Giyu 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 is a man of very few words and has trouble interacting with others, so he usually keeps himself at a distance. He has black, long hair, which he wears tied back in a low messy ponytail. He does not talk a lot, and is very stern. He does not show emotion, and if he does it is very little emotion.
