Wow. I updated. I think this calls for a national holiday.
I think it was mufuzu who came up with this idea.
Had a fun time writing it- un-beta'd so if there are mistakes, tell me plez.

Kira has affected my whole life.

I was one of the ones who grew up through the years in which he controlled humanity- I was there and saw the criminals dying one by one in their prison cells. I watched from my living room, like the hundreds of thousands of others. Yet there was something different about me.

Where hundreds of thousands may have respected, hated, loved, campaigned for or against the monster known as Kira, he was always but a figure to them- someone famous, that you never met but knew existed. I was different.

Kira was my brother.

My mother never knew, my father died before we knew for sure. I was never told this. They told us that he had died fighting Kira- fighting in the name of the law, as I thought my brother would always have wanted to. He was compelled by his justice, and my mother and I both thought it was a fitting end to his life.

Many people never knew who I was- I was always Raito Yagami's little sister, constantly overshadowed. This never really bothered me- he was a genius, I knew I couldn't compare to him. But to say he was the only who received brains in the family would be a lie- I, no matter how feeble compared to him, am not the idiot that I am commonly perceived to be. I may not be a genius, but to this day I thank god for that fact. My brother was a genius, and look what happened to him.

To say that I worked it out would be a lie- no thought went into the process, no skill was involved. Just a gut feeling and some good luck. I could tell that they lied when they said he fought and died bravely, because they looked so uncomfortable. And none of them could look either me or my mother in the eye.

Also, I had noticed some change in my onii-san's behaviour- he was more easily annoyed, prone to mood swings. I didn't see him very much, the Kira case having consumed most of his time, but the few times I did were enough. There was a period where I was captured, one of the most frightening times of my life. But looking back on it now I feel nothing but a bleak emptiness to know that the person that got my out alive was the one who had caused the entire charade- the person who indirectly killed my father.

I feel that I have digressed, but seeing as this will all be over soon I cannot bring it upon myself to care. My life is slipping away, and I see no reason to continue it if the emotions and feelings I once felt have disappeared. Mine is just another life, one amongst billions that could be silenced in a second, and soon shall be. But I must finish my story first, even if no-one shall ever read it.

I often used to go into my brothers room, sit upon his bed and cry. I felt that he was still in there- not Kira, but the calm, quiet, sensitive older brother that I once knew. One day, it came upon me to turn on his computer- no particular reason, just to see what happened.

The things that I saw there were astounding. Not only did he have the passwords for all my fathers supposedly secure information, but he had access to police accounts, hacked into news sights and so much more. This was all that I uncovered before I had to make myself stop- there was a single thought running through my head.

All these websites, folders, accounts- all of them lead back to news of criminals.

This may purely have been because he was researching deaths, hoping to help my father. But somehow I knew that it wasn't. I sat at the computer, feeling everything slide into place in my head for hours. It wasn't until my mother called me to supper that I even realised that I'd wasted half a day. Except it wasn't a waste.

The things that all suddenly made sense- his constantly locked doors, the way he withdrew and became more secluded, the way that he was start yelling in his room for no apparent reason… I understood them all suddenly. The fact that he had been the only one to die in the expedition in which Kira was defeated should have struck me as odd in the first place. The sudden, glaring facts stunned me.

This all happened exactly one month ago. I poked around his files, as well as my fathers, a bit more, even though it killed me inside. Steadily, I realised what I should have from the start- my brother was a murderer, a cold blooded serial killer who killed everyone in his way in the name of his supposed justice. It was at this point that I found that no more tears came, that my words and emotions froze in my throat and that everything lost its colour.

I wish never to tell my mother of this- but this note has to be read. The truth killed me inside, and I can't think of how it could help anyone, but news that Kira really is dead must be worth something, right?

And, the worst thing is, as much as I detest the things he's done, and his warped sense of supposed justice, I can't help but love him. He was my brother- he never struck me as someone evil. I cannot shake the memories I have of him in which he smiles- happily, purely. Then these images clash with the bloodstained hands that are all I can envision, and the image tears at my insides. I cannot continue to live with both truths- Raito Yagami and Kira existing in the same body.

So I shall not live with it. I'll take the easy route.

This is Sayu Yagami- Kira's little sister.
And maybe I'll meet my brother in hell.
