Sharingan Fairy

Summary: Once upon a time, his mother told him the tale of the Sharingan fairy, who would gift the Uchiha with their doujutsu in times of great need. After he lost everything that fateful night, he has all but forgotten about her. But when his classmates show worrying signs of possessing the Sharingan, Sasuke has no choice but to figure out why the hell she has decided to visit all of them.

Answer to Ser Serendipity's challenge.

Disclaimer: I don't own Naruto and the story premise belongs to Ser Serendipity.

"Kaa-san? Where does the Sharingan come from?" one young Uchiha Sasuke asked, dark eyes wide with curiosity.

This question had really started to bother him ever since he had seen Itachi's weird version of the Sharingan after his confrontation with the other police officers.

"Oh? Wouldn't you like to know? I'm afraid only those who have the Sharingan are allowed to know," Mikoto said teasingly, poking her son's nose.

"Kaa-san," Sasuke whined as he rubbed the red spot on his nose. It made him wonder sometimes if Itachi got this annoying poking habit from their mother.

Seeing her son's adorable pout, Mikoto relented with a laugh. "Okay, but you must swear that you won't tell anyone. Understood, Sasuke-kun?"

"Yeah. I won't tell anyone. I promise," Sasuke said as solemnly as a kid his age could.

His mother smiled warmly at him as she told him of the great Uchiha secret.

"There's a very caring and kind being called the 'Sharingan fairy'-"

"Is it like the tooth fairy?" Sasuke interrupted, somewhat disappointed by the idea that they got their awesome kekkei genkai thanks to some sparkling, glittering butterfly thing. He had expected something way cooler like Itachi-cool.

Mikoto looked upset by the interruption so he quickly apologized. He didn't want to be scolded after all and he did want to know about the big Sharingan secret, even if it started to sound really boring and girly.

He knew for a fact that the Sharingan itself wasn't. Quite the opposite in fact. Apparently, it was the best thing since sliced bread. His father had said so (although, admittedly, he had worded it differently), Shisui had said so (whom he was quoting), every other Uchiha had said so and his brother Itachi had sort of implied it, which totally counted too.

So Sasuke was relieved when his mother accepted his apology gracefully.

"As I was saying, the Sharingan fairy is kind and loves the Uchiha clan dearly because one of our ancestors had once helped her. As a sign of gratitude, she gifts each of the Uchiha children with the Sharingan when they get into trouble."

"So I just have to get into trouble and I get really strong, right?" Sasuke asked, his mind quickly making the connection.

His mother frowned. "It doesn't quite work this way, Sasuke," she said. The fact that she dropped the '-kun' suffix made it pretty clear that she was serious. "If you want to get into trouble, the Sharingan fairy will know and she will erase one of your golden stars," she warned him.

"Golden stars?" Sasuke echoed, confused.

"Yes, every child has thirteen golden stars and the Sharingan fairy takes one away whenever they deliberately get into trouble. If you don't have any stars anymore, the Sharingan fairy won't give you the Sharingan at all. However, if you still have all of them at the end, once you get the Sharingan, they will be very strong," she explained, only barely resisting the urge to chuckle.

Sasuke looked positively awed. "So that's why Itachi is so strong. He still has all of his golden stars!"

"Yes, he does. He never got into any sort of trouble," Mikoto confirmed, smiling a little.

"But Itachi was being mean to those officers and otou-san and he threw a kunai at that stone wall. There's still the crack and you always tell me that it's bad to break something," Sasuke argued, frowning.

"Ah, he has lost some golden stars but not so many that the Sharingan fairy would take his Sharingan away again," Mikoto smoothly talked her way out.

"But he's weaker now so that means that if I'm behaving really nice, I'll get so much stronger than him. Awesome!" Sasuke exclaimed excitedly before he ran out of the room, setting out to do whatever it was that counted as 'behaving really nice' in his mind.

Mikoto sighed. For some reason, she felt like she had just made a huge mistake.

o.O.o

Her regret didn't last long, however, since she was killed a week later after she had told her youngest son about the Sharingan fairy. For that matter, the rest of the clan couldn't regret very much either now as they were all sort of dead.

Some streets further away from his mother's corpse, one Sasuke glared hatefully at his murdering brother, unaware of the fact that the Sharingan fairy had apparently decided that 'having your entire clan killed by your brother and then having to witness all of it because of some twisted genjutsu' counted as getting into trouble and thus had decided to gift him.

"The Sharingan fairy will take your eyes for this!" he shouted, dramatically pointing his finger at Itachi's crying face before he fell unconscious.

Itachi blinked thrice before he approached his little brother's prone body and carefully picked him up. Perhaps, his Tsukuyomi had been too strong, he mused worriedly as he raced to the Konoha Hospital.

o.O.o

"What the hell are you doing?" Sasuke demanded to know. He had sneaked out of the hospital room to confirm whether he had really seen Itachi murder their entire clan in cold blood, only to be greeted by the sight of masked ninja sneaking around in the clan compound.

Sasuke couldn't tell what the masked ninja, who were most likely ANBU like his bro- that man used to be, were thinking as they exchanged looks. Never mind that he had no clue how that worked with them wearing, well, masks either.

But they were still Konoha nin so he wasn't too worried that they would harm him. What was worrying though was the fact that they were putting his clan's corpses into those weird scrolls.

Dimly, he could recall that Iruka-sensei had once told him that this process was called 'sealing'. Before he could ask why the ANBU was sealing his clan away, an ANBU suddenly materialized right before him.

One hand seal later and he was out cold again.

"We should inform Danzo-sama of this," one ROOT ninja said. If the ROOT weren't trained to have the emotional variety of a stone, someone would have said 'duh' and face-palmed. As it was, the ROOT ninja's looks only became blander. Somehow, said ROOT ninja noticed this and if he could, he would have blushed.

He couldn't though so his look only became blander instead. Despite the mask, his fellow ROOT members noticed this too.

Sasuke, however, would never realize that he had been running to the clan compound not one but two times to confirm whether what would be later simply known as the 'Uchiha Massacre' had truly happened.

o.O.o

A week after the tragedy, no further clans were killed. However, Danzo looked smug which was just as bad as the near total eradication of an old and powerful clan by one of its own.

Hiruzen was appropriately wary as said smug Danzo entered his office.

"What is it, my old friend?" he asked, trying and failing to smile amicably.

"I have found a way to perform a surgical procedure that allows finer control of implanted Sharingan. As opposed to Kakashi, those ninja, who have received the implanted Sharingan, would be able to deactivate it," Danzo said, cutting right to the chase.

"I see. Is there a specific reason why you are telling me this?" the old Hokage asked. He would bet his entire stack of porn on the fact that it had something to do with the tragedy which had befallen the Uchiha clan a week ago.

He wasn't disappointed as his old rival said, "I, coincidentally, happen to be in the possession of approximately two dozen Sharingan."

"Coincidentally," Hiruzen repeated, disbelieving.

"Indeed," Danzo confirmed, his face as blank as the ROOT ninja he controlled.

Hiruzen sighed. He didn't really agree with his old friend and rival, which wasn't anything new really, but with such a potentially very strong weapon at their disposal, it was hard to simply dismiss it..

"How exactly would this surgery work? And is there any risk for the shinobi who undergo this procedure?" he inquired.

"It would work best on children, the younger the better. In addition, while it is of no importance, this method of implanting the Sharingan also allows the children to keep their original eye color and shape. I suppose it would be convenient for some of them," Danzo explained.

Hiruzen was going to regret this, he just knew it.

Against his better judgment, he said, "Fine. I'll allow the surgery on Academy children whose parents are willing to have their children partake in this. However, Danzo," at this, his eyes hardened, "you will take full responsibility if one of these children gets hurt."

"I understand, Hokage-sama."

The fact that Danzo addressed him so respectfully only made his bad feeling grow worse.

o.O.o

"My eyes are itching. How troublesome," Shikamaru complained. Now, he wouldn't be able to take a nap. Troublesome.

o.O.o

"My eyes are itching. It's so annoying," Kiba whined. Akamaru, who was laying on his lap, barked sympathetically at his plight.

Hana raised an eyebrow at her little brother who looked ready to scratch his own eyes out. It couldn't be…

"I really hope you don't have the same dog allergy like our father."

"What?!" Kiba shouted, horrified, Akamaru, leaping out of Kiba's lap and barking just as horrified.

o.O.o

"My eyes are twitching," Choji told Ino, who had come to visit him, since their families tended to come together once a week. Shikamaru, unfortunately, had been sick for the past days so he wasn't around for Choji to talk to.

"Maybe, you shouldn't eat so many chips and then rub your eyes with those dirty fingers," the blonde said, berating him. She wrinkled her nose.

Choji sighed. He kinda missed his lazy friend.

o.O.o

Ino frowned at her reflection. Her eyes were red because she had been rubbing them nonstop. She didn't want to but they were itching. Badly.

In one hour, she had to go to the Academy where she would meet Sasuke-kun and here she was, looking like she had cried herself to sleep last night. Great.

Maybe, she could convince her parents to allow her to use makeup to cover this up just this one time. Her parents had always said no, because she was apparently too young to try out something like makeup but this was an emergency. No way was she going to leave the house with a face like this.

o.O.o

Shino was currently facing a dilemma.

Why?

Because his eyes were itching and he wore sunglasses like a proper Aburame.

However, for him to rub his eyes, which would most likely feel absolutely blissful, he would have to take off his sunglasses. And for an Aburame, taking off his sunglasses in public was the same thing as taking off his mask was for Kakashi.

It was just not done.

Maybe, if he was getting very desperate, he could make his insects, which his father had finally allowed him to use for real last month, do something against this itching.

o.O.o

"No! I won't let you implant the Sharingan into Naruto's eyes," Hiruzen said angrily. "Who knows what is going to happen if he has the Sharingan and the Kyuubi chakra combined."

"Hokage," Danzo said calmly in the face of Sarutobi's anger. "I have made sure that the Sharingan will not have any negative effect on Uzumaki or interfere with the Kyuubi's chakra in any way that could harm the boy. However, consider the fact that with a Sharingan at his disposal he would have a much easier time controlling the bijuu in the future."

"Are you absolutely sure?" Hiruzen demanded to know. He had already failed Naruto many times before and he didn't want to be responsible for something which could potentially be his greatest failure in regards to Minato's son.

"Yes, I am," Danzo said, no shred of doubt betraying his statement.

Shoulders slumped and praying that he wasn't about to make one huge mistake, he reluctantly said, "Fine. You have my permission. Tonight, you will be accompanied by ANBU to oversee the surgery on Naruto."

It was for the best, Hiruzen tried to convince himself as he watched Danzo leave.

o.O.o

Some people complained. Some worried. However, in the end, everyone agreed, albeit some did so rather reluctantly, that each of the chosen kids would be allowed to keep their Sharingan.

Luckily, it was Danzo who had been forced to negotiate with the unhappy villagers, who had all gotten wind of the fact that there were currently a bunch of children, among them being the Kyuubi jinchuuriki, running around in the village with their newly acquired kekkei genkai.

As far as Hiruzen was concerned, he considered it a small blessing.

o.O.o

Sasuke didn't know why and he didn't know how, except he did. He knew why his classmates (and even the dead last Naruto!) were suddenly all parading around with the Sharingan, something that even he, as the last Uchiha (and that man didn't count), had not been able to unlock yet.

It was the Sharingan fairy's fault!

As the last Uchiha, it was his duty to find out where she was and ask her for answers only she would be able to give.

It was too bad really that his mother or any Uchiha for this matter, who could have told him more about the Sharingan fairy, was, well, dead. However, something like this wouldn't, couldn't deter him.

He would discover her secrets, he swore with just as much vehemence as he did, whenever he swore to kill that man and resurrect his clan, which was quite an impressive amount as it so happened.

However, first of all he had to prevent the other kids from getting more powerful with the Sharingan, which by all rights belong to him and his clan.

Luckily, he still remembered what his mother had told him. He was so going to make them lose their golden stars.

o.O.o

"Can you think of any reason for Sasuke's sudden shift in personality?" Hiruzen asked a twitching Iruka, who had told him of this worrying bit of latest news regarding the students' development, especially the one of a certain student.

"No, I can't," Iruka said, frowning. "For all appearances, it looks as if this change has happened out of the blue."

It was more than worrisome for Sasuke, who had chosen to push people away and utterly focus on his goal of killing his brother, to suddenly do a 180 and try to get himself and his classmates into trouble.

Yesterday, he had even overheard Sasuke asking Naruto for advice on how to best get into trouble, who had then promptly decided to give him a demonstration. This, unfortunately, had resulted in half of the teaching staff finding out firsthand how it felt to be like Haruno Sakura or to put it more bluntly, discover that pink hair really only suited cute, little girls.

"What do you propose then?" the Hokage inquired, steepling his fingers.

"Well, I haven't really talked to Sasuke yet so I suppose that this is going to be the first thing I will do at school tomorrow. Depending on his answer, it will either turn out to be Sasuke's way of dealing with his loss, in which case I will try my best to help him get past his grief, or it's something else entirely and I will just have to see how I can support him best."

He sighed. It wasn't the best way but he really had no clue how he should approach his student. Unlike Naruto, he didn't allow anyone to get close to him.

"I suppose that this will have to do," the Hokage agreed, looking every bit his age now. "Please inform me once you find out the reason for Sasuke's behavior."

"Of course, Hokage-sama."

o.O.o

"Come, dobe," Sasuke hissed as he dragged Naruto further away from the other kids who were all currently enjoying lunch break.

"Are we going to prank someone again?" Naruto asked, his expression immediately brightening up.

Sasuke only smirked in response. This was going better than he had initially hoped for it to go. At this rate, the dobe was going to lose his Sharingan tomorrow or so. Then he could finally stop trying to drag them both into trouble.

He frowned as a sudden thought occurred to him. It wasn't only Naruto himself, who had caused a lot of trouble. He too had been responsible most of the times and maybe even more so than the blond because, unlike the dobe, he had also helped other students with their own mischief.

Sasuke's already pale skin turned paper-white when he realized what this actually meant for him.

He was never going to get the Sharingan.

o.O.o

"Iruka-sensei!" Naruto yelled as he raced to his teacher, pushing several students out of the way in the process.

"What is it?" Iruka asked worriedly. He knew from experience that something horrible must have happened or was bound to happen, when Naruto, out of all people, was the one running to the teacher.

Great, just when he had been about to go to Sasuke and have a nice little chat with him.

"It's about Sasuke!" Naruto shouted, confirming his worst suspicions. "He suddenly turned all white and hasn't moved a bit for like hours and I poked and tickled him and he still won't move him!"

The scarred Chunin knew that Naruto was probably exaggerating but it didn't change the fact that whatever it was that had changed the Uchiha couldn't be anything good, if his current behavior was any indication at all.

"Show me where he is," he said and his student hurried to do as he was told for once. Apparently, Naruto cared more for Sasuke than he had initially expected.

o.O.o

"Oh, having the Shaganrin is so awesome," Kiba exclaimed excitedly as he watched a spar unfolding before him with his Sharingan, three tomoes whirling in each of them. He knew that he would feel really tired afterwards but this was totally worth it.

"Sharingan," Shino quietly corrected, adjusting his sunglasses that slightly hindered the visual capability of his already matured Sharingan.

"Whatever. With Akamaru at my side and the Shaganin, no one is going to stop us!" Kiba declared, a clenched fist held over his chest.

Akamaru gave him the dog equivalent of a 'Hell yeah!'

"Sharingan."

"Shut up."

A/N: The reason why neither Sakura, Hinata, Rock Lee, Tenten nor Neji got a Sharingan is because they do not come from prominent shinobi clans and also, because they didn't show any outstanding potential yet so Danzo wouldn't bother wasting the eyes on them, and the two Hyuuga aren't affected because they already have their own doujutsu.

I'm also not sure if I will continue this as I'm already occupied with writing my other Naruto fic, 'But I AM Madara!' so it's going to be an one-shot for now. However, if I get some more inspiration regarding this story, I will make sure to continue it.

Feedback is greatly appreciated :)
