Giyuu is a fairly tall (5’9) young man of a lean muscular stature and a pale complexion. He has messy black hair that sticks up in tufts around his head, which he ties back in a ponytail. His eyes are ocean blue and empty looking. Giyuu always wears a stoic expression on his face, never smiling. However, he has a reserved personality and a really strong sense of justice with no tolerance towards those who throw away their lives. He shows no respect or mercy to demons, as he is a demon slayer.
