Utakata

was a missing-nin from Kirigakure and the jinchūriki of Saiken, the Six-Tails, which has been captured and sealed by Akatsuki, causing his death when the beast was extracted. However, upon his reincarnation, Saiken was resealed within Utakata.

Background
In the manga, not much was known about Utakata's life, but he was eventually captured by Akatsuki, and had Saiken extracted from his body, killing him. In the anime, Utakata was a powerful shinobi of Kirigakure, who at some point became the jinchūriki of the Six-Tails, Saiken. In his life as a loyal shinobi of the Kiri, he would come to be a student under Harusame. At one point on a mission for Harusame, Utakata had returned with a scroll saying a ninja should carry out and complete his mission swiftly. Frustrated at his student, Harusame angrily said that Utakata's job was to track and locate the scroll; not return it. Harusame would go on to say Utakata's life was precious, mentioning that a ninja should not run away from conflict nor should he involve himself in a battle that was unnecessary. None-the-less, he was grateful for his student to safe and alive.

Some time later, Harusame had attempted to extract Saiken from Utakata, believing the Beast would only cause trouble in his students life, thinking he would be better off without it. Saiken promptly took control of Utakata and killed Harusame, in an effort to prevent itself from being extracted.

According to a member of Kirigakure's ANBU, his master did not, in fact, betray him, but was actually trying to extract Saiken from Utakata. The process didn't go as planned, and instead of removing the tailed beast, Harusame forced Utakata's transformation into Saiken and was killed by it. With only fragmented memories of the incident and the impression of betrayal, Utakata grew disillusioned and sceptical of the relationship between a master and student. He became a wanderer, constantly fighting off people who were after him, particularly the hunter-nin sent from Kirigakure to retrieve him.

One day, he was attacked again. A girl named Hotaru, who happened to be there, assumed the assailants were after her. Utakata managed to fend off his attackers, but was injured in the process. Believing that Utakata had saved her, Hotaru took him to her family's fort for treatment. After he recovered, Hotaru begged him to train her in his ninjutsu, but Utakata adamantly refused, not wanting to become anyone's master.

Personality
Utakata is described as a "charming" individual. In the manga, Akatsuki member Deidara indicated that Utakata was possibly one of the jinchūriki that loathed humanity, due to being neglected and hated by his village, none of whom came to rescue him when he had been captured.

In the anime, where Utakata's character is given a bit more depth, he is usually depicted with a stoic, calm and carefree personality, preferring solitude and is not particularly talkative. Although, if the sensitive subject of student-master relationships is brought up, it typically manages to rouse his annoyance and anger. Hotaru is often on the receiving end of Utakata's ire on this matter as she constantly nags him to become her.

As a result of his complicated relationship with his late master, he utterly despises the word, having remarked that he isn't foolish enough to ever take on the title. In one instance, he said, "I told you not to call me master", to Hotaru as he floated away in a bubble. Hotaru's unyielding attachment and reverence to Utakata flusters him. Despite Utakata's genuine protective feelings for Hotaru, they are hard for him to acknowledge and express due to his nomadic nature and scarring past, though he acts on them if ever Hotaru is in danger. When Hotaru showed Utakata the kinjutsu that had been sealed into her, he visibly displayed anger and outrage that someone would do something like that. He also has a strong sense of honour, often determined to repay his debts to others (like his assuming a guardian role to Hotaru since she and Tonbee saved him). Like Naruto, he has resolved not to rely on his tailed beast for power, aware of the destruction it may cause, an indicator of his maturity. Tonbee also commented that Utakata lacked "greed".

Interestingly, Utakata seemed to have a better relationship with his tailed beast than most, as he could ask it to fully release its power without it forcefully overtaking Utakata's consciousness. Saiken accomplished only the task wished by Utakata and receded into him without any resistance.

Appearance
Utakata is a tall, thin young man with pale golden eyes and brown hair that reaches to his shoulders. His side parting lets a large portion of his bangs cover the left side of his face. He wears a long, light blue kimono adorned with a small emblem of three bubbles on the back, and a pair of black pants underneath, with an orange sash. The kimono hangs loose, exposing his chest. In it, he carries a bamboo jug filled with a soap solution, and a pipe.

In the anime where his background is expanded on, it is shown that during his time in Kirigakure he wore a full body grey suit along with a variant of the village's flak jacket which had very low shoulder guards as well as a zipper and a pouch on the upper right chest. He also wore the village's forehead protector, fingerless gloves, as well as bandages on his forearms.

Abilities
In the anime, he was shown to be agile and nimble in battle, effortlessly dodging and out-manoeuvring all of Naruto's attacks and the assaults from Nangō, Akaboshi, Benten, and Chūshin. He is very observant as he noticed that Akaboshi and his group had a change in their chakra flow. He is also knowledgeable in tracking and herbal remedies.

After his reincarnation and serving as one of Tobi's Six Paths of Pain, Utakata is seen with both the Sharingan and Rinnegan. Combining the perceptual and predictive abilities of the former with the shared field of vision ability of the latter, allowed Utakata to use his attacks in a more precise and coordinated fashion as well as react to enemy attacks more efficiently, both individually and in conjunction and with the other jinchūriki.

Nature Transformation
Utakata fights using ninjutsu from the  of Water Release ninjutsu, performed with a unique kind of bubble-blowing relic.

In the manga Utakata's bubbles have shown an explosive property as seen with his Water Release: Bubbles Technique which themselves can explode on contact with the target or be manipulated to explode all at once by the user. In the anime, this style of ninjutsu is shown to be very versatile. Capable of tactics beyond simply harming opponents, the bubble technique grants Utakata a wide array of offensive and defensive options in combat. With the Explosive Bubble technique — an example of an offensive skill, Utakata emits streams of explosive bubbles that detonate at will. Utakata can also craft dozens of ink-filled bubbles that can immobilise and kill opponents instantly without leaving any trace of them, another offensive variation. Defensively, the bubbles are equally adaptable. Using the Floating Bubble Technique, Utakata can transport and conceal himself simultaneously. He can also create an enormous bubble barrier to protect himself or his allies from attacks like an explosive tag.

Utakata is able to create some bubbles without the use of his bubble blower. In one instance, when Shiranami's technique was pursuing a messenger bird, Utakata popped his floating bubble and conjured another beneath his feet while his bubble blower was occupied with defending the bird.

Jinchūriki Transformations
When Utakata loses his temper, he taps into Saiken's power, enabling him to discharge a burst of Saiken's chakra, similar to that of Naruto's and Killer B's. Before unleashing the tailed beast, Utakata's eyes turn golden. Although he is not one of the four mentioned to be able to fully control their tailed beast, Utakata is able to use the power of each level of Saiken's chakra up to the full Six-Tails form, like Yugito Nii. And despite promising to never use Saiken's power, he was able to stop and absorb a powerful technique, Fury, without any harm by summoning it out of desperation.

When he was reincarnated and the Six-Tails was resealed back into him. Utakata was able to partially transform into Saiken, manifesting one tail. When attacked and immobilised by B's clone, Utakata transformed into his Version 2 form to avoid being sealed away. When he attacked B in his Full-Eight Tails Form, he was shown to able to secrete a corrosive, alkaline substance in this form, which was strong enough to burn the skin of the Eight-Tails. When Tobi forced Utakata to enter his full Six-Tails form, he was able to emit a corrosive gas from its mouths.

Tsuchigumo Kinjutsu Arc
Wishing to repay the debt of having his life saved, Utakata agreed to make sure Hotaru and her grandfather's secret technique would safely be delivered to her clan's village.

Along the way, though, he met Naruto Uzumaki and his team, who had also been assigned to protect Hotaru. Seeing that the Leaf ninja were strong, he felt that he could trust them to guard Hotaru without him, freeing him from his debt. He then left, despite Hotaru's pleas for him to stay, as he noted that he was not foolish enough to want the title of.

Later on, he was seen resting under a tree, eventually falling asleep and having a dream regarding his past with Hotaru at the fort, which turned into a nightmare about his own master's betrayal. Shortly after awaking from this nightmare, Utakata spotted a flicker of a shadow, and decided to investigate.

He came across a group of bandits, none other than Akaboshi's team, who were talking about the kinjutsu. Utakata confronted them and mused about taking the technique for himself, if it was so tantalisingly powerful. He then proceeded to fight them, easily besting them and their technique, until, however, they cornered him with a barrier, which then exploded with Utakata still inside.

When Akaboshi and his group managed to find Hotaru and surround her in the forest, Utakata arrived and saved her from the group, who were shocked to see Utakata still alive and unscathed from their technique. Utakata fled with Hotaru in a bubble to some place safe nearby. Utakata was about to leave Hotaru again, but Hotaru, trying to convince him not to leave her alone, partially took off her shirt, showing him something on her back that shocked him.

All of a sudden, the Kirigakure ANBU found Utakata and wrapped him up with their Water Release: Water Whip technique and began subduing him with their Lightning Release: Electromagnetic Murder. The captain revealed to Hotaru, who he was holding hostage, that Utakata was in their bingo book, and was wanted for killing his master. Naruto and his team arrived and managed to loosen one of the water whips holding Utakata. Both parties began to fight, but the leader of the Kirigakure ANBU appeared, and discussed the situation with Yamato. Due to Hotaru's insistence to be with Utakata, it was agreed that until she was safe, they wouldn't hunt him, but afterwards, they'd resume tracking Utakata down. Tsurugi, the leader, asked Utakata to return to Kirigakure, saying that the village changed, no longer earning the nickname of Village of the Bloody Mist. Utakata refuses, and says that he'll keep doing as he pleases.

After the groups part ways, Hotaru begins hurting from an injury sustained during the earlier altercation. Utakata has Naruto collect medicinal herbs. When Naruto returns, he witnesses what was done to Hotaru's back, where her clan's kinjutsu was put. Utakata voices his absolute disdain for people who selfishly take advantage of people's loyalty, only to treat them as tools.

Utakata is shocked to learned that Hotaru actually requested for the technique to be sealed in her. She explained that she wanted her grandfather's dream to restore their clan's glory to come true. When Tonbee voiced his sorrow that by now the clan had probably lost too much strength to ever return to such a status he suggested they end the potential danger of the kinjutsu by destroying it. Utakata was surprised that Hotaru's grandfather had created a way to safely remove it from Hotaru's body. When Tonbee insisted that no true master would do such horrific things without a way to undo them, Utakata wondered if the same was true for his master, when Hotaru at first insisted, he slaps her, and later apologised. Once Hotaru was convinced to have the forbidden technique removed and destroyed, Utakata resolved to find Tsurugi again to learn some answers about his late master.

When unable to find Tsurugi, he finds a messenger bird with a note for him. While it is from Hotaru saying she found Shiranami, Utakata is still uneasy, feeling something is wrong. He goes to the location Hotaru wrote and finds that Shiranami is actually the leader of the bandits. He also find Akahoshi and his group trapped Naruto in their technique. Utakata then uses his demon chakra to scare the bandits and make them run. Afterwards, he and Naruto track Shiranami back to Hotaru's village, where it is discovered that Shiranami took control of it with his technique. Fortunately, Yamato and the others arrive to hold back the villagers while Utakata and Naruto went on to save Hotaru.

When they arrive, Shiranami was using Hotaru to gather raw chakra needed to use Fury, and binds the two jinchūriki with his Character Bind Technique. Both however used their tailed beasts' chakra to break their bonds and went in for the attack, only for Shiranami, who has control of the kinjutsu, to use Fury. Although injured by Fury, he survived and as Naruto took on Shiranami, Utakata moved to save Hotaru, before the kinjutsu was used a second time. Utakata suppressed the explosion by transforming into his full Six-Tails form. With Shiranami defeated and Hotaru safe, Utakata accepts his role as Hotaru's master, but first leaves to gain permission from ANBU to travel and train with his new student.

On his way, he discovered a bloodied ANBU mask and is confronted by all Six Paths of Pain. Pain attacks Utakata, using the Asura Path to cripple him in a landslide. Before he is captured, he sends a myriad of bubbles to Hotaru, who was unaware of his impending fate. After his capture, Akatsuki extracted Saiken from Utakata, resulting in his death.

Shinobi World War Arc
In preparation for the Fourth Shinobi World War, Utakata was reincarnated by Kabuto Yakushi to fight against the Allied Shinobi Forces, before being mobilised alongside the other deceased jinchūriki.

As dawn broke on the second day, it was revealed that Tobi had turned the reincarnated jinchūriki into his own customised Six Paths of Pain, with each having a Rinnegan and Sharingan in place of their left and right eyes respectively. The jinchūriki also had their respective tailed beasts resealed into them, and each had a chakra receiver implanted in their bodies.

Utakata later travelled together with Tobi, in pursuit of Naruto Uzumaki and Killer B. Encountering their targets, the reincarnated jinchūriki were sent into battle. After the enemy had been repelled by Yagura, Utakata surrounds them with his Water Release: Bubbles Technique, before engulfing the area in a series of explosions with a snap of his fingers. However, when this initial assault failed, he, like the others, unleashed the power of thier respective tailed beast by materialising the first of its tails.

Incapacitated in the wake of the Eight-Tails' devastating attack, after B's recent transformation, Utakata was then restrained by the latter's sealing technique. However, before the technique's completion, he managed to escape by adopting his Version 2 form, only to be caught by the Eight-Tails when he charged at the beast. Utakata then proceeded to free himself from the crushing grasp using his Leech Gap technique, burning the Eight-Tails' hand in the process.

Regrouping with the other reincarnated jinchūriki, after Kakashi Hatake and Might Guy's intervention, Utakata charged towards the pair. Avoiding Kakashi's strike and then repelling both with his tails, Utakata is forcefully transformed into his full Six-Tails form by Tobi. He then proceeds to expel a large amount of corrosive gas from the beast's mouth, forcing the opposition to momentarily retreat, until Guy dissipates the gas. After Son Gokū is resealed into the Demonic Statue of the Outer Path, Tobi, intent on going all-out from this point onwards, forces the remaining jinchūriki to transform into their respective tailed beasts.

Unleashing a Tailed Beast Ball along with the others, the jinchūriki instead resorted to a direct assault when these attacks are deflected by Naruto, only to then be repelled as the latter adopts his Tailed Beast Mode. In the resulting chaos, Utakata manages to immobilise the Nine-Tails' right arm by swallowing it whole, but is ultimately wrenched free after being swung into the Two-Tails. With this, the rival beasts regroup and prepare a collaborative Tailed Beast Ball, launching it towards their opponents only to have it diverted by an opposing one.

Attempting to remove the opposition's chakra receivers in the ensuing blast, Naruto enters the joint consciousness of the tailed beasts, where he meets Utakata along with the other jinchūriki and their respective beasts. During this encounter, he speaks of how they promised Son to remain here in order to tell Naruto something, just before introducing himself alongside his beast, Saiken.

After Saiken was resealed into the Demonic Statue of the Outer Path, Utakata and the other jinchūriki's corpses were collected by B and held in the Eight-Tails' tentacles. With the release of the Impure World Reincarnation, Utakata and the others were enveloped in a light of sorts before their bodies started to deconstruct and his soul returned to the afterlife.

Trivia

 * refers to bubbles on the surface of a liquid. Idiomatically, it also means "transient", "ephemeral".
 * In the manga, Utakata was possibly one of the jinchūriki that were captured before Gaara.
 * He has two musical themes that are remixes of Guren's theme. One is the end part of the theme called The Rain Stops, and the other is called Reflection.
 * In the anime, it was shown that Kirigakure's bingo book states that Utakata is worth a bounty of 5,000,000 ryō.
 * In order to prevent the jinchūriki from becoming a traitor to his or her village, it is tradition for the host to be selected from the family of the village's own Kage. Due to this fact, Utakata could be connected with one of the Mizukage, though regardless of the connections, in the anime it ultimately did not prevent Utakata from defecting.
 * In the anime, Naruto and Utakata had met during the events of the Tsuchigumo Kinjutsu Arc. In the manga, however, the two did not meet until the Fourth Shinobi World War.
 * In Naruto Shippuden: Ultimate Ninja Storm 3, their previous encounter in the anime is taken into account, as when introducing himself, Utakata asks if Naruto remembers him. This only happens in the English version however, as the Japanese audio makes no mention of a prior meeting.
