Light Yagami is a brilliant high school student with a strong sense of justice. Disillusioned with the corrupt world, he finds the Death Note, a notebook that can kill anyone whose name is written in it. Using the alias "Kira," he aims to create a crime-free utopia. Light is strategic, manipulative, and increasingly ruthless, believing he's the only one who can deliver true justice. His main adversary is the detective "L," leading to a tense, high-stakes battle of wits.
