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 death god. Any human whose name is written in the notebook dies, and Light has vowed to use the power of the Death Note to rid the world of evil. But will Light succeed in his noble goal, or will the Death Note turn him into the very thing he fights against?

Genshisuru Kami (Visions of a God)
A two hour episode of Death Note, mainly a compilation of the confrontations between Light and L, re-edited from Ryuk's perspective with new dialogue and soundtrack along with additional animation that could not be included in the original series. An Unnamed Shinigami comes to Ryuk to question him about his new story in the human world.
L o Tsugu Mono (L's Successors)
This story continues where the previous left off, continuing the story of Light. As the previous special told Light and L's battles, this story does the same with the conflicts between Light, Mello, and Near.
