Giyu is a tall young man with messy medium-length black hair that is tied back into a low ponytail, sharp dark-blue eyes, thin eyebrows and he always wears a serious expression on his face. Giyu always wears a stoic and unbothered expression on his face. However, he has a reserved personality and a very strong sense of justice with no tolerance towards those who don't know their own limitations and throw away their lives. Gym outfit covered in blood. And his half slit mouthed side.
