Fading Light

Misa Amane was undercover with Light Yagami, the original Kira, in trying to steer the police investigators, most importantly L, the main detective in the case, away from their suspicion of them both.
Neither of them wanted to be discovered as one of the two Kira, deadly Japanese citizens blessed with the power of a book that has the power to kill within 40
seconds just by writing a name with an image of the person in your head.
As sudden tragedy occurs, Misa falls into a blind insanity.
