Tsubusa

Tsubusa is a chuunin from Sunagakure. Tsubusa has short, black hair and most of his face is concealed by a mask. He wears the standard attire of the Suna-nin, which includes its forehead protector, its flak jacket, and a turban along with a metal face guard. He is said to have excellent eyes and can discover enemy forces several miles away. It was due to this ability that he was tasked to patrol at Sunagakure's gate and was indeed the first one to discover the approaching Akatsuki members, even when there were many other jounin and Anbu present.
