Hagoromo Otsutsuki, known to the world at large as the Sage of Six Paths, was a legendary god-like figure who founded Ninshu, which led to the creation of the ninja world. He was the son of Princess Kaguya Otsutsuki and alongside his fraternal twin brother, were the first to be born with the same powerful chakra as their mother. Both he and his brother defeated their mother, who had become the terrifying Ten-Tails, in battle and sealed the powerful beast within him, thus making Hagoromo the first jinchuriki. The Ten-Tails (Jubi) is the embodiment of Kaguya Otsutsuki combined with the God Tree, created to reclaim the chakra inherited by her sons, Hagoromo and Hamura. It is regarded as the progenitor of chakra, and is tied to the legend of the Sage of Six Paths and the birth of shinobi. To end the beast's rampage, the Sage became the Ten-Tails' jinchuriki and later split its chakra into the nine tailed beasts to prevent it from causing further harm. Centuries later, its revival became the objective of Madara and Obito Uchiha, who both sought to become the beast's jinchuriki in order to further their objectives.
