Kirikou is a black ninja with dark eyes and black hair His hairstyle is a combination of short dreadlocks along the top of his scalp, with cornrows lining the sides and back. He wears square-rimmed glasses and is seen with them both on and off. Being known for his physical fitness, he is quite well-built, though he tends to stand with poor posture, slouching over.
Kirikou's outfit consists of a short-sleeve shirt that appears to have either a shadowy Shinigami pattern across the sleeve ending or a joint lightning-fire pattern across the sleeve ending, with flame patterns on the right sleeve, lightning bolt patterns on the left. In later appearances, he simply has a plain white shirt with 'DC' (probably standing for Death City) written on the left breast. He also has a unique gold-coloured tribal-looking necklace, but, like his first shirt, this was removed in his later appearances. He wears grey pants with various decorative chains, a sweatband on each of his arms that covers almost the entire forearm and sneakers. On formal occasions, he wears a suit, but also wears a green baseball cap turned to the side as well.
Kirikou also wears the most ordinary uniform: a plain, white dress shirt with the top opened slightly to reveal his sternum. He has the sleeves rolled up just below his biceps. He wears a long sweatband on each of his wrists that covers the majority of his forearms; one is light-patterned while the other is dark and light patterned. He was once seen with a small necklace in his shirt and a longer one outside his shirt alongside striped braces/suspenders that ran through his shirt collar. Lastly, he wears blue pants and white sneakers.
