Author's note:

This is my first Naruto fanfic. I know that the general idea is not new, so please, no flames. Also I would like to know what pairings you would like to see. I will not do a Sasuke/Naruto or something like that. Keep it boy girl PLEASE. I would also like some input on how long you feel a chapter should be. I love long stories, but I can't find the time to write long chapters. My last attempt burned me out after 6 chapters and 26,000 words.

I'm rambling, but I'll try to keep this brief. I'm not sure what kind of new and original elements I can add to a genre that has been so thoroughly explored. (over 180,000 fanfics is amazing.)

Summary:

Sasuke sees Kubified Naruto about to eliminate Pein, but also the rest of the elemental nations in a last ditch attack and he does the only thing he can do; a space-time warp to the past. Now back in their pre-Genin days, how will Naruto and Sasuke cope with new challenges and burden of knowing the future? Will they change the past to reshape the future they just came from, or will they tear apart the past in an effort to finish the other off?

Chapter One: A Fresh Start

Naruto growled…or rather the Kyuubi growled as he faced Pein. The real Pein. The rain poured down soaking the leader of Atasuski, while the Kyuubi's unnatural chakra evaporated the water as soon as it touched the swirling mass of red. Pein jumped back and settled onto a building that rose above the rest of the Hidden Village of the Rain to put some distance between himself and the Biju host.

Surprisingly the Kyuubi also jumped back and not surprisingly, powered up a new attack. To those witnessing the battle gaped in awe at this new attack. The Kyuubi compacted a huge portion of it's chakra into a tight ball which turned almost pure black. That was not all. Rather than swallow the chakra and blast it at Pein, a blue aura surrounded the attack, swirling not too much unlike the Rasengan. Suddenly fire, lighting, wind, water and finally earth formed into orbits around the black center, rotating ever faster.

Sasuke couldn't help but feel the power of the upcoming attack. Even miles away the chakra build up could be sensed. Damn it! I need to more FASTER! Sasuke's urgency and anger threatened to overwhelm him as he surged forward pushing his body to the limit. Nothing would stop him of exacting his revenge on Pein. Pein had destroyed Konoha; the very thing that Sasuke wanted to do after completing his avenger role and killing Itachi. No one gets in the way of my revenge and lives.

Sasuke arrived at the battle field in time to witness the Kyuubi bracing itself for the kick-back of its attack. It planted all nine tails deeply into the ground and crouched as if preparing to spring on an unsuspecting mouse. With the Mangekyo Sharingan activated, Sasuke darted forward and cast his jutsu. "SpaceTime Warpfield!" (This is the one Madra Uses on Shino's bugs in the manga)

Instantly he knew something was wrong. He saw the Kyuubi sucked into the field, but HE was going with it. Shit, Shit, SHIT! This isn't supposed to happen! Sasuke felt his entire body stretch and move under the effect of the jutsu. Try as he might, he couldn't cancel the move. It was going to take him down with him. All of a sudden he blacked out…

Naruto woke up with a groan. Where am I? He asked himself groggily. He rolled out of bed and hit the floor with an alarming thump. What the hell? Since when did the world get so much bigger. He carefully sat himself upright and leaned against his bed like he used to do…That's it! He knew this place looked familiar. Is this a dream? Naruto shook his head. My forehead protector is gone! He realized in a flash as he missed the familiar weight against his forehead.

"Something just isn't right." He moaned. "I was fighting Pein and the the Kyuubi came out and…and…" He trailed off as he realized he couldn't remember anything after he had relinquished control to the Biju. Did I faint? He asked himself. No…If I fainted I would have ended up by his cage. Naruto quickly folded his legs and closed his eyes as he prepared to talk with the Kyuubi. He felt himself slip into the cold waters of the underground labyrinth that was his sub-conscious. Before him stood the metal cage door with the familiar seal still on it. He peered into the depths of the cage and shouted, "Hey Demon! You there?"

Almost instantly a pair of red eyes opened. A pair of harsh, fiery eyes that belonged to the nine tailed demon fox; the Kyuubi no Yoko. "What do you want brat?" The Kyuubi growled.

"Oi! You know what the heck happened to us?" Naruto demanded. "I mean one moment we were fighting Pein, the next I'm waking up as if I was in the academy."

"You mean to tell me you didn't feel that accursed Sharingan pull us into a vortex?" Naruto blinked at the Kyuubi's question. "Let it suffice to say that we have been sent back in time." The demon fox let this information seep into his host.

"You mean Sasuke did this?" Naruto asked looking up at the fox for confirmation.

"Yes…" The Kyuubi hissed. "Unfortunately for him, he was sucked in with us. Apparently he hasn't perfected the technique."

"So are you telling me that we're stuck here with an over-powered Uchiha and to top it all off, we're both like 12 years old and in the academy?" Naruto summed up the situation.

"Like it or not, you are going to have to repeat your life." The Kyuubi replied.

"If I'm back in the past, why do I still have my memories?" Naruto asked the ancient beast.

"Probably an error in the technique," The Kyuubi mused. "Since he was new with his Mangekyo Sharingan, he hasn't mastered it. That margin of error could possibly account for your retained memories."

"So what skills do I still have?" Naruto asked yet another question, annoying the demon.

"You'll have to find that out yourself." The Kyuubi retreated to the far reaches of its cave. "I'm taking a nap."

Sasuke woke up similarly to Naruto with a pounding headache. His eyesight was foggy, but that cleared away as he blinked his eyes. Looking around, he found himself in his room inside the Uchiha compound. He hadn't lived there since just after Itachi. Is everyone still alive? He quickly stood up, causing his vision to blur and head to spin, but he gritted his teeth and walked to the door to his room trying to ignore the pain. He stumbled out of the room as if he tripped on the doorway to find the house completely quiet. No one's here. They're all gone. Memories of that terrible night leapt into his vision unbidden and unwanted. Why do I have my memories? If I went back in time, I shouldn't have them. Cursing his weakness, he chided himself on getting caught in the warp field in the first place. I should have been stronger. I should have been able to control IT!

He wandered around the compound staring at the old sights, talking in the morning air, he searched for a calendar. It wouldn't look good if I didn't show up the academy. That would be a sign of weakness. He walked into a bathroom and looked at himself in the mirror. The curse seal was gone and he wasn't wearing a forehead protector. He tried to look at the old him and accept reality; the reality that he was stuck in the past, stuck with the prospect of regaining all of his powers all over again. Almost on a whim, a last thread of hope, Sasuke closed his eyes and tried to activate his Sharingan. When he opened his eyes, a rare smile broke out. He still had the Sharingan!

The Third hokage woke up with a start. He had without a doubt sensed an enormous Chakra spike. It had sent a shiver down his spine as he recalled a similar feeling 12 years previous when the nine tailed fox had attacked the village. He needed to find Naruto and talk with him.

But something still wasn't quite right he had felt the Kyuubi's evil chakra, but it felt suppressed by a different power. A power he had felt awaken when Itachi murdered his entire clan with the single exception of his younger brother, Sasuke. He would have to talk with both of the young boys today. He sighed, life never was fair, but it was never this cruel. So much for a pleasant day.

Naruto quickly re-adjusted to his old life style, and was soon devouring cup ramen that he found in a cabinet. If he was stuck in the past, he might as well make life a little better and train his tail off. Naruto was fairly comfortable with the Kage Bushin as he had just created ten clones to clean up his apartment. I'll have to wait for after class to test the Rasengan. He thought to himself and slurped up the soup from the ramen. Not even bothering to throw the remains of his meal into the trash, Naruto walked over the nearest wall and placed one foot on it. After a second of concentrating he cautiously lifted his other foot off the ground and walked up his wall and hung from the ceiling.

Naruto grinned at the up-side-down world. "Oh yeah! I can still walk on walls!" his voice rang through the early morning startling several birds which took off from their perch below his window. Naruto started to do a little jig while still attached to his ceiling, yet quickly wound up on the floor in a heap. "Oww!" he groaned and rubbed the back of his head. What clones he still had dispelled as his concentration slipped, canceling the justu.

He slowly shuffled his way back into his room and pulled out his orange jumpsuit. I used to wear this thing? Naruto asked himself. Oh well, it's all I got. He shrugged on the orange contraption and set off for the academy. His walk wasn't long. He didn't live that far away from the ninja school, and it didn't take more than five minutes to walk there. As he entered the grounds, he spied the Uchiha entering the building just as the Uchiha spotted him. Their eyes locked and chakra flared.

Alright, I know that that wasn't a very long chapter. I will get better. I've got a lot of ideas to cram into the next year of their lives. Please tell me what pairings you like. Right now I'm thinking Naruto/Hinata and Sakura/Sasuke.

Please Review. I want to know how I did.
