Death Note: Relight is a recap of the first 26 episodes of the series, focusing on the cat-and-mouse game between Light Yagami and detective L. The conflict begins when Ryuk, a Shinigami, loses his Death Note, which falls into Light's hands, a genius high school student who seeks to create a crime-free world using the notebook's power to kill anyone by writing their name. As Light, known as Kira, continues to carry out his own brand of justice, L emerges as a formidable opponent, challenging Kira's actions and pushing the limits of their mental duel.
