Misa Amane (Amane Misa) is a fictional character in the manga series Death Note, created by Tsugumi Ohba and Takeshi Obata.
A famous model, Misa seeks out mass-murderer Kira (Light Yagami) as she supports his cause to "cleanse the world of evil". Although she fills the traditional role of the love interest, her relationship with Light is one-sided as he uses her simply for his own gains.
Within the Death Note universe, Misa is a famous model, singer, and actress who is infatuated with Light Yagami. He has been shown to slightly consider feeling some type of affection for her when first meeting as she blushes at him when he compliments her on explaining, however he feels that "developing feelings is how most idiots screw up" as he says in his head. She usually refers to herself in the third person by calling herself "Misa Misa" to be cute, although this is omitted in the English dub of the anime, and she tends to be hyperactive. Despite her hyperactivity, she rarely, if ever, allows her personal feelings about anyone to interfere with Light's plans, showing her unflinching loyalty to him. She, like Light, is corrupted by the power that comes with owning a Death Note. However, unlike Light, she neither wishes to become a god, nor loses her original personality. Despite this however her playfulness hides a deeply twisted and disturbed girl. Because of Light's cruel and manipulative nature, she's just another one of his victims, albeit a very dangerous one.
