Jinchūriki

The are humans that have tailed beasts sealed within them. They exhibit extraordinary powers due to the immense chakra reserves they possess.

History
A millennium ago, the world was terrorised by a rampaging, colossal monster known as the Ten-Tails. Eventually, through the combined efforts of the twin brothers, Hagoromo and Hamura Ōtsutsuki, the Ten-Tails was defeated and sealed within Hagoromo, becoming its jinchūriki. Throughout his travels, Hagoromo used the Ten-Tails' power to perform many great deeds and promote peace during his lifetime, causing him to be revered as the "Sage of Six Paths". Towards the end of his life, Hagoromo, knowing the Ten-Tails would be unleashed on the world again when he died, split its chakra into nine living entities called the tailed beasts.

Although humanity would for centuries exploit the tailed beasts as sources of power, it would not be until after the establishment of the hidden villages that the practice of creating jinchūriki resumed. The new hidden villages, each with their own tailed beasts, started sealing the beasts into selected villagers: in Konohagakure this was done to protect the village from its beast, the Nine-Tails; in Sunagakure, the abilities that manifested in their jinchūriki were studied so that non-jinchūriki could replicate them; more often than not, though, the jinchūriki were meant to be nothing more than military potential, with little regard for the jinchūriki or even the tailed beast.

Because of the difficulties involved when learning to control a tailed beast and the history the tailed beast itself may have with a village, jinchūriki are often hated and ostracised by their fellow villagers, treated as no different than the beast they contain. Members of Akatsuki report that villages are often glad to be rid of their jinchūriki. However, because a jinchūriki is so valuable an asset, it is not in the village's interest to let them be captured or turn into missing-nin. To strengthen the jinchūriki's bond with the village, it is tradition for them to be related to their village's Kage: for example, Killer B is the brother of the Fourth Raikage and Gaara is the son of the Fourth Kazekage.

While many jinchūriki do indeed experience hardship in their early lives, either being mistreated by the majority of the village or dying in their failed attempts to control their tailed beasts, some are able to earn respect and recognition both within their village and in the wider world: Gaara and Yagura becomes their villages' Kage, while Killer B, Yugito Nii, and Naruto Uzumaki become regarded as heroes and icons of their villages, with Naruto also becoming a Kage eventually.

Sealing
Jinchūriki typically have their tailed beasts sealed into them early in their lives - often shortly after birth - so that they can can grow up acclimating to their beast. Which seal is used differs from village to village, with Konoha using the Eight Trigrams Sealing Style and Kumo using the Iron Armour Seal. In order for a jinchūriki to be successful in the long term, it is important for the jinchūriki to have special compatibility or simply unique chakra that can improve their chances. If a jinchūriki has been one for a long time, their chakra will naturally adapt to their tailed beast for better compatibility. In the case of the Ten-Tails, it is also necessary that its jinchūriki have a living body.

There are several ways in which a tailed beast can be removed from its jinchūriki. If the jinchūriki loses control of the beast or if the seal is simply allowed to weaken enough, the beast will be released. For female jinchūriki, seals are at their weakest during childbirth, due to the nurturing of the child in the womb taking precedence over the reinforcement of the seal. As such, another ninja is required to keep the seal intact during childbirth and restore it to full power afterwards. Akatsuki uses the Sealing Technique: Phantom Dragons Nine Consuming Seals to extract the tailed beasts and seal them within the Demonic Statue of the Outer Path for future use.

Typically, loss of a tailed beast will cause immediate death for a jinchūriki. Uzumaki have been shown to survive the initial removal of their tailed beast, but they are left severely weakened and need immediate medical attention if they are to live. If a jinchūriki is able to hold on to or receive some of their beast's chakra, that will also enable them to survive. The Ten-Tails' jinchūriki can survive its removal so long as the Demonic Statue remains within them, though they will be completely paralysed for a time. Reincarnated jinchūriki can survive their beast's removal since they are already dead, but they may lose consciousness in the process.

Abilities


A jinchūriki has access to their tailed beast's massive chakra reserves. Most jinchūriki learn how to access this chakra on their own and take it by force, but they can also form a symbiosis with their tailed beast and take only what chakra is offered to them. A tailed beast may even give chakra to its jinchūriki without them knowing it, either to try and exert control over the jinchūriki, or simply to protect the jinchūriki and, by extension, itself.

In addition to the chakra reserves, jinchūriki gain abilities unique to the respective beast. As the jinchūriki transform themselves into the likeness of their tailed beasts, it further increases the power of their abilities. If they are able to survive their beast's removal, they will still have access to those abilities.

Control
Jinchūriki that have tamed their tailed beast can summon it outside of their bodies while retaining enough of their tailed beast's chakra to avoid suffering the effects of death or critical condition that comes with a tailed beast extraction to fight on their behalf. Afterwards, the tailed beast has to either be resealed or is de-summoned back into the jinchūriki.

Physiology
The incredible chakra granted to the jinchūriki by their Tailed Beasts can, whether controlled or not, manifest in the hosts through physical mutations, and at times, seemingly alter ones genetics. Common examples of this are the Tailed Beast Mode and variants of its partial transformations, although it is also exhibited through the jinchūriki's rapid regenerative abilities and ability to survive what would generally be mortal wounds, such as being impaled through the chest, severe burns, dismemberment, and even disfiguration caused by the Tailed Beast transformations. The jinchūriki, with enough mastery and control of their power, can freely use the properties of the Tailed Beasts, such as Gaara's ability to control Shukaka's sealing formula and Naruto becoming an energized chakra avatar of himself and Kurama in Nine-Tails Chakra Mode.

In the anime adaption, it is shown that Kaguya Ōtsutsuki would sprout horns and activate both her Byakugan and Rinne Sharingan upon eating from the God Tree – later merging with the tree to ultimately become the Ten-Tails during her battle against her sons. Succeeding jinchūriki of the Ten-Tails (with an exception for Hagaromo Ōtsutsuki) would later inherit her colorless hair and trademark pale complexion, as well as the six tomoe markings present on her clothing.

The offspring of a jinchūriki, particularly those conceived from female hosts, are shown to inherit in-born mutations corresponding with the Tailed Beast. Kaguya Ōtsutsuki's half-human twin sons, Hagaromo and Hamura, were both born with sets of horns that were comparably smaller than the ones first manifested by their mother upon eating the God Tree's fruit. Naruto Uzumaki was directly influenced by the Nine-Tails' chakra throughout his mother’s pregnancy due to the sealing mark, and by proxy, was born with thinly slitted eyes and three fox-like whisker markings on his cheeks. Naruto's own children, Boruto and Himawari, also inherited their father's whisker marks, except fewer in number.

Similarly to how the Tailed Beasts provide enormous reserves of chakra to their host bodies, children of jinchūriki typically boast extraordinarily natural talents in ninjutsu, and whether their skills are initially evident or not, they are hailed as elite geniuses throughout their life-times. Hagaromo & Hamura Ōtsutsuki, Indra & Ashura Ōtsutsuki, Naruto Uzumaki, Boruto & Himawari Uzumaki, and Team Shinki are all notable examples of this.

Although Hashirama Senju was neither a host for Tailed Beasts nor directly the offspring of one, both he (and Ashura Ōtsutsuki after inheriting the Hagaromo’s "body" in the anime) were capable of producing the unique Wood Release chakra nature: a power only the Ten-Tails itself exhibited. Hashirama’s connection to the Ten-Tails through his Ōtsutsuki ancestry, its original hosts, as well as his spiritual predecessor Ashura, through unknown means, correspond with his ability to use the Tailed Beast-exclusive Kekkai Genkai.
