Naruto reproaches Sasuke for attempting to kill Sakura. Then Sasuke reveals that he killed Danzo with his own hands. He goes on to declare his intent to purify the Uchiha clan’s name by annihilating the Hidden Leaf.

As Naruto and Sasuke clash, their Rasengan and Chidori explode, sending them both flying. When Zetsu and Madara appear to aid Sasuke, they decide to retreat to the Akastuki headquarters. Before they leave, however, Naruto has one last thing to say to Sasuke; something that will have an impact on both of their lives.

Naruto returns to the Leaf Village, and his teammates demand to know why he didn't finish Sasuke off when the latter was in such a weak state. Naruto tells them that when the time is right, he will deal with Sasuke personally. Meanwhile, a supposedly deceased member of Akastuki has infiltrated the Hidden Cloud Village.

The formation of the Allied Shinobi Forces is ratified by the Feudal Lords of the Five Great Nations. Each Kage returns to their village to prepare for the coming war.

Naruto gathers his friends and tells them that he will defeat Sasuke alone. Meanwhile, the Elders of the Leaf officially nominate Kakashi to become the next Hokage.

In Mount Myoboku, Gerotora, Fukasaku, and the Great Lord Elder are debating whether to give Naruto the key to the Tetragram Seal left behind by Jiraiya, an act that could unleash the Nine Tails.

At Mount Myoboku, Naruto prepares to store Gerotora within himself, but hesitates as it also holds the potential risk of unleashing the Nine Tails on the world.

Tsunade talks to a council and informs about the Fourth Shinobi World War and warns others not to underestimate Akatsuki. Whereas in Land of Lightning a council is held about war, as Kisame spies on them. B paying no attention was bought in writing raps in his rhyme book. Later, Shizune informs Tsunade about Naruto's disappearance for which she ordered some shinobi to search for him. Naruto returns to Ramen Ichiraku. Two Konoha shinobi ask for his autograph, but he doesn't know how to respond. Three days later the Kage meet again to discuss how they should start pooling their resources. As the first matter of business, Naruto and Killer B are to be given constant protection. Tsunade objects since they would both be invaluable in the war with Akatsuki, but is forced to agree. Tsunade meets with A alone and asks him for a favour to let B teach Naruto how to control Nine-Tails. A says that the place where he is sending B and Naruto isn't just a hideout but a training ground. Tsunade returns to the village and informs Naruto that he's going on an S-rank misson to an island located in the Land of Lightning.

After a long voyage at sea, Naruto’s ship finally arrives at the island of its destination. Before everyone can rejoice, a giant squid attacks the ship. Fortunately, the crew is saved by Killer Bee, the Eight Tails’ jinchuriki host.

Motoi confesses to Naruto and Yamato that he attempted to kill Bee during their childhood because of his father's death due to the sealing of the Eight Tails 30 years ago.

With Killer Bee as his new master, Naruto begins his training to control the power of a Tailed Beast. In order to do so, one must fight the Tailed Beast head on and absorb its chakra, converting it into one’s own power.

Inside his mind, Naruto continues his battle against Nine Tails to take control of its immense power.

Sixteen years ago, Fourth Hokage Minato Namikaze and his wife Kushina are expecting their first child, much to the delight of the young couple.

Minato is forced to use his Flying Raijin jutsu and leave his wife Kushina behind to save their newborn son, Naruto, from a masked assailant.

The Nine Tails, having been released from Madara's control, continues to wreck havoc in the city. The Third Hokage summons the Monkey King Enma and drives the Nine Tails away from the city. Minato then returns to the city and with the help of the toad Gamabunta is able to restrain the Nine Tails long enough for him to teleport it along with his family to the outskirts of the village. Kushina binds the Nine Tails and as Minato prepares to do the Reaper Death Seal to seal away half of the Nine Tails Chakra and seal the rest inside Naruto using the Eight Trigrams Seal. He also seals a bit of Kushina's chakra to help Naruto tame the Nine Tails. All of this is witnessed by the Third Hokage and a few other ninja.

Guy arrives at the Waterfall of Truth to help Naruto with his training. Instead he encounters Kisame, who has infiltrated the island to locate Naruto and Killer Bee.

The after-effects of Guy's Daytime Tiger are felt throughout the island. Kisame is defeated, and Guy explains his technique. Yamato restrains him so Aoba can gather intel. When he's about to learn Tobi's identity, Kisame forces himself awake by biting off his own tongue. Kisame breaks free of his restraints and creates a water dome around himself. He recalls Itachi's words about learning what kind of person one is when they die. Knowing he's too weak to resist, and to prevent his enemies from gathering intel, Kisame summons sharks and allows himself to be eaten. The others are impressed by Kisame's resolution. When they open the scroll Kisame intended to deliver, it turns out to be a trap, leaving them stuck inside water prisons, while a summoned shark takes the scroll with the intel away.

Tobi heads to Hidden Rain Village to retrieve Nagato's Rinnegan. Konan, now a former member of Akatsuki, recollects her past until Tobi arrives. Tobi asks Konan where is Nagato's Rinnegan and Konan replies that it is not located in the village. Their battle started and Tobi tells Konan that he encouraged Yahiko to form Akatsuki and he gave the Rinnegan to Nagato. Konan transforms into thousands of pieces of paper to self-destruct against Tobi, yet it fails and both survives. Konan unleashes a powerful paper technique that looks like a sea of paper beneath their feet.

Konan encloses Tobi in an chasm with a large amount of explosive tags that detonates in a wide area. Tobi manages to survive with his Izanagi techique, sacrificing one eye, and pierces Konan behind. Tobi explains his technique to Konan. Konan refuses to give up and continues to fight Tobi. Tobi manages to subdue her and places Konan inside a genjutsu to force her to reveal the location of the Rinnegan. Tobi travels to the location and retrieves Nagato's corpse and then takes his leave. A bloodied piece of paper is blown of Konan's body by the wind and travels to her childhood hideout. As it travels, more of the Ame Orphans past with Jiraiya is revealed, as well as some of their time as the original Akatsuki. Meanwhile, Tobi, with a new outfit, is told by Zetsu that they have received intel on the Nine-Tails wherabouts from Kisame. He declares that it's time to capture the Nine-Tails.

Zetsu reports on new intel from Kisame and Madara learns about Naruto hideout. Tsunade, Gaara, Lord Raikage, and others must figure out how to get Naruto out of the secret island of Land of Lighting and all without telling him about the war. New mission is introduced.

Kabuto and a reanimated Deidara attempt to grab hold of the jinchuriki, but are stopped by the Tsuchikage, who has come to protect Naruto.
