Chiriku

Chiriku was a bald man with dark eyes, and very thick eyebrows. He wore the standard attire of the ninja monk along with the sash worn by members of the Twelve Guardian Ninja group and went barefoot.

He was once part of the Twelve Guardian Ninja, indicated by the sash on his waist, at which time he developed a strong friendship with Asuma Sarutobi. During this time, some underground organisation put a 30 million ryō bounty on his head. When six of the members tried a coup d'etat, he fought against them along with the other five members of their group. Only Chiriku and Asuma (and, in the anime, Kazuma, but not to the others' knowledge) survived the fight. Following the group's destruction, he became head monk at the Fire Temple, an elite monastery that is home to monks with special abilities. In the anime, it is revealed that Chiriku was once a student of Chūkaku. He apparently surpassed his master at some point.
