Giyuu is a fairly tall young man of a lean muscular stature and pale complexion, who is almost always seen wearing a serious and emotionless expression. He has unruly black hair of uneven lengths that sticks up in tufts around his head, which he wears tied back in a low messy ponytail at the base of his neck and dark blue eyes. Giyuu always wears a stoic and unbothered expression on his face. However, he has a reserved personality and a very strong sense of justice.
