The last foe is a new "Death," created by man. To solve the Kira Case, L (Kenichi Matsuyama) leaves Los Angeles convincing Kira is in Japan. At the same time, his intuition tells him that he may never be able to return to Los Angeles again...
Known as Kira, Light Yagami, using the Death Note, attempts to become God of a criminal-free new world. By L's ultimate choice, the Kira Case closes, but, at the same time, L loses Watari who was L's most trusted partner.
After Watari left, L takes on the task of solving the cases left in Watari's file. As all the cases are solved, a "gift" addressed to Watari arrives. The gift is a little boy. From the SD card the BOY has in his possession, L learns that the child is the only survivor of the Thai village, which was exterminated. L also discovers that a huge conspiracy, utilizing a man made "Death," was on the move behind the Thai village tragedy.
Meanwhile, L has another visitor. The girl's name is Maki, and she tells L that she has brought something her father, who died a horrible death, told her to deliver to Watari. As L realizes the item the girl brought is, indeed, the "Death" in question, pursuers are closing in. Protecting the two children, L physically makes moves to solve the horrendous case.
However, there were only 6 days left for him.
