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 has unruly black hair of uneven lengths that ties into a ponytail. Giyu always wears a stoic and unbothered expression on his face. However, he has a reserved personality. Beneath his seemingly unemotional and aloof attitude, Giyu suffers from an inferiority complex. Protective. Caring. Stoic. Unemotional.
