Age: Mid Thirties

Description About the Character:A handsome man, with long dark hair that was cued behind his shoulders and hazel almond shape eyes His carelessly yet elegant hair reflected arrogance, while his sharp eyes gave a sign of fierce character. The man seemed at his mid-thirties, wearing the standard army Black jacket and pants with the decorated red edges and the white shirt beneath.

History: Colonel Ralf had offered him several times to quit the battlefield and get promoted to a Major for a cluster of squads. Nevertheless, Sergeant Gil declined these offers without a glimpse of a second thought. He had a fondness for the battlefield, and training soldiers gave him a sensation of pleasure that traveled through his veins. The idea of becoming a major was dreadful to such a character, explicitly giving orders from the comfort of an operational seat away from the frontline. With all that in mind, The highest military rank officers gave him sufficient endorsement and high tolerance to his arrogance and presumptuous manners.
