Nature's Fittest
by Youkoeyes

Yukina is dead. She lies here before me. I killed her. She was going to kill me and I was going to let her. Then at the last second I found my sword slicing through her soft abdomen. She fell to her knees utterly stunned and looked in my eyes. They were the same blood red eyes I possessed and the only way you could know such polar beings were related. Her blood red pupils symbolized the life giving power of blood and the healing powers she possessed. Mine symbolize the death it brings as it flows from the body it had once sustained and the power I had to take it with the slight move of my hand. That's why she was going to take my life. She was going to save humanity and I was joined in the effort to destroy it. She hardly whispered her last word but my ears pained so much at hearing it she might as well screamed directly into it.
She whispered, "Brother."
She had known all along even though I did everything in my power to keep her ignorant. Two more breathes and she now lays lifeless before me. I killed my sister. I killed the only thing in life I wanted to protect.
Obviously this turn of events tell me something different. I simply live. So many times I have found myself facing an inevitable death and I instantly pull myself out of it. So many things seem to work against me. It's as if I was never meant to exist but I will even if it means wiping everything out of existence. For an instance, I smirk. Simply living is an act of defiance. Gods know I seek to be such a rebel. Now that's a funny statement. Was I forced to become on or did I choose to be one? All I know is that people never really wanted me around except for Yuusuke and Yukina. But now I'm Yusuke's enemy and Yukina is dead. I killed her.
What do I do with this body? I'm not a coward and I'm not stupid. If I hide the body, I'll have time to get back to Mukuro's hideout and think about what I need to do next. I know that they'll eventually notice she's missing and discover she's dead. I'm completely Yuusuke's enemy now. He didn't want to believe my betrayal but this is more than enough to convince him. I'm completely at the mercy of Mukuro. She's all I have left. I can never really love her. She's too much like me. I can respect her but never have that affection I see between Yuusuke and Keiko. We tried once and nearly killed each other. Now we just except comfort in each other's company, knowing the other can fathom what the other is and stand it.
I shouldn't have been so wrapped up in my thoughts. Kuwabara has just stumbled upon the scene. He's too stunned by the sight of my sister's bloodied body. I make my move and decapitate him. He's better off. People like him, no matter how strong they've proven themselves, are broken by the absence of love. This gives time to escape before the others arrive. I quickly scamper off into the shadows of the forest that surround Mukuro's hideout.
I need to buy some time before I meet Yuusuke. I need to get strong enough to defeat him… him and Kurama. What about Koenma? I'm a fugitive now if not already? Dear gods! I've killed Yukina. Can't think of that. I need to prepare. I need to move forward.
