An urgent message from the Sand Village detailing the Akatsuki’s kidnapping of the Kazekage reaches the Hidden Leaf Village. Tsunade wastes no time in ordering Team Kakashi to the Sand Village.

Chiyo and Kakashi realize that the attack was just a diversion, and that the Akatsuki have already begun the process of extracting the Tailed Beast from Gaara.

Sakura counters the Iron Sand attack of the Third Kazekage puppet with superhuman strength.

Gaara and his rescuers make a triumphant return to the Hidden Sand Village.

Immediately after Yamato signals Naruto and the others out to the bridge where Orochimaru and Kabuto are waiting, Naruto's chakra begins to boil with the chakra of the Nine-Tailed Fox. Slowly, Naruto grows more tails as Orochimaru taunts him and makes him even more angry. Meanwhile, Yamato remembers Jiraiya speaking of how many tails he has seen Naruto grow. Jiraiya explains more about what happened and more about how Naruto acts when he's in his Nine-Tails form.

Yamato and the team enter Sai's room and confront him while Kabuto makes his way there as well. Sai tells Team Kakashi that not only was he to help with Konoha's destruction but also act as a spy against Orochimaru. Yamato reveals the secret of "Root"- its members were trained like Kirigakure's students in that they had to kill their friends so as to eliminate their emotions. Sakura returns Sai's book to him, remarking that he still has emotions because he treasures it. Sai then tells the group about his bond with his brother. Finally the team decides what to do about Sai's betrayal outside the lair. In doing so, Naruto tells the group about his own bonds and about how far he's willing to go to bring Sasuke back.

Naruto and his clones continue to work on chakra nature manipulation by slicing leaves. After some struggling, Naruto approaches Asuma, who is also a wind type, for advice, after which Asuma gives Naruto's clone a few pointers. Naruto is subsequently able to slice a leaf in half. Asuma and Yamato head out with their teams on new missions. It is revealed that Asuma is the Third Hokage's son and that he is in a relationship with Kurenai. Meanwhile, on a hill overlooking a burnt village, four cloaked figures discuss the awakening of the Fire Country by eliminating the Leaf Village.

Danzou is brought in for questioning after being caught meeting with a young Rain ninja. Sora confronts Asuma, and Asuma admits to having killed Kazuma. He attacks Asuma, his arm once again assuming a demonic form. Afterward, Naruto gets injured while shielding Sora from the attacks of an unknown individual, presumably from Root. Furido then approaches Sora, telling him to kill both Asuma and the Hokage to avenge his father. Later on, Naruto catches Sora going after Tsunade. Sora retreats as Shizune and a few other ninja arrive, but Naruto pursues him. At that moment, a mysterious lightning storm strikes, cutting off power to the entire village.

Asuma apologizes at the grave of the Third Hokage for not understanding his advice concerning what the "king" of the Fire Country is. At the hospital, Naruto and Sai recover, despite Naruto's desire to resume his training. Tsunade receives a report from Kakashi that Akatsuki is on the move. Elsewhere, Yugito Nii, the Two Tails Jinchūriki, struggles against Hidan and Kakuzu and unleashes the Two Tails, but is defeated and captured. Hidan and Kakuzu then turn their attention to the Fire Country for their next target.

A call from the Akatsuki leader forces Hidan and Kakuzu to fall back, but in the wake of the aftermath, not everyone makes it back to Konoha alive.

Naruto challenges Kakuzu with his new technique, the Rasen Shuriken, but can he defeat Kakuzu when his technique isn't even complete yet?

In the aftermath of the battle, Teams 7 and 10 return to Konoha. After examining Naruto, Tsunade officially classifies Naruto's new technique as a Forbidden Jutsu and warns Kakashi never to let him use it again. What is the terrible secret of the Rasen Shuriken that has left even Tsunade stunned by its power? Meanwhile, Orochimaru orders Kabuto to search for a woman who will help him reach his goal.

Naruto successfully breaks down the crystal labyrinth with his new jutsu and he and the rest of Team Kakashi come to Kakashi, Kiba and Shino's aide, and rescue Hinata as well. Meanwhile, Kabuto, Guren, Yukimaru and Gozu head to the lake Kabuto and Yukimaru went to before. What could be in the lake that Orochimaru wants?

The sealing unit prepares the sealing barrier and the other two teams go into battle with Guren and her henchmen. Kakashi, Naruto and Sai stall Guren and Gozu while Shino prepares to go against Guren's crystal style. Meanwhile, Lee goes against Guren's other henchmen and gets trapped in their smokescreen. Can Lee find a way to defeat them?

Orochimaru reveals the true, hideous form his body has taken from years of experimenting on his body. Can Sasuke defeat this menacing form, or does Orochimaru still have a few tricks up his sleeves?

Kakashi splits the two teams into five separate groups, each aided by a couple of his ninja dogs, in order to locate clues about Itachi and Sasuke's whereabouts. Unbeknownst to everyone, familiar foes have set their eyes upon both Naruto's group and Sasuke.

Having suspicions about the Nine-Tails' attack on the Hidden Leaf Village years ago, Jiraiya tells one of his frogs that the time may come when Naruto will need to access the fox's full power. His interrogations finished, Jiraiya sets out in search for Pain, but winds up encountering Konan instead. Is there a connection between Jiraiya, Konan, and the mysterious Pain? Elsewhere, one of Naruto's shadow clones runs into Team Hebi.

Pain's God Realm finally enters the battle. As Naruto's toad allies fall one by one, the situation begins to look grim. Can Naruto defeat Pain?

Deciding to believe in Naruto, Nagato uses the Gedo Art: Rinne Rebirth jutsu, expending the last of his chakra, and thus giving his life, to revive every person in the village who died in the attack, saying that it's the least he can do. With Nagato dead, Konan leaves Akatsuki, taking Nagato and Pain's God Realm (who is actually the body of Yahiko) with her, parting with Naruto saying that since Nagato believed in him to achieve true peace, she will as well. As Naruto returns to the Leaf, he is astonished to find the entire village awaiting his return, hailing him as a true hero. After all these years, Naruto has finally received the acknowledgment he's always wanted.

Kakashi has a flashback back when he was assigned to be the sensei of Team 7. In a bid to know his students, Naruto, Sasuke & Sakura, better, Kakashi spies on them and to see how they would all get along as a group. Angered by Sakura's talk about calling Naruto a brat and that he has no family to tell him right or wrong, Sasuke tells Sakura she is annoying. Realizing Sakura's sadness, Naruto goes to battle Sasuke, but gets defeated. It then goes back to the present and Kakashi claims that it is up to him to stop Sasuke.

In the past, Naruto and Sakura joined Sasuke on a mission to collect the paw print of Nekomata, a large and powerful two-tailed ninja cat that ruled over all of the ninja cats.

Sasuke has a flashback while traveling to Konoha with his team, Taka. He once saved a girl named Naho not knowing that she's a relative of the Feudal Lord. Meanwhile, Naruto and Sakura are sent on a mission to accompany Naho and act as her bodyguards while Kakashi and Sasuke are sent to discover the reason why internationally wanted bandits have entered their border. Kakashi and Sasuke later find out that the bandits intend to abduct Naho. Naruto and Sakura are defeated by the bandits and are taken hostage. Sasuke finds them first and proceeds to defeat the leader and mercilessly punches him because of his jealousy for Naruto's growing power. A cut to the present reveals Naruto contemplating on his promise to have Sasuke return to the village.

Sakura, not wanting to cause Naruto any more pain, tells him that he can let go of his promise about bringing Sasuke back, and claims that she doesn't feel anything more for Sasuke. To top it off, Sakura confesses her feelings for Naruto, taking everyone by surprise. How will Naruto respond? Meanwhile, Kisame tracks down Killer Bee and the battle for the Eight-Tails begins.

Three years ago, Leaf Anbu Yugao Uzuki lost her lover Hayate Gekko in battle. Unable to cope with his death, Yugao has since left the Anbu and joined the Medical Corps. Meanwhile, Kabuto has reanimated Hayate.

Kabuto reanimates an army of unknown shinobi led by Danzo’s former bodyguard Torune to retrieve the ones he lost to the Allied Forces. But aside from Torune, the reanimated shinobi are all weak and are quickly sealed away.
