Light Yagami

A genius high school student who discovers the Death Note, a supernatural notebook that grants the user the ability to kill anyone whose name and face they know. Bored by the mundane world and driven by a twisted sense of justice, Light adopts the alias "Kira" to purge the world of criminals and rule as a god. His character is defined by his sociopathic brilliance, Machiavellian manipulation tactics, and a chilling composure that allows him to outwit the world's greatest detectives.
