Light Yagami
In Tokyo, a disaffected high-school student named Light Yagami finds the "Death Note", a mysterious black notebook which can kill anyone as long as the user knows both the target's name and face. Initially terrified of its god-like power, Light considers the possibilities of the Death Note's abilities and kills high-profile Japanese criminals, then targeting international criminals. Five days after discovering the notebook, Light is visited by Ryuk, a "Shinigami" and the Death Note's previous owner. Ryuk, invisible to anyone who has not touched the notebook, reveals that he dropped the notebook into the human world out of boredom and is amused by Light's actions.
