Kuzuryu is a small, skinny boy known for having a "baby face". Due to his rather childlike build, Kuzuryu usually displays an overly aggressive demeanor to claim that he is, in fact, a heavy-duty gangster. He has very short, dusty blonde hair with a pair of curved shaved lines on each side of his head. He also has freckles along the bridge of his nose and a birthmark near the mouth of his nose on the left side. His eyes are gold in color and he has permanent blush marks on each cheek.
