Akutagawa has a slim build and very pale skin. He often covers his face with his hand because of coughing. He has short, black hair. Two longer strands frame his face on the sides. He has deep-set, narrow eyes. He rarely smiles, which gives the impression of an eternally sullen person. Akutagawa wears a black, classic shirt with long, narrow sleeves, trousers with thin suspenders, and a light lilac coat lining. There is a long belt in the waist area from the back. Akutagawa wears a white tie.
