Isobu (磯撫, Isob'u), more commonly known as the Three-Tails (三尾, Sanbi), is a tailed beast that was formerly sealed in Yagura of Kirigakure, after being sealed in Rin Nohara as part of Kirigakure's plan to attack Konohagakure. It has been captured by Deidara and Tobi, then sealed by Akatsuki. It was later resealed into a reincarnated Yagura during the Fourth Shinobi World War.[2]


[1]The young tailed beasts with the Sage of the Six Paths.Isobu first came into being in the waning days of theSage of the Six Paths, who used his Creation of All Things ability to separate the Ten-Tails' chakra from its body and divide it into nine separate constructs in order to ensure that it would never resurface after his death.[3][4] Some time after being created, the Sage sat down with all the young tailed beasts and told them that they would always be together even when separated, and that one day they would become one entity again with different names as well as forms than they did then when the time came for them to understand what true power is.[5]

At some point in the past, Isobu, who was in the possession of Kirigakure, was sealed within a kidnapped Rin Nohara of Konohagakure. They plotted for Rin to be taken back to her village, where they would release the tailed beast to wreak havoc in Konoha. This failed however, as Rin who was fully aware of their schemes opted to kill herself before their objectives could come to fruition.[6] Eventually, Isobu was revived and sealed within its next jinchūriki — Yagura, the Fourth Mizukage.[7] However when Akatsuki went after it, the turtle was in the wild; the story behind how it came to be like this is still unknown.

In the anime, Tsunade states that Isobu's disappearance happened after a great war.[8]


Isobu speaks in a shy manner, referring to itself as 'boku' (ボク) which is usually used by young boys.


Isobu primarily resembles a large turtle, but with a crab-like shell, and three shrimp-like tails. Under its shell, it has red, muscle-like tissue. It has a pair of human-like arms and hands, but no hind-legs. Its lower jaw is rather big and has teeth-like horns, together with its big forehead, which also has horns, it somewhat resembles a mouth with big teeth, making it look like the rest of the face is inside the mouth. Its eyes are dark and have red pupils. In the anime, the eyes are red with green pupils. Its right eye is constantly closed, indicating some sort of injury, and because of this, it is particularly vulnerable to attacks directed at its right eye. During the last remaining days of the Sage of the Six Paths, Isobu was much smaller than it currently is but was still many times larger than the Sage.[5]


[2]Isobu using the Tailed Beast Ball.See also: Yagura's Jinchūriki FormsAs a tailed beast, Isobu possesses an enormous amount of chakra and can perform the Tailed Beast Ball. It also has the ability to create coral, and swim at very high speeds. Tobi suggested that Kisame would have been a better choice for capturing the beast, given its affinity for water. Isobu has also been shown to be able to roll into a ball and attack its opponents, making full use of its shell and its many protrusions in a manner similar to the Akimichi clan's Spiked Human Bullet Tank. Its tough skin and shell also provides additional defence for the beast, allowing it to withstand nearly all forms of attack. In the anime, it was revealed that its only known physical weakness it possessed was its eye, as hard as its skin and armoured shell are, it cannot harden its eyes and so seems to keep one closed at all times. [3]Isobu rolled into a ball.In the anime, its abilities were greatly elaborated upon, many of which dealt with its size: it could roar to repel attacks; it could produce a large tidal wave that spread away from it in all directions; it could strike with any of its three spiked tails to break through most defences. Its skin was resistant to attack in a similar fashion. With these abilities, it overwhelmed Guren's Crystal Release several times over the course of their battle. [4]Isobu firing chakra-infused water balls.Of the beast's more specialised abilities, it could produce a hallucinogenic mist that exploited the victim's insecurities and forced the victim to face them. It could also shoot powerful chakra infused water balls. When it ate something, thousands of miniature versions of itself would attack what it had eaten within its stomach, presumably to speed up the digestion process. In addition to its anime appearance, the beast was shown capable of materialising an entrance to a separate dimension in which it could hide its presence, until it was ready to return.  ==Part II==

Three-Tails ArcEdit

Main article: Three-Tails Arc [5]The entrance to the dimension where Isobu came from.In the anime, Orochimaru instructed Kabuto Yakushi and Team Guren to take a young boy named Yūkimaru to a lake. After they arrived, Kabuto forced Yūkimaru to release all of his chakra, which caused Isobu to begin to surface from the lake. With Guren's help, the beast was completely revealed, and they attempted to capture it. Their attempts proved insufficient, however, and the beast created a large tidal wave to wash its attackers away.

The tidal wave gained the attention of a nearby group of Konohagakure ninja, who tried to use Four-Corner Sealing Barrier to permanently trap the beast in its own dimension. Just as the sealing began to work, the Konoha ninja were interrupted by Guren, which prompted the beast to attack them all. Yūkimaru was able to calm the beast down temporarily, but, after he became tired, Isobu turned its attention to him. Guren and Naruto Uzumaki came to his defence, but were swallowed in the process. With the help of their allies on the outside, they were able to escape, and the Konoha ninja tried once more to seal the beast.

Just when the sealing was almost complete, Yūkimaru, angered by the apparent death of Guren, empowered the beast to break free of its restraints. Isobu went on a rampage, attacking everyone nearby and crushing NurariKigiri, and Kihō. Its attempts to attack Yūkimaru, however, had no effect. It was only through the use of the Wind Release: Toad Oil Flame Bullet that the beast was driven away. The sealing attempt was left to ANBU members, and the remaining Konoha ninja returned home. Deidara and Tobi of Akatsuki soon found these ANBU members and disposed of them.

The beast's capture took place much earlier in the manga (at the start of the Hidan and Kakuzu Arc), but played out in much the same way as in the anime. Tobi and Deidara confronted the beast, to which it responded by beginning to chase Tobi. With Isobu distracted, Deidara moulded an explosive clay fish in an attempt to capture it. It was unclear if this marked the end of the battle, as the remainder of the battle went unseen. As the two towed Isobu to the Akatsuki's lair after the battle, Tobi gloated at bringing Isobu down with his special technique, but Deidara thought otherwise. It was later sealed in the sealing statue.

Shinobi World War ArcEdit

[6]The remaining jinchūriki transform into their tailed beasts.After Son Gokū is resealed into the Demonic Statue of the Outer Path, Tobi, who is intent on going all-out from this point on, forces Yagura to fully transform into Isobu.[9]

Preparing to attack the shinobi, Isobu along with the other four beasts createTailed Beast Balls. These attacks however, are deflected by Naruto and they arerebuffed by a now fully-transformed Naruto. Wasting no time in their attacks, Isobu evades Kurama's attack and then, rolling into a ball, attempts to attack the beast while Saiken had incapacitated it. It is however stopped by Gyūki. Freeing itself from the beast's grasp, it and the other opposing beasts prepare a collaborative Tailed Beast Ball which is met by one from Naruto and Kurama. [7]Isobu, alongside the other jinchūriki and tailed beasts, encounters Naruto.As Naruto enters a deeper plain of the tailed beasts' consciousness, Isobu introduces itself to the young man. Later, as the beast is freed from the chakra receiver it affirms Kurama's belief that Naruto was the person the Sage of the Six Paths had spoken about so long ago before being resealed into the Demonic Statue of the Outer Path.  ==Video Games== Although Isobu itself is not playable, Yagura takes on its form as his awakening in Naruto Shippūden: Ultimate Ninja Storm 3. Isobu also appears as a boss in Naruto Shippūden: Ninja Destiny 3.
