Light Yagami

Light Yagami is the protagonist and primary antagonist of Death Note, a brilliant student who finds a notebook capable of killing anyone whose name is written inside it. He adopts the identity Kira and attempts to create a world ruled by his personal definition of justice.

Light Yagami as Kira

Disciplined, charismatic, and profoundly arrogant, Light begins by targeting criminals but becomes willing to murder investigators and innocent people to protect his power. Control gradually replaces his stated moral purpose.

The Death Note, absolute control, and the collapse of his justice

Light uses the Death Note's rules, manipulation, memory plans, and the devotion of followers such as Misa Amane. His intellectual duel with L, followed by Near and Mello, exposes how a desire to become a god destroys his human relationships and judgment.
