One-Tail

One-Tail's History

Shukaku and the tailed beasts first came into being in the waning days of Hagoromo Ōtsutsuki, who used his Creation of All Things Technique to divide the Ten-Tails' chakra into nine separate bodies and giving each a name. Some time after being created, the Sage explained to the young tailed beasts that a link existed between them despite their separation. He also foretold of a day when they would be brought together again - though not as they were - and that at that time someone would emerge to show them what true power is. In the anime, before his death, Hagoromo sent Shukaku to live in a temple built for the purpose of protecting it in a desert region that would later become part of the Land of Wind.

Long before the First Shinobi World War, Shukaku was captured by disciples of a temple and kept in Sunagakure, to which the First Kazekage, who was invited along with other first Kage by Hashirama Senju into the first Five Kage Summit, attempted to use his possession of the tanuki as leverage to gain wealth for his nation, as opposed to gaining another tailed beast.

Shukaku's first jinchūriki was a Suna priest named Bunpuku, who was locked away in a dungeon with the giant tea kettle, and was kept under constant guard. Over time, the citizens of Sunagakure came to believe that Shukaku itself was a living ghost (生霊, ikiryō) of a corrupted priest sealed inside a tea kettle. Despite the animosity the village showed for Shukaku and its host, the elderly priest held no ill-will towards the tanuki nor the villagers, viewing it as an equal and was content as long as Shukaku hadn't forgotten his name. Shukaku eventually came to appreciate Bunpuku and would later remember the words he imparted to it: that someday someone would appear in the world to teach it about the heart and acceptance. Shukaku had another jinchūriki who inspired the Third Kazekage to create his Iron Sand fighting style. Shukaku was eventually removed from their bodies, resulting in their respective deaths.

When Karura became pregnant with Gaara, her husband, the Fourth Kazekage, had Chiyo seal Shukaku into Gaara while he was still in the womb because, out of his three children, Gaara was the only one compatible with the tailed beast. Before Karura died after giving birth, she passionately told her son that she would protect him, and, according to her husband, her love seeped into the sand and was noted to form his automatic defence. However, Gaara couldn't properly control Shukaku's powers, killing or injuring several of Suna's shinobi and citizens by accident. Shukaku would even cite its hatred toward humans, warning Gaara not to sleep too long if he didn't want to give Shukaku an opening. Deemed a failure, the Fourth Kazekage chose to test his son one last time, ordering Yashamaru to assassinate him and also tell him that his mother never loved him, and that she was used as a human sacrifice for the sealing process. Gaara failed the test, fully releasing the rampaging Shukaku, to which the Fourth eventually used his Gold Dust to subdue the tanuki.
