Jinchūriki

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

History
Long before the founding of the hidden villages, the world was terrorised by a monster known as the Ten-Tails. Its rampages throughout the lands were stopped by the combined efforts of Hamura and Hagoromo Ōtsutsuki, who sealed the Ten-Tails within Hagoromo. As history's first jinchūriki, Hagoromo used the Ten-Tails' power to perform many great deeds during his lifetime, causing him to be revered as the "Sage of the 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 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 that 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, 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 regraded as heroes and icons of their villages.

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. 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 technique to extract and seal the tailed beasts 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.
