Appearance.
Light is a young man, standing at above average height with light-brown hair and brown eyes. 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. If not wearing a similar style of clothes, he is seen wearing a suit. He is considered to be quite handsome.
Light has medium-length brown hair with bangs and hazel eyes. Other Yagami traits include chiseled features, flawless fair skin, and an infectious, charismatic smile. He is always neatly dressed. Light prefers formal and understated clothing, emphasizing his discipline.

Light is introduced as a teenager with exceptional intellectual abilities, a calculating and cunning man. However, after receiving the notebook, Light Yagami decided to become God and create a new world without criminals. He partially succeeded, but he didn't realize that by killing other criminals, he himself was becoming one. He is moderately sociable, but has no permanent friends or girlfriends. He is uninterested in the activities of his peers, constantly being alone with his hobbies. Since childhood, Light hated crime and was guided by a sense of justice in his actions, but he did not show his innocence unless necessary.
Yagami possesses a sharp, tenacious mind and analytical thinking. He is skilled at cunning, lying, and manipulating, often using people as puppets because he sees no one as his equal.
On the outside, Yagami appears emotionless and calm. In reality, he suffers from delusions of grandeur, hypocrisy, sudden emotional outbursts, and clearly feigned psychosis. He is cruel, apathetic, and adventurous by nature. Driven by emotions and psychological problems, he makes serious mistakes, creates dangerous situations, and fails to understand the consequences of his actions.
However, despite all his crimes, Light will never become the embodiment of pure evil. He sincerely loves his father and sister and will never stop caring for them. Thus, humanity and compassion will forever remain within him.

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.

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 2006, 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.

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.

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.

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.

On April 22, 2007, 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.

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.

Light instructs Misa to find her buried Death Note, which results in her regaining her memories. Light instructs Misa to kill L if she remembers his real name from when they were on campus, but Misa doesn't remember and so makes the Shinigami Eye deal again, which is what Light wanted in case Misa forgot L's name, as taking the Eye deal and halving her lifespan would pressure Rem. Light then instructs Misa to begin killing criminals again so that L would suspect Misa is behind the killings. This is in order to put Rem in a situation where she'd be forced to kill L in order to save Misa. Rem does indeed kill L and Watari, which results in her death, just as Light planned.
After winning the battle with L and taking his persona, Light gains control of the Kira investigation team. This puts him on the safest ground as his role as a second generation L, covering his identity as Kira.
For the next five years, by using L's database of criminal records, Light's judgments have become fiercer than ever. As a result, the world falls into a dark age in which essentially everyone now lives under the law of Kira. At the same time, Kira's support grows exponentially, and even entire nations proclaim their support for Kira. By the time the second arc begins, Kira has garnered the majority of the world's favor.

After five years (2012) of everything going swimmingly, Takimura, the head of the NPA, gets kidnapped in exchange for the Death Note. At the same time, an FBI agent, John McEnroe, confronts Soichiro, and asks for the Death Note. This FBI agent also seeks cooperation from the Task Force to rescue Takimura from the kidnappers.
Light feels obligated to get rid of the kidnappers as well as the American organization as soon as possible, as they are currently the only people besides the Task Force who know of the existence of the Death Note. Light kills Takimura so that they no longer have a bargaining chip to trade the Death Note for, and it wouldn't look suspicious as one could easily assume the kidnappers killed him. However, the kidnappers then announce that they have kidnapped Sayu Yagami, which puts Light under pressure. In order to get help, he contacts the organization which John McEnroe offered to have them to talk to, and Light talks to Near for the first time, who introduces himself as N and is aware of the previous L's death.
Light tells Near the current situation and Near surveils the site of the trade using satellites. The exchange goes through, with the kidnappers gaining the notebook.
Near decides that he should chase the kidnappers on his own, only for his plan to fail as Mello uses the Death Note to wipe out more than half his team. Light takes advantage of this incident to trade all that he knows about the notebook for information on the perpetrator of the kidnappings. Near tells Light that someone using the nickname Mello, who is using the Mafia, is behind the kidnappings, and Light has the Task Force investigate Wammy's House, informing Light of Mello's motives.

The president calls Light, and Light figures out that Mello had blackmailed him. So, Light takes advantage of this to have the president organize a raid led by Yitzak Ghazanin. Light learns the location of Mello and the Mafia by taking control of the current Death Note owner and having him mail him their location. However, the raid fails thanks to the intervention of Sidoh, a Shinigami working with the Mafia.
Light then has Misa send a message to the Task Force as Kira, that Kira relinquished ownership of his Death Note to one of the members of the Task Force in order to attack the Mafia and regain the notebook. Light had expected Matsuda to gain ownership and make the Shinigami Eye deal, but, unfortunately for Light, Soichiro does so instead. The raid commences and they regain the Death Note, and Light tells them to confront Mello. Soichiro threatens Mello rather than killing him, giving Jose the opportunity to shoot Soichiro severely.
Mello then blows up the base and escapes, but Soichiro manages to give out Mello's real name to Light. Soichiro then dies in the hospital, after seeing that Light's lifespan was not absent, proving to him that Light was not Kira.
Along with Soichiro, Misa dies, whose name Light wrote down in the notebook, initiating suicide. Light considered her no longer needed.

Light selects Demegawa as the Kira spokesperson, intending to spread Kira's word in order to gain more power to take down Near and Mello. Thanks in part to David Hoope's death and the battle with the Mafia, the United States submits to Kira and dissolves the SPK, the organization Near is running. Near, deducing that the second L is Kira, calls Light and claims that he has interrogated Mello, and that he learned that there are fake rules. Near disproves the 13-day rule, and gives pieces of evidence to the Task Force pointing towards the second L being Kira, instilling some doubt within the Task Force in an effort to turn them against the second L.
Mello contacts Mogi and tells him to follow Mello to New York, which Mogi does so under the supervision of Light and the Task Force. However, Mello has Mogi go to the SPK's headquarters, which puts Light under extreme pressure as Mello and Near are constantly pressuring Mogi into spilling information. On one hand, if Light lets Mogi live, he might spill information that would be detrimental for Light, but if Light kills him, it'd only incriminate him.
Luckily for Light, Mogi doesn't give away any information. However, as he can't guarantee that, and in order to kill off Near and Mogi, Light sends Demegawa and tons of other Kira followers to attack Near. However, Near uses L's inheritance to distract the crowd and escape.
Near lies to the Task Force, claiming Mogi had died of a heart attack. This stirs suspicion against Light, which results in Aizawa giving Near lots of information, which has him believing that Light Yagami is the second L and Kira, while Mogi returns to the Task Force. Light now expects tighter surveillance now that Near turned the Task Force against him, so he has Misa relinquish ownership of her notebook to Teru Mikami, who kills Demegawa for running amok, testifying his worth. Mikami then selects Kiyomi Takada as the new Kira spokesperson, who coincidentally had a past relationship with Light.

Light takes advantage of this to use Takada to talk to Mikami. He does this while satisfying the Task Force, under the guise that he is investigating her. As a result, the Task Force relocates their investigation back to Japan, with the SPK eventually following suit. During a meeting between Light and Takada, Mikami calls them, and Light manages to confirm to Mikami that Light is Kira, and Mikami confirms to Light that Mikami is the new Kira proxy via subtle communication. Light then says that all the Task Force's surveillance cameras and most of the wiretaps must be removed as per Kira's request. Light then privately reveals to Takada that he is Kira.
For the rest of his meetings with Takada, Light and her communicated by writing notes as the Task Force placed a wire on Light. Light instructs Takada to tell Mikami to forge a fake notebook and use that fake to write down names in public, while he sends Takada the real names so she can do the killings. Light's incentive is that, for his final confrontation with Near, he expects Near to swap his notebook with a fake, which is why he's already preparing a fake. Light also has Mikami say things in public, suggesting Ryuk hasn't been following him. This way, when Near touches the Death Note, he won't think that there is no Shinigami because the notebook is fake. Light's plan goes perfectly, with Near's agent, Stephen Gevanni, having swapped the pages of Mikami's fake notebook.

After Near relocates to Japan, he will call Light under the pretense of cooperating in the investigation, while subtly making it clear that he knows who Light truly is and intends to challenge him. Later, after Gevanni acquires the fake Death Note, Near will contact the Task Force and arrange a final meeting between the SPK and the Task Force at the Yellow Box Warehouse. Light will eagerly anticipate this meeting, believing it will be the day he eliminates all of his enemies and finally begins creating his perfect new world. However, only a few days before the meeting, Takada will suddenly be kidnapped by Mello. To prevent any evidence from exposing Kira, Takada will kill Mello, while Light will use a piece of the Death Note to kill Takada as well before setting a fire to destroy all evidence. Two days later, the meeting at the warehouse will begin. Mikami will arrive carrying what Light believes is the real Death Note. Following Light's plan, Mikami will write down the names of everyone present except Kira's. Confident that everything has gone according to plan, Light will believe victory is finally his.
Instead, Near will reveal that the notebook Mikami brought is only a fake. He will explain that after Takada's kidnapping, Mikami acted on his own and wrote Takada's name in the real Death Note, unaware that Light had already done the same. Because of this unexpected action, Gevanni will be able to locate the genuine notebook and replace it with a fake, completely overturning Light's plan. After being exposed as Kira, Light will desperately deny the accusations. However, his own words, his behavior, and the evidence presented by Near will convince everyone that he is indeed Kira. Realizing he can no longer hide the truth, Light will laugh maniacally and openly declare that he wanted to become the god of a new world. He will insist that his actions were justified because he intended to create a peaceful society free of crime.

Near will calmly reject Light's argument, stating that no one has the right to decide justice for everyone else. He will call Kira nothing more than a mass murderer who forced his personal vision of justice upon the world. Looking around the room, Light will search for support but will instead be met with cold, disappointed expressions from the members of the Task Force, making it clear that none of them accepts his new world. As a last attempt to escape, Light will claim that the Death Note in the Task Force's possession might also be fake. While distracting everyone with his speech, he will secretly open the hidden compartment in his watch and attempt to write Near's name on the concealed piece of the Death Note.
Before he can finish writing, Matsuda will shoot him, interrupting his attempt. Furious over everything Light has done—including the death of his own father—Matsuda will continue firing, leaving Light gravely wounded. The others will stop Matsuda before he kills Light outright and will confiscate the hidden piece of the Death Note. Seeing Light lying wounded, Mikami will lose all hope and commit suicide by repeatedly stabbing himself with his pen, creating chaos inside the warehouse. Taking advantage of the confusion, the severely injured Light will gather the last of his strength and escape from the warehouse.
Near will tell Aizawa, Mogi, Ide, and Matsuda that there is no need to pursue him, believing that no hidden pieces of the Death Note remain and that Light's injuries will prevent him from getting far. Nevertheless, Aizawa will refuse to give up and will lead the others in pursuit. Light will eventually collapse inside another abandoned warehouse. There, Ryuk will approach him and remind him of the promise he made at the very beginning: when everything is over, he will be the one to write Light's name in his own Death Note. As Light quietly dies, he will see an apparition of L standing before him, mirroring the moment after L's own death. Shortly

Misa Amane is an aspiring model and supporter of Kira, who eventually becomes the second Kira. After receiving the Death Note, she seeks out Kira to thank him for killing the man who attacked her family and to offer him her help. After purchasing Shinigami Eyes, Misa learns that Kira's true identity is Light Yagami. After meeting Light, she decides to dedicate her life to helping him.

Appearance:
Misa is a short, slender, and attractive woman. Her eyes are primarily pale brown; however, they sometimes appear green, blue, or pink due to her frequent use of contact lenses. Her eyes turn bright red when she uses her Shinigami Eyes. She originally had light brown hair, but after becoming a model and actress, she dyed it blonde. She wears two small pigtails on the sides of her head. Misa often dresses in gothic and punk styles.

Personality:
Misa Amane is a cheerful, emotional, and very sociable girl, accustomed to openly expressing her feelings. She is energetic, impulsive, and often acts on impulse, without considering the consequences. Despite her apparent frivolity and naivety, Misa is capable of determination, courage, and perseverance, especially when it comes to those dear to her. She is boundlessly devoted to Light Yagami, willing to make any sacrifice for him, and has repeatedly risked her own life and memories. Misa loves being the center of attention and has a flirtatious and playful demeanor, but behind her bright image lies an emotionally vulnerable girl who suffered greatly from the death of her parents. She sincerely believes that Kira makes the world a better place, and therefore supports him not only out of love for Light, but also out of her own convictions. Misa sometimes displays jealousy, stubbornness, and childish spontaneity, but remains kind, caring, and capable of genuinely caring for those close to her.

Ryuk is a Shinigami who threw the Death Note into the human world for fun after becoming bored.

Appearance: He is very thin, with light gray, almost blue skin, spiky black hair, thin gray-blue lips, and sharp teeth. His limbs are abnormally long. He has large, round yellow eyes with bright red irises and wings on his back that he can retract. Ryuk is considered quite handsome in the world of the Death Gods. He wears tight-fitting black leather clothing, the collar and sleeves of which are trimmed with the fur of an unknown beast from the Underworld. He has a weakness for various skulls, crosses, and iron chains. A special cross-shaped decoration for the Death Note can be seen on his belt. This is why Ryuk always carries the note with him. He loves chunky rings. A silver earring with a heart at the end can be seen in his left ear. Ryuk also has black wings, which he uses for flight.

Personality/Backstory:
Ryuk dislikes boredom; he seeks entertainment. The Shinigami world has long since become a desert, inhabited only by those Death Gods who don't want to die and don't know why they live. They spend their days playing cards or simply lazing around. Ryuk grew tired of this pastime and decided to have some fun: he tricked Big Boss, took the second Death Note, and dropped it into the human world. This notebook was found by Light. Shinigami enjoyed watching Light Yagami's activities; he never interfered with him or helped him write names in the Notebook. Although he sometimes provoked him for fun. The path of entertainment is this god's principle; he doesn't care what happens in the human world, as long as it's interesting, fun, and funny. Often, he informs Light about certain aspects of the Death Note at the very last minute; it's interesting to see how he handles it. Although sometimes, he helped Yagami for his own interests, since apples are his weakness. Ryuk, like a human, succumbed to his weaknesses—apples.

Rem is the god of death. It was from her that Misa Amane received her Death Note. Like Ryuk, Rem possesses two Death Notes, but unlike him, she obtained hers by chance.

Appearance:
Rem has a very thin build, with a very long spine visible. She has distinctive features, such as her hair and the blue markings on her face. The only exception is in the anime, where her markings are purple. She has a raspy, slightly masculine voice. Height from 2.5 to 3 meters.

Personality:
While Ryuk amuses himself in the human world, Rem does the exact opposite. She views most people with disdain. Furthermore, while Ryuk remains indifferent to Light Yagami's success or failure, Rem actively assists Misa. She is even willing to sacrifice her life to protect her, as evidenced by her threat to Light. For Misa's sake, she aided Light in his plans.

Backstory:
The god of death, Jealous, who fell in love with Misa Amane, intentionally extended her life by writing the name of the person who would kill her in his Death Note. However, death gods are forbidden from artificially extending human lifespans. Having violated this law, Jelos immediately turned into a pile of ash. Touched by his sacrifice, Rem decided to give Jelos's Death Note to Misa. Rem is almost the complete opposite of Ryuk, who enjoys everything in the human world. She is contemptuous of humanity, believing her race to be superior. Ultimately, Rem becomes attached to Misa and tries to protect her from Light, whom she sincerely despises.

She died saving Misa.

Shinigami are gods of death who inhabit the Shinigami Realm, a desolate, lifeless place where they spend eternity. Their primary duty is to prolong their own lives by writing people's names in Death Notes. When a person dies from writing in the Note, their remaining lifespan is transferred to the Shinigami.
Shinigami Realm The Shinigami Realm is a gray, barren wasteland with ruined buildings. Most Shinigami spend their time idle, gambling, or observing the human world. Despite the existence of the Shinigami King, there is little strict oversight over them.

Basic Rules:

1. Each Shinigami possesses their own Death Note.
2. A Shinigami may intentionally drop their Death Note in the human world.
3. While a human possesses a Death Note, its original Shinigami owner usually follows them.
4. Shinigami are not supposed to selflessly save people. If a Shinigami intentionally extends a person's life at the cost of their own Death Note, they die, turning to dust.
5. Shinigami see a person's true name and their remaining lifespan.
6. Dealing with the Eyes of a Shinigami: The owner of the Death Note can make a deal with the Shinigami accompanying them. In exchange for half of their remaining lifespan, the person receives the Eyes of the Shinigami—the ability to see the true name and remaining lifespan of any person by looking at their face.

Known Shinigami:
Ryuk — a curious Shinigami who dropped his Death Note into the human world for fun;
Rem — a Shinigami who genuinely cares for Misa Amane;
Jealous — a Shinigami who sacrificed himself to save Misa;
Sidoh — the owner of the Death Note, which accidentally ended up in Light's possession;
Armonia Justin Beyondormason — a high-ranking Shinigami;
The Shinigami King — the ruler of the Shinigami World and the guardian of its laws.

A Death Note is a weapon capable of killing people from a distance. The user's location is irrelevant, but they must know the victim's name and face. A Death Note is an item originally belonging to the Death Gods. Using Death Notes, the Death Gods fulfill their primary purpose—killing people. The origin of these artifacts is unknown, but Death Gods are given Death Notes by the Death King. Each Death God can only be given one Death Note by the King, but a Death God can possess as many as they can get their hands on.

The notebook is an ordinary, unremarkable notebook with white, broadly lined pages. It has a black cover with the words "Death Note" written in white on the front.

Terms of Use:

1. The person whose name is written in the Death Note will die.
2. The Death Note will only work if the writer knows the person's face. Therefore, people with the same name will not die at the same time.
3. If the cause of death is written within 40 seconds of writing the name, the person will die that way.
4. If the cause of death is not written, the person will die of a heart attack after 40 seconds.
5. After writing the cause of death, there is an additional 6 minutes and 40 seconds to write down the circumstances of death.
6. The circumstances of death must be physically possible. If they are impossible, only the possible part will work, or the person will die of a heart attack.
7. A name cannot be "undone." Once a name is written, death is already inevitable, even if the entry is later erased.
8. A torn page or even a small fragment of the Death Note has the same properties as the entire Death Note.
9. A person who voluntarily relinquishes ownership of the Death Note loses all memories associated with it. Touching the Death Note again returns the memory.
10. A person who has used the Death Note will not enter either Heaven or Hell.
