The New Kira.
Light couldn't believe it, he was about to die, and his murderer wasn't L. Hell it wasn't even Ryuk, it was some bratty European.
The boy sat next to him by Light on his bed, absently talking to him as Light's body slowly died, cell after cell fighting for survival before succumbing to the poising flowing through him.
"I feel you should know that I actually idolised you" the boy said. "My parents were murdered before my very eyes, my sisters raped before joining them, I only survived because their bullet missed my heart..." he continued his narrative while Light lay paralysed. His once great mind slowly failing as the nerve endings that it existed within ceased their sparking forever.
"… it's still there you know- that bullet, they couldn't take it out- I think I can feel it on cold days, an icy blade by my heart, always there to remind me of what I lost that night…"
Light had tried to struggle, he had begged Ryuk with his eyes to help him, to kill this insane foreigner before Light's life was snuffed out forever, but the Shingami just laughed gratingly and watched on. Only now did Light understand the true horror of Death, every second he could feel himself turning to nothing- few people ever realise what death is. But now Light was one of the minority, it was nothing, you simply didn't exist anymore, perhaps others could look forward to some kind of afterlife but Light knew at this very moment that there was nothing after death for him.
"When I woke up in the hospital I wanted to die, but before that I wanted to kill the men who took my family away. But I couldn't, I slowly realised this as I lay drugged out of my mind, the men who had stripped me of my innocence, they were the ones who hunted the lawbreakers, they were the ones who the mindless masses flocked to in their time of need. I was nothing more than a homeless charity casse, my family the lowest rung on the ladder of society."
The boy's voice was steady despite his words, his blue eyes never straying Light's amber ones. "So I prayed, I prayed from my hospital bed for god to strike down these men, these monsters, I prayed for hours, for days until I couldn't pray anymore but the men who killed my family still lived. They ate their rich foods, and drank their fine wines while my parents rotted, they laughed with the wealth and the famous while my sisters spirits screamed for justice. They just kept on living their lives like my family was nothing, like they never existed" the boy hissed. "They even claimed the credit for catching the killer, they set up some poor men from a nearby store, one them was my friend. Now Kira, now God, can you possibly imagine what I felt when I heard about that?"
The boy smiled for the first time, the expression stark against his emotionless eyes. "But you answered my prayers, you stuck them down when no one else would, you answered my prayers when the rest of society drugged me senseless when they couldn't stand to hear the truth! You forced them to join my family in the afterlife, you granted me justice!" The boy's eyes lost their icy quality for second, shining in remembered joy before returning to their mirror-like state. "When the doctors finally let me go I ran to the nearest Kira church and I swore my eternal loyalty to you before the enlightened. I spent as many hours as I could there, learning, and then teaching your values. I truly believed in you, and I would have died for you". The boy's voice became cold again.
"But then I heard the church proclaim Kira god, the same church who was formed to worship justice above all else was now bowing to their leader as a deity". Light struggled to call out for help but nothing more than a pathetic whimper escaped his throat, he felt the world to turning to nothing, the darkness and the emptiness coming closer to turn him to nothing.
"At first I was shocked, no person, no matter what their powers should be worshipped as a god, then I researched L and his working, I found and I tracked the FBI agents that were sent to Japan. And you'll never guess what I saw next" the boy's voice was thick with anger and betrayal. "I saw them die. I was actually watching one through a street camera when I saw her struck down, I later found the last moments of Raye Penber's life on tape as well, and that was when I knew" the boy hissed. "I knew that the one who had given me justice, that had let me family rest in peace, the person who I would have died for without hesitation had become the same as the men who killed my parents!" The boy's voice cracked.
"I saw what you had become and I knew what had to be done! I found your limits and I found your identity, it wasn't easy but I did it. I watched for days and I found the source of your powers, this 'Death Note'", the boy held the Death Note in his hand and flipped through the pages. "It was a while before I was able to work out that trap of yours; it's not easy spying through a window after all. Of course once I got my hands on this note I realised that Kira did not have to die, only Light Yagami had become corrupt and twisted. All I had to do was wait until your family left you alone in the house for one of your sisters school plays and I simply poisoned your study snacks".
Light would have been horrified if he was still capable of any emotional depth, the boy had killed him through the simplest of means. The god of the new world was going to die not because he had been defeated by L, but because a heretical former follower poisoned him!
Light dimly felt the bed shift as the boy stood up, "don't worry Kira, I will continue your good work. Your taint will expunged from Kira and you may go to your grave in peace knowing that the new world you fought for will come for I am Kira now!" The boy walked out the door, taking the Death Note with him, "goodbye Light Yagami, may your sins be forgiven in death".
Light desperately tried to move, but to no avail, his body was more than half dead and his mind was joining it quickly. He was paralysed in his own room, the room that he lived in, the room that Kira lived in- no Kira was the boy who just left wasn't he? Then who was he? His chest felt empty, had his heart stopped? He couldn't remember, he couldn't see, he couldn't feel, only the darkness and the cold… so cold…
Light Yagami's brain gave off one final spark, then there was nothing, nothing but a cooling body left on the bed.
Light Yagami was dead.
