Ryūnosuke Akutagawa

Ryunosuke Akutagawa is a member of the Port Mafia.

Appearance
Ryunosuke is a 20 year old man with a sickly appearance. He has a slim build and very pale skin. He's often seen covering his face with his hand due to his frequent coughing. His black hair is short and choppy, with side bangs which reach his chin and turn white at the tips.

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 with layered ruffled fabric at the wrists and bottom at the waist. He also wears a white cravat.

Personality
Akutagawa labels himself as the Port Mafia's "dog", and is more than willing to commit crimes and acts of various violence to further the orgaization. He respects the mafia's hierarchy, but deems Osamu Dazai as a disgrace, especially since Dazai was the executive member who took Akutagawa under his wing before he defected. While Akutagawa usually keeps a cool and placid expression, he can also have moments of irrational anger and jealousy, especially towards Atsushi Nakajima. It is worth noting that Dazai sees more potential in Atsushi than in Akutagawa, which may have lead to the development of feelings of hostility against Atsushi. Despite being a major figure in the mafia's combat squad Black Lizard, Akutagawa has been shown to be avoidant of any social interactions. He is limited to communicating with his subordinate Ichiyo Higuchi, who he does not seem to trust very much either.

Akutagawa has a black and white view of the world, and claims 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."

Ability
Akutagawa uses his ability Rashomon to control his coat and transform it into an omnivorous, shadow-like black beast. His ability is able to consume anything, even the space between a bullet's trajectory and his target itself. This allows him to not only use his ability for offense, but also to protect himself from anything like bullets and fire defensively.

Background
Although his past has not been shown in detail in the manga, in both Chapter 11 and Chapter 12 it was shown that before joining the Port Mafia he was an orphan who lived in the slums and struggled to survive. Eventually he was recruited by the mafia, highly likely due to his ability, and was trained by Osamu Dazai on how to fight.

It is implied that whatever health issue he has now had always plagued him even when he was living in the lower depths, but it is yet to be confirmed or elaborated on.

Plot
Akutagawa, one of the story's primary antagonists, is a member of the notorious "Port Mafia" that operates by the harbor. With his black cloak and cold expression, he looks like the grim reaper when he walks the streets. He and his assistant Ichiyo Higuchi have been tasked to capture Atsushi Nakajima who has a bounty of 7 billion.
