Naruto Shippuden · Fourth Shinobi World War: Countdown

Naruto catches up to Sasuke right after he wounds Sakura, and the two clash until they meet in a mental space. Sasuke swears to destroy the Hidden Leaf to clear the Uchiha name; Naruto says he's ready to die in their final fight. Tobi whisks Sasuke away. Back in Konoha, the team confirms Danzō is dead, and Kisame turns out to be alive, hiding inside Samehada. The feudal lords make the Allied Shinobi Forces official, Tsunade wakes up and is Hokage again, and the Great Toad Sage predicts Naruto will face a young man with powerful eyes. In the end, Kabuto offers Tobi an alliance and shows off ninja brought back from the dead, like Itachi and Nagato. The Kage decide to hide Naruto on an island.
