Arc 15The Fourth War Begins
Kuro gained Six Paths power and prepared the allied forces for the final battle against Madara and Obito. After Hashirama was revived and empowered to face Madara, the Fourth Shinobi World War began, while Kuro's whereabouts and the true identity of his guiding jonin remained uncertain.
- Kuro awakened the Six-Tomoe Rinnegan, fought Madara, and helped the others escape the destruction of the Land of Whirlpools Island.
- At the Valley of the End, Sasuke immobilized Madara with Enma and Amaterasu, but Obito used Izanagi to save him and then withdrew with him.
- Kuro and the village leaders planned for war, and Kuro discovered Orochimaru's intelligence about the Demonic Statue of the Outer Path and Obito's hidden involvement.
- Kuro revived Hashirama and empowered him with the sages' Senjutsu and Slug's true body so he could hold Madara back.
- Madara and Obito prepared their forces as Kuro organized the allied army and began making Hashirama a weapon with Eternal World and a God Tree branch.
- Kuro's apparent guiding jonin, Uchiha Ryuichi, questioned him at the cemetery about mourning Kichitaro and Yoshiko, while White Zetsu concealed the real Ryuichi's corpse.
- Madara and Hashirama began their duel as Obito sent the White Zetsu and resurrected Uchiha into battle, and the Fourth Shinobi World War started.
