Arc 3The Whirlpools’ Buried Past
Kuro explored the Uzumaki ruins, absorbed the ocular power sealed there, and relived the history of Indra, Asura, Ori, and the origins of the Uzumaki Clan. Back in the present, he confronted Orochimaru after the rogue attacked Jūzō Biwa and Kimimaro, then used his Mangekyō Sharingan to bring Orochimaru under control as a masked man appeared.
- Kuro uncovered the ancient Uzumaki ruins with Mei Terumi, absorbed the ocular power concealed behind a mural, and learned the Eternal World technique while receiving visions of the past.
- Kuro witnessed the rise and fall of the Ninjutsu School and Ninja Sect, then saw Ori become a crimson monster and devastate their forces.
- Kuro watched the Demon Slayer Corps forge Kagutsuchi and seal Ori beneath the Land of Whirlpools, where Kuro died guarding the seal and the Uzumaki Clan’s ancestors remained behind.
- Back in the present, Kuro considered seeking Orochimaru’s help before Obito told him Orochimaru had left Akatsuki and was heading toward Kimimaro’s mission.
- Orochimaru attacked Jūzō Biwa, but Kimimaro protected him until Kuro arrived and sent Orochimaru flying with Hiramekarei.
- Kuro fought Orochimaru with Hiramekarei, mist, and bone techniques, then revealed his Mangekyō Sharingan after Orochimaru restrained him.
- Kuro used his Mangekyō Sharingan to strip Orochimaru of self-awareness and ordered him to wait outside Mist Village, while a masked man emerged from a spatial vortex behind Kuro.
