Synopsis
Tsunade meets with Orochimaru, though rather than heal him she tries to kill him. Unwilling to see her loved ones if it would mean the destruction of Konoha, Tsunade is drawn into battle with Orochimaru's assistant, Kabuto Yakushi. Kabuto is eventually able to immobilize her, forcing the newly arrived Jiraiya and Naruto to defend her; Jiraiya battling Orochimaru and Naruto fighting Kabuto. Although Kabuto appears in control of the battle, Naruto is able to deliver a perfected Rasengan to his stomach in an attempt to protect Tsunade. Inspired by Naruto's winning of their bet, Tsunade overcomes her restraints and joins Jiraiya in attacking Orochimaru. Unable to do combat with both of them, Orochimaru escapes with Kabuto. Once Naruto recovers, Tsunade decides to accept the title of Hokage, and returns with him and Jiraiya to Konoha.
