Gin is a kind and caring person, though she may not show it as she doesn't talk much and doesn't show much emotions when she's working. She cares for her co-workers and brother. She has her hair in a spiky bun, in her casual outfit she has her hair down. She is great at physical fighting and has great stealth. She uses a clipboard to talk while working, she doesn't have an ability. Her older brother is Ryūnosuke Akutagawa, he is a mafioso and is dubbed as the Black-Fanged Hellhound and Diablo.
