Death Note: Desu nôto - Season 1 Episode 9

L reveals that he had tricked Light into writing into a fake notebook, thus; exposing the latter as Kira. After Light confesses to L, the rest of the task force enter the warehouse only to see L die from a heart attack, courtesy of Mikami. Since only L heard the confession, Light convinces the task force members that L gave Light his real name and wrote it down in an act of self-defense. After L's funeral, Near takes over L's duties as head of the task force and focuses the investigation on the prosecutors that came into the task force headquarters the day L died. Meanwhile, Light meets with Misa and Mikami at a rooftop and restores Misa's memories of being the second Kira by tying a scrap from the red notebook onto her wrist. Later, task force member Shoko Himura betrays her team and conspires with a mysterious group of men to kidnap Sayu, Light's sister. Himura and her associates demand that the task force hand over the black notebook in exchange for Sayu's life.
