Prologue

He stood in the clearing, panting, facing his opponent. The sky was getting darker. The wind was cold and fierce, hurting the injured bare skin of his torso. He swallowed hard, and, letting out a growl he ran toward the other young man, his katana raised.

Naruto countered with a kunai at the last second. As they sparred, he tried to figure out how much strength the blond shinobi still had left. Sasuke himself was out of chakra, he was completely exhausted, and was fighting only by sheer will. After using his ocular techniques so much, and then his lightning and fire elements techniques, his energy and chakra had left him.

Naruto had seen through all his illusions, and had countered each and every one of his attacks brilliantly. In Kyubi mode, or in Sage mode, he had impressed Sasuke so much by his talent and skill. He was no longer the clumsy twelve years old he used to know, that was for sure. As they crossed blades their eyes met. Deep blue eyes were looking dead serious, frowning at him. Sasuke pulled back his sword and attacked again, lending powerful blows, but it was useless. Naruto was evading and side-stepping them all.

He simply couldn't figure him out. Did Naruto have any chakra left? Possibly. Maybe he was holding back, not wanting to kill Sasuke. Even though they had just tried to kill each other for hours now… Or so it had seemed anyway. Apparently they hadn't tried hard enough…

Even though they were both hurt, nothing was fatal. They had both lost a lot of blood, and were exhausted, but no vital organ was damaged, no bone was broken.

Pushing his body to its limits, Sasuke managed to move even faster and the tip of his blade slashed Naruto's stomach before the latter could counter it. The blond stepped back and growled in pain, clutching his ripped and bloody shirt. His blue eyes darkened in frustration, and he produced two shadow clones. So he still had chakra after all…

Sasuke quickly moved back, anticipating the blond's attack. Sure enough, one of the clones attacked him while the other one was creating a rasengan. He slaughtered and got rid of the shadow clone easily enough, but Naruto hadn't lost any time. Sasuke gasped and threw himself on the side, evading the powerful rasengan by a split second.

He rolled on the ground and sat up, panting. He brushed his raven bangs away in annoyance, and looked up at Naruto. Then his dark eyes widened. The blond seemed in pain. He was down on his knees, hugging himself. He let out a pained gasp, and then raven birds literally appeared out of nowhere around him.

Immediately Sasuke's mind started racing. This was Itachi's chakra. But why was his brother's chakra coming out of Naruto? What the hell was going on?

"Naruto…" he started in a rasp voice.

But the blond couldn't even hear him. After the dark chakra had left his body, he fell to the ground. Sasuke frowned and got up to his feet painfully. He was about to walk up to Naruto, when everything around him disappeared. In its place were thousands of raven birds, and deep red fog all around him… Again, Itachi's chakra, of course.

Sasuke looked all around him in confusion, trying to break through the genjutsu, to understand what was going on. But then it was as if an invisible force hit him, and he fell on his back roughly, hitting his head on a sharp rock. Everything became black as he drifted to unconsciousness…
