This section provides an overview of the basic elements of the series and highlights its defining features.

Main Characters and Their Roles in the Story

Here is a brief explanation of the main characters and their roles in the story:

• Light Yagami: The protagonist who transforms from a brilliant high school student into someone aspiring to become the “god of the new world.” His efforts to enforce his own vision of justice through the Death Note drive the entire narrative.
• Misa Amane: A popular idol and the second Kira. She acquires a Death Note from the Shinigami Jealous and is deeply loved by Rem. Her obsessive love for Light causes her to act extremely, showing both a self-sacrificing nature and intense emotions that influence the story’s direction.
• Soichiro Yagami: Light’s father and a senior police officer. As the head of the task force investigating Kira, he strives to uncover the truth while struggling with the suspicion and trust he feels toward his son.
• L: A globally renowned detective and Light’s greatest rival. Beneath his odd behavior and posture lies sharp intellect. His psychological battles with Light are filled with tension as they attempt to uncover each other’s identity.
• Near: A candidate to succeed L. With a calm demeanor and unique investigative style, he closes in on Light and plays a decisive role in the story’s final act.
• Mello: Another candidate to succeed L, who uses different methods from Near to pursue Kira. Proud of his position as L’s successor, he occasionally lets emotions affect his judgment but becomes deeply involved in the plot through alliances with the mafia and incidents like the kidnapping of Kiyomi Takada.
• Teru Mikami: Chosen by Light as Kira’s proxy. A person of strong moral conviction and fanatical loyalty, his independent actions ultimately contribute to the collapse of Light’s plans in the final stages.
• Ryuk: The Shinigami who originally owned the Death Note. He drops it into the human world out of boredom, setting the story into motion. He remains a detached observer throughout.
