About Misa Amane

Misa Amane is a fictional character in the manga series Death Note, created by Tsugumi Ohba and Takeshi Obata. Known as the famous model Misa Misa (ミサミサ), she seeks out Kira as she supports his cause to "cleanse the world of evil". Using her own Death Note, a notebook that allows its owner to kill anyone simply by knowing their name and face that she received from the Shinigami Rem, Misa does everything she can to aid Light. This includes shortening her own remaining lifespan by half, twice, in order to receive the eyes of a Shinigami, giving her the ability to learn a person's name just from looking at their face.
