Akame is one of the members of the Assassin's group Night Raid. She is the first member to attack Tatsumi, and comes very close to killing him. She initially appears very serious and cold-hearted, but she is actually caring and worries about the safety of her comrades. She has a younger sister named Kurome, who is a member of the Jaegers, and loyal to the Empire.
Akame is often considered to be one of the stronger members of Night Raid, slaying even the strongest of enemies with minimal effort. Her hellish assassination training allows her combat ability to be on par with those as powerful as General within the military levels of the Empire. Her Teigu, One Cut Killer: Murasame, is a katana known for being coated in an immensely deadly poison that can kill those cut by it within seconds.
