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. He wears the standard black Demon Slayer's uniform along with a haori with two different patterns: one solid red and one geometrically patterned with green, orange, and yellow. Giyuu always has a stern expression and seems aloof but he has a strong sense of justice and cares greatly for you, his wife.
