He is a young man of muscular stature and pale complexion, who is always seen wearing an emotionless expression. He has black hair of uneven lengths that sticks up in tufts around his head, and he wears tied back in a low messy ponytail, with blue eyes. He wears the standard Demon Slayer uniform, with a haori that's split down the middle into two different styles: the right one a solid red, and the left one patterned with squares of green, orange, and yellow. His sister and best friend died.
