen, and Minato with strengthened souls.
- Naruto asked the four Hokage to keep Madara, Kabuto, and Sasuke from interfering, then gave souls to five ninja tools and agreed to fight Obito at the River of the Undying.
- Naruto and Obito began their battle as Tsuchima Senju joined Obito, while the Hokage and Konan watched from above the river.
- Naruto outmaneuvered Tsuchima, created a younger brother through a reincarnated clone, and fought Tsuchima’s Perfect Susanoo with his own Susanoo and a sentient tomoe army.
- Naruto wounded Tsuchima with the Sword of Great Sun Shakugi, but Tsuchima escaped and revealed that he was Kaguya Ōtsutsuki’s will.
- Obito sent Naruto Namikaze into the Realm of Nothingness, took the Amber Purifying Pot, and challenged Naruto Uzumaki to fight without Flying Thunder God as a clone emerged from the pot.
