Haru: Born in the spring.

Chapter One

"I don't believe it. Konzo, are you seeing what I'm seeing?" A criminal ninja says, just a few miles out side the Leaf Village.

"That kid has the Sharingan and the Byakugan! He's gotta be worth a fortune and he's all alone!" Konzo replies to his partner, Kenshin.

Haru looks around warily. His mother and father had warned him this might happen one day. Sasuke had said that there was a ninja who had been attempting to use a Forbidden Time Jutsu and that Haru was going to get sucked into it.

This man wanted to go back in time to try to take over the world. But he was foolish. He didn't have enough chakra to do it and he would die in the attempt of chakra exhaustion. Haru had just happened to be nearby and got sucked into the portal. It wasn't that he was trying to go back in time, it was just dumb luck.

"Mother and father will still love me." He mumbles to himself, trying to reassure himself that would indeed be the case.

"A parent's love is instinctive. It knows no boundaries, not even time itself. We might know you in the past, but we will love you. Please do not be upset. Your father and I…took awhile to notice each other. We might not be together in the past. But we will fall in love because of you." She had told him with a smile.

"Hey, kid…you lost? Want us to help you find your mommy and daddy?" Konzo asks in what he thought was a friendly tone.

Haru's eyes narrow. He'd seen that look before. People always wanted his eyes.

That's why his mother said never to talk to strangers. He decides to ignore him for now. This man was nothing but a common criminal. As his father would say, not fit to wipe the dirt off his sandals.

"Guess the kid is a bit shy. It's alright. We won't hurt you." Kenshin tells him.

"It's not nice to lie. I know you want my eyes. You can't have them though." Haru says with more authority and a certain regal demeanor that no five year old should possess.

He was descended from two Noble Clans. He wasn't going to be intimidated by a couple of bullies. If they tried to touch him, he'd use his fireball jutsu on them. That would teach them to leave kids alone!

"Smart kid. Oh well. I was going to try to do this the nice way. But you leave me with no choice." Kenshin says.

Haru smiles. He could sense his father's chakra nearby. Father would always protect him. These mean men were in BIG TROUBLE.

Haru deactivates his eyes. He didn't need the Sharingan and Byakugan on now to protect him. Sasuke would be here soon. Besides, he needed time to explain. If anyone in the Leaf saw his eyes, he'd be separated from his father before he could.

That's when the criminals made the mistake of lunging at boy with kunais drawn, clearly intent on cutting his eyes out. A black, white, and blue blur flits out of nowhere and slams them into the ground long before the man got to Haru. The youngest Uchiha couldn't resist sticking out his tongue at his attackers. Thankfully his "father" had his back to him. So Sasuke didn't see it.

"It's hard to sink lower than attacking some lost kid. I'd kill you but you aren't worth the effort. Go before I change my mind." Sasuke says.

"Is that Sasuke Uchiha?" Konzo asks.

"Yes, we better run!" Kenshin answers and the men take off running for their lives.

"You aren't hurt, are you?" Sasuke asks the kid.

He didn't know what came over him. Sasuke knew that he would have helped any kid in that situation. But this felt…different.

He felt like he had to protect this boy, no matter what. He had wanted to tear those men to shreds with a ferocity that stunned him. Sasuke wasn't sure why he felt that way. The last Uchiha just knew that he did.

"I'm okay. Thank you for saving me." He says with a serene smile.

He tilts his head and takes the time to observe the kid. He didn't look hurt. If Sasuke had to guess, he'd say he was probably around 5, maybe 6 years old. Cute kid. Adorable really. Adorable was NOT a word that was generally in Sasuke's vocabulary, but it was accurate in this case.

He was tall for his age. His hair was regal shade of midnight blue and styled like Sasuke's had been once upon a time, when he was still innocent. His skin was an ivory cream color, almost identical to his own. Perhaps one shade darker.

His eyes were an exotic combination of lavender and silver…Hyuga eyes, Sasuke mused. No wonder the bandits had been targeting him. There was a big black market for eyes like that.

"Let's get you back to the Hyuga Estate. Your parents must be very worried about you." Sasuke says.

So why, other than his coloration did the kid look so much like him? This kid was clearly a Hyuga. But there was so much Uchiha in him. It was like looking at an old picture of himself as a small child. Sasuke was torn between being intrigued, disturbed, or pawning it off to a very odd coincidence.

"Alright." He agrees and walks off with Sasuke.

Did Itachi have a child with a Hyuga before he died? No, that couldn't be it. The timeline didn't add up.

Nevermind, Itachi had been so sick at the end of his life. Even if he wanted to, Sasuke found it highly unlikely Itachi would have been able to sire any children. Let alone the healthy boy that stood before him.

Something was going on here. That kid wasn't scared at all. Those men had tried to cut his eyes out. Yet he was smiling and as calm as could be. Like he didn't have a care in the world.

He seemed to trust Sasuke implicitly. Well Sasuke had saved him, but still there should be some natural wariness of a stranger. Who was this kid?

"What's your name?" Sasuke asks.

"Haru." He answers.

"Haru Hyuga. Hyugas do love their alliteration." He muses, thinking of Hinata and her younger sister.

"Oh my last name isn't Hyuga." He says cheerfully.

Sasuke blinks. The kid had to be kidding him right? Those eyes screamed HYUGA.

"But you didn't argue when I suggested we take you to the Hyuga Estate." He says.

"No reason to. That's where my mother's family lives." He replies with a smile.

"So…your father isn't a Hyuga then?" He asks.

"No." He states honestly.

"That's rare. The Hyugas are rather strict about marrying inside the clan to keep the Byakugan pure." Sasuke observes.

Sasuke had never been to the Hyuga Estate before. It was like a palace or a tomb. Everything was so beautiful, but so utterly sterile.

The place was eerily quiet. He could see some Hyugas doing work in the fields, but only a handful of words were exchanged. They reminded him of bees in a hive. He pushes back his unease and knocks on the door.

Hiashi answers it. He raises an eyebrow. What on Earth was Sasuke Uchiha doing here?!

"I found this boy. Some bandits were attacking him. He says his mother is a Hyuga and judging by his eyes, I'd say he's telling the truth." Sasuke summarizes.

"His eyes are from my clan. But I do not recognize him. I know every member of my clan. Who are you boy?" Hiashi asks and looks at him suspiciously.

Haru wanted to say, "I'm your grandson." But he knew that wasn't a wise idea. He had to come up with something and quick.

"I'm Haru." He says with a friendly smile.

"And who are your parents? You look Hyuga. But as I said, I do not recognize you." He states.

"Um…mother and father are kinda busy right now!" He replies, avoiding the question.

"I want to take this child to get tested. Something very strange is going on." The Hyuga Patriarch states.

"Alright. But stop looking at him like that. He's just a child and doesn't need to be glared at." Sasuke says.

"I never would have thought you the sort to have a soft spot for children." The older man muses.

"I'm just full of surprises." Sasuke says sarcastically.

"Indeed. Good day, Uchiha. This is a FAMILY affair." Hiashi says in a dismissive voice that made Sasuke's blood boil.

It wasn't his business though. The kid was clearly a Hyuga. He'd taken Haru to the Hyuga Estate. They'd figure it out.

"Please don't go!" Haru says and clings to his father's leg.

"It's alright. He's not going to hurt you." Sasuke says, leans down until he was eyelevel with the kid, and Hiashi finds himself surprised by the kind expression in the Uchiha's eyes.

Sasuke Uchiha was a force of nature. A very destructive force of nature. He certainly did not smile or look at anyone softly. What in the world was going on here? Had the world gone mad?

"Alright." Haru says.

"Good." Sasuke states and heads off.

"Come, boy. We are taking you to the hospital to get to the bottom of this." Hiashi commands and starts off.

A few minutes later, Hiashi looks back. The boy wasn't following him. Was the boy simple? Did he sincerely not understand the very clear order to follow him?

"Boy, I told you to follow me. Why are you not doing as I instructed?" He demands.

"My name isn't boy. It is Haru." The child states and Hiashi raises an eyebrow.

Normally, he might pawn this off to genuine confusion on the part of a child. The kid might not understand that boy was meant to address him in a general sense. But there was a pride in the boy's eyes. A determination to prove himself. No, the boy had understood him perfectly and chosen to defy him.

The brat actually wanted to be addressed by his name as if they were equals. Laughable. Though Hiashi was impressed that such a young child had what commoners referred to as "balls."

"One of your parents is not a Hyuga. A full blooded Hyuga would know not to question their elders and show such disrespect." He states.

"My father isn't a Hyuga." Haru admits.

"I thought as much. Perhaps you are the product of an affair. I have no idea how you stayed hidden so long. Come…Haru." He says and the child obediently follows him.

"I want this child to under a paternity test immediately." Hiashi says as he enters the Leaf Hospital.

"Of course. Though…it's kinda obvious he's a Hyuga. Look at those eyes." Sakura says.

"I know he's a Hyuga! But the boy won't tell me who his parents are. He has admitted that his father is not from our clan though." Hiashi states.

"Alright. This should take more than a couple minutes. Please come with me." She says, smiling at Haru.

"Okay." He says and follows Sakura, mostly because he knew that the paternity test results would help bring his mother and father to him.

He recognized Sakura. It was hard not to. Her pink hair was very distinctive. She had been on his father's team. She could be trusted, he decided.

"Alright, a hair sample should be enough. If we don't get conclusive results, then we'll go with a blood sample." Sakura says and then gasps, when she takes a closer look at the kid.

This child. He looked almost exactly like Sasuke did when he was at the Academy. His hair was a different color, yes. His eyes were definitely Hyuga eyes. But everything else was nearly identical.

"I don't mind if you have to do a blood test. I'm not scared of needles." He says with a smile.

That was impossible though. The boy sitting on the exam table had to be at least five years old. Sasuke would have had to get someone pregnant while he was still a Genin. He'd turned 19, only last month. The only way he could have sired a child this age was if he got someone pregnant immediately after going to the Sound.

"That's good. You are such a brave boy." She praises him.

She shivers. It was…technically possible. But she figured it was highly unlikely. If Sasuke did have a son, he wouldn't have just left him behind like that. Unless he didn't know about it.

"Mother says I take after father that way." Haru replies, clearly happy about the praise.

All sorts of horrible scenarios went through her head. What if Orochimaru or Kabuto had taken a sample of Sasuke's genetic material and used it to produce a child without Sasuke's knowledge?!

She manages to stop her hand from shaking long enough to get a strand of the child's hair and run the tests. While she was waiting, she decides it would be best to try to engage him in some conversation. Maybe she could find out what was really going on.

"What's your name?" Sakura finds herself asking.

"Haru." The boy answers.

"Well Haru, the results shouldn't take more than a couple minutes to be ready." She assures him.

"Does the beeping noise on the machine mean it's done?" He asks curiously.

"Oh yep! Good catch." She says and looks at the results and promptly fainted.

The results made no sense. Hinata Hyuga and Sasuke Uchiha were listed as the parents. But they were too young! Hell, they'd never even talked to each other as far as she knew.

"Sakura?" Haru asks and tries to wake her.

Haru might have been a prodigy. But he was really, still a five year old kid. He panicked and screamed his lungs out for help.

His shouts did the trick. Soon enough someone overhears him. He sighs in relief when he sees his mother. She was younger, but it was still her. It looked she had started her training to become a medical ninja already.

"What's wrong?" She asks and then blinks when she sees Sakura.

"She fainted!" Haru says.

"Yes, don't worry. It'll be alright." She tries to reassure the boy and checks Sakura's vitals, they were all stable.

Hinata concludes the other woman had just passed out from shock. But what could have shocked her so badly. Sakura was not easy to startle. She had fought during the War with distinction.

"Oh Hinata. I had the strangest dream. I was giving this boy a paternity test…"She mumbles.

"That wasn't a dream. The machine is on." Hinata says.

"But that's impossible!" She protests.

"Were the results really that shocking?" Hinata asks curiously and tilts her head innocent.

"The results say you are a mother!" Sakura says.

"Sakura, I think the machine must be malfunctioning. I think I would remember being pregnant." Hinata says with a giggle.

"I know! It has to be a mistake or maybe…would anyone have had access to your eggs?" Sakura asks.

"What?! Of course not!" Hinata blinks, suddenly more freaked out than amused.

"Then it has to be a mistake." Sakura says.

"And who did the machine say was the father?" The Hyuga heiress dares herself to ask.

"That's what makes this all so strange. Sasuke." The other medic answers.

"…" The bluenette was speechless.

Sasuke? Sasuke Uchiha?! She'd never even spoken to him. That machine had to be broken.

"Are you okay? Maybe you should sit down." She hears the child ask.

Hinata turns around. Suddenly, she was curious what her child looked like. She blinks.

Well if this was a prank, it was excellently executed. The boy had her hair and her eyes. But in every other way, he looked like Sasuke had at the Academy. He was fidgeting a bit though, doing her nervous hand gesture.

"I think you should run a few more tests, just to eliminate the possibility that it was a machin-e error." She stammers.

"Yeah. Good idea." Sakura says and decides to take blood tests from both of them.

"What's it say?" Hinata asks after a few minutes.

"It's another match. Um…I think we should probably get Sasuke here. Get Kakashi and Tsunade too. Tsunade should run the tests. She's more experienced than me. Maybe I'm just doing it wrong." Sakura suggests.

Hinata takes another look at the boy sitting on the table. She bites her lower lip. Somehow, she didn't think it was an error. The boy looking back at her with eyes that were the mirror image of her own.

Sakura calls for Kakashi, Tsunade, and Sasuke to come. Tsunade because she was the best medic alive. Kakashi because he was Hokage and he had been their Sensei. If anyone would know how to keep Sasuke calm, it would be him. Sasuke because well…he was possibly the father.

"So you are telling me that you think this boy, is Sasuke and Hinata's son?" Tsunade asks.

"I don't know! I ran several tests. They all came back with the same result. Maybe I'm doing it wrong. Maybe something is wrong with the machines." Sakura suggests.

"Do it." Sasuke says, offering her his arm to Tsunade take a blood sample.

"Well thank you for being so unexpectedly cooperative." Tsunade says and takes the sample.

"If he's my son, I want to know." Sasuke says.

"Of course. This is going to take a few minutes. I want to run this test at least three times on different machines, to remove any possibility of machine or human error." She states and the "parents" nod.

"This isn't possible though. For Sasuke and Hinata to be the biological parents, they would have had to have him when they were 12 or 13 years old. That boy is at least 5." Kakashi muses.

"…Apparently the impossible is possible. It's a match. I just tested it three times. They all matched." Tsunade says, completely stunned just a few minutes later.

Sasuke blinks. He couldn't believe it. But he couldn't argue with the results either. Looking at the kid, he couldn't believe his eyes.

Haru, as he called himself, looked so much like him. Yet, he could clearly see Hinata's influence. So that's what he meant when he said his father wasn't a Hyuga.

Sasuke darts behind Hinata. He fully expected her to faint. Hell HE felt a little lightheaded himself.

"Thank you but I'm alright. I th-ink." She mumbles, clearly recognizing that he had been about to catch her if she fainted.

"Well young man, perhaps you would like to start talking." Kakashi suggests kindly.

"If I tell you…you won't get mad?" Haru asks nervously.

"We won't get mad." Kakashi promises him.

"It was a Jutsu." He mumbles.

"What kind of jutsu?" Sakura asks.

"Time travel jutsu. There was a man. He was bad. But he was stupid. He didn't have enough chakra to power it. I got sucked into it. It's okay though. Mother and father said it happened before. That I'll go home soon." He finishes in a rush.

"Time travel? Is that even possible?" Sasuke asks Tsunade.

"There are several experimental jutsus in the works. But no one has ever actually managed it before. If what he says is true, maybe someone got closer than we have. Besides, we can't really argue with the DNA results." She answers him.

"What year is it, where you are from?" Kakashi asks.

"Um I don't know if I am supposed to say…" Haru mumbles.

"It's probably a bad idea to screw with the timeline like that." Sasuke defends his son.

"Well it seems like some screwing did take place." The Hokage says with a chuckle.

SMACK! Sasuke glowers at Kakashi, his Sharingan whirling. That pervert! How dare he talk like that when his son was present?!

"You pervert. Don't talk that way when my son is sitting right over there!" Sasuke growls.

"Parental instincts…are fully functional." Kakashi muses and nurses his bruised cheek.

Hinata blushes deeply at Kakashi's words. She looks at Sasuke. Then she looks at Haru. The test results had all come back as a match. Sasuke was the father of her child. Well he was going to be one day. But how?

Just because he was the father though, that didn't mean they were together in the future. Maybe it was a one night stand? She dismissed that thought as quickly as it came. Sasuke didn't seem the type to indulge in such behaviors and she definitely wasn't.

Maybe they had been on a mission or something? It had been known to happen, that ninjas would pose as lovers on undercover missions. That seemed…somewhat more plausible.

"Father loves you." Haru whispers, tugging on her sleeve to get her attention.

Sasuke definitely heard that though. Hinata could tell by how his eyes suddenly focused on the pair of the two. She felt herself blushing. Sasuke was looking at her from head to toe. He wasn't trying to hide it. Clearly he was…assessing her.

"Hinata." Sasuke says.

Hinata? He didn't see that coming. Sasuke didn't think he'd ever spoken to her in all honesty. If he had, it had certainly been a brief conversation. He knew almost nothing about her.

"Yes?" She asks nervously.

She was kind. Everyone said she was kind. Sasuke was aware she was also painfully shy or she used to be anyway. Hinata had been in love with Naruto. He knew that much.

"We need to talk." The last formerly last Uchiha says.

He never paid attention to who was lusting after who much, but Hinata's dedication to Naruto stood out. She had died for him after all. So how had he ended up the father of her child? It didn't make any sense.

"I know." She replies softly.

Sasuke remembered Hinata as an awkwardly cute girl at the Academy. Short dark blue hair with lavender bubble eyes that always looked so…startled. Now though, well that girl had been replaced by a woman.

She probably came up to his chin, which made her about average height. Her hair was like a beautiful waterfall of blue silk cascading over her shoulders and to the small of her back. She had fair soft looking skin.

Her eyes were one of her best features. They were still that alluring combination of lavender and silver. He'd always thought that the Byakugan had made people look so…cold. But not Hinata. Her every thought was on vivid display in those enchanting orbs.

"There's a storage room at the bottom of the hospital." He suggests.

His eyes drifted lower. That was a mistake. That was a really big mistake. She wore her headband like a necklace. Normally, that wouldn't have drawn his attention, but it just made Sasuke focus more on the tiny portion of a fishnet undershirt that was over her now ample breasts more. Thankfully, Hinata's voice shook him out of that daze.

"I'll meet you there?" She asks.

He nods. Hinata darted off. Her fashion choices had changed a bit. She wore a long white sleeved jacket and the rest of it was lavender in color. Said jacket subtlety caressed her alluring curves. Her pants were dark blue and ended a little below the knee, so he could see some of her shapely legs. They were fairly form fitting. This meant he could see the outline of her wide hips and the pants definitely flattered her rather nice looking backside.

"Naruto's an idiot." He mutters, following her.

He hadn't really noticed her before. She was just so quiet. It was easy to overlook her. But he had to admit that she was beautiful.

That was good news for Haru. Sasuke didn't think that physical attraction was going to be an issue in his conception. That was if Haru's mere presence didn't mess with he timeline.

Now that he thought about it, this raised some troubling moral questions. Now that he knew that Haru's existence depended on him at least at some point BEING with Hinata, was it murder not to have sex with her? He frowns. He didn't particularly care for the idea of "murdering" a kid, especially not his own "son."

Hinata could feel her face heating up. Sasuke was not being subtle in his appraisal. She could feel his eyes on her, as she headed to the storage room. Whereas Naruto had been…oblivious. Sasuke was apparently obvious.

"S-o here we are." She says and reverts back to fiddling with her hands.

"Yeah." Sasuke agrees, not sure what to say after that.

Well if Sasuke could look at her. She could look at him. Hinata had never really looked at him for any extended period of time. It was hard to imagine this man, she barely knew as the father of her child. She had to admit though, that he was very handsome.

"I thought you had a thing for blondes." Sasuke mutters, clearly deciding to break the silence with what might have been his version of a joke.

His hair was now black as night and he'd grown it down. His bangs didn't cover his forehead, but instead framed the sides of his face elegantly in spiky strands. The back of his hair, somehow still defied gravity. She didn't know this for sure, but she was positive it was just naturally like that. It was unfathomable to picture Sasuke spending hours styling his hair.

"It wasn't Naruto's hair color that attracted me to him." Hinata states far more boldly than she felt.

His skin was even lighter than her own, ivory. At the moment, his eyes matched obsidian stones in color perfectly. But she knew that at any moment they could turn ruby red or even at least one of them could transform into the trademark light purple of the Rinnegan. He had very much classical facial features, stunning in their refinement.

"Good to know." He says.

He wore a long sleeved white shirt and blue pants. Sasuke had broad shoulders. But the rest of him was sleek muscle. Whereas Naruto was built like a lion, all raw power. Sasuke was built more like a leopard. Sleek, graceful, and subtle power. Put simply, he was gorgeous. But she barely knew him. How could he possibly be the future father of her child?

"Sasuke…I…" She says, not sure what she thought she was going to say next.

Sasuke sighs. He walks over to Hinata. Well…at least she was sane. She was quiet. She was beautiful. So…all in all it could have been a lot worse. But he really had no idea how to approach her. He decided to throw himself on the "mercy of the court."

"Hinata, I know you don't know me well. But before the war, I did a lot of things…horrible things. I received a pardon, but there is no way they are going to trust me with him. Not without your say so. I know it is asking a lot. But please don't keep him from me." Sasuke pleads with her softly.

Hinata blinks. She'd never heard him speak in that tone of voice. It was so…soft. So gentle. So…unsure of himself. If there was one thing she associated with Sasuke Uchiha it was confidence. It was a strange sensation to see the transformation.

"You want him to stay with you?" Hinata asks in shock.

"Of course I do. He's my…our son. He's the only family that I have Hinata. And…I really don't know how your family will react to him. When they find out I'm the father…" He trails off.

Hinata winces. Sasuke had a point there. Her father was NOT going to be pleased. If Hinata had a child by Sasuke and in the future Sasuke recognized the child, that meant that she would have to marry outside the clan. He'd see that as a betrayal.

"I take it you see what I mean." Sasuke murmurs.

"Yes. Y-ou might be right. It might be better if he stayed in the Uchiha District. He say-s he'll go back home. He just needs someone to watch him for awhile." She says.

"So you won't keep him from me? You aren't going to challenge me to a custody battle?" Sasuke asks.

"N-o. You ha-ve just as much right as I do to see him." She mumbles.

"Thank you." Sasuke says and shocks her by pulling her into his arms, in a grateful hug.

"You're welcome." Hinata mutters in shock.

She blushes. Hinata realized she was in his arms. She was in the arms of the father of her future child. Idly, she notes that Sasuke smelled nice. He smelled like a pine forest and spring ring. She had expected him to smell like fire and smoke honestly.

His hold on her was firm, but gentle. She hadn't expected tenderness from him. He was really happy about her not fighting him over Haru, it seemed. He cared about him.

"I'll take good care of him." He promises.

"I know you wi-ll." She says with a blush.

"You can come to the District anytime you want. Like you said, I have just as much right to see him as you do. That goes both ways. He'll probably want to see you." Sasuke says.

"Okay." She mumbles and blushes at the fact she was still in his arms.

"He has your eyes and hair color." Sasuke says suddenly.

"And your everything else." She says.

"Well…he fidgets like you do. But he's brave. He didn't flinch when the bandits attacked him and tried to take his eyes." Sasuke says approvingly.

"BANDITS?!" Hinata asks.
