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.

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.

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.

Though Mikami has written all the investigators' names in the Death Note, a minute passes and everyone is still alive. Near seizes Mikami's Death Note, and all is at last revealed.
