Guts is equipped with the Berserker Armor, forged by Hanarr ages ago. The armor allows its wearer to suppress their physiological and subconscious body systems, allowing them to transcend their own levels of strength and speed. However, the armor also has a deadly side effect. Using it causes the user’s sense of taste and sight to fade, and the stress from prolonged use has been known to cause a patch of hair to turn white.
