(A Boruto Fanfic) The Unknown Daughter: Chapter 1
Summary: While searching for Shin Uchiha, Naruto paid a visit to Orochimaru to find answers. He got more than he expected when he found a child named Hanami Uzumaki there alongside of him. Long red hair set into a bun, violet eyes that mixed red and blue, and a single whisker mark on each cheek. Had it really been around thirteen years since that night? Why hadn’t Karin told him anything?
“Lead me to Orochimaru.” A single demand made by Sasuke as they confronted two members of his old team. They needed answers about the person who’d taken Sakura, implanted with Sharingan.
Naruto entered Sage Mode immediately to avoid others having the drop on them again. His senses expanding as he caught the presence of two other people within the base. One was further out, but the other was nearing. “It doesn’t look like that’s gonna be necessary.”
Their eyes were drawn down the corridor, whereupon Naruto laid eyes on Orochimaru with a face that looked much younger than it had any right to. That, in itself, was a surprise for Naruto given that fifteen years had passed since the Fourth Shinobi War and the pardon had been issued—albeit with a guard stationed to watch him at all time.
However, a bigger surprise awaited them as he brought them into another room. The room itself was a laboratory. Monitors lining the wall, a solid steel table to the right, and three cultivation tanks with developing bodies within the center. Nothing out of the ordinary for the man who eluded death so easily.
But, in front of the tank with the most developed body, stood a young woman with her back to them. Long red hair set into a bun and decorated with a hair accessory. Dressed in a long sleeveless shirt that was plum in color and dark pants, she held her arms folded behind her back.
“It seems you were right, child,” Orochimaru said casually as the entered the room. “We have visitors.”
“One of their chakra feels warm. Radiant, as though I’m standing beneath the sun itself.” A slight turn of the head revealed her eye was a rich shade of violet, a blend of red and blue that had a single thin line beneath it. A shock ran through Naruto the moment their eyes met. “Are they guests?”
“I doubt they’ll here for long,” Orochimaru said simply as he came to a stop next to her in front of the tank.
“That’s too bad.” A bead of sweat rolled down from Naruto’s brow as the girl turned around to face them, the hair framing her face swaying to reveal the marking under her other eye to be a mirror image as she regarded them with curiosity. “We rarely have visitors.”
She’s a little taller than Sarada, maybe a little older. Naruto swallowed, but his throat remained dry. It can’t be…
Her curiosity drove her to approach the group. Tension threaded Naruto’s body as she passed him by. But either she didn’t notice, or she didn’t care as she came to a stop in front of Sasuke, her head tilted as she regarded him with a hand on her cheek.
“…You’re Mother’s old teammate, aren’t you?” she asked him. “Sasuke Uchiha… I’ve seen you in the picture, and Mother talked a lot about you.”
Sasuke regarded the child with a glance before shifting his gaze to Orochimaru. “Karin had a daughter?”
“Indeed,” Orochimaru said, holding his hand out towards her. “Introduce yourself, child.”
She did so. “My name’s Hanami Uzumaki. It’s a pleasure to meet you all.”
“Isn’t that Lord Seventh’s family name?” An uncomfortable number of eyes fell onto him at Chocho’s obvious question. Including that of the girl herself.
Naruto even heard Suigetsu mumble, “You know, Karin was always cagey on who the father was.”
But Orochimaru brushed it off with a dismissive, “One of my subordinates comes from the same clan as Naruto-kun.”
“Is that so?” Hanami mused as she took a step closer to him. “It doesn’t look like the dominant genes are present within his facial features or hair pigment. But I suppose some genetic variations should be expected given the different variables.”
Sasuke… couldn’t care less. Or rather, any curiosity he possibly had was buried beneath the mission. “We didn’t come here for that. We came here to find out about that man and child who had Sharingan they shouldn’t.”
“He’s an old experiment of mine named Shin,” Orochimaru explained. “You recall the arm that Danzo Shimura possessed, correct? That originally belonged to him. Since that child possessed a rare genetic trait that prevented rejection of tissue transplants, he was the ideal subject for experimentation with cloning.”
Naruto looked away from the girl at the familiar word. “Cloning?”
“Think of it as a Shadow Clone that won’t disappear,” he clarified. “A perfect replica of an individual down to their very genetics. Only it persists indefinitely.”
“If it’s like a clone that won’t disappear, then what do you do with them when you’re done?” Naruto asked.
“Your only option is to kill them, obvious.”
He naturally took offense to that. Life was sacred after all. To just dispose of them when they weren’t useful anymore disregarded the feelings and connections they formed. “Humans aren’t simple things to be discarded like that.”
“Humans are much simpler than you think.” Orochimaru turned to the cultivation tank with the largest body grown within. “Hanami has taken an interest in this particular field of study, so I suspect she can explain it.”
The girl nodded and then did so. “A person is basically determined by their genetic material. Skin color, abilities, everything can be traced to the genes that compose them. I look more like my mother and possess many of the same abilities as her because her genes were passed onto me, after all. So, for a clone who is made of the same genetic composition, there would be virtually no difference between them.”
“Exactly,” Orochimaru said. “The same applies to your daughter, Sasuke-kun. She looks like you because half of her genes were passed on from you. It’s all simply data recorded in an organic material, rather than an electronic one.”
…That’s not right, Naruto thought to himself while looking at the girl who bore his clan’s name. Those words weren’t something he ever wanted to hear coming from a child.
However, Sasuke took control of the conversation before he could voice it. “Why does that person call himself an Uchiha?”
“That’s his own doing,” Orochimaru said. “Though he is not an authentic Uchiha, he possesses the Sharingan and he ended up becoming obsessed with the Uchiha name. In particular with your late brother, Itachi Uchiha.”
“I see…” Sasuke closed his eyes for only a moment. Silently considering it. “Where can I find him?”
“Hmm… I suppose it would benefit me if your village were to capture him,” Orochimaru mused, before turning to Naruto. “Besides, I do owe you, Naruto-kun. How is that child doing, by the way?”
“…He’s doing well,” Naruto answered, albeit with more hesitation than he should have. “Though, if you’d told me that there was another child in your care, we would have accepted her as well.”
Orochimaru lightly chuckled. “That wasn’t my call to make. I only helped deliver Hanami, after all. Her mother was the one who decided to raise her as she has. All the questions related to that can be answered by her.”
Naruto breathed slowly through his nose as he caught the underlying message. “I understand.”
“Good.” Then he started to walk. “As for Shin, I’ll explain more in a room with a monitor. Follow me.”
Naruto did so, occasionally glancing subtly to Hanami as she walked behind them with Sarada. He knew he should ask the question, but he couldn’t find the words. Not right now, with Sakura’s life potentially at stake. But it gnawed at the back of his skull until he heard Sarada broached a question that drew the child’s interest.
“Your mother was the person in this picture, right?”
“Yes, when she was younger,” Hanami answered just as quietly. “I’ve seen that same picture in her office.”
“Is she here now?”
“No, she’s at a different place at the moment.”
“Oh… then, can I ask you something?”
Naruto watched out of the corner of his eye as the two girls went off. He knew that Sarada was doubting her connection to her mother from how she was behaving, but he had no doubts about it. Even if, by some chance, that Karin had given birth to Sasuke’s child and then passed her over to Sakura, the bonds between family through connections should be stronger.
But what about Hanami? Taking into account the nine months and Hanami’s appearance, there was very little doubt in his mind of her parentage, But, he didn’t want to think it was true, because Naruto didn’t want to believe that she lied to him thirteen years ago. Why didn’t she tell me?
He had to know that much at least. So he followed the girls to the office in secret and listened from next to the door, peeking through carefully.
“First we need a sample of your DNA,” Hanami explained, handing Sarada a buccal swab. “Simply rub the inside of your mouth with it and it’ll collect DNA samples. I’ll do the same with mine and then we’ll use this machine to analyze the data. If there’s enough of a match, then this will show that we’re related through the same mother.”
Once Sarada did as told and the analysis began, Hanami then added. “If I have to be honest, I hope that there is a connection.”
“Why?” Sarada asked.
“Because, if we are then we’ll be compatible enough for an eye transplant.”
Sarada tensed. “Huh?”
“If I gain the Sharingan while being a descendant of the Uzumaki Clan, then I’ll be able to test a theory on awakening the Rinnegan like your father has,” Hanami explained with a smile. “It’s exciting to think about, isn’t it?”
‘…Kurama, is that true?’ he asked. Until now the fox had been silent, observing without commenting. That in itself was worrisome.
‘Not likely. She’s not a direct transmigration of Father’s children as you and Sasuke Uchiha are,’ Kurama answered. ‘However, given who she has been studying under, the fact that chakra does transmit through genetics to some extent, and the fact that he hasn’t dismissed the theory itself, there’s a very faint possibility. More so if he managed to procure some of Father’s chakra during the War fourteen years ago.’
The implications of what he just heard made his stomach drop. Not because of the fact that those eyes even possibly returning in the hands of a child being raised under Orochimaru possibly spelled very bad things. But because he didn’t want to think that night, thirteen years ago, had been contrived for the sole purpose of making that outcome possible.
Sarada was naturally wary at the prospect, albeit for different reasons. “You want to take my eyes!?”
“Oh, not for good!” Hanami quickly added. “I’d give you mine until I awoke them and then I’d transplant one back. That way we’ll both have one, and there’s the potential for that to pass on as well through two different family lines with a little genetic modification. Though, if the Seventh Hokage has a male child then you could have a child with him as well and they could possibly inherit it.”
“I’m not having a child with Boruto!”
“Well, if you have a brother then I suppose that I could—”
“Are you seriously offering to have a child just because of the potential of their genetics!?”
“I mean, isn’t that better than letting them die out if something happened to us?” Hanami asked. Worse, from her tone she was being sincere. “Our clans are endangered after all, but as long as our genes pass on through our reproductive cells then they can live on. That’s how life works in the end.”
“But having a child means starting a family,” Sarada argued. “It’s not just a matter of genes. There’s something more there. Something precious.”
“Families just people linked by genetic material,” Hanami counterargued. Chakra chains began emerging from arms as she held them out in proof. “It’s an assembly of DNA where strong one’s merge to become even stronger and weak ones die out. You’re a prime example of that, just like I am.”
Naruto… couldn’t listen to this any longer. It was like listening to Kabuto for a second time. He emerged from behind his cover and said otherwise, “That’s not what a family is.”
“Lord Seventh?” Sarada was taken aback. Likely because of her reasoning for coming here in the first place, despite the fact that her mother had been taken. “I…”
Before she could say anything to justify the feelings that had driven her, the computer beeped. The results were in.
“It looks like they aren’t a match after all.” Hanami sounded disappointed as her chains disappeared. Then she perked up. “Then again, if this Shin person has a Sharingan and their tissue won’t reject me, then it should be possible to transplant it that way.”
“H-Hey—” Naruto tried to stop her and explain his point, but she ran past him in the direction they’d came. Towards Orochimaru and the others. “Sarada, go with her. This is a sensitive matter, and I don’t think Sasuke would like the notion of someone transplanting those eyes at all.”
She ran off after her, leaving Naruto alone. He watched her leave before turning back to the machine. He had to know for sure.
So, he went through the motions with the buccal swab, taking out the one that Sarada had used and replaced it with his own. Then he set the analysis to begin. The results…
They were exactly as he expected.
He looked to the photo on the desk and a weight that pressed down on his shoulders. The memory of that night felt like a vice clamping around his heart when he considered everything he’d heard. He needed time to process it all.
But Sakura came first. Reuniting mother and daughter came first. Then, when that was done, he would have words with Karin.
About how she had lied. About how she hid his daughter. About how she let Orochimaru’s thoughts on genetics dictate what her definition of a family was.
He told his own son that to the Hokage, everyone in the village is family. Because a family was the bond between people, not just history or blood. It was the love between them that dictated who your family was.
Even if she hadn’t been his daughter, the fact that a child wasn’t able to understand that…
It meant that something was very wrong.
Author’s Note: The premise of this… random thing is that sometime before Naruto paired off with Hinata after the whole moon thing (2 years after the war if I remember right), he had a one-time tryst with Karin Uzumaki. However, she never told him that she was pregnant or that she gave birth afterwards. Then, over a decade later, the Sarada Uchiha story arc happens and Naruto runs into Karin’s child.
