Arc 5The Uchiha Empire at War
Seiichi united Konoha’s clans under the Uchiha Empire, strengthened the Uchiha, and arranged for the Tailed Beasts to turn against the invading alliance. Konoha’s forces defeated the Sand, Mist, and Cloud armies, while Seiichi began his confrontation with Iwagakure by wiping out most of its troops.

- Seiichi organized the empire’s forces and research, developed Divine Medicine, and saw the Uchiha gain dozens more Mangekyō Sharingan users as the Eight-Nation Alliance entered the Land of Fire.
- Seiichi and Kurama persuaded the other Tailed Beasts to help Konoha, then Seiichi sent his forces to meet the invading armies while Tsunade and Minato remained in Konoha.
- Hikari led the Uchiha ambush against Sunagakure, defeated and killed Rasa, and ordered her team to pursue the fleeing Sand ninja.
- Shisui and Itachi led the attack on Kirigakure, where the Tailed Beasts broke free of their Jinchūriki and the Uchiha killed Karatachi Yagura, Mei Terumi, and other Mist fighters.
- Fugaku’s forces fought Kumogakure as Matatabi and Gyuki revolted, and Raimei killed A, Killer B died, and Fugaku ordered the Uchiha to unleash their full power against the remaining Cloud ninja.
- Seiichi confronted Ōnoki and used Infinite Hole to absorb tens of thousands of Iwagakure ninja, then his Susanoo broke Kitsuchi’s earth walls and shattered Akatsuchi’s stone giant.
- Roshi and Han prepared to attack Seiichi’s forces but had to suppress their suddenly raging Tailed Beast chakra, while Ōnoki accused the Uchiha of orchestrating the attack.
