Under the Starry Sky - S4.E74

The second stage of Naruto's training continues, while Tsunade sends out twenty teams composed of four ninja each to deal with the Akatsuki members in the Fire Country. Shikamaru leaves with Asuma, Izumo and Kotetsu, whereas Ino and Choji leave with Raido and Aoba. After putting in considerable effort, Naruto clears the second stage of his training, but collapses from hunger and exhaustion almost immediately afterward.
