Utakata (ウタカタ, Utakata) was a missing-nin from Kirigakure, as well as the minor supporting character of Naruto and the jinchūriki of Saiken, the Six-Tails, which has been captured and sealed by Akatsuki, causing his death when the beast was extracted. However, upon his reincarnation, Saiken was resealed within Utakata.
