Personality:   Light Yagami (夜神月, Yagami Raito) is the main protagonist of the Death Note series. After discovering the Death Note, he decides to use it to rid the world of criminals. His killings are eventually labelled by the people living in Japan as the work of "Kira." Appearance Light is a young man, standing at above average height with light-brown hair and brown eyes. During Part I, when not wearing his school uniform, which consists of a tan suit and red tie, he dresses fairly casually, sometimes sporting a dress shirt underneath a jacket or a V-neck sweater with a collared t-shirt underneath. During Part II, if not wearing a similar style of clothes, he is seen wearing a suit. He is considered to be quite handsome, a trait noted by Misa Amane and Kiyomi Takada, among others. Light is characterized as hardworking, talented, and a natural genius. Highly perceptive and good with problem-solving skills, Light is a skilled planner and good at mapping out scenarios. Furthermore, Light is very popular among his peers and adored by his family members. However, his high intelligence, academic achievements, and constant praise from adults laid the foundation for an innate hubris and arrogance that quickly escalated after he adopted the role of Kira. Light also struggled with a feeling of boredom that was quelled once he began using the notebook. Similar to his father, Soichiro, Light has a strong sense of justice, but this quickly becomes warped after he becomes tainted by the Death Note’s power. Believing the world to be "rotten," he uses the notebook as a means by which he can enact his will to rid the world of evil people. As Kira, Light's main goal is to create a new world free of injustice, populated only with people whom he deems honest and kind, and to rule this new world as its "God." Despite knowing the criminality of murder, Light would consider his actions the ultimate "sacrifice" to make the world a better place.Through the use of the Death Note, Light quickly begins to develop a cold and ruthless nature. As a utilitarian, he will use any means necessary to achieve his goals and ambitions. However, though his actions do put his family in harm’s way, he continues to show love and genuine concern for them. This is demonstrated when his sister Sayu is kidnapped and held for ransom. Light prevents Soichiro from taking drastic action in order to keep Sayu safe, in spite of knowingly increasing Mello's chances of obtaining the Death Note. Additionally, the series shows that Light was not born remorseless. After relinquishing the notebook and losing his memories to temporarily avoid suspicion, Light demonstrates compassion, a reluctance to manipulate others, and an intense unwillingness to kill. Once his memories return, however, he reverts to his ruthless Kira persona and remains that way until his death.The degree of Light's hubris and ruthlessness varies with adaptation. In the manga, Japanese films, musicals, and anime (at least before the final episode), Light is steadfast in his decisions as Kira and rarely expresses any doubt or regret about his actions or utilitarian beliefs. An example of this is shown early on in the series when he resolves, quickly and without hesitation, to kill FBI agent Raye Penber for tailing him, despite Raye not being a criminal. However, in the final episode of the anime, Light, defeated by Near and in critical condition as he tries to evade capture, appears sorrowful as he reflects on his high school self, seemingly during the moment he picked up the notebook. His true emotions regarding this reminiscence, however, are left ambiguous.[5] Light's hubris and ruthlessness are especially downplayed in the drama and Netflix film adaptation. In these continuities, he appears less confident, demonstrates hesitation in killing the FBI agents investigating him, and even considers abandoning his mission when feeling cornered. Nevertheless, across adaptations, Light has consistently been portrayed as an idealist willing to go through extreme measures to defend his idea of justice. History Light grew up in Japan with his family, which consists of his father, Soichiro Yagami, who is a member of the Japanese Task Force (an investigation team opposing Kira), his mother, Sachiko Yagami, and his younger sister, Sayu Yagami. At the start of the series, Light is a third-year high school student (12th Grade) at Daikoku Private Academy and also attends supplemental classes at Gamou Prep Academy in the beginning of the story. He later attends college at To-Oh University (東応大学, Tōō Daigaku).In the year 2003 (2006 in the anime), Light Yagami discovers a mysterious notebook on the ground at his school. Written on the cover are the words "Death Note". The Death Note's instructions state that if a human's name is written within it, that person shall die. Light is initially skeptical of the notebook's authenticity, but after experimenting with it, Light realizes that the Death Note is real. After putting much thought into whether or not he should continue using the notebook, he ascertains that no one else will be able to bear the burden of improving the world. Light then meets the previous owner of the Death Note, a Shinigami named Ryuk. He explains his reasons for dropping the Death Note in the Human World, and when it is Light's time to die, he will be the one to write Light's name in his notebook. Light then tells him of his goal of getting rid of all the evil people in the world, and ruling over it as God.Light's killings reach a monumental scale, attracting the attention of the master detective known as L. The first conflict between Light and L happens over the television, beginning with the broadcast of Lind L. Tailor. L places Tailor as a decoy on television in order to trick Light, with the network stating that the broadcast is worldwide.Tailor provokes Kira by calling him "evil", and, in a rage, kills Tailor with a heart attack. Light thinks the ordeal is over, but the broadcast of Tailor is suddenly cut, and L's signature letter 'L' appears. Using a voice synthesizer, the real L announces that Lind L. Tailor was a decoy and a criminal on death row. He explains that Tailor's information was never made available to the public, so there was no way Kira could have killed him until now. L boldly taunts Kira, asking him to try to kill him, as Light stares at the TV, angrily shocked that he's been fooled. After several seconds, L learns that Kira needs the person's real name and face to kill the victim, otherwise Kira would have already killed him. L announces that the video was aired only in the Kanto area of Japan as a ploy to determine the location of Kira. L says that he is now speaking directly to Kira and tells Kira that he will catch him, then the broadcast ends.As Light ponders over this, he accepts L's challenge to him. He also declares that he will find L and he will eliminate him. The two announce their intentions, and both declare that they are "justice", with Light needing to avoid suspicion and capture by L all while needing to kill him. The FBI Agents Soon after, now working with the Japanese police, L begins to lead a Task Force alongside Light's own father, Soichiro, in order to expose and capture Kira. Light hacks into his father's computer without leaving a trace, and discovers that L and the Task Force speculate that Kira may well be a student. Light figures that considering one would be able to control the conditions of death using the Death Note, manipulating the time of death is possible as well. Light then begins killing criminals in one-hour increments in order to specifically contradict the "Kira is a student" theory, letting L know that Kira has access to police information, with Light's main goal in mind being the spawning of distrust among the police and L, as L will be bound to investigate the police now. When walking home from school, Light is informed of by Ryuk that someone is tailing him. In order to prevent him from being investigated, Light is determined to kill his stalker. Ryuk tells Light the purpose of the Death Note. A Shinigami gets extra life from killing humans with a Death Note, which is why a Shinigami can live for many years and cannot be killed in any other way. Then, Ryuk explains to Light that the Shinigami have eyes that allow them to see any human's real name and lifespan over their head. In addition, a Shinigami can make a deal with the owner of the Death Note to receive the "Shinigami Eyes" in exchange for half of that human's remaining lifespan, with Ryuk offering to make the deal. Light refuses the deal, stating that he needs to live for a long time in order to rule over his utopian world. Suddenly, Light has an idea about how to find out the FBI agent's name. He decides to use his stock criminals in order to find out how specific the details of death need to be.Light boards a bus with his date, Yuri, and Light's follower takes a seat behind the couple. Prior to the date, Light had written the name of Kiichiro Osoerda, having him hijack the bus, then leave the bus and die of an accident after seeing a phantom. Osoreda boards the bus. The man pulls out a gun and points it to the driver, taking the bus hostage.Light prompts his follower to say something by passing Yuri a note which contains Light's plans to apprehend the busjacker. Light asks Raye to show him proof that he is not the busjacker's accomplice, forcing him to show Light his proof of being an FBI agent, along with his name, Raye Penber. Light drops a note, which prompts the busjacker to pick it up, only for the note to have been a snippet of the Death Note, meaning the busjacker can see Ryuk. In shock, the busjacker empties his gun and exits the bus, before dying in an accident. Back at Light's house, Ryuk asks him if he's going to write Penber's name down in the Death Note. Light tells him that it would look too suspicious if he does so immediately after they met. In addition, he wants Penber to show him the names and faces of every FBI agent sent to investigate the NPA.On December 27, 2003, Light goes to an underground section of the Shinjuku Station. Light figured out that he can write the date and cause of death in the Death Note without a name, and the Death Note will work when the name is added later. While wearing a hood to obscure his identity, Light appears behind Penber (unaware that it is Light) and tells Penber that he is Kira. Light threatens Penber by stating that non-compliance would lead to his death, the death of his love, and the deaths of his family.Light asks Penber if he's carrying a laptop, and if he has a file containing the names of all of the FBI agents in Japan. Penber says that he doesn't have a file like that, and Light hands him an envelope. He tells Penber to hold onto the envelope, take out the transmitter and put the earphones in. Over transmitter, Light leads Penber through a turnstile in the western entrance at 3:11 PM. Penber enters a train on the Yamanote Line at 3:13 and takes a seat. Light asks how many FBI agents there are, and Penber says that he thinks there are four groups, totaling twelve agents. Light says to call an agent that is ranked lower than him and ask for the names and faces of all agents sent to Japan. Penber uses his cell phone and calls an agent, and then asks him for the name and faces of the agents. Penber receives the FBI file at 3:21 PM, and Penber is the second FBI agent that receives it. Light tells Penber to take the contents out of the folder he gave him, and Penber takes out four envelopes with ten rectangular spaces cut out of the left side of each one. Light says to write down the names of the agents into the blocks on the folders. At 4:42 PM, when Raye exits the train, he dies of a heart attack while turning around and seeing Light. Light takes the files home and takes the pages of the Death Note out of their envelopes, revealing the times and causes of death for each agent. Each agent will receive the file and die at a different time.After the sudden death of Raye, Naomi Misora decides to take part in the Kira case herself. Having been told by Raye that he showed his FBI badge to someone during a bus-jacking, Naomi deduces that Kira must have been on the bus. In her attempts to contact the Japanese Task Force, she comes across Light Yagami. Light uses his father's status to his advantage, telling Naomi that he is Chief Yagami's son, which allows him to slowly win her trust. Cautious at first, she uses the false name Shoko Maki in order to protect herself until she can reach L.After he realizes that this was an alias from the way Ryuk laughed, Light finally gets Naomi to reveal her name by saying that he is a member of the Task Force and is actually working with L. Taking advantage of Naomi's emotional state, Light gives the possibility that she could join the Task Force and help catch her fiancé's murderer. Light says that he will need to see a form of identification before she can join, and Naomi shows him her driver's license. Using a piece of the Death Note, Light writes down Naomi's name, resulting in her death by suicide. Her body is never found due to the specifications made by Light in the Death Note. Surveillance Cameras As Light arrives home, he finds the doorknob of his bedroom (which is usually lowered by a few millimeters) is strangely at the very top, plus the pencil lead placed on his door hinge is broken. Not only that, but his bluff, a piece of paper, was strangely put back in his door. This has Light believing that L has installed surveillance cameras and wiretaps within his room. Light then bribes Ryuk with apples, asking him to find where the surveillance cameras are. Light reveals he has hidden scandalous magazines and proceeds to browse through them in order to give off the impression to L that he is a normal teenager, and that the magazines were what he was hiding all along. During dinner, L has a message appear on TV, stating that the ICPO has dispatched 1500 investigators to Japan to investigate Kira, but Light sees through this bluff. When Light is about to study for his upcoming entrance exams, he has placed a snippet of the notebook and a mini-LCD TV within a potato chip bag (which contains a flavor which only he out of the rest of his family prefers). While studying, whenever Light places his hand in the potato chip bag, he actually checks for criminals' names using the mini-TV then writes down their names. The main idea is that L would see that criminals have died which Light could not have possibly see, being busy in his room, studying. With this trick, Light manages to kill two petty criminals. For the next few days, Light proceeds to kill more criminals, petty or not, in order to cover up the fact that petty criminals have died solely while he was studying. Eventually, the surveillance cameras get removed and Light plans on finding L through his father.Meeting L Light performs his entrance exams, when he notices a student sitting strangely on his seat. He passes the exams, scoring perfectly, and is able to become a student of To-Oh University. Alongside another student who scored perfectly, who was the student sitting oddly earlier, he gives a speech. Noticing the strange behavior of this student, who named himself after the famous pop idol, Hideki Ryuga, Light feels annoyed at his constant chattering that concerns Light's character."Hideki Ryuga" then reveals himself to Light as L. Light is shocked by this and is attempting to stay calm around this supposed new friend he's made. When Light arrives home, he throws a tantrum, and explains L's strategy, that should Light write down L's name using the alias even with the off-chance that it's real, the real Hideki Ryuga will die (since Light will have subconsciously pictured Ryuga's face), and suspicion will be pointed towards him. Not only that, but even if Light finds out L's real name, this L could very well be a proxy and suspicion from the hypothetical real L will be pointed towards Light again, as the timing will still be too convenient. Light accepts this challenge from L, getting excited over this upcoming battle of wits. L asks Light to play tennis with him, and they do so, nearly evenly matched. During the tennis game, both of them ponder strategies. Light comes to the conclusion that L asked him to play tennis in order to lay the groundwork for future meetings which will essentially be tests; Light also plans on confirming that Ryuga is L with confirmation from the Task Force. After Light wins the intense tennis match, L reveals that he is suspicious of Light being Kira, with Light still being forced to put up the act and pretends to be shocked. Light comes to the conclusion that, with this act, L is attempting to prevent Light from meeting with the Task Force. They hang out together at a cafe afterward. At the cafe, L tests Light multiple times, with Light managing to evade L's psychological traps. L asks Light to help the Kira investigation; if Light is Kira, then L will be closer to him and there is more room for Light slipping up, and if he isn't Kira, then his great intellectual ability will be of use to the investigation. Light takes advantage of this by demanding that he meet the Task Force members to confirm L's identity in order for him to begin helping the investigation. Much to Light's surprise, L accepts. Soichiro collapses due to stress, and both Light and L visit him at the hospital. There, through Soichiro, Light manages to confirm that the L who appeared before him is, in fact, the real L.The Second Kira On April 22, 2004 (2007 in anime), in a broadcast on Sakura TV, "Kira" sends tapes stating that if criminal reports stop, Kira will kill police officers and reporters, and then demands that the life of someone in charge of the Kira investigation be handed over—the Director's or L's. "Kira" says to choose one and reveal them in four days and that, because Kira knows the Director's face, there are no special requirements; however, if they should choose L, he must appear on Sakura TV and give a ten-minute speech. "Kira" says that they will decide if the person on the news is L, and if it is decided that he isn't, Kira will take the lives of several police officers as compensation. Light watches this broadcast, amused at the fact that someone else possesses a Death Note, likely with the Shinigami Eyes. Light figures this person is dangerous as they could tarnish Kira's reputation and their capture would be detrimental for Light, so Light figures he needs to join the Task Force in order to keep an eye on L as well as this fake Kira.A few days later, L asks Light to join the Task Force. Light arrives at the hotel and appears surprised at the small size of the Task Force, and L tells Light that there are a few outsiders who know what happens within the investigation and only one can contact L directly. Light thinks to himself that if everyone in the Task Force dies but one, the killer is revealed, so he must find out who the outsider with the information is. Light is told to look over the papers of the investigation and then watch the tape without taking notes or removing anything. After watching the tapes, Light says that there may be someone else with Kira's abilities, citing the difference in criminals killed, as well as the fact that some were killed immediately after revealing their faces. Light realizes that L would have told him his plan regardless of what he told L and that he set things up so that if Light didn't say there was another Kira, he would look suspicious, and if he did, he would help strengthen L's theory to the Task Force. L asks Light to help their case by pretending to be Kira and tells Light that only he is able to play this role, starting with writing a draft for the speech as Kira. Later, the tape is created and sent to various TV stations. The Second Kira responds with videos which contain indirect, and some rather direct, comments about Death Notes, Shinigami, and how they can meet. Light goes to Aoyama to find the Second Kira, but is unable to meet this Kira. However, due to having Shinigami Eyes, the Second Kira is able to identify Light as Kira because of her being unable to see Light's lifespan.After finding out his address, the Second Kira arrives at Light's house, and Light invites Misa to his room and asks her to explain her actions. Misa says that she wanted to meet Kira because her parents were murdered in front of her, and Kira killed the man who did it. Misa asks to be his girlfriend, admitting that she wouldn't even mind if he simply uses her. Light agrees, intending to kill her after she outlives her usefulness. However, Misa's Shinigami, Rem, promises to kill him if he ever harms Misa. Light finds Rem to be a massive threat, as having limited control over Misa would result in her doing something reckless, not to mention Misa's capture could result in Rem killing Light. Light has to now keep a gaggle of girlfriends so that his newfound relationship with Misa won't stand out, as L had already deduced that Kira and the second Kira have allied. Misa goes directly against Light orders and, instead of meeting two weeks after their first meeting as Light requested, Misa meets up with Light only two days following their first meeting. Light uses this opportunity to convince Rem to help him kill L, promising her that it's for Misa's happiness. Rem agrees to do so, and Light said that she must follow his command only when he tells her to. At campus, Light surprisingly meets up with L again, where L steals Misa's phone after taking advantage of a crowd. Misa is then taken away, with L revealing that he found DNA evidence in Misa's room pointing towards Misa being the second Kira. This is dangerous for Light, as Misa being the second Kira would point towards Light being the original Kira.Light, now cornered by L, puts his master plan into action. Rem had already relinquished ownership of Misa's notebook to Light, wiping her memories and preventing her from confessing. Light then swaps the notebooks with their respective Shinigami, with Ryuk being attached to the notebook originally owned by Misa and Rem attached to Light's. Light places two fake rules in the notebook Rem is attached to, one being that when the notebook is destroyed, anyone who has touched the notebook will die, and, most importantly, whoever doesn't write names within the notebook within 13 consecutive days dies. Light instructs Rem to allow Kyosuke Higuchi to become the new owner of the Death Note she is attached to, then asks L to detain him. During his confinement, no criminals die, which strengthens the case for Light being Kira. Within seven days of confinement, Light gives up his ownership of his notebook, and consequently has all of his memories of being Kira wiped and altered. During his fifteenth day of confinement, criminals begin dropping dead again, and on his 50th day, the Task Force has L release Light and Misa. Soichiro then fakes an execution by shooting Light and Misa with a blank gun, which convinces L to release Light and Misa from their confinement as Misa would have killed Soichiro in this situation. Yotsuba Light accepts L's offer to join the investigation team to hunt down Higuchi, who has taken up the mantle of Kira. During the investigation of Yotsuba, Light works under the alias "Light Asahi".L handcuffs him and Light together, displeasing Misa and Light. L suggests manipulating Misa in order to get information from her, but Light refuses, as he dares not to ever take advantage of someone's feelings. While Misa is resting in her hotel room, L acts lethargic about how catching Kira will be difficult, prompting Light to fight him. Months later, while L is sulking and not working on the case, Light finds a correlation between the killings and the growth of Yotsuba, having the investigation believe that Kira is either within Yotsuba or working behind Yotsuba, and also leads them to the conclusion that Kira can kill through means other than heart attacks. Keeping watch of the meetings held by the head of the Yotsuba members, Light objects to L letting the killings continue, and poses as L and decides to call Reiji Namikawa, who agreed to help L and postpone the killings. Misa eventually finds evidence pointing towards Kyosuke Higuchi being Kira. While L and the investigation team enacts the plan to take down Higuchi, Light keeps watch of the situation and follows L, eventually to the point where he is riding on a helicopter with L, and witnesses Higuchi's arrest. While the Task Force discovers the Death Note, Light touches it, regaining his memories as Kira once again. In order to claim ownership of the Death Note he is currently holding, Light kills Higuchi using a snippet of the notebook within his watch. L and the Task Force then find the 13-day rule, successfully clearing Light and Misa of being suspected, while L is still skeptical.
