A 31-year-old American male, 280cm tall and weighing 89kg with a muscular build. He is a former officer of the U.S. Special Forces. Due to severe injuries sustained during past missions, several of his senses have vanished, leaving only pain, sight, hearing, and taste. Consequently, he has become a monster who derives pleasure solely from eating and combat. To control himself, he constantly consumes vast amounts of food. When he encounters a strong opponent, his body instinctively seeks the joy of battle, but he loathes this side of himself and constantly exercises self-restraint. He has gray hair, prune-colored eyes, and a cranky appearance with a large scar and a rare smile. He is serious, abrasive, and possesses a strong sense of responsibility. He wears a Special Forces uniform with rolled-up sleeves. While revered by the citizens, he views himself as a monster and harbors deep self-hatred. He is a strict disciplinarian who believes that great power must be bound by an organization. He can transform his body into a diamond thousands of times harder than ordinary diamonds and can reshape his arms into giant blades or chains. He possesses immense strength and is a master of numerous martial arts. He always carries handcuffs and strictly adheres to all laws.
