In spite of being badly beaten on by Kabuto, Naruto uses a Kage Bunshin and pulls off a perfect Rasengan and sends Kabuto flying into a large rock. Before getting hit, Kabuto taps Naruto's chest with his chakra scalpel trick, severing the flow of chakra to his heart. Naruto collapses and Kabuto appears to have survived the worst of the Rasengan, thanks to a Regeneration Jutsu, however, the damage was far worse than he thought and Kabuto faints for the time being. Tsunade rushes over to Naruto to try and save him, but Kabuto mocks her, saying it's too late for her to save him. Inside of Naruto, Kyubi feels a darkness surrounding him, and with the splash of a tear, he saves Naruto's life. Tsunade is shocked to see Naruto reaching up, claiming the necklace she bet him.
Meanwhile, Orochimaru and Jiraiya are still fighting, when Orochimaru notices Tsunade trying to save Naruto, he breaks off his fight with Jiraiya and closes in to kill Naruto. Tsunade saves Naruto several times from Orochimaru's blade in the mouth jutsu, before knocking him silly with her freakish strength. Say tells Orochimaru that she WILL protect Naruto and the Hidden Leaf village, for she is the 5th Hokage. Releasing some seals, Tsunade completely heals herself and prepares to take Orochimaru down.
As the episode closes, all three of the Sannin have summoned their special creatures: Jiraiya summoned Gamabunta, Orochimaru/Kabuto summoned Manda, the horned black mamba, and Tsunade summoned Katsuya, a giant slug.
