Arc 14The Fourth Great Ninja War
Ueno Kei and the Five Kage faced Tobi’s declaration of war, while Ueno Kei protected Naruto and arranged for him to train with Killer B. As Naruto learned to control the Nine-Tails’ chakra, Ueno Kei confronted his inner self, uncovered Kisame’s intelligence, and learned that several threats were converging around Kaguya and Obito.
- Sasuke fought the Fourth Raikage until Ueno Kei intervened, defeated Sasuke, and confirmed the truth about the Uchiha massacre.
- Tobi transported Sasuke and Hawk away, revealed the Eye of the Moon Plan, and declared war after the Five Kage rejected his demand for the Eight-Tails and Nine-Tails.
- The Five Kage formed the Allied Forces, and Ueno Kei returned to Konoha before taking Naruto to a secret refuge shared with Kumogakure.
- Naruto defeated Shizuka in their arranged duel, urged her to choose her own future, and helped her face her grief before Kabuto attacked.
- Kabuto offered intelligence in exchange for Itachi’s corpse, but Ueno Kei refused and drove him off after Kabuto summoned reincarnated shinobi.
- Ueno Kei and Naruto reached Kumogakure’s giant sea turtle, where Killer B began training Naruto and Ueno Kei faced and destroyed his dark counterpart beneath True Falls.
- Ueno Kei exposed Kisame’s disguise and learned about Akatsuki’s forces, the stolen Rinnegan, and Kisame’s suspicion that Tobi was Uchiha Obito.
- Black Zetsu encountered Momoshiki’s group while Obito enlisted Moryo, and Naruto emerged from training having met his mother as Ueno Kei sent him to handle an urgent matter before joining the battle.
