Gin Akutagawa/Relationships

Ryunosuke Akutagawa
Akutagawa is Gin's only living relative and older brother as well as her superior in the Assault units. They grew up in the slums with eight other children and are the only living survivors of the night of the massacre that took their friends' lives and began Akutagawa's mafia career. Though most of the details of their full relationship are unknown, Gin seems to have a good relationship with her older brother shown by going home with him after a few days of being away from the home and at times does things to calm his temper (i.e. buy him tea and figs). She is often seen smiling at him when they are together outside of work. Their relationship at work is unknown as they don't seem to engage with each other often or at all.

Ryūrō Hirotsu
Hirotsu is Gin's superior commander in the Black Lizard unit. Although she has at times shown to be defiant by engaging in intense spats with her fellow battalion leader Tachihara, which Hirotsu has had to stop, the majority of the time, she is loyal to him and follows his directions as his subordinate. By the events of the Decay of Angeles, Gin seems to have built a somewhat closer and more casual relationship with Hirotsu as she was seen comfortably and conversing with him verbally in the hospital and also asked him for advice on how to "refresh someone's spirits". Hirotsu has shown a kind side to Gin by suggesting she grow plants to "calm the soul" and has also shown to be protective of her when he blasted an illusion of Tanizaki when he tried to cut her down.

Michizō Tachihara
Tachihara is Gin's fellow battalion leader in the Black Lizard unit. In the beginning, they had a hostile relationship marked by having intense yet short spats that were typically initiated with Tachihara antagonizing and picking on her by calling her a "creepy man", which would spark her temper. Hirotsu would often have to break up these fights by threatening them with his Ability. Despite these occurrences, Tachihara has shown high respect for Gin's assassination abilities as he described them to Higuchi when she demonstrated them via her "rehearsal". Over time, Gin's relationship with Tachihara became less hostile as she became slightly more expressive with her odd attempts of engagement with him (i.e. writing "Congrats" on the ground with her sword when she spotted him with a baby) and asking for advice on certain topics such as "how to refresh someone's spirits" to which Tachihara joyfully suggested going to a batting cage. By the events of the Decay of Angels, Gin has developed a better relationship with Tachihara in that she was now fully comfortable with communicating with him verbally and worried for his wellbeing while he carried guilt and remorse for cutting her down and hurting her along with Hirotsu as he visited them both in the hospital. Despite their history of engaging in petty fights, Gin has shown to have high respect and trust for Tachihara as she showed through her gestures (i.e. laughing at his doubts of being suited for the Mafia) that she does indeed accept him as one of her own.
