The Hokage battle begins, with Hashirama's Wood Style giving him and his brother the advantage on Hiruzen as he summons Enma to help him in the uneven fight as Orochimaru brings out his Kusanagi sword. During the fight, Hiruzen learns that ninja brought back by the Reanimation Jutsu are immune to any normal form of attack and regenerate from any injury dealt on them. At that time, explaining his desire to become immortal to know every form of ninjutsu, Orochimaru decides to reveal the fruits of his labor by peeling away his face: revealing the face of a girl whose body he now occupies.
