"The Great Battle of the Sealed Room!!" (密室の大攻防戦!!, Misshitsu no Daikō Bōsen!!, Viz: The Great Battle in the Sealed Room!!) is chapter 466 of the original Naruto manga.
The Fifth Mizukage assaults Sasuke with her Lava Release and Boil Release attacks. Already exhausted from his fight with the Fourth Raikage, Sasuke has difficulty enduring the destructive nature of her techniques. Zetsu begins to sprout from the Mizukage and her allies, giving their chakra to Sasuke. Rejuvenated, Sasuke tries to resume his search for Danzō. He is attacked by the Third Tsuchikage and apparently killed. Tobi appears and, carrying an unconscious Sasuke, proves this false. He offers to tell the Kage about his Eye of the Moon Plan.
