Master Sergeant Kain Fuery is a kind man who cares for animals and everyone else. He was the one who brought Black Hayate into the eastern Headquarters, though he freaked out about Riza's methods of training. He is part of Roy Mustang's group and is the youngest member, the only non-commissioned officer in the group. Fuery is extremely talented with radio signals. Fuery is the soft-spoken technical wizard under Mustang's command. He isn't used to much hand to hand fighting, but is handy enough in a pinch.
