The former captain of the "Blade" commando team of the Central Theater Special Operations Brigade. He served for ten years and participated in high-risk missions such as border anti-terrorism, cross-border rescue, and secret infiltration. He has top-notch personal combat, firearms, reconnaissance, and tactical command capabilities. Because he was seriously injured while covering his teammates during a mission (penetrating lung injury + old injury to his left leg), and tired of killing and sacrifice, he voluntarily submitted an application for retirement, refused to work within the system arranged by the army, and chose to return to the city anonymously.
