Kakashi uses his Summoning Jutsu and sends ninja dogs to track Naruto and Sasuke. With his newfound strength, Sasuke is serious about bringing down Naruto...
Sasuke quietly watches as Naruto sinks deeper in the water. He recalls the past, when the Uchiha clan was cruelly slaughtered.
Naruto is brought down by Sasuke's Fire Style: Fireball Jutsu, a jutsu passed down through generations of the Uchiha family.
Naruto tries desperately to change Sasuke's mind, but Sasuke is determined to go to Orochimaru. He tells Naruto that in order to surpass his brother, Itachi, power and hatred are necessary.
With the Curse Mark covering half his body, Sasuke is no longer the Sasuke of old. Naruto charges at this new Sasuke who has turned his back on his closest comrades.
Kimimaro succeeds in shattering Gaara's protective sand shield and attacks Gaara. Naruto finally catches up to Sasuke, who is racing to his destiny at Orochimaru's hands.
Kimimaro realizes that close combat is impossible against Gaara's wall of sand, so he moves further away for a long-distance attack.
Shikamaru, Kiba, and Lee are at the limits of their strength when Gaara, Temari, and Kankuro appear to assist their Leaf allies.
With Rock Lee there to take on Kimimaro, Naruto is free to chase after Sasuke, who has awakened.
Shikamaru succeeds in trapping Tayuya with his Shadow Possession Jutsu. But Tayuya moves to her Second State and fights back with enormous strength.
An injured Kiba and Akamaru barely escape from Sakon and Ukon. Naruto is locked in battle with Kimimaro...
Ukon, who is able to infiltrate the bodies of others, enters Kiba's body and tries to merge with his cells.
Shikamaru is determined to stop Tayuya, but she uses her Summoning Jutsu to call forth three giants. Meanwhile, on the plains, the battle between Kimimaro and Naruto is about to begin.
Akamaru sets explosives in the trees to trap Sakon. But an incensed Sakon turns the tables, and the explosives end up sending Kiba, Akamaru and Sakon off a cliff.
Naruto, Shikamaru, Kiba and Akamaru are in hot pursuit of Sasuke and the Sound ninja. Naruto and Kiba are upset that they have been unable to catch up and decide to try a surprise attack at night.
Naruto and his squad manage to catch up to Idate, only to find him hurt and unconscious with Aoi nearby.
The chief retainers think that Idate has made a farce of their great traditional festival. Jirocho believes that Idate has fled with some plan in mind.
Naruto, Sasuke, and Sakura are to protect the runners in a race being held during the Todoroki Shrine's ceremonial ritual held every four years.
Naruto and his two squadmates have always wanted to see what Kakashi looks like under his mask. The three do whatever they can to reveal his whole face.
After being advised by Tsunade to quit the path of the shinobi, Lee recalls his first meeting with his teacher Guy. Unable to master either ninjutsu or genjutsu, Lee has always been looked down upon by the others.
