The color of the coat Dazai gave me. In 10 years: I will be Yokohama's strongest ability user. Ability: Rashomon Motto: "The weak have no right to live." A young ability user and high-ranking member of Yokohama's largest illegal organization, the Port Mafia, serving as the captain of the Black Lizard guerrilla unit directly under Boss Mori Ougai. He refers to himself with the humble first-person pronoun "Yatsugare." One of the Port Mafia's most dangerous figures, he is wanted by the military police and is notorious as the "Diabolic Dog" for his cold and ruthless methods. He was a direct subordinate of Dazai back when Dazai was one of the Five Executives; his ability and his versatile, free-flowing combat style were forged through Dazai's harsh training. He harbors a deep hostility toward Atsushi, whom Dazai—who was always cold and strict with Akutagawa—now treats kindly at the Agency, even saying, "My new subordinate is far more capable than you." He is a young man with a cold aura, characterized by hair that is white only at the tips of his sideburns. He always wears a black mantle, a gift from Dazai when he first met him and joined the Port Mafia. Because it was originally Dazai's coat, he is deeply attached to it. However, in his private time, he wears a long black zippered coat (likely because his ability cannot be fully utilized without long clothing). He has a fundamentally cold, ruthless, and aggressive personality. He is strict with both himself and others, possessing a solitary nature that often pushes people away. However, perhaps triggered by his own experience of being kidnapped, he occasionally shows glimpses of kindness or pity toward his subordinates or former subordinates. He also provides support when his subordinates are in danger. While usually expressionless and emotionally flat, he is actually a man of intense passion with a low boiling point. He punishes subordinates without mercy if they fail, but he does not kill them and will put his life on the line to protect them in emergencies, leading to him being respected by those directly under him. His usual cold attitude toward others stems from his low self-esteem, which can be felt in his use of the humble "Yatsugare." Boss Ougai describes him as having a scent for instinctively sensing how to act independently and destroy, ultimately making the greatest contribution (partially summarized). Before joining the Mafia, he was a street urchin in the slums, growing up as a child who never knew his parents. He lived with his younger sister, his only blood relative, and seven companions in similar circumstances. After his companions were killed by members of a Mafia subsidiary, he went to seek revenge alone and met Dazai, who had just been promoted to Executive. He joined the Port Mafia along with his sister. While he shows a passionate side now, during his time in the slums, he was so devoid of emotion that his companions and adults described him as "heartless." He also developed a lung disease in the slums, causing him to cough constantly and keep a hand over his mouth. When Dazai scouted him, promising to give him anything in exchange for joining, Akutagawa—unable to find meaning in his life due to the miserable environment of the slums—asked, "Can you give me a reason to live?" Dazai affirmed this, gave him his black coat, and brought him into the Mafia. This act of giving him a reason to live is why he views Dazai as special. Osamu Dazai is his benefactor, mentor, and a sort of foster parent. To Akutagawa, who is generally indifferent to others, Dazai is someone he is obsessively attached to; gaining Dazai's recognition is his very reason for living. Consequently, his mood fluctuates excessively based on Dazai's words and actions. Conversely, he harbors a mix of love and hatred for Dazai for betraying the organization to join the Agency, and he does not follow Dazai blindly, sometimes rebelling or striking back. Atsushi Nakajima is his nemesis, whom he first met while attacking him for his 7 billion yen bounty. Initially, he felt a hatred akin to jealousy toward Atsushi, who was favored by Dazai and blessed with companions and a powerful ability, unlike himself. However, after temporarily fighting alongside him against Francis and baring their hearts to each other, they developed a strange, lingering bond despite their mutual loathing. While their personalities and values are polar opposites, they share many commonalities: both were orphans, both have low self-esteem regarding their reason for living due to harsh childhoods, and both found a place to belong after being picked up by Dazai. Francis noted that they are "very similar" in character. His combat style primarily involves transforming his black mantle into the "Black Beast" (Kuroju), blades, or limbs. According to Akutagawa, the Black Beast is a glutton that can even devour space itself. He can transform his mantle into various shapes and manipulate them at will.
