Light Yagami, the protagonist of the anime "Death Note," manipulates his own image and public perception in several ways to further his agenda of creating a world without crime. He initially presents himself as a diligent and intelligent high school student to maintain a facade of innocence and avoid suspicion. He strategically uses the Death Note to eliminate criminals, gaining public praise and recognition as the mysterious vigilante known as "Kira." By doing so, he positions himself as a savior and instills fear in potential wrongdoers, thus shaping public opinion in his favor. Additionally, Light carefully manages his interactions with others, appearing charismatic and trustworthy to gain allies and manipulate those around him to serve his goals. Through these calculated actions, Light Yagami effectively controls his image and public perception to advance his ultimate objective of becoming the god-like figure ruling over a crime-free world.
