Ability

Background
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, to death.

Plot
Together with Tachihara Michizou and Ryurou Hirotsu, they raided 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.

During the three-way war between the Port Mafia, the Armed Detective Company and The Guild, she was sent along with Ichiyou Higuchi "for Dazai's protection", after Ougai Mori released Yumeno Kyusaku from confinement. Later, during Ougai Mori and Yukichi Fukuzawa's secret meeting, she—along with the other Black Lizard commanders—was also part of Mori's escort detail.

Trivia

 * It is clearly shown that Higuchi thought that Gin is a male, judging from her appearance. It is later revealed by Dazai that Gin is a girl and has a cute voice.
 * Higuchi mistakenly thought that she was Akutagawa's lover one time, when Higuchi saw a casually dressed Gin meeting up with Akutagawa.
