Yagura Karatachi

was the jinchūriki of the Three-Tailed Giant Turtle and the of Kirigakure. When the Three-Tails was captured by Akatsuki, it had no host and roamed out in the wild. The reason why the Three-Tails was removed from Yagura is unknown.

History
During his time as Mizukage, until the massacre of Academy Students by a young Zabuza Momochi, the village was known as the, due mostly because of the barbaric ritual where Academy students kill one another for graduation. It is likely that Yagura was the Mizukage whom Zabuza tried to assassinate.

Despite the terror of his reign, Yagura appeared to be kind. Apparently the people of Kirigakure feared that Yagura was being manipulated, a fear which was confirmed by Ao, who saw through an unnamed genjutsu with his Byakugan.

Eventually, the Three-Tails was removed from Yagura for unknown reasons, and the beast was allowed to roam free. With that, Yagura's life and reign came to an end.

Abilities
Yagura was one of the few jinchūriki that were able to fully control their tailed beast. He wielded what seems to be a large staff, with two hooks on each end, one larger than the other, along with a flower on the larger end; not much else is known about his abilities.
