Ch. 521The Final Plan
Kangetsu revealed that he had controlled the events leading to Kaguya Otsutsuki’s revival and had deliberately used Impure World Reincarnation to leave her resurrection incomplete. He demanded her help and revealed that Madara’s Rinnegan, still held by Black Zetsu, had changed.
- Black Zetsu explained how Uchiha Kangetsu had thwarted him and wounded him before the current era began.
- Kangetsu used Impure World Reincarnation to stop Madara’s body from swelling and complete Kaguya Otsutsuki’s emergence.
- Madara demanded to know whether Kangetsu had known about the plan, and Kangetsu said he had controlled Black Zetsu’s actions and weakened Kaguya’s resurrection.
- Kangetsu told Kaguya Otsutsuki that he needed her help, while Black Zetsu insisted she would never help him.
- Madara’s Rinnegan emerged from Black Zetsu, its surface now blood-red.
