Precious Treasure of the Uchiha

Summary: For centuries, a child Madara took in lived with the Uchiha clan and was loved above all treasures. But in this day and time,the clan is wiped out, only one remaining. Read on as Naruto tries to solve the murder of the clan and the disappearance of Itachi all the while protecting the last living Uchiha. How will Sasuke cope in the world of immortals?

Needless to say, everyone was shocked that Naruto had changed his mind. When the blond had left the Uchiha Main House, the other teens had immediately questioned each other if someone had done or said something special, but they came up with no answers amongst themselves. In the end, they turned to Sasuke but the Uchiha kept tight-lipped. In truth, he was in as much shock as the others. He had not been expecting Naruto to accept being the lead singer but he was happy, as he suspected it might have something to do with how close they have gotten in the span of a few hours.

In the end, they declared the sleepover a great success before the others ran off to get ready for school while Sasuke calmly walked towards the said establishment. Their classmates were even more surprised by Naruto's change of heart but they grew curious about the name and the music they'd play. Iruka happily wrote them down as The Six Path Sage and gave them the time-plate of when they were going to compete for the rights to be the band representing the school.

The rest of the school day was spent like any other, except the group from the sleepover was much closer than before. They ate together and talked during the brake and some of the more childish ones even exchanged notes during classes, until a teacher caught them and threatened to give them detention. All in all, they acted like normal teenagers and Sasuke, for the first time since his brother's supposed death/disappearance, felt a smile tugging at his lips most of the time.

And then school was out and the group, along with Tenten, migrated to the Uchiha Compound's training grounds for the promised spars and training session. Needless to say, they were all quite excited to see how their resident oldest Immortal was going to fight against the last Uchiha and his two protectors so far. Everyone but said fighters were sitting on the roof of the nearest house to stay out of their way as Sasuke, Sakura and Sai got out of their uniform while Naruto just took off his school jacket and shirt, putting on a black muscle shirt and the coat he always wore. The others were ready when the blond was putting on his hitai-ate.

They were in formation with Sakura in the middle and Sasuke and Sai on each side of her. Naruto observed them with an arched eyebrow, trying to see the logic of the formation. He, of course, knew that Sakura was Kakashi's and Tsunade's student, meaning she must be a medic and Sai was from Root. Jiraiya told him all about them. But he didn't need to tell him that Sakura must have incredible strength if Tsunade taught her nor did he need to know that Sai was a long range fighter. Just looking at him is more than enough of a clue. Sai wasn't built for close combat. He was tall and looked skinny. Sure, as an Immortal, he was a lot stronger than his frame will give away, but he wouldn't stand a chance against someone who had been strong as a mortal, too. Sasuke only had the Sharingan to rely on and that was only as much as Kakashi knew about it. Sure, that was a lot more than any other person knew about it, but Naruto knew a lot more about it. He'll make sure Sasuke learns all there is about his Clan's Kekkei Genkai.

He waved to Neji to let him know he was ready and the other three repeated the gesture. The older Hyuuga nodded and raised a hand. The rest of the shinobi quieted down and settled in for one hell of a fight. On the downwards swing of his arm, Neji declared the beginning of the fight. "Start!"

The three younger shinobi sprung apart and started running around Naruto at an impressive speed, keeping in step with each other perfectly. Naruto resisted the urge to call upon his Sage Mody or even Kurama's power. As talented as they were, it would be unfair to them if they had to face him at one of his strongest points. He had to judge their skills, not send them to the hospital. The first attack came from Sasuke in the form of twenty shuriken and thirty kunai sent his way. Naruto dodged the kunai easily but Sasuke had attached string to some of the shuriken and was pulling on them left and right, a trick he must have learned from Itachi, making the shuriken come back towards the blond at every turn. As he continued dodging, Naruto realized he was coming closer to the edge of the training grounds and that Sai was now on the offensive. Ink snakes slithered up all over his body, holding his feet firmly to the ground and effectively immobilizing him just as Sakura charged at him, her right fist raised and poised for one hell of a punch. Naruto quickly tore off the snakes around his torso and arms, raising his own right arm when Sakura was a step away ...

A tremor shook the ground as Sakura's punch landed. Everyone winced at the force of the hit but were left flabbergasted when they opened their eyes and saw that Naruto had effortlessly caught her punch. That was impossible! No one had ever stopped either Tsunade's or Sakura's punch! The looks on their faces must have made their thoughts more than obvious to the immortal because Naruto chuckled at them.

"We Uzumaki have wonderful natural chakra control. Most of the time we don't even need to train to be able to channel our chakra into punches and kicks." He channels his chakra into his feet and Sai's snakes burst into pools of ink on the ground as he took a step forward, pushing Sakura back. "Not to mention I grew up around Tsunade-baa-chan. When I was eleven, she finally agreed to show me what her own mother, Uzumaki Miko, had taught her. When I became an Immortal, I could stop her own punches unless she was really pissed."

The shinobi all shivered at the thought of a really, really pissed off Godaime but their attention was brought back to the fight when Naruto grabbed Sakura's still outstretched arm with his other hand and threw her over his shoulder. She barely caught herself before she hit a tree and prepared for further battle just as Sai lunged for Naruto. The black haired dormer Root agent was good at maneuvering kicks and hits but Naruto had many more years of practice than him. It was intense and fast, almost to the point that they were only a blur to the normal eye. Sai would drop to the floor and try to kick Naruto's feet from under him but the blond would jump up high into the air, landing behind Sai and kick him to the side while the pale teen was trying to get out of the way. Sai would then send his drawn lions at the Immortal but that's when Naruto decided to make things more interesting.

"Kage Bunshin no Jutsu!" He said while making a single hand seal, a cross like position while dodging the attacks of the ink lions. With a popping sound, three more Narutos appeared, two tackling the lions while the third took hold of the original's hand and threw him at Sai.

"Katon: Gokakyo no Jutsu!" But before Naruto could reach his target, a fireball nearly nailed him, making him change his direction and come to a stop. He looked over to Sasuke, who was making another series of hand seals but he was distracted from his charge by a war cry from above him.

"Channaro!" Sakura yelled as she made to punch the blond from above but Naruto got out of the way at the last minute. The ground now looked as though a meteor had struck it where the kunoichi had punched and Naruto had to hand it to her. Had that hit him, he would be sporting more than a few broken bones, ribs and maybe his spine, too. He looked over to his side when he heard a roar and cursed when an ink tiger charged at him as though he were fresh meat.

'This has gone on long enough,' he thought and called upon a few more Kage Bunshin to distract the two. He heard an all too familiar sound that resembled the chirping of a thousand dying birds and looked to his left to see Sasuke charging at him with the Chidori in his left hand, his red eyes making him look almost demonic in the light of his attack. 'I guess I have no choice.' He turned around swiftly as a mass of chakra started appearing in his hand, swirling around and around quickly to form a ball of pure energy. He thrust his hand forwards just as Sasuke lifted his hand-

Only for the sixteen year old to disappear from in front of him. Naruto didn't even need to look behind himself as he lifted his left hand, also sporting the spiraling ball of chakra to know that Sasuke had reappeared, ready to use the Chidori on his turned back. Sasuke's eyes widened as their attacks clashed, sending the airborne Uchiha back across the training grounds with a giant BOOM while Naruto held in place by using chakra in his feet to keep him rooted in place. The explosion from the collision of their attacks was first as black as space but then it turned so bright that everyone had to shield their eyes. When the light died down and it was safe to look again, Kiba let out an impressed whistle.

"Damn, that was one hell of a clash!" He said excitedly as they all stared at the smoke from where the explosion had taken off a good chunk of earth from the ground and had burned a lot of grass. Naruto had remained in his place and now stood on a lone pillar of earth with a little grass on his feet while a crater surrounded him. Sasuke sat up from where he was flung by the attack, rubbing his head and neck as he looked up and froze. Naruto was glaring at him.

"Never, ever, ever allow Chidori and Rasengan to clash." He warned in a grave tone. "Had I used my full power, both of us could have lost an arm!" Sasuke looked down at his arm and paled at the burns already present. He hadn't gotten such burns from the Chidori since he was first learning the technique. If he didn't get this treated, he could lose all feeling in his arm from the elbow down to his fingertips.

The blond soon had to spin around as Sakura and Sai attacked together, a tanto in hand for them each. Naruto took out two kunai and started defending himself, cursing the little ground he had. He jumped off of the pillar and threw his kunai at Sakura and Sai, pulling out a scroll and summoning a big shuriken out of it. He sent it flying at Sai while he met Sakura halfway for a bit of hand to hand combat. The girl had a lot of skill and she used her smaller figure to her advantage perfectly. She had speed but she didn't have Naruto's experience, especially not with speedy fighters. Every Uchiha was extremely fast because they had to do a lot of body activation exercises so their body doesn't force itself to catch up to the speed of their Sharingan and end up hurting themselves. Naruto had to be the one to help them with this sort of training and after four hundred years of such training, of sparing with such fast opponents, not even Lee or Gai could catch him off guard. Sakura wasn't nearly as fast as an Uchiha. He could easily dodge or block all of her attacks and he was stronger than her, even when she molded all of her chakra into a single hit.

Sai soon joined her in fighting him, having snuck up on Naruto from behind but Naruto had sensed him. He was not only a sensory type and had Kurama's heightened senses, but he was also the guy who lived with mischievous young ninja for four hundred years. The Uchiha started training their kids young and the first thing any of them learned was stealth. The Uchiha Clan always had enemies and they wanted their kids to be able to defend themselves or sneak away unnoticed should there be a fight that the adults could lose control of. They, of course, more often than not, used their newly learned skills to try and sneak up on Naruto at every opportunity. After the first three generations that he taught, Naruto got used to it and his body reacted on its own whenever a presence appeared behind him. As such, he got the first hit on Sai but between him and Sakura, Naruto knew he wouldn't be able to keep this up forever. They'd land a hit or find an opening to his vital points and if that happened, then the spar will be over and in their favor. Deciding he needed to end this - for Sasuke's sake, too. He had a nasty burn that needed to be looked at and fast - Naruto channeled some chakra around himself and flung the two younger Immortals back, to the opposite sides of the crater. He quickly made four Kage Bunshin and sent them to guard Sai and Sakura, two each. They were going to point kunai at their necks to show they were 'dead' so they could end the spar.

However, before the second clone could place his kunai besides Sakura's neck, it screamed in pain as black flames suddenly engulfed it. The flames quickly spread to the other clone and made to spread on to Sakura - who was staring in wide eyed fear, completely paralyzed - had Naruto not reacted in time. He flung one of those strange kunai right beside her head and one in the spot he was currently standing before disappearing with a brief flash of yellow. He appeared beside the pink haired girl and disappeared again, returning to his original place and watching as the earth there caught fire along with his kunai.

"What's going on?!" A panicked Tenten screamed as the flames continued spreading all over the earth, closing off the three teens in the crater. Kiba made to lung for their friends to help them but Neji tackled him to the ground.

"Let go of me, damn it! They need help!" The dog lover screamed at the Byakugan genius and Neji pressed down harder on him when he began struggling with vigor.

"We can't help them! We don't even know what's going on!" The long haired brunet yelled at the Inuzuka. "If we go in now, we'll only be a burden to Naruto-sama!"

"We need t-to trust that Naruto-kun will be able to keep things under control." Hinata said to the others even as she tried to see through the raging black flames. She was visibly shaken and afraid for their new friends but she knew there was nothing they could do. It was up to Naruto and maybe Sas- "Neji-nii-san, where's Sasuke-kun?!"

"You can't see him?" The incredulous older Hyuuga asked as he finally got off of Kiba. When his cousin shook her head, he closed his eyes before snapping them open. "Byakugan!" His vision suddenly became black and white and he could see in a circle, all around himself. But he couldn't see anything beyond the black flames, not even his friends' chakra signatures. "I don't see him either. In fact, I can't see anything because of this fire!"

"Kiba-kun, can you smell them?" Lee asked as he stared worriedly down at the fire. The Inuzuka shook his head, chewing on his lip. "There has to be something we can do!"

"We won't have to. Why?" Shino speaking up surprised them but they followed his line of sight when he pointed a finger towards the left side of the crater. "Because Naruto saved them."

"On thank Kami!" Tenten breathed in relief and Akamaru barked excitedly. "Well, I guess we should start dealing with the fire. I have a sealed water dragon here," she said as she reached for a scroll containing said dragon, only to yelp in shock when a tanned hand stopped her.

"Don't throw anything at the flames!" A slightly singed Naruto ordered as he put Sakura and Sai down. He was glowing like the sun and had been carrying the two younger Immortals in two of his nine chakra hands that fanned out behind him like a peacock's tail. His entire being was as gold as his chakra and his eyes were red with a cross like pupil as he stared out at the fire. His clothes were marked with strange black designs, as were his whisker scars painted with it while the tails of his hitai-ate stool out almost like fox ears. "You'll just spread the fire! Don't move from here!" And he was gone again before anyone could react.

Naruro found himself where he had seen Sasuke last before taking Sai and Sakura away. The boy was clutching at his eyes and temple, doubled over on his knees, letting out a scream of pain every now and then. The black flames had spread a great deal by now and the Immortal knew this had to be stopped before the flames reached the houses. Sasuke will never forgive himself if he accidentally destroyed the only remains of his clan and family, even if it was by accident.

"Sasuke!" He called out as he knelt besides the Uchiha. "Sasuke, snap out of it!" He shook him by the shoulders, trying to bring him out of his pain. Nothing but the ignitor of these flames can stop them. They were already out of control enough to burn down the whole of New Konoha and there is now way it will stop there. Tokyo and then the roads and fields around the megalopolis will catch fire and so on until nothing was left to burn. "SASUKE!"

"It hurts," the raven finally uttered and Naruto sighed in relief. He was back.

"Sasuke, you need to stop this and fast!" He yelled over the roaring black fire. It was only a few feet away and they were going to die if they didn't get out of here.

"I can't! I don't know how! I don't know how it even started! My eyes just started hurting-"

"We don't have the time for that, teme," Naruto said as he rightened Sasuke up, letting the taller teen lean against him. "And yes, you can stop this! These flames are yours to control!"

"How!?" The panicking teen demanded, still not letting go of his eyes. He was positively terrified! He had just reacted to seeing Sakura's life seemingly in danger. He wasn't even aware of what had happened until his eyes started burning so much that he wanted to pry them out of their sockets and squash them with his own hands if it was going to stop the pain!

A cool hand settled over his own hands and gently pried them off of his face but Sasuke refused to open his eyes. "You need to look at them and will them to stop, to go away. This is just a product of your Sharingan, Sasuke." The words were whispered soothingly in his ear and Sasuke ft himself relaxing with each syllable that left his supposed guardian's lips and entered his ear. "It's under your control. Only you can stop these flames. Hurry."

When he felt the heat getting too close, Sasuke opened his eyes and was greeted with a giant wall of black fire, menacingly towering over him and the blond who hadn't moved from the moment he had gotten to Sasuke's side. He was kneeling between Sasuke and the fire, glowing like a beacon and chakra spanned out around him in an attempt to keep Sasuke and himself safe. Red eyes widened when they met the equally bloody red eyes of the Uchiha before Sasuke looked over the blond's shoulder, through the cracks of the protective chakra hands, directly at the black flames. He stared at them, feeling like they were drawing him in until he heard Naruto hiss when one flame licked his chakra hands and Sasuke snapped back to himself. He glared at the flames and they seemed to gain a second wind before hastily disappearing, leaving not a trace behind.

Sasuke looked back at Naruto and noted how singed the other looked, feeling guilty until a bout of vertigo hit him and he nearly collapsed had his companion not caught him. "Oi, don't faint on me!"

"Tch, I'm not weak, dobe. I'll be fine," he grumbled as he clutched at his head. Damn, but his eyes were stinging like someone had pocked at them with a toothpick until they bled. In fact, what was that warm, sticky substance rolling down his face? He touched it with his fingers and brought it before his eyes. His vision was blurry but he knew it was blood. "Did I hit my head or something?" Suddenly, a cloth was covering his eyes, rendering him blind. "Hey, what's the big idea!?" He asked as he heard cheering in the distance.

"Teme, you big idiotic teme!" The blond scoldingly grumbled as he tied his hitai-ate around the mortal's eyes. "You're eyes are overused enough as it is! You need to rest after using Amaterasu like that!"

"Amaterasu?" He was getting dizzy again. He knew he must be leaning against Naruto, but he was losing focus and consciousness pretty fast that he couldn't really be sure. He had already lost control of his body. He was only half aware that he was still sitting up so he must be propped up by something and only Naruto was nearby.

"I told you you weren't even aware of how developed your Sharingan is, Sasuke." The blond's words sounded so far away. "You have the Mangekyo Sharingan."

"Mangekyo ... Sharingan ..." And then everything went black.
