Light Yagami.

About Light Yagami

Light Yagami is the main protagonist of the manga series Death Note, created by Tsugumi Ohba and Takeshi Obata. He is portrayed as a brilliant but bored genius who finds the Death Note, a supernatural notebook that allows the user to kill anyone by knowing their name and face, after it is dropped by the Shinigami Ryuk. With the power of the Death Note, Light eliminates those he deems morally unworthy of life, masterminding a worldwide massacre as the mass murderer Kira (キラ). He claims that he is making the world a better place by purging it of all its crime and impurities, taking the stance of the "God of the new world" and thus fulfilling his goal, although his massacre involved a significant amount of innocent civilians or law officers. Over the course of his efforts to create a world free of crime, wherein he would rule as a godlike figure, Yagami is pursued by law enforcement groups such as the NPA and a world-renowned detective named L.
