Picking up where the first one leaves off, Light joins the task force searching for Kira in an effort to avert suspicion from himself---and get rid of L.

The story begins on the heels of the first movie as Light Yagami joins the investigation team in pursuit of the serial killer known as "Kira." While L still strongly suspects that Light is "Kira," Light tries to uncover L's real name so he can kill him with his Death Note. Confusingly enough, a new rash of murders all around the world are taking place, with a "Second Kira" claiming responsibility. Light learns the identity of the Second Kira and suggests they join forces to get rid of L. Will L be able to catch "Kira" before he is killed?

In the second installment of the Death Note film franchise, Light Yagami meets a second Kira and faithful follower Misa Amane and her Shinigami named Rem. Light attempts to defeat L along with Teru Mikami (a Kira follower) and Kiyomi Takada (another Kira follower) but in the end will Light win? or will a Shinigami named Ryuk make all the difference in Light's victory or his ultimate death?—Laharl Krichevskoy

Misa receives a Death Note from Rem, another Shinigami. As Light joins the task force after Shiori's funeral, Misa becomes the Second Kira and forces a TV station to broadcast her taped messages. Misa, using her Shinigami Eyes, looks through the TV screen and kills a critic of Kira, as well as Detective Mogi and two policemen, who were trying to disperse a rally of Kira's supporters. Light's younger sister Sayu is almost killed, but Soichiro crashes into the festival wearing a motorcycle helmet, which prevents Misa from seeing his face. Light arrives to comfort Sayu and Soichiro, but is spotted by Misa, who correctly identifies Light as Kira. Misa approaches Light near his home, requesting to be his girlfriend and to join his mission to cleanse the world. Seeing that she has Shinigami Eyes, Light accepts her help, and sets up a meeting between her and L, in the hope of learning L's true name. However, Misa is arrested by L because of evidence connecting her to the taped messages. Fearing that Misa will confess, Light arranges for himself and Misa to forfeit their Death Notes, thereby losing their memory. Light buries his Death Note, while Rem gives the other Death Note to Takada, a reporter covering the Kira case. His plan is to sit in jail while Kira's killings are continued by Takada, thereby convincing the police of his innocence.

After some time, Light and Misa are released, but kept under surveillance by L. Light finds a clue leading to Takada, and assists the police-team in arresting her. As a result, the police learns of the existence of Death Notes and Shinigami. By touching the Death Note, Light regains his memories, and he proceeds to kill Takada using a fragment of a Death Note hidden inside his watch. Earlier, Light had written a fake rule into the Death Note stating that, once a person writes a name, he must keep writing names every thirteen days or perish. The police, believing this rule to be real, consider Light and Misa as being completely exonerated, as they were in custody for much longer than thirteen days.

Light asks Misa to uncover the buried Death Note to kill L. Misa, having forgotten L's name, resumes Kira's killing spree instead. L decides to send the task force, bar himself and Light, to America to test the authenticity of the 13 day rule. With suspicion falling upon Misa, Rem is forced to kill Watari and L to protect Misa from being arrested again. Since Shinigami are not allowed to protect humans, the action results in Rem's death. For the sake of halting the police-investigation into Kira, Light proceeds to write his own father's name into his Death Note, much to Misa's horror. Strangely, his father doesn't die, and Light is surrounded by the police at gunpoint. L also emerges, revealing that he wrote his own name into the Death Note, scheduling his death a month in advance and becoming immune to further writings in the Death Note. He also reveals that the Death Note Light wrote on was a decoy and that the task force did not leave for America but were surveilling Light from another location, thereby witnessing him reveal his true colors as Kira. Light, being cornered, pleads with Ryuk to kill the people surrounding him, but Ryuk decides to kill Light instead. He reveals to Light that any human who owns a Death Note is banned from Heaven and Hell, and will instead spend eternity as nothingness. Light dies in his father's arms, begging his father to believe that his actions were for the sake of justice. The police decided to cover up the truth, and to announce that Kira killed Light and then himself. Twenty days later, Soichiro meets L one last time before L peacefully dies. One year later, on Light's birthday, Soichiro maintains the false story to his wife and Sayu, that Kira killed Light. Misa also celebrates Light's birthday, loving him but having no recollection of the Death Note. The film ends with Ryuk flying around the Tokyo Tower and laughing.
