Introduction /After Kira's Death
Although this very story is not in the narrative nor about any of the following, though I believe a fair explanation should be explained to thy possibly faithful reader. L. Mello. Matt. Three that gave their lives fighting toward the end of Kira's reign. Meanwhile Near lives on, claiming the title of 'L'. Kira was thankfully brought to his knees and killed by the very means he had murdered so many. So that's the end.
I mustn't be the only one who believes otherwise, and it turned out my suspicions were correct. All of the above mentioned turned up again, miraculously, alive; and why exactly does this fact rest assured? Well, for certain we all agree that Shinigami behold many mysteries and the strangest of gifts and powers of any stretch of the imagination. Therefore it takes a Shinigami itself to write the name of a human within the pages of a Death Note for that particular person to truly die. If it is a human attempting to kill another, the one who's name lie in the Death Note, will merely temporarily die. Or rather their soul will not fully join that of the truly dead, for it wouldn't yet belong there.
This fact alone is something Ryuk either failed to inform Light or had no knowledge of. For it also seemed that Rem was quite uninformed of these qualities—otherwise she would have told Amane Misa within a moment's notice. Light, himself hadn't noticed because it was in that moment where his ego was at its highest and his reign at his fiercest that those whom he had murdered began living yet again. And anyone who had visited the realm of the dead and returned, even the most vicious criminal of the century, would have ceased killing or any other deed that had caused them to be sent to that very hell hole in which they had just returned. I am quite confident even the most skeptic would agree. These are the reasons Light Yagami failed to notice this error of his. It was until after the great Kira case had been long since solved that it was revealed to the world that those whom had been murdered were coming back to life one by one.
Then L returned.
Though only a few knew about his death, it came as a shock. Even to that so level-headed Near who could only see it coming in a matter of time. Soon enough, Mihael Keehl and Mail Jeevas were back on their feet; these two, more commonly known as Mello and Matt.
Near and L—with personalities so alike—both preferred to work alone and on separate cases. Though there came a few that they came together and solved within a matter of weeks that would have otherwise been months if they had decided to work alone. Mello continued in his races against Near, Matt loyally at his side. On the third case that Mello had rendered a 'race' between himself and Near, it turned out that Mello and Matt had solved the case before Near. Well, there's a first time for everything, I suppose. Not that I didn't give a laugh or two at Near after this news. Personally, in my own eyes, I had never had taking much liking to Near. I would have believed Matsuda correct on his theory of Near killing Mikami, if there hadn't been so much evidence against it. Still, you must give Matsuda some credit.
Then there is someone whom is not mentioned in the series, and demanded her identification never be stated in the story, so they erased her from the case altogether when revealing it to the public. She had not died in the attempt of proving Light was guilty—she hadn't died at all. Much of the credit for everything she had uncovered in the case was split between Light, L, and other members of the investigation. Not that she had figured everything out, no, of coarse not. Though because she had never been mentioned, somebody had to come up with the ideas. Such as that Kira can kill in more ways than just Heart Attacks—she had been the one to uncover this fact. Not Kira himself. For even without his memory, Light Yagami hadn't given much to the investigation. Not because he wasn't intelligent enough, but because Light had somehow sensed that it wouldn't benefit himself in any way—though that's beside the point.
Her name was 'Key'
Or such was her alias, anyways; or rather, my alias-slash-nickname. Key had joined the Task Force sometime before Light had joined them, before the second Kira, and yet after what was left of the Task Force began meeting with L—or Ryuzaki for that matter—in person. The relationship between L and Key was utterly absurd. Picking on each other left and right, and L keeping a matter-of-fact tone and expressionless face all the while and Key, herself, a lively and sarcastic mix that had the ability to be straight-out blunt at times. Though in the end, when L had died, Key wouldn't speak or eat for a few days afterward. And even after that she carried on L's suspicion of Light Yagami and aided Near when the chance stroke up. She straight out refused a 'no' when Key told Near she wished to join the SPK or at least aid their investigations by spying on Light or on Mikami at the very least. Though Key ended up giving Near weekly updates of suspicious decisions and movements or any other clue that would help lead one step closer to Kira's—or Light's—Downfall.
When L had returned to life, Key rejoiced without letting most of it show. And after aiding L in one or two more cases, she disappeared off of the face of the Earth—going incognito.
Though back at Wammy's, things weren't so smooth. Well, it had been until recently, anyways. One of the orphans obtained a Death Note from either a reckless or scheming Shinigami, and devised a plan to kill the Shinigami when he had discovered the rules. Killing it was only phase one of a plan, though; for he had also uncovered that long lost rule that only a Shinigami can truly kill a human. Soon as he had successfully killed the God of Death, he obtained the substance in which it dissolved into and soon enough afterward ejected the Shinigami remains into his own veins. This caused him to obtain Shinigami-like abilities, without fully becoming a Shinigami. He could still be killed, though he could truly kill using the Death Note.
The Earth is now truly unsafe.
