In a world where justice seems unattainable, a prodigious student named Light Yagami discovers a mysterious notebook that belongs to a shinigami, a god of death. The only rule: if you write someone's name in it, that person will die. Surprised by the power he holds in his hands, Light decides to take control of humanity's fate. Convinced that he is destined to eradicate evil, he begins eliminating criminals and those he deems unworthy of life, transforming into a vigilante feared by many and adored by others.
However, his actions do not go unnoticed. The police, unable to find the perpetrator of these sudden deaths, seek the help of the enigmatic and brilliant detective known as "L." This peculiar investigator becomes a constant obstacle for Light, challenging his intelligence and raising the hunt for the criminal to unprecedented levels of tension and suspense. As both brilliant minds play their deadly chess match, Light begins to realize that absolute power brings unexpected adversities.
Amidst deception, manipulation, and moral dilemmas, the story explores how far one would be willing to go for justice and the price one must pay to become a god. Accompanied by unexpected twists and a haunting atmosphere, the narrative transforms into a fascinating reflection on morality and the consequences of playing with life and death.
