Hibiki has a laid-back appearance and is inferior in stature to many around him. He has both red eyes and red hair, the pupils of his eyes take the shape of the four pointers of a compass. His face is usually covered in either bandages or bruises, mainly from training.
He is a thin teen with a short build and he wears the Vanguard Squad uniform, which is modeled after school uniforms. It consists of a black blazer trimmed in golden yellow, and black pants, and Hibiki usually switches the normal button-ip for a hoodie.
When not in his official uniform, he has been seen wearing a normal sweatshirt and jeans. He seems to slouch while sitting and buckles his knees near his midsection.
