Murasame is a Teigu in the form of a long katana that is used by Night Raid member Akame. The assassin group Night Raid recruits the young man to help them in their fight against the Empire to finish its corruption. Murasame is a poisonous blade that can kill a person with only one cut. Once the sword pierces skin, it injects a lethal poison into the victim, killing them within seconds. However, this ability only works on living organic beings that have a heart. The Murasame is constructed of stainless steel with a factory edge. The guard and wooden handle have a glossy red finish to match the wooden scabbard.
