In the anime "Death Note," Light Yagami uses manipulation of memory as a tool to cover his tracks and deceive others in his plans to eliminate criminals and become the god-like figure known as Kira. By altering memories or planting false information in people's minds, Light ensures that his identity and involvement in the killings remain hidden and that he can further his goals without being caught. This manipulation of memory is a crucial part of his strategy to outsmart his opponents and maintain control over the situation.
