Brilliant but bored high school student Light Yagami suddenly finds himself holding the power of life and death in his hands—the power of the Death Note. He decides to rid the world of evil—by killing off criminals one by one. When the murders start to pile up, genius detective L is on the case, and an epic battle of wits unfolds.

While the world’s criminals continue to drop dead, L meets by computer with representatives from various nations. He requests that a task force be set up in Japan, under the direction of none other than Soichiro Yagami, Light’s father.

Ryuk, the Shinigami, or god of death, who dropped the Death Note into the human world, warns Light that someone is on his trail. Light is troubled that he can’t find out the identity of his tracker, and Ryuk suggests an amazing deal...

Light—now known to the world as Kira—tests the Death Note to understand the scope of its powers by killing off six convicts in various ways—and confirms he can control his victims’ actions before they die.

Soichiro Yagami demands to meet with L in person when he finds out that L has secretly brought FBI agents into Japan. Light, meanwhile, has found a way to get those very FBI agents off the case—permanently...

Light meets a woman at the Police Department with an urgent message for the Kira task force. As son of the chief investigator, Light listens to her story, and is startled to discover she may have information that could lead to his arrest.

Light uses the Death Note to try to get rid of the woman who could get him captured, and is shocked when it doesn’t work. Realizing she must have given him an alias, he’s only got minutes to find out her real name before she tells her story to the task force.

L insists on setting up bugs and cameras in the homes of Chief Yagami and Deputy Director Kitamura—whom Raye Penber was tracking. But Light is a step ahead as usual—he knows he’s being watched.

The murders continue, and L grows suspicious of Light’s too-perfect behavior and decides to investigate him on his own. In order to get closer to Light, L enrolls at the same university and reveals himself to be L.

L's suspicion of Light deepens, compelling him to invite Light into the investigation. But then a phone call alerts them that Soichiro Yagami has suffered a heart attack!

As predicted on the tapes sent to Sakura TV, news anchors and commentators who expressed doubt about Kira die one by one. On further investigation, L concludes that this Kira is not the original—there's a second Kira!

With a second Kira now on the loose, L asks Light to join the task force and pose as the real Kira in order to catch the copycat. Light agrees, hoping to divert suspicion from himself. To his surprise, this new Kira has a special ability even Light lacks…

Light goes to Aoyama to discover the identity of the second Kira before L becomes more suspicious. But Misa Amane, the new Kira, uses her unusual gift to find Light before he finds her.

Light and Misa show each other their Death Notes, and Light asks Misa to have her shinigami Rem get rid of L. But Misa asks something of Light in return—to fall in love with her!

Evidence turns up that points to Misa Amane as the second Kira. In an effort to spare her, Rem forces Misa to forfeit her ownership of the Death Note.

Misa is in confinement, though her memories of the Death Note have been completely wiped away. When Light is confined as well, the murders stop and suspicion of Light grows stronger. Then suddenly, the killings resume.

After fifty days of confinement the killings continue, and Misa and Light are released. But L has devised a plan to ensure no more murders occur, and has Light's father, Soichiro, take the two for a ride that may be their last.

Though L is still suspicious, Light and Misa, their memories of being Kira wiped clean, return to headquarters, where Light notices a strange connection between the recent Kira killings and the Yotsuba Group.

Matsuda, the task force member assigned to watch Misa, is eager to distinguish himself, and while on a job with Misa, he decides to do a little snooping on his own at the Yotsuba Group’s Tokyo headquarters.

L's team discovers that the Yotsuba Group meet in secret to discuss the elimination of individuals who are troublesome to their company, and concludes that Kira must be one of the eight executives. Can Light posing as L ferret out the right one?

The Task Force uses Misa as a way to get closer to the Yotsuba corporation. But things get complicated when Rem tries to communicate with her.

Thanks to Misa, the Task Force now knows the identity of the new Kira and L plans an elaborate scheme to smoke him out of hiding.

L, Light and Misa watch from the investigation team building and wonder who he is talking to. L wonders if Higuchi is talking to a shinigami. Rem convinces Higuchi to go to the station, but she has her own selfish motives for doing so.

While Higuchi is finally captured, Light inadvertently regains his memories as Kira.

Light, his memory recovered, orders Misa to begin killing after Higuchi dies. The Shinigami Rem realizes that everything is going according to Light's plan, and that L will arrest Misa as Kira-unless Rem acts quickly.
