In Naruto, the Jinchuriki are individuals who have one of the nine Tailed Beasts sealed inside them. Though the Tailed Beasts are locked inside their hosts, they are still separate living beings that maintain their autonomy — for the most part. Jinchuriki rarely choose their fate and are forced to carry this heavy burden, typically for life. Jinchuriki not only have to consistently deal with a powerful entity that wants to control their body, but they are also ostracized from society.
