Light Yagami is the protagonist of Death Note, a manga series written by Tsugumi Ohba and illustrated by Takeshi Obata, serialized from 2003 to 2006 in Shonen Jump. He is a high school student who discovers a supernatural notebook that kills anyone whose name is written in it. He adopts the alias Kira and attempts to create a crime-free world by killing criminals, becoming the series' central character and primary antagonist simultaneously.

What Is the Death Note?

The Death Note is a supernatural notebook originally belonging to Ryuk, a Shinigami (death god) who drops it into the human world out of boredom. The notebook's primary rule is: the human whose name is written in this note shall die. Additional rules specify that the writer must have the target's face in mind while writing to prevent accidental deaths, and that a cause of death can be specified within 40 seconds. If no cause is specified, the target dies of a heart attack. The manga contains dozens of additional rules that create strategic complexity throughout the series.

What Is Light Yagami's Goal?

Light's stated goal is to eliminate crime by killing criminals, creating what he calls a new world over which he will rule as its god. Initially motivated by a sense of justice, Light's methods become increasingly extreme as the series progresses. He kills not only convicted criminals but also FBI agents investigating him, innocent people who threaten his secrecy, and eventually anyone who opposes his vision. His moral decline is the central theme of the series.

Who Is L in Death Note?

L is the world's greatest detective, known only by his alias. He is a reclusive genius who sits in unusual positions, eats primarily sweets, and possesses deductive abilities that rival Light's. L determines that Kira is based in Japan's Kanto region within days of the first murders and correctly identifies Light as a suspect early in the investigation. The intellectual battle between L and Light is the defining conflict of the first half of Death Note.

Is Light Yagami a Villain?

Fan communities remain divided on whether Light's vision of a crime-free world justified his methods.
