Death Note

Average college student Light Yagami discovers a black notebook that claims to be able to kill anyone whose name and face is known to its owner. After testing the notebook on a bully and a criminal holding his father Soichiro Yagami hostage, Light is met by the notebook's original owner - a shinigami named Ryuk. After some persuasion by Ryuk, Light becomes compelled to use the notebook as a means to create a utopia and he eventually becomes known to the public as Kira. However, genius detective L tricks Light into revealing that Kira lives in Japan's Kanto region with a fake television broadcast. L also discovers that Kira is receiving information from the Japanese police, causing him to suspect them and their family members. At the end of the episode, Ryuk reveals to Light that he is being tailed by an FBI agent.

Ryuk who can see the lifespan of humans, reveals to Light that Misa Amane, a popular idol who Light is a fan of, may only have a few days to live. Light attempts to warn Misa after one of her concerts, but fails. However, one of her security guards, Tsutomu Yukida, overhears Light's warnings and offers to help Light protect Misa. Meanwhile, L meets with a few members of the Japanese police, one of which includes Soichiro, in order to form a task force dedicated to capturing Kira. Later, Light devises a plan to discover the name of the FBI agent following him after discovering that he can manipulate the actions of his victims before killing them with the notebook. Using a criminal to orchestrate a bus-jacking, Light tricks the agent into revealing his name; Raye Penber. He writes Raye's name in the notebook, detailing that Raye will shoot L once he reports to him. Later, Light receives a phone call from Yukida, only to discover that he will be the one to end Misa's life. After being knocked unconscious by Yukida, Misa wakes up to find him dead and the shinigami Rem leaving a red Death Note beside her. At the end of the episode, Light is accused of being Kira by L over the phone, who also reveals that Raye Penber was in fact an alias.

With "Raye Penber" still following him, Light realizes that L's phone call was in fact a trap. Light becomes determined to kill all the FBI agents involved in the Kira case in order to disperse suspicion on him. In the midst of his planning, Light remembers finding a picture of Cathy Campbell, the name of Raye's lover, during the bus-jacking incident. Meanwhile, Misa sacrifices half of her remaining lifespan to Rem in order to receive the shinigami eyes, allowing her to see the real names and lifespans of anyone she looks at. Since a human with the shinigami eyes cannot see the lifespans of someone who owns a Death Note, Misa is able to deduce that Light is Kira after spotting him at one of her concerts. Later, Light is able to blackmail Raye into writing the names of the other FBI agents into pages of the notebook by threatening to kill Cathy. However, Raye eventually sees through the plan and tricks Light into revealing himself to be Kira. Misa, who has been following Light without his knowledge, kills Raye by writing his real name, Mark Dwellton, into her notebook.

Suspecting that Mark Dwellton met with Kira before his death, L plants cameras and listening devices in the houses of families Mark was following. Light quickly realizes this and formulates a plan to temporarily prove his innocence to the task force members. However, L's suspicions do not waver and he enrolls into Light's university in order to investigate him personally. Meanwhile, Misa becomes determined to find Light, having become a Kira supporter since the day Light punished her parents' murderer. After leaving a televised message asking the police to cooperate with Kira, Misa finds Light in his house and rushes to his room, unaware that L's cameras are still in place.

Light manages to get Misa out of his house and the two meet at a park. There, Misa reveals that she has fallen in love with Light and wishes to help him kill L. At the same time, L reveals to the task force that, based on the killings made at the wake of the recent broadcast, a second Kira may have appeared. L then suggests recruiting Light into the investigation team both as a way to move the investigation further and get him to possibly reveal himself as Kira. Later, Rem reveals to Light that it was Gelus and not her who saved Misa from Yukida, explaining that a shinigami can die by extending a human's lifespan. L and Soichiro, meanwhile, investigate Yukida's death, discovering that he died of a heart attack- Kira's primary method of killing. This, coupled with a trail of evidence left behind by Misa, causes her to be arrested by the task force on the grounds of being the second Kira.

Rem decides to have Misa relinquish ownership of her notebook, causing her to lose all memories associated with the Death Note. Rem passes Misa's notebook to Light and demands that he save Misa. After devising a plan to prove his and Misa's innocence, Light buries Misa's notebook in a forest and tasks Rem with giving his original notebook to a greedy individual. Later, Light approaches L and the task force and requests to be placed under surveillance on the grounds that he could subconsciously be acting as Kira. After Light is incarcerated, the killing of criminals stops for some time, but they resume once Rem passes the notebook to a new owner. After he becomes sure of this, Light signals to Ryuk to relinquish ownership of his notebook, erasing his memories of being Kira. Later, L and Soichiro create a test for Light that allows him to prove both his and Misa's innocence. Meanwhile, Near, a mysterious protégé of L, contacts the task force and leads them to the conclusion that the current Kira is affiliated with the Yotsuba Corporation.

Light and Misa join forces with the task force in order to capture Kira. However, L's suspicions of the two do not waver as he suspects that they intentionally lost their memories by passing their powers to someone else. After realizing that they are under suspicion by the authorities, a group of Yotsuba executives enlist the aid of the investigator Babel, who is revealed to be Near in disguise. The efforts of Light, Misa and Near enable the task force to narrow down their suspicions to Yotsuba executive Kyosuke Higuchi. Using a fake television broadcast to lure him out, the task force is able to trap Higuchi and arrest him. Light regains his memories of being Kira and ownership after touching the notebook and killing Higuchi with a notebook scrap hidden inside his watch.

After the notebook is confiscated by the task force, a fake rule written by Ryuk convinces L that Light and Misa are innocent. With suspicion of being Kira cleared, Light asks Misa to uncover the red notebook from the forest he buried it in. Just as she is about to open the container it is sealed in, a thug named Hiroki Yudagawa attacks her and steals the container. The thug is eventually revealed to have been hired by Teru Mikami, a criminal prosecutor who has been following Misa after deducing her connection to Kira based on various news reports. After L exposes Yudagawa as the culprit, Light attempts to capture him but the thug manages to escape. After Kira's judgments continue again, Light considers the possibility of Yudagawa's associate being a Kira worshipper. Light, recalling a time when he met a prosecutor who professed his eagerness to help Kira, determines that Mikami is the new Kira. Light contacts Mikami directly and enlists his aid to dispose of L. Meanwhile, Near interrogates Yudagawa and discovers that he stole a notebook from Misa on behalf of a prosecutor. However, Yudagawa is killed by Mikami before he can reveal anything else. Later, L meets with Soichiro and reveals that Near is next in line to succeed L. He tells Soichiro to continue to watch Light as he has a plan to resolve the Kira case. The next day, Mikami and a team of prosecutors meet with the task force at their headquarters in an attempt to confiscate the black notebook. Light, meanwhile, meets with L in an abandoned warehouse. L, who has the black notebook in his hands, discusses the Kira investigation with the task force through a video camera. L then destroys the camera and attempts to convince Light to give up being Kira. As Light maintains his innocence, L begins writing Light's name into the notebook, forcing Light to wrestle the notebook away. Mikami, who is revealed to have the shinigami eyes, texts Light L's real name after seeing his face through L's camera. Light writes down "L. Lawliet" into the notebook but L does not die.

L reveals that he had tricked Light into writing into a fake notebook, thus; exposing the latter as Kira. After Light confesses to L, the rest of the task force enter the warehouse only to see L die from a heart attack, courtesy of Mikami. Since only L heard the confession, Light convinces the task force members that L gave Light his real name and wrote it down in an act of self-defense. After L's funeral, Near takes over L's duties as head of the task force and focuses the investigation on the prosecutors that came into the task force headquarters the day L died. Meanwhile, Light meets with Misa and Mikami at a rooftop and restores Misa's memories of being the second Kira by tying a scrap from the red notebook onto her wrist. Later, task force member Shoko Himura betrays her team and conspires with a mysterious group of men to kidnap Sayu, Light's sister. Himura and her associates demand that the task force hand over the black notebook in exchange for Sayu's life.

Light and the task force attempt to ambush Himura's group and rescue Sayu by pretending to exchange the notebook for her life. However, Mello, Near's ambitious alter-ego, awakens and takes over Near. Mello appears during the ambush and reveals himself to be the leader of Himura's group. Though Sayu is rescued, the notebook falls into Himura's possession. At the task force headquarters, Light discovers the name of one of the kidnappers, Mason Fujiyama, and uses him to reveal the real names of the other kidnappers. Light uses the information to plan a second ambush at Mello's hideout, leading to the latter's incarceration. However, Mello escapes from confinement before his real name can be exposed by Mikami. Later, Light uses Himura's real name, Halle Lidner, to manipulate her into returning the notebook to him. Soichiro, who has been keeping an eye on Light as per L's request, witnesses Light regaining the notebook. He confronts Light and after failing to convince him to give up the mantle of Kira, commits suicide by writing his own name in the notebook. Meanwhile, Lidner, influenced by the Death Note, carries out a suicide bombing at Mello's new hideout.

Mello survives the bombing and, over the phone, vows to expose Light as Kira. Light plans another ambush with the task force and Japanese police in order to defeat Mello. Later, Light meets with Misa and Mikami and orders them to kill the task force and Mello respectively. During the ambush, Light confronts Mello in a warehouse, who reverts to his Near personality. Near reveals that he pretended to be taken over by Mello as part of a plan to expose Mikami as the current Kira. Meanwhile, Mikami, who has also entered the warehouse, uses his shinigami eyes to write down Near's real name, Nate River, in his notebook. Once Light prematurely declares victory and Mikami's notebook is revealed to have been switched with a replica, they are both implicated as Kira. The task force and the police subsequently ambush Light and reveal that they were working with Near/Mello the entire time. Via a televised message recorded prior to his death, L reveals he orchestrated Sayu's kidnapping and accumulated more than enough evidence to prove Light is Kira. After Near and the task force reveal Soichiro sacrificed himself to raise suspicion on Light and Lidner was secretly an FBI agent planted by L, Light confesses to being Kira. Near, who has the real notebook in his possession, is attacked by Mikami, but is shot by police. Light uses the ensuing struggle as an opportunity to use his own notebook hidden underneath his clothes only to also be shot. In desperation, Mikami sets fire to the warehouse, unintentionally trapping Light in a circle of fire. As everyone evacuates the warehouse but Light, Mikami's real notebook burns, causing both Misa and Mikami to lose their memories of being Kira. As a result, Misa forgets that she was ordered to kill the task force. Meanwhile, Ryuk and Rem leave the human world after Light burns to death trying to reclaim the other notebook.
