Part I

ARC undefined Part I is the first part of the Death Note anime and manga series. This part primarily focuses on a cat-and-mouse battle of wits between Kira, who is 17-year old Light Yagami, and L, an eccentric detective seeking to catch Kira.

During interviews, Tsugumi Ohba and Takeshi Obata refer to this part as the "L arc." Many readers and viewers also use this name.

Chapters 1-22 (Revelations arc)
Light Yagami is a bored high school student, and Ryuk is a Shinigami bored of the monotonous world of the Shinigami Realm who drops his Death Note into the Human World. Light picks it up and decides to use it make the world a safe utopia while he becomes god of this new world. He adopts the name "Kira", given to him by the first people to notice that someone is passing judgment on criminals.

The killings catch the attention of the ICPO and L, who challenges Light, bent on discovering his identity. Light, accepting this challenge, begins to test the limits of the Death Note while throwing the police off of their case and breaking the cooperation between them and L.

After Light kills all of the FBI agents sent to Japan to assist L, he becomes L's primary suspect. L enrolls in To-Oh University to catch Light off guard and asks Light to join the investigation team, helping them both reach their goals of uncovering the other's identity.

Chapters 23-33 (Second Kira arc)
Sakura TV broadcasts tapes from Kira. L deduces there is a second Kira and Light understands their message to mean that they have the Shinigami Eyes. After Soichiro receives the tapes, L asks Light to join the Task Force, not only in the hopes that he will help them catch the second Kira, but also to keep a closer eye on Light. Light plans to meet the second Kira before L and before the second Kira blunders and causes trouble for him.

After the second Kira's diary tells Light to go to Aoyama, a girl named Misa Amane visits his house, revealing her Shinigami, Rem, and asking to become helpful to Kira. Light realizes he will have to keep Misa around to keep her from causing trouble for him, and because Rem will kill him if anything happens to her, he also has to keep Misa safe from L.

Since L has already deduced that Kira and the second Kira are working together, Light dates multiple girls at once to explain his connection to Misa. However, L finds physical evidence pointing to Misa being the second Kira, and she is arrested and tortured for information. Light also asks to be detained and adds a fake rule to the Death Note, stating that whoever writes in the notebook must add names within 13 days or die. He wipes his and Misa's memories of being Kira and relinquishes ownership of the Death Note.

Chapters 34-59 (Yotsuba arc)
After fifty days of confinement in which the murders continued, L releases Light and Misa. After staging an execution, they are confirmed to not be Kira, and Light now wants to catch the new Kira alongside L. Light deduces that Kira is a person within the Yotsuba company, and L calls for assistance from old acquaintances Aiber and Wedy. L is still doubtful Light is not Kira, so he handcuffs himself to Light to keep a close eye on him.

Matsuda ruins their plan by entering the Yotsuba building and getting caught by the company executives. He obtains proof of their connection to Kira and suggests they hire Misa as a model before escaping by faking his death. The executives hire detective Eraldo Coil to look into L, and Aiber, playing the role, gains more information about them.

During her interview with the executives, Misa is contacted by Rem, and she regains her memories of being the second Kira. Rem tells her who the Yotsuba Kira is, and Misa gets Kyosuke Higuchi to confess. L uses Matsuda as bait to make Higuchi show them his method of killing, and with the help of the police force, the Task Force corners and detains him.

The Task Force learns of the Death Note, and Light regains his memories and continues his work as Kira, now with a very strong alibi and a close connection to L. He puts Misa in a situation where she is in danger, and Rem, knowing that she is being manipulated, kills L and Watari, leaving Light victorious with the Death Note she leaves behind.
