Kira In Death Note

Kira is the figure known by causing the deaths of criminals. The name Kira was created by the public in response to Light Yagami's initial use of the Death Note, and various members of the public view Kira as a god. Various Death Note users act as Kira, but their identities are unknown to the public so their actions are viewed as being committed by one entity. This is the list of Kiras which are viewed as one Kira by the public. They are only referred to as these alternate titles by various individuals investigating the Kira case.

Light Yagami 

Also known as: Kira
Light Yagami is the main protagonist of Death Note. He is portrayed as a brilliant but bored genius who finds the Death Note, an otherworldly supernatural notebook that allows the user to kill anyone by knowing their name and face, after it is dropped by the Shinigami Ryuk. Frustrated by the status quo of a world he deems to be rotten, Light uses the Death Note to kill those whom he deems morally unworthy of life, masterminding a worldwide massacre as the vigilante Kira. Over the course of his efforts to become the god of a world free of crime, Light is hunted down by a special task-force, headed by an enigmatic consulting detective known as L.

Misa Amane 

Also known as: Second Kira

A famous model, Misa seeks out Kira (Light Yagami) 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 lifespan by half, twice, in order to receive the eyes of a Shinigami, giving her the ability to learn a person's name just by looking at their face. Although Misa fills the traditional role of the love interest, her relationship with Light is one-sided as he uses her simply for his own gains.

Kyosuke Higuchi 

Also known as: Yotsuba Kira
Higuchi is an executive of Yotsuba Corporations and the only person, besides C-Kira, to hold the title of Kira who is in no way connected to the original Kira, Light Yagami. He obtained a Death Note from Rem after Light and Misa relinquished their Death Notes and their memories to avoid conviction. He only judged criminals for a short time, until Light and Misa were freed from imprisonment due to the deal Rem was told to offer: "kill criminals and you may write any other names you wish". He later used the Death Note for selfish reasons such as promotion and furthering the business of Yotsuba. Higuchi was later exposed as the new Kira and was arrested. His Death Note was given to Light, who recovered his memories as Kira and killed Higuchi before he was even put in a police car.

Teru Mikami 

Also known as: X-Kira

Teru Mikami is a criminal prosecutor, a fanatical supporter of Kira, and the fourth Kira. When Light needs a new Kira proxy to hide his identity, Mikami is selected as the new Kira by Light, purely based on his intuition. Since childhood, Mikami has had a strong sense of justice, but his views have become warped due to years of bullying and trauma. Mikami wishes to punish those he considers to be evil (which, to Light's dismay, includes unproductive people and reformed criminals) and worships Kira as a god. Mikami mutters the word "delete" repeatedly to himself while writing in the Death Note.

C-Kira
Also known as: Cheap Kira
Their true identity never revealed, C-Kira appears in the one-shot set three years after the end of the series. C-Kira's Shinigami was Midora, and the origin of the Death Note which C-Kira used is unknown. C-Kira would kill the elderly, suicidal, immobile and any others who wished to die. C-Kira gained these sources via the Internet, and once by killing the members of the audience of a live television program who begged him to kill them. C-Kira's reign was short. He was talked down by Near (now known as L) who made it clear that he was not going to even bother to investigate the case. C-Kira then wrote his own name down in his Death Note and died. The name of C-Kira was used by Near to mean "Cheap Kira," as Near has a very low opinion of the person.

Minoru Tanaka
Also known as: A-Kira
Minoru appears in the Never Complete One-shot set ten years after the end of the series. He is given a Death Note by Ryuk, who hopes to find a human similar to Light who will use the Death Note, entertain him, and feed him apples. Rather than use the notebook himself, Minoru elects to hold an international auction and sell it to the highest bidder. He dies of a heart attack after selling the notebook to the United States of America, unaware that the King of Death has after-the-fact created a new rule that anyone who tries to sell a Death Note will be killed. While active as Kira, Minoru is given the nickname "a-Kira" by Near, referring to his intention of auctioning off the Death Note.
