The arc also expands on the character Aoba Yamashiro who will have a somewhat more prominent role in the upcoming arc. This arc is preceded by the Five Kage Summit Arc and is followed by the Confining the Jinchūriki Arc.
The Young Man and the Sea
A team consisting of Yamato, Aoba, and Might Guy and three other unknown shinobi, set off with Naruto to the Land of Lightning, to confine him in an isolated location from Akatsuki in preparation for the Fourth Shinobi World War. The team travels to a harbour in the Land of Fire to travel by sea. Tsunade ordered them to take the long way so Akatsuki wouldn't attempt to capture Naruto. The boat the team takes is rather small one, so they won't get noticed. Some fellow Konoha ninja warn them about a sea monster that attacks any ship that goes into open water. Guy decides to sail out with Aoba to the water to fight the monster. Suddenly, the monster attacks Guy and Aoba, and they learn that it is a Giant Marlin summon from the Third Shinobi World War, roaming around the waters of the Land of Fire. As the marlin swims towards Guy, a fisherman named Yūsuke, tries to capture it. The fish destroys Yūsuke's boat and the fisherman is saved by Naruto. Holding Yūsuke prevents Naruto from performing any techniques and is left open. Yamato shields Naruto and Aoba distracts the marlin with the Scattering Thousand Crows Technique while they all escape.
At Yūsuke's hut, the Konoha ninja try to figure out why the marlin did not return home after the war. Yūsuke tells them to not interfere as he wants to capture the fish himself, to avenge his father who died trying to capture it. As the team is about to depart, Naruto wants to help Yūsuke avenge his father to which everyone agrees. The next day, Yūsuke comes out to see a new boat and fishing rod made by Yamato. The team sails out with Yūsuke to search for the marlin. The marlin appears and Guy opens the second of his Eight Gates to keep up with the fish's speed. Yūsuke uses a large fishing lure resembling Naruto to catch the marlin. The fish eventually gets exhausted from pulling on the lure and Yūsuke finally captures the marlin. Afterwards, Naruto notices a fūma shuriken on the marlin's forehead and pulls it out. The marlin returns home shortly after and the Konoha sail on a new boat, waving goodbye to Yūsuke.
The Ninja of Benisu
While on the way to the Land of Lightning, Naruto and his bodyguards stop off at a nearby island, due to all his bodyguards becoming seasick, Guy in particular. While there, they see Sakura, Ino and Chōji picking up medicinal herbs on the orders of Tsunade and Naruto decides to help them, although he does not fare well, from eating poisonous herbs to being paralysed on a bridge. As Chōji spots one of the medicinal herbs, some ninja from the Benisu Island appear and make the Konoha ninja waste their time, while collecting the exact same herbs. However, they have a change of heart and give Sakura, Ino and Chōji all the herbs they picked up, as Naruto saved them from a monster protecting the Elixir Mud. With Guy feeling better, they head off towards the Land of Lightning and Tsunade's team back to Konoha happily, unaware that the Benisu ninja just gave them the herbs, so they could collect the debt owed after the war.
The Cursed Ghost Ship
As they continue their voyage towards the Land of Lightning, Naruto, Aoba, Guy and Yamato sail through a thick fog. Yamato tells Aoba and Naruto about the "Ghost Ship" to pass the time. Suddenly, they met another ship, very much same to Yamato's description of the said ship. They come to the ship to investigate, and meet Hishaku, who is revealed to be a "soul" who cannot rest because of the guilt when the ship was attacked by the Giant Corpse Crab. Naruto and the others help him revenge the said crab, and later was revealed all his co-sailors and the captain cannot also rest. After defeating it, Naruto continued sailing, as well the ship set free.
Thanks to some fast thinking on Yamato's part and the early warning by one of the sensor-type shinobi however, the ship is saved and they dock in an underground cavern. There they find a burial ground and a journal telling of the plight of the native islanders at the hand of the wicked Gataro and his men. Hearing this, Naruto vows revenge for the deceased and comes up with an ingenious strategy on how to escape the giant geyser that they were trapped in. Using Naruto's strategy the Konoha shinobi and crew were able to escape the island and put Gataro and his men out of commission.
The Forgotten Island
While on their voyage to the Land of Lightning, a giant bird swoops down and kidnaps Guy. The team pursues the bird and are lead to a volcanic island. Upon arrival, Aoba spots a mysterious girl watching them and decides to pursue her while Yamato and Naruto search for Guy. During their search, Naruto and Yamato encounter many giant creatures, including the bird that kidnapped Guy. They eventually locate the bird's nest where they find Guy, who was actually kidnapped to babysit the bird's chicks. Meanwhile, as Aoba pursues the girl, he discoverers the animals on the island are actually bred to be used by shinobi as summons, as well as a research dedicated to developing the ultimate summon. He continues to follow her, and he is lead inside the volcano and finds a huge monster asleep inside an abandoned research lab. Using a mind reading technique, he discovers the monster was too powerful to be contained and had devoured many of the islands summons, as well as the researchers, before going to sleep.
The bird takes Yamato, Guy and Naruto to the volcano where they then encounter Aoba, and the beast suddenly awakens, going on a rampage. The monster is powerful and uses genjutsu as well as Lightning Release. Naruto has to enter Sage Mode while Yamato protects him as Guy and Aoba fight the beast in order to buy some time. Guy manages to knock the beast into the heart of the volcano, but the monster can also fly. The bird which kidnapped Guy comes down and attacks the monster along with the other summons. The girl, actually the spirit of the girl who the researchers used to restrain the beast until it grew too strong, appears and manages to immobilise the beast, with Naruto finishing it off with Wind Release: Rasenshuriken.
Fight! Rock Lee!
Lee dreamed fighting Tobi, after awaking, he then thinks about his training to the upcoming war, and saw a boat, while Guy remembers their past "visualisation training" with him using the menu in a restaurant they celebrated when Lee mastered Reverse Lotus (although they left it in ruins when Lee was drunk). Guy wants to have it kept secret, he said it so they can remember what happened there (although he really knows what happened). First is training the White Crane Fist, but the birds beat them. Then the Snake Fist, but the quicksand almost killed them. Next is the Eagle Claw Fist, they had to climb on a seemingly-like cliff, but the eagle caught them. The last is then Lee getting near to know it, but Guy thinks of an alibi, but when they trained in a waterfall he then realises, and learned the Seasick Fist, which he then defeated Guy. Naruto then commented that he can't use said fist unless he didn't overcome his seasickness. Lee is later shown training it while riding in a boat.
Eat or Die! Mushrooms from Hell
The group stops for supplies and prepare to enter an area devoid of fish of the sea and wind that takes two weeks to be crossed. In the hold, a mushroom purchased by Naruto begins to multiply and to absorb the chakra of Yamato. After resisting for a long time without food, Naruto and Guy taste the mushrooms and it poisons them and push them to act in a violent manner. Without alternatives, Naruto calls Gamatatsu and asks him to bring him Shima's food, composed of insects. All aboard eat and regain strength, even managing to defeat the bandits who sold them the mushroom when they come to look for valuable cargo.
Revenge of the Shadow Clones
After having braved a storm, four of Naruto's shadow clones rebel against him, taking him hostage, forcing the crew to stop in an island. Naruto's clones were going to kill him, but he wakes up and realises it was all just a dream of one of his clones. So, when the clone was extinguished, his memories was transferred to the real Naruto. Naruto becomes respectful of his clones and releases the technique, giving the clones the rest they craved and deserved.

To help ease his mind, Shikaku sends his son along with Tenten on a mission to Mokuzu Island to replenish supplies. On the island, Shikamaru meets up with Naruto's group. Soon after they set sail, the fog around the area gets thicker and they encounter reef systems, a huge rock and a whirlpools again and again. Shikamaru figures that their ship is sailing through the bay in circles and tells Naruto and the others to sail straight for it and get swallowed up.

The girls are later joined by Shizune and a moderately intoxicated Tsunade. Tsunade attempts to apologise for how she dismissed Hinata earlier but Hinata tells her it was fine as she knew what she had to do. The next day during her training with Neji she tells him that she bore no ill will towards him for her father's decision and that he was the right person to lead them in the war.
While crossing part of their trajectory by land in the Land of Water's territory, Naruto's group comes across an imposter, claiming to be him. He and his partner are acting as criminal and hero duo, claiming to defeat Naruto, who had apparently become famous due to his victory over Pain, in order to build up a reputation for themselves during the upcoming war.

Shino tells them that this was in fact true but he was not worried because he had friends he could depend on. Shino recounts a mission he had while a genin to capture a bandit. The mission was initially unsuccessful, as Suika was able to defeat Shino in close combat taijutsu and at the same time called him weak and mocked him use of insects in battle. It is later revealed that the bandit is a jōnin-level missing-nin from Takigakure and as such they would not have stood a chance against him. His pride hurt greatly however, Shino secludes himself at his house to work alone. Kiba, Akamaru, and Hinata however had other plans. Together the team trained to help Shino improve his taijutsu skills. The next day a messenger pidgeon from Kurenai says that the bandit was in the area, Kiba, Akamaru and Hinata prepare to go ahead leaving Shino, who had said just before that he didn't feel qualified to be on their team, much to Kiba's and Hinata's shock.

Ah, My Hero Lady Tsunade!
After Rock Lee falls into a river during their training, Tenten has a flashback of her youth, while waiting for him to surface. When she was a child, she had dreamed to become a strong kunoichi like her heroine: Tsunade, and thanks to Guy's guidance she initially began her path towards becoming a legendary medical-nin. However she failed during her training trying to heal a fish, and her attempts to sign a contract to summon a creature like Tsunade's famed slugs met no success because of her quarrel with Ningame, Guy's summon. After many failures, Guy notes that she had a talent for fūinjutsu and began honing her unique fighting style. After that she realised that she was a weapons specialist and vowed that instead of becoming just like Tsunade, she would still become a legendary kunoichi.
Sai's Day Off
Given the day off, Sai spends it strolling the village and drawing. He initially encounters three children that he at first finds it difficult to interact with, but later he realises that two of them remind him of the times he had spent with Naruto and Sakura.

The Legendary Ino-Shika-Chō
As Team Asuma considers the impending war, they encounter Kosuke Maruboshi who reminds them of the time that they rescued him while they were still genin. With this, Kosuke retells the tale of the time their fathers saved him during the Invasion of Konoha with their Formation Ino–Shika–Chō. Somewhat rattled by this story, Kosuke reminds them that great shinobi weren't made in a day. As the team contemplates everything, they decide to perfect their own formation, insisting that they'd be fine because they were not alone.
Kiba becomes upset that Naruto, the dead-last in their Academy days, had become such a hero. After being chided by his mother Tsume and partner Shino, he decided to train in order to become stronger. Seeking out Kakashi, the only available jōnin sensei currently, he asks him to help him train. Kakashi however summons his ninken to aid Kiba and Akamaru in their training. After initially giving up after being defeated by the hounds, Akamaru carries Kiba to a tree in the village where he sees that Naruto had broken his record in speed since the time they were children racing for candy. With his determination renewed, he demands a rematch with the hounds and is successfully able to retrieve the scroll. With this Kiba races to the tree and sets a new record, declaring that he'd never give up.
Kakashi, My Eternal Rival!
In Konohagakure, Kakashi while meeting with Tsunade about the impending war, receives an emergency messenger tortoise from Guy with an SOS message, so he heads out to find out what has happened. On board the ship, Guy recalls the time when he and Kakashi first became rivals and their numerous battles since then. Later on in the night, the jōnin meet where Yamato tells them about a rumour of a shinobi capable of not only copying someone's appearance, but also their chakra. Kakashi soon arrives at the ship, and calls for Guy. Unaware that he sent an SOS message, Guy comes to the conclusion that the one before him could be one of those imposters that Yamato spoke of. With this notion Guy proceeds to attack Kakashi and later Aoba and Yamato when they side with Kakashi. After giving Guy irrefutable proof that he was who he said he was by telling him something from their youth, Kakashi returns to Konoha upon learning that the SOS tortoise was sent by accident.
While on his way to meet messengers from Iwagakure, Chōjūrō decides to go on ahead by himself, due to the slow progress in travelling. Naruto and his group stop in an island for restocking before going straight to the Land of Lightning. Naruto sets off to eat. Akatsuchi is sent by the Tsuchikage to the same isolated island in the Land of Water to rendezvous with Chōjūrō, and Kurotsuchi tags along. As they await, they're attacked by a group of Kirigakure ninja, led by Ganryū. Battle ensues and Akatsuchi is injured. Naruto and Chōjūrō interfere and stop the battle. Chōjūrō demands Ganryū and his team to withdraw, stating that they are violating the Mizukage's will. The team leaves, and Kurotsuchi argues with Chōjūro to tend Akatsuchi's injuries, who says they need to wait for a medical-nin. Chōjūrō explains those were ninja who oppose the Allied Shinobi Forces, Ganryū being the sole survivor of the Tragedy of Yosuga Pass.
Kurotsuchi heads out to kill Ganryū before he can kill her. Naruto stops Kurotsuchi and Ganryū from killing one another, also telling Ganryū that it will just create a cycle of hatred. Kurotsuchi attempts to slash Ganryū using her sword, but Naruto blocks it with his body. Ganryū agrees to let Naruto fulfil the peace. Chōjūro arrives with other Kiri ninja, telling Ganryū to surrender, which he does. Chōjūro informs him that the Iwa messenger was sent by the Tsuchikage himself, to formally apologise for the Tragedy of Yogusa Pass, and return a personal belonging of one of Ganryū's team-mates who was killed in it. Chōjūro tells the others that Ganryū won't be sentenced for execution. Akatsuchi then tells Kurotsuchi that Kiri will just owe Iwa a favour in the future to come, delighted that the Iwa-Kiri grudge has come to an end. Naruto leaves in a hurry, without introducing himself to the others. Once arriving with Yamato and the others, they await for a new ship to take them to the island in the Land of Lightning.
