The C-Kira Story

The Death Note One-Shot Special was serialized in a 2008 volume of Weekly Jump, and xplains what happens in the series three years after the Kira case is resolved.

Plot
Near is shown as the new L (the third chronologically). A new Kira emerges who had gained a Death Note from the shinigami Meadra (Midori in Viz's translation of Death Note: How To Read 13), who had received the additional Death Note from the Shinigami King by bribing him 13 apples she had taken from the human world. The new Kira murdered elderly people in Japan to "relieve their pain." When Near's SPK subordinates asked him why he wasn't taking any action, he replied that he was trying to think what the previous L would have done. He finally reaches a conclusion that the prevailing Kira was just a killer without a purpose, and he labeled the killer as "C-Kira" for "Cheap Kira." He announces on national television, under the alias of "L," that he was not interested in the case and that he had deduced that this Kira was not the real Kira but only an "abominable murder." This resulted in the suicide of C-Kira. Throughout the 40-page manga chapter, the identity of the new Kira is not revealed.
