The song I used is called Zombie by the Cranberries. The only warning, I guess, is violence, angst and (some) horror (I think).
Another head hangs lowly,
Child is slowly taken.
And the violence caused such silence,
Who are we mistaken?
Kakashi whimpered, curling tighter into a ball, the screams and sobs echoing in his mind. He could see the ninja around fall to the ground, their last choking breaths seeming louder than the screams around him. The screams that surrounded him. The cries that dwindled into those last choking breaths.
But you see, it's not me, it's not my family.
In your head, in your head they are fighting,
With their tanks and their bombs,
And their bombs and their guns.
In your head, in your head, they are crying...
His body went limp as he fell back onto the floor, eyes wide with fear and horror. He could see the body on the floor next to him, reaching for him, mouth open in a silent scream. The marred face contorted in pain, the flesh seeming to peel away. And then it vanished and he was left sitting on the floor, reaching for something that wasn't there.
In your head, in your head,
Zombie, zombie, zombie,
Hey, hey, hey. What's in your head,
In your head,
Zombie, zombie, zombie?
Hey, hey, hey, hey, oh, dou, dou, dou, dou, dou...
He could hear the jutsu's and the orders being shouted, as more and more of his fellow ninja fell to the ground, blood staining their uniforms as some had kunai sticking out of their chest, while other's were merely sliced in half.
Another mother's breakin',
Heart is taking over.
When the vi'lence causes silence,
We must be mistaken.
He could hear the parents and families sobbing as they lay flowers by the graves. They sobbed and cried, some cursing the way of the ninja for 'taking away their precious loved ones'. And Kakashi knew they would never understand.
It's the same old theme since nineteen-sixteen.
In your head, in your head they're still fighting,
With their tanks and their bombs,
And their bombs and their guns.
In your head, in your head, they are dying...
Kakashi stumbled down the hall, not reaching for the walls to steady himself only because their dead faces were on the walls. And then the face were gone, and for a moment, there was silence. But then, blood splattered the walls, the screams becoming louder and louder. Nearly unbearable.
In your head, in your head,
Zombie, zombie, zombie,
Hey, hey, hey. What's in your head,
In your head,
Zombie, zombie, zombie?
Hey, hey, hey, hey, oh, oh, oh,
Oh, oh, oh, oh, hey, oh, ya, ya-a...
And Kakashi felt empty.
