Death Note

Death Note is a manga series created by writer Tsugumi Ohba and manga artist Takeshi Obata. The main character is Light Yagami, a high school student who discovers a supernatural notebook, the "Death Note", dropped on Earth by a death god named Ryuk. It centers around Light's attempt to create and rule a world cleansed of evil using the notebook and the efforts of a detective known as L, and subsequently his successors, Near and Mello, to stop him. The Death Note grants its user the ability to kill anyone whose name they know, by writing the name in the notebook while picturing their face.
