Original Japanese title: Igai-sei Nanbāwan! (意外性ナンバーワン!).
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.
