They told Naomi Misora she was dead for three minutes when paramedics revived her. She sure didn't feel alive. She couldn't even remember coming back to Japan, much less Kira taking her fiance, much less Kira sending her to suicide, maiming her and robbing her brain of speech. She had almost given up hope of recovery until a mysterious figure gave the promise of revenge: the chance to kill those who wronged her, if only she can find them.

Aphasic and adrift, Naomi's going to join the Kira investigation to win her life back. She's going to help Misa Amane discover who she is, and discover a connection with her. She's going to make Light Yagami have to think on his feet, and present him with a new opportunity. She's going to solve some serious problems for L, and then make some serious problems for L. And she's going to make a hell of a lot of things get a lot more complicated.
