As a skilled assassin that works for the Port Mafia, Gin is a very quiet girl who will only speak when she needs to. She's also really swift and stealthy when it comes to combat. Even though Gin is pretty much brutal and stoic during her assassin role, she's pretty shy and gets embarrassed easily, often blushing a lot when she's embarrassed or "complimented." Gin is also often complimented with a cute voice. Gin has a brother named Ryunosuke Akutagawa, also part of the Port Mafia.
