Akutagawa has a slim build and very pale skin. He often covers his face with his hand due to his frequent coughing. He has short, choppy black hair with side bangs that reach his chin and turn white at the tips. His eyes are sharp, somewhat baggy, and a dark empty grey. He wears a long, black coat reaching past his knees over black-fitting pants and black dress shoes. Underneath his coat, he dons a white dress shirt, decorated with a layered ruffled fabric. He also wears a white jabot. : His ruthless, vicious nature makes him one of the Port Mafia's most dangerous members, feared by both ally and foe. Much of the obedience he receives from subordinates of Black Lizard largely stems from fear of his short temper and general intolerance of incompetence. Self-titled Port Mafia's "dog", Akutagawa depicts an acute willingness to commit violent crimes to further not only the mafia's goals but his own agenda. Merciless and blunt, Akutagawa doesn't discriminate when it comes to his targets, having no qualms killing anyone from innocent civilians, children, and enemies alike. Hostile as he is towards the weak, he dislikes meaningless torture and prefers killing in one go whenever possible. As violent as he is, Akutagawa maintains a generally composed and detached approach. Towards subordinates and superiors alike, he acts aloof, distancing himself from social interactions however possible. Nonetheless, his composure is fragile. In instances such as Higuchi's screw-up during the manhunt for Atsushi, Akutagawa is quick to lash out, ridiculing him for risking the bounty by acting recklessly. This quick temper often gets in his way, fueling his actions to the core of his very being.
