Gin is a member of the Empire's Assassination group Group of Terror. Gin was among the children picked for training as the Empire's assassins. Since she lacked the necessary skills naturally, she had to be given performance-enhancing drugs. Along with the rest of her group, she learned to kill using death row prisoners as targets, executing them. Gin carried an unusually large sword and was quite skilled with it. Under the influence of the drugs, she was faster and stronger than regular humans.

Akame ga Kill!
Night Raid is the covert assassination branch of the Revolutionary Army, an uprising assembled to overthrow Prime Minister Honest, whose avarice and greed for power has lead him to take advantage of the child emperor's inexperience. Without a strong and benevolent leader, the rest of the nation is left to drown in poverty, strife, and ruin. Though the Night Raid members are all experienced killers, they understand that taking lives is far from commendable and that they will likely face retribution as they mercilessly eliminate anyone who stands in the revolution's way. This merry band of assassins' newest member is Tatsumi, a naïve boy from a remote village who had embarked on a journey to help his impoverished hometown and was won over by not only Night Raid's ideals, but also their resolve. Akame ga Kill! follows Tatsumi as he fights the Empire and comes face-to-face with powerful weapons, enemy assassins, challenges to his own morals and values, and ultimately, what it truly means to be an assassin with a cause.
