Azuma wears the default 1980s uniform, and since he is the President of the Science Club, he wears the "Red Armband of Leadership" with a resemblance of an Erlenmeyer flask on his left arm. He has messy grey hair that curls around his neck, many strands poking out from behind his head. His bangs are straight and curl inwards, covering his eyebrows. His eyes are grey as well.
