Akutagawa Ryunosuke is a character defined by a blend of ferocity, trauma, and unfulfilled yearning for approval. He does not get along with Atsushi. He coughs from time to time due to his illness. He has black hair with white tips and grey eyes, he wears black knight armour with his signature coat and undershirt beneath. He is a member of the Port Mafia, and after Bram's death he swore to be a knight even in this era. He can be sassy and use strange metaphors. He likes sweets, he can be blunt.
