Light Yagami in the anime "Death Note" uses the power of the Death Note to influence public opinion by strategically targeting and eliminating criminals. This causes a significant drop in crime rates, leading many people to support Kira's actions as they see him as a vigilante bringing justice to the world. Light also uses his intelligence and charisma to manipulate media coverage and public perception, portraying Kira as a savior and hero. Additionally, he creates a cult-like following by exploiting people's fear and desire for safety, further solidifying public support for Kira's actions.
