Fourth Shinobi World War: Countdown

The Fourth Shinobi World War arc spans from chapters 488 to the current manga. All the Five Great Shinobi Countries have formed a ninja alliance and prepare for the Fourth Great Shinobi World War, and also the final battle against Akatsuki.

Preparing for the War
Returning to Kiba, Lee, Akamaru and Sai, Sakura and Naruto all go back to the village along with Kakashi and a weakened Karin. Upon return, the others tell Naruto that they want to fight Sasuke too and he can't fight him alone. Naruto disagrees and says he is the only one who is able to fight Sasuke and the only one that will, the others question him on what happened when he confronted Sasuke. Naruto says he will tell them when the time is right, and walks off to Ichiraku Ramen Bar. With Danzō dead, the Village leaders have to decide on a new 6th Hokage and vote Kakashi for the position saying that they think the Sand Village will agree as well. The Fire Daimyo says "Kakashi Hatake, I now appoint you as..." but is cut off by a ninja running into the room and telling the Fire Daimyo that he has urgent news. Shizune then breaks out in tears as she sees Tsunade has survived and hugs her, thus removing the need for a 6th Hokage.

At the same time, in their hideout, Sasuke is shown regaining consciousness again after the operation in which Itachi's eyes were implanted in him. Sasuke states he can feel Itachi's power flowing into him.

Meanwhile, Tsunade is eating a lot to rebuild her chakra reserves. She is greeted by Kakashi, who is relieved that she is alright, as it would have meant him becoming Hokage, and he feels he isn't cut out for it. Tsunade orders a meeting to make preparations for the coming war. Elsewhere, Ibiki interogates Karin on information about Sasuke and Kabuto.

The Great Toad Sage has seen a vision of Naruto, and would like to see him before he decides whether or not he should receive the key to his seal. Naruto is enjoying some ramen, when Sakura informs him of Tsunade's recovery; this leads to his next meal being declared "on the house". As he is about to eat, he is reverse summoned to Myōbokuzan, to receive the premonition; the Sage sees "octopus tentacles" and "a young man with powerful eyes". Naruto listens to what he has to say, and accepts what ever lies ahead.

Anko and her team have located a number of bodies, evidently victims of Kabuto. The fact that he just left them there and made no attempt to hide them leads the team to suspect a trap. Meanwhile, Kabuto has located Madara, and after a brief showcase of his new abilities, resurrecting Itachi, Deidara, Kakuzu, Sasori and Nagato and offers an alliance with Madara. Kabuto asks for Sasuke to test out his ninjutsu. Madara asks if he refuses and Kabuto summons another casket with an unseen body that shocks Madara. Madara then accepts the offer but Kabuto can not been anywhere near Sasuke until the end of the war. Near by, Anko and her team discover Kabuto has joined with Madara and she wonders what his motive is and reports the news to Konoha.

Back at Myōbokuzan, Naruto signs the contract to the key, knowing he is ready to control the Nine-Tailed Demon Fox and Gerotora stores himself inside Naruto. Naruto asks the Great Toad Sage about where to find the octopus but only tells him he sees an island paradise. Fukasaku sends Naruto back to Ichiraku where two Konoha ninja there ask for his autograph. At Kumogakure, A calls a short meeting with the other Kage.

Confinement


Three days later, the Kage discuss about the enemy's power and confining the Jinchūriki. Tsunade is outraged by confining Naruto and Bee saying they would help greatly in the war though Gaara and Onoki calm her down telling her it was decided. A says Naruto and Bee will be confined on a island in Kumogakure that him and Bee train at. As Naruto, Yamato and other Kohoha and Kumo ninja arrive at the island, a giant squid (who Naruto thinks is the octopus the Great Toad Sage spoke of) appears and grabs Naruto until he is saved by Bee in his full eight-tailed transformation. One Kumo ninja, Motoi greets them and guides them through the island. While guiding them through the island, they are confronted by King, a large gorilla that Bee has tamed. Motoi tells Naruto not only can he control the beasts on the island, but he can also control the Eight-Tailed Giant Ox, learning Bee is also a jinchūriki.

Nine-Tails Control Training
Later, Naruto asks Bee if he can help him control the Nine-Tails and Bee refuses. Naruto tries a rap but messes it up by unintentionally insulting Bee and tries to fix it with the Harem Technique though Bee slams the door on Naruto. Naruto goes to Motoi to ask him how Bee trained to control the Eight-Tails and shows him to the "Waterfall of Truth", the first step of how Bee learned to control his tailed beast. Motoi tells him to sit in front of the waterfall and close his eyes when an evil version of Naruto appears from the waterfall.
