Akame

Akame also known as Akame of the Demon Sword Murasame, is one of the members of the assassination group, Night Raid and one of the main protagonist, along with Tatsumi (and the title character) of the story. Akame is a young girl who, before meeting Tatsumi, establishes herself as the Empire's top ranking assassin. Akame's cold-hearted and serious demeanor stems from her hellish training the Empire forced her and her sister through after being sold by their parents. After being tasked one mission to assassinate former general Najenda she is convinced by her to not only spare her but also to instead join her crusade against the Empire by becoming a member of Night Raid. Her treason sparks an intense rivalry between fellow assassin and sibling Kurome, along with a mutual desire to be the one to end the other. 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. In the anime, during a last confronting battle with Esdeath, Akame uses the hidden ability of her Demon Sword Murasame which grants her superhuman powers, ending in a victory after cutting Esdeath and killing her with the One Cut Killer. She takes all the blame of the assaults done by Night Raid so she could clean Najenda's name. Later she is seen wandering around in the desert outside the Kingdom slaying bandits and mercenaries.
