Season: 20

Hagoromo's two sons, Ashura and Indra, share a happy childhood, training and playing together. Indra is naturally gifted with great talent, and at a tender age is nicknamed the “genius of Ninshu.” On the other hand, Ashura has no aptitude for Ninshu. Still, the two boys are very close. But Hagoromo is unaware of the malevolent power stirring in the shadows…

The Infinite Tsukuyomi does not affect Hashirama, Tobirama, Hiruzen and Minato because they are reanimated. Hagoromo, the Sage of the Six Paths, appears and explains to the four that Hashirama and Madara are the reincarnations of his sons Ashura and Indra. Hagoromo recounts the tale of how he founded Ninshu, the Ninja Creed, and about the lives of Ashura and Indra.

Black Zetsu reveals that he masterminded and influenced all the events from the end of Ashura and Indra's era to the current Fourth Great Ninja War. Naruto rejects Black Zetsu’s claim that the entire history of shinobi was solely for the resurrection of his mother, Kaguya. Naruto and Sasuke work together to seal away Kaguya, but they can't find a way to counter her.

Kaguya is furious that Hagoromo has broken the law. Hagoromo finds out what Kaguya did in the past and makes up his mind to fight her. Knowing nothing about her, Hagoromo cannot trust her—he wonders if the love and the despair she experienced are the sole cause of her anger. Unable to reach an understanding, mother and sons begin their long, sad battle.
