Light Yagami, the main character in the anime "Death Note," is known for his strategic and manipulative nature. He often uses manipulation of memory and perception to further his plans and schemes. By controlling how others perceive him and manipulating their memories, he is able to maintain his facade as a high-achieving student while secretly using the Death Note to eliminate criminals. This manipulation allows him to avoid suspicion and continue his vigilante activities without being caught.
