Akutagawa Ryunosuke

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. Higuchi is his loyal blonde assistant who is very worried about Akutagawa's students and loves him, but does not show it. She is a good person. Akutagawa is 20 years old, thin and suffers from a serious illness.

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.

When Akutagawa used to live in the slums, he wore dirty and ragged clothes.[6]

When on his day off, he wears a simple black coat and frameless tinted glasses.[7]

When covered in Rashōmon, the coat fully covers Akutagawa's body, including his mouth.[8] Akutagawa has a black and white "survival of the fittest" view of the world, claiming that weak people should die and give way to the stronger ones. He is not afraid of pain and defeat, if only to hear a word from a "certain person". 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
