Light--working as Kira, the newest member of the NPA intelligence bureau, and L--has nearly succeeded in creating his ideal world. But the years of uncontested victory have made him complacent, and he is unprepared for a new attack close to home. With his younger sister Sayu kidnapped and the NPA's Death Note demanded as ransom, Light must travel across the world and confront two new adversaries, each with a very different agenda. Will Light's quick wits be a match for this new challenge, or will he be forced to choose between Kira's ambitions and his own family's lives?
Light Yagami is the top high school student of Japan who had, until recently, led a boring and uneventful life. That changed quickly when he found a mysterious notebook with the title "Death Note" on it, lying on the ground during the year 2003. Although initially skeptical, after realizing that the "Death Note" is a tool with the power to kill anyone whose name is written on its pages, Light decided to use it to "cleanse" the world of evil. Soon the many unexplainable deaths of reported criminals are noticed, and Light becomes hunted by the Japanese police force and a mysterious detective known as "L." L quickly discovers that the murderer, that the publics dubs "Kira," is located in Japan, and that he can kill just by knowing someone's face and name. Light realizes that L is just as cunning, if not more intelligent than himself, and begins a chase with L to see who will be the first to have his identity exposed.
