Kira

Kira normally would refer to Light Yagami, however, the title of Kira can also be used to describe any human user of a Death Note. The title or entity of Kira is one of the two opposing forces in Death Note, the other being L.

Personality
Most Kira in the series have a strong sense of justice and were usually supporters of the entity "Kira" before becoming Kira and using a Death Note themselves. Misa Amane and Teru Mikami, the Second and Fourth Kira, respectively,  even went as far as to say they worship Kira. Kira also tend to have strong motivation and drive. To be called Kira, one must use a Death Note to kill. As such, most Kira are quite educated in the rules of Death Notes and Shinigami. Another trait many Kira have is having Shinigami Eyes, allowing all the information a person would need to kill using a Death Note.

List of Kira
This is the list of Kira, in order, with a description of their time as Kira.

Light Yagami - Known simply as Kira, Light was the first human to use a Death Note and holds the title of the First Kira. As such, he was the smartest and most committed to his goals in becoming "God of the New World". L was naturally Light's enemy, opposing his judgement of criminals. Light held the title Kira the longest, avoiding capture better than any other Kira. Even after joining the Kira Task Force, being imprisoned for 50 days and even loosing and regaining his memories of the Death Note, Light was still able to evade being caught. After L Lawliet died, Light assumed the title "L", becomeing virtually invincable for three years. Then, when Near and Mello came onto the scene, their combined effort was enough to expose Light as Kira. Light seemingly lost his sanity after Near told him he "lost", having to be shot several times by Matsuda. Light's name was then written in his Death Note by his Shinigami, Ryuk, and he died of a heart attack.

Misa Amane - Usually called the Second Kira. As her name implies, Misa was the second human to use a Death Note. Misa obtained her Death Note from the Shinigami Rem. Misa was initially an extreme Kira supporter, due to the fact that Kira passed judgement on a man who murdered her parents. Misa is arguably the least committed to Kira's goal, but helps try to achieve it by extension to her love of Light Yagami. She is also the the least intelligent of all five Kira, and as such usually takes Light's orders rather than making her own movements. All in all, she was merely a tool to Light, losing her memory and making Kira's judgments many different times to evade suspicion of Light. Misa was the only living Kira after Light's death. She had relinquished her memories of the Death Notes shortly before Light died, and since the SPK was now in possession of both Notes, there was no way for her to ever regain her memories. Misa mourned Light's death for the rest of her life. Finally, she committed suicide one year later, on Valintine's Day by shooting herself in the head.

Kyosuke Higuchi - Called the Third Kira or the Yotsuba Kira, Kyosuke is an executive of Yotsuba Corporations and the only person 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, He then used the Death Note for selfish reasons such as promotion and furthering the business of Yotsuda. He was caught shortly after. After he was arrested, his Death Note was given to Light, which gave Light his memories back, and Light killed Kyosuke before he was even put in a police car. It is heavily implied that Kyosuke was not even aware of the original Kira's goal.

Teru Mikami - The Fourth Kira, or X-Kira (what Near calls him) is Teru Mikami. Mikami has always had a strong sense of justice and is the most understanding and committed to Kira's goal, second only to Light. Mikami recieved the Death Note from Light. After suspicion of Misa rose again, Light gave Mikami the Death through Kiyomi. Mikami carried out Lights orders as perfect as possible. Mikami worshipped Light possibly even more than Misa, being the only person to address Light as "God". He was willing to be the scapegoat for Light and Kiyomi, carrying out judgments in a fake Death Note to keep suspicion away from Kiyomi, who was the one actually carrying out judgements. Despite this devotion, it was a mistake made by Mikami that exposed Light as Kira. Overwelmed with self-loathing for what he had done, Mikami stabbed himself in the torso with his pen and bled to death.

Kiyomi Takada - The Fifth Kira, Kiyomi Takada, never actually touched a whole Death Note, but instead was regularly given pages torn out of Mikami's Note. While Mikami was using a fake Death Note to keep the SPK and the Kira Task Force busy, Kiyomi is using the torn pages to carry out real judgments. But ultimately, after she is kidnapped by Mello, Light didn't want her to be caught with the pages or try to explain Mello's sudden death, so Light killed her by having her set herself on fire, thus destroying the pages and killing her. Kiyomi was one of the smarter individuals to hold the title of Kira. It is unknown if he was serious or just manipulating her, but Light at one point offered Kiyomi the position of "Goddess Of the New World".
