Light Yagami is an ace student with great prospects - and he's bored out of his mind. But all that changes when he finds the Death Note, a notebook dropped by a rogue Shinigami, a death god. Any human whose name is written in the notebook dies, and now Light has vowed to use the power of the Death Note to rid the world of evil. But when criminals begin dropping dead, the authorities send the legendary detective L to track down the killer. With L hot on his heels, will Light lose sight of his noble goal... or his life?
Light thinks he's put an end to his troubles with the FBI—by using the Death Note to kill off the FBI agents working the case in Japan! But one of the agents has a fiancée who used to work in the Bureau, and now she's uncovered information that could lead to Light's capture. To make matters worse, L has emerged from the shadows to work directly with the task force headed by Light's father. With people pursuing him from every direction, will Light get caught in the conflux?
After a week locked up with no one but Ryuk for company, Light is ready to give up his Death Note and all memories of it. Freed from his past actions, Light is convinced he's innocent. But L is ready to keep Light under lock and key forever, especially since the killings stopped once Light was incarcerated. Then a new wave of Kira crimes hits Japan. Someone else has gotten their hands on a Death Note, and these new deaths aren't focused on making the world a better place, they're focused on making money. Big business can be murder, and Kira has gone corporate!
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?
