Paradise Life on a Boat

The Adventures at Sea Arc is the fifth filler arc from Part II of the series, and spans from episodes 223 to the current of the Naruto: Shippūden anime. This arc shows Naruto and his team on their journey to the Land of Lightning by sea, to confine him from Akatsuki during the Fourth Shinobi World War.

The Giant Marlin
A team consisting of Yamato, Aoba Yamashiro, 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 One 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.

The 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 Skeleton 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.

Battleship Island
While sailing to the Land of Lightning, Naruto Uzumaki and the others are attacked by pirates who wanted to sink their ship and loot the wreckage.

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.
