Kazhil serves as the second-in-command within Youm's adventuring party. He possesses a tall, muscular frame with tanned skin and a bald head, marked by a prominent scar on the left side of his forehead; he typically sports a bandanna.

His background includes a history as a criminal, acting as Youm's right-hand man during that time. He was part of the 30-member Frontier Expedition Force. Following their encounter with the nation of Tempest, Kazhil and the other force members transitioned into becoming adventurers. They significantly contributed to Youm's efforts as a Champion by assisting in clearing the Migam Earldom of monsters emerging in large numbers from the Great Jura Forest.
