Akame

Physical Abilities
Akame is often considered to be one of the strongest members of Night Raid, slaying even the strongest of enemies with minimal effort. Her hellish assassination training allows her combat prowess to be on par with those as powerful as the General rank within the military levels of the Empire, Esdeath herself acknowledging her strength. Akame is an extremely skilled master swordswoman, able to wield her Teigu Murasame with utmost dexterity and precision, able to slay numerous enemies, even highly skilled and powerful enemies with incredible ease. She easily slayed Izou a fellow master swordsman in combat and would have killed Tatsumi, if not for the statue his chief villager gave him before embarking on his journey. At her full strength, Akame managed to hold her own against Esdeath, a tremendously powerful master swordswoman and ultimately killed her with single precise thrust, plunging Murasame's shattered blade to stabbed directly into Esdeath's heart. Akame possesses tremendous speed, agility and reflexes, being able to dodge and counter-attack with deadly results, and is also skilled in hand to hand combat. She also gives off no killing intent at all when she fights, making it difficult for the enemy to sense her presence. According to Wave, she can run at Mach 1 (velocity of sound in the airflow which is approximately 340 meters per second). Like the other members of the Elite Seven, she is immune to most poisons.After being affected by Murasame's curse, her body feels heavy and she is no longer able to move like she once did.

Teigu
Akame carried the Teigu, One-Cut Killer: Murasame, a katana known for being coated in an immensely deadly poison that could kill those cut by it within seconds, as the poison itself had no antidote. The Teigu's trump card, the ability to strengthen its user with the power of its poisonous curse for a short amount of time, was revealed during the final battles against the empire. It is revealed near the end of the manga that Murasame's poison could only target one life at a time; using this to her advantage, she killed Tyrant without hurting Tatsumi.
