Chiriku

(chi meaning "earth", and riku meaning "land") was one of the Twelve Guardian Ninja, who once was hired to protect the Fire Country's Daimyou.

Background
He was once part of the Twelve Guardian Ninja. When six of the members tried a coup d'etat he alongside Asuma Sarutobi, Kitane, Nauma, Tou'u, and Seito fought against them. He alongside Asuma and Kazuma was the only survivors of the fight.

When the group disbanded he became head monk at the Fire Temple, an elite monastery that is home to monks with special abilities. During his time with the Twelve Guardian Ninja, some underground organisation put a 30 Million Ryo bounty on his head.

Hidan and Kakuzu Arc
He was later killed by Hidan and taken by Kakuzu, the bounty hunter of Akatsuki, to get the reward.
