Event Year: 2007

Kakashi continues to fight against Pain. With the arrival of Chouji and Chouza, things start looking up, but Pain's not out of tricks just yet.

Tsunade issues an order to call Naruto back to the village, but the elders do not trust her judgment on this issue. While Tsunade tries to convince them and prepares to join the battle herself, Kakashi fights Pain in an effort to figure out his abilities.

The Akatsuki Leader, Pain, begins his invasion of the Hidden Leaf Village. The Leaf ninja assemble to protect Naruto's whereabouts, but when Pain targets Iruka, Kakashi must face off against him.

Naruto succeeds in mastering his Sage Mode, taking it farther than even Jiraiya could. Things aren't looking so great for Konoha, however, as Pain prepares to make his move.
