Chiriku (地陸) was one of the Twelve Guardian Ninja, who once was hired to protect the Land of Fire's Daimyo.
He was once part of the Twelve Guardian Ninja, at which time he developed a strong friendship with Asuma Sarutobi. When six of the members tried a coup d'etat he alongside fought against them along with the other five members of their group. Chiriku, Asuma, and Kazuma were the only survivors of the fight.
