Question

How does Light Yagami manipulate Misa Amane's memories to protect his identity?

Answer 1

Light Yagami manipulates Misa Amane's memories by using the Death Note to make her believe that he is not Kira, the identity he uses when killing criminals, but instead a normal person who supports Kira's actions. By doing this, he ensures that Misa does not suspect him of being Kira and protects his true identity as the one behind the killings.

Answer 2

In the anime "Death Note," Light Yagami manipulates Misa Amane's memories by using her affection for him to his advantage. He convinces her to give up ownership of her Death Note, therefore losing her memories associated with it. Light then manipulates her memories further by using his own Death Note to make Misa forget all the events related to Kira, including his own involvement, thus protecting his true identity as Kira.
