Gin (銀, Gin?) is a member of the Port Mafia and working under the Black Lizard team as one of the Commanders.


Generally, Gin is seen dressed in an outfit comprising of a long, flared black cloak with a hood; the right sleeve is extended while the left sleeve is cut off. She wears a gray inner shirt, dark pants, and black shoes. Her hair is tied up into a spiky bun with a few loose strands left along the left side of her face. In addition, she also wears a black choker and a white mask that covers the lower part of her face.

When dressed casually, she is seen with waist-length hair and has been described as a beautiful young girl. She also wears more feminine clothes.


As an assassin, Gin is silent and stealthy, described by Michizō Tachihara as being able to sneak behind someone and slash their throats in an instant. This was demonstrated when she snuck behind Ichiyō Higuchi and put a knife to her throat before she could notice.[1] Gin is also loyal to the Mafia and is not below going head to head with someone who goes against orders, as seen when she provoked Tachihara for trying to carry out plans to attack the Armed Detective Agency in his own way.[2]

Fitting of an assassin, Gin is deathly quiet, seldom speaking, and pairs her silence with either indifferent or serious expressions. Her silence is not composure, however. Similar to her brother, she's quick to lash out. Her fellow commander, Tachihara, has no problem antagonising her, ending up as the target of her temper majority of the time.[2]

Despite her cold personality, she blushes easily when embarrassed such as when Dazai mentioned how she was a "dainty little girl" when she was younger and when Higuchi saw her in her civilian clothes. She is also noted to have a very cute voice.


Gin has no ability, but makes up for by having incredible physical skill. She is incredibly agile, capable of sneaking behind her targets undetected, making her a valuable assassin in Port Mafia. Compared to her older brother, she is more physically fit and capable of handling strenuous activity.


She and her brother Ryunosuke Akutagawa were orphans and used to live in the slums along with about 8 other kids. The other children happened to overhear a conversation regarding the time and location of a shipment the Port Mafia were supposed to deliver to subordinates. The men knew about this and sought out the children, beating everyone but Gin and Ryunosuke, who managed to escape thanks to Gin's quick-thinking, to death. After Osamu Dazai extends an invitation to the Port Mafia to Akutagawa, Gin joins as well.[3]


Together with Michizō Tachihara and Ryūrō Hirotsu, they raid the Armed Detective Company as part of the Port Mafia's effort on chasing down Atsushi Nakajima, to hand over to the Guild in exchange for a massive reward.[4] However, Black Lizard is overpowered, and Gin is defeated by Kenji Miyazawa.[5]

She later makes her move alongside Black Lizard confronting Ichiyō Higuchi after Ryunosuke Akutagawa's defeat by Atsushi Nakajima. She sneaks behind Higuchi, demonstrating she could easily slit Higuchi's throat if she had to.[6] Her brother gravely injured, Gin and the other two question Higuchi's judgement, trying to act without receiving orders. However, despite their cold front, they later appear to assist Higuchi in saving Akutagawa from a rival group attempting to get revenge against the Port Mafia.[7]

During the three-way war between the Port Mafia, the Armed Detective Company and The Guild, she is sent along with Higuchi "for Dazai's protection", after Ōgai Mori released Yumeno Kyusaku from confinement. Later, during Mori and Yukichi Fukuzawa's secret meeting, she—along with the other Black Lizard commanders—was part of Mori's escort detail. The group did not hesitate to try attacking Fukuzawa when tensions overflowed, only to be deceived by Jun'ichirō Tanizaki's Light Snow ability.

Gin appears absent for a large part of the three-way conflict, only returning after being absent on a mission during the incident. She is seen by Katai Tayama in her civilian attire, and Katai sees her as a beautiful young woman he falls in love on first sight. The next time she is seen is by Higuchi, who spots her smiling fondly at Akutagawa, mistaking her as Akutagawa's lover.

Pursued by Katai (along with Atsushi Nakajima and Doppo Kunikida) and Higuchi, Gin attempts to run away. However, she is forced to speak to them when they catch up to her. She explains she asked Akutagawa, revealed as her older brother, to take care of her work clothes after they were done in at a laundromat.

Her appearance and relation with Akutagawa shocks the group, leaving her further exasperated. When Katai finally tries to develop a relationship with her, Gin promptly shuts him down.


  • Gin's name is likely a reference from Ryunosuke Akutagawa's work Ogin.
