A lone swordsman: I have never been alone. I have always had Lord Orochimaru. I fought for him. I killed for him. I lived for him. I nearly died for him. I was thrown away by him. I am alone again. I am surrounded by darkness again. Just like I was when I was a child.
(A flashback. We see a wooden jail in a pitch-black cave. In the cell we see a young boy, casually hacking away at the back wall.
Boy: Why am I in a place like this? Did I do something wrong?
(The jailhouse door opens.)
Boy: Who is there?
Kaguya elder: Does it matter?
(The cell door opens. The boy climbs out. He cannot see his releaser, for he is standing in the dim light, intense light to the boy's eyes.)
Kaguya elder: Kimimaro, the time to use you has come. For the sake of the Kaguya clan…fight!
(In a field surrounded by people who share a distinct family resemblance with the elder.)
Kaguya elder: Now, we will attack the Hidden Mist Village. It's time for us to act. It's time to let our brutality known. Let them know of the Kaguya clan's brutality.
(And so, the Kaguya clan began their rampage of destruction and murder.)
Orochimaru (watching from a distance): So it has begun. The Kaguya clan, they can only recognize their own existence through fighting and killing. What a bunch of fools. That bunch of fools, because they enjoy genocide, they cannot adapt to changes. In terms of power, fighting against an organized military … they are only a bunch of fools marching to their death.
(Back in the burning village)
Kaguya elder: So, there are only a few of us left. Looks like we've been surrounded, their defenses are stronger than we thought. It can't be helped. In that case, kill as many as possible, even if there will only one of us left! Let's have some fun!
(In the last final slaughter of the demented Kaguya clan, no one noticed the young battered boy slip away, and fall asleep on a high tree branch. When he woke up, he found that he was the last one left. He wondered for hours before meeting Orochimaru. Orochimaru took him in, brought him to the Land of Sound, and trained the last member of the Kaguya clan; known for the ability to manipulate their own skeletal structure. For years, Kimimaro served Orochimaru, killing, fighting, protecting. Until the day the Sound Five abducted Sasuke. They were bringing him back to the Hidden Sound Village, but all six member of the Sound Five were defeated in battle by the team of Konoha and Sand genin sent by the Fifth Hokage. The team included the future Kazekage; Gaara of the Desert. Kimimaro was sent to deal with him, but used a technique that made two of him, not a mere clone, but an actual second body for his one mind; this was made possible by only his bone-manipulating blood trait. One fought Gaara, while the other protected Orochimaru incognito. Kimimaro fell in battle to Gaara, but the other Kimimaro was still alive, and watched from the shadows as the flame on the candle went out.)
Kabuto: You don't think Kimimaro fell…
Orochimaru: I don't care about Kimimaro anymore, I care about Sasuke.
(End of flashback)
Kimimaro: I was heart-broken. Four of the six died, one was captured, and Orochimaru didn't care. As long as Sasuke made it to him, it was all just small payment. After all, the six of them were just pawns to him. Now, I live to fight him.
Zaku: I live to kill him back.
