Near the Divine Tree is an area known as the Peak of Demise. No one is allowed to go near it, except those chosen by Kaguya to undergo a ritual she has established. Gamamaru, a Sage Toad, says the truth lies beyond the peak—those words stir Hagoromo's curiosity, and he decides to head out to investigate.

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.
