Black Zetsu observes Indra and Asura training and senses a potential darkness in Indra. As time passed on, Hamura passed on after working hard to spread Ninshu. After Hamura died, he chakra and passion remained strong enough for him to defeat Enma Daioh in the afterlife and become the Shinigami. As Hagoromo reached the end of his life, he named Asura his successor despite both his and Indra's opposition. Black Zetsu took this chance to tempt Indra into causing a rebellion, introducing him to various ideas such as Horcrux. Indra then kills Hagoromo, who was weakened by the previous extraction of the Ten-Tails. Black Zetsu looks on, telling Kaguya that it has finally started their revenge.
