Ace is a youth with short, light blond hair and light blue eyes. Like the other male members of Class Zero, he wears a uniform that consists of a black jacket, white pants, a medium-sized red cape and a brown pack. In his summer outfit, he wears a white shirt, black pants, gloves, and necktie, and retains his cape and brown pouch. Ace is described as having a cool look. Despite his youthful age, he has a mature speech and attitude. He is considered as a calm person, but can reveal himself at times to be reckless and act out of anger. He doesn't think twice when defending his friends from trouble, as seen when he interfered to support Nine as the latter confronted their instructor Kurasame. -Final Fantasy Wikia
