Author's Note: Alright guys, this is to make up for the Elastic Heart fanfic as it should of been a one shot instead of a full fanfic so to make up for that fanfic, here's a different NaruKarin fanfic and it's a collaboration of two fanfics I know. (Sort of). No promises, I may or may not complete it but we'll see how it goes.

Disclaimer: You know DAMN well I don't own Naruto.

Summary: The mission to bring back Sasuke went down south. Sakura, Sai, Yamato were killed and Naruto was kept as prisoner by Orochimaru, and his jailer was a beautiful red haired girl named Karin. Lately Kabuto has been experimenting on Karin and she doesn't know why, but then she found out. Karin is pregnant with her prisoner's baby. Orochimaru was trying to create a strong baby to become his future vessel. Naruto found out and was pissed. Then he realized this is the only family he has and he'll do anything to protect them.

[Post Tenchi Bridge Arc]

Chapter 1

XXXX

"Gahh." Naruto lets out a slight and painful groan as he opens his eyes slowly, greeted with an annoying sun beam and he was wearing a straitjacket. "Where am I?" He asked himself.

Then he suddenly remembered and shot up from his back. "SAKURA!? SAI!? CAPTAIN YAMATO!?" He shouted, hoping what he witnessed was all a bad dream. "SAKURA! SAI! CAPTAIN YAMATO!" He cried. "Please answer me." His eyes watered at the memory of Sakura, Sai and Yamato falling.

That day, Naruto regretted it. There's no point in keeping that worthless promise to Sakura. Sasuke is dead to him now.

Flashback

Naruto, Sai and Yamato are wounded after their battle with Sasuke and Sakura in the background crying her eyes out.

Naruto, who just got out his conscience with the nine tails, he spoke. "Why won't you let us save you? Why won't you come back to the village?" He asked.

Sasuke just looked at Naruto with cold eyes. "I have no reason to come back when none of you will help me get stronger. Forget it. You and the village mean nothing to me."

Sakura's eyes watered. "Sasuke, please come back. I missed you Sasuke."

"Is there even a single day you never thought about me?" He asked, starting to get annoyed. "Forget it. If you won't give up on me. Then I'll just kill you all. Itachi was going to be the first one to get hit by this jutsu. Fuck it." Sasuke raised his arm, going to end his ex-teammates.

Until Orochimaru grabs his arm. "No need to waste that jutsu on some desperate insects. However, now they know our base, there's no point in keeping them alive though."

Kabuto looked at Sasuke. "How about it Sasuke? Should you finish where you left off?" Asked Kabuto.

Sasuke nodded. "Works for me." Said Sasuke.

Team 7's heart stopped in fear. They're going to die.

"Sasuke don't-." Sakura widened her eyes at the sudden sharp pain she felt through her chest. Sasuke chidori Sakura through her chest, where the heart was. "Sa… suke… why?" She asked. Tears left her eyes as blood came out of her mouth.

Sasuke just stared at her, feeling no remorse. "As I said three years ago that night. You. Are. Annoying. Goodbye Sakura." Sasuke yanks his arm out of Sakura's chest and let her fall to her death.

At Sakura's last moment, she felt betrayal. The boy she loved stabbed her without hesitation. She looked at Sasuke with an almost blurry vision, his back turned to her. She now realizes she had Sasuke all wrong. She had a crush on the wrong guy.

Her eyes slowly closed and took her last breath. Sakura. Is. Dead.

The remaining Team 7's eyes widened in horror. Sasuke killed Sakura in front of them. "SAKURA!!!" Naruto cried. "YOU BASTARD!! YOU KILLED HER!! I'LL. I'LL. I'LL FUCKING KILL YOU!!" Naruto shouted, nine tails' chakra covering him again.

Before Naruto could make a move, he was bound by Orochimaru's snakes. "Ah ah ah, don't even think about it." One of the snakes lifted up Naruto's shirt, revealing his seal. "FIVE PRONGED SEALS!" Orochimaru shouted, the same sealing jutsu he used on him during the chunin exam.

Naruto shouted in agony. The chakra retreats and his red slit eyes are back to blue. Naruto falls unconscious, realizing Sasuke is long gone and Sakura is dead. And so will he.

Sasuke then walks over to Naruto, planning to finish where he left off. Until he was stopped by Orochimaru. "What now?" He asked.

"Actually, I need him alive for a while. I have something in mind." Orochimaru said with a sadistic grin.

Present Day

That was all he could remember before he blacked out. Sakura died in front of his eyes and Kami knows what happened to Sai and Yamato. He cried, his best friend, who he had a crush on is dead.

"DAMMIT!" He shouted. "DAMMIT! DAMMIT! DAMMIT!"

Suddenly he heard a door open. "Can you shut the hell up with your shouting!" An unfamiliar woman shouted, on the other end of the room where the sunlight can't reach.

"Where the hell am I?" He asked, not caring if he was loud. "And who are you?"

"You're in one of Orochimaru's dungeons and my name is none of your concern." She snarled.

Naruto's eyes widened. He's in a dungeon. Which means he's a prisoner to Orochimaru. "Dammit!" He shouted again. "Damn him. Damn that snake. Damn Sasuke." Naruto slams his head to the wall over and over.

"Hey hey HEY!" The woman shouted, starting to get scared of his chakra. It was small, but she felt anger, sadness and regret from it.

To her relief he stopped and let the tears flow, not caring if his head was bleeding. "I need to get out of here. Like hell I'll be his prisoner." Naruto struggles to get the straitjacket off but fails. "FUCK!"

The woman sighed and got closer to his cell, sliding the tray of food under it. "Here." She said, getting in his cell. "You need to eat."

Naruto looked at the woman and was a little caught off guard by her appearance. She has red spiky hair, crimson eyes and glasses. She wears a purple shirt and small shorts. And she looks like she's in his age group.

"What are you doing?" He asked her.

"It's obvious you can't feed yourself and who's stupid enough to take that jacket off you." Said the red hair teen.

Of course, the moment this straitjacket gets off Naruto he'll make a run for it. Naruto sighed, he was already a prisoner so what can be worse than that.

"Fine." He said, allowing the girl to feed him. Though disappointed it ain't ramen. "How long have I been here?" He asked.

"Two Days." She asked, she could feel the same depressed chakra from him. She expected him to go on another panic attack and he didn't. Has he lost fate? "Mind if I ask why you're here?" She asked.

Naruto looked at her with a raised eyebrow. "I thought the pale pedophile and silver-haired Harry Potter wannabe would have told you." Naruto can see the look on her face and was sure he was going to get sock by insulting her master.

Instead, she laughed. "Hahahahaha. That's the funniest thing I've ever heard. Hahahahaha." This wasn't the reaction Naruto was expecting. In fact, seeing her laugh kinda made him smile. "No he hasn't told me." She said.

Naruto, seeing no point in hiding it. He told her everything and she felt bad for him. No doubt Orochimaru or Kabuto would do that but Sasuke only wanted to kill his brother and no one else. She had a small crush on Sasuke but she never thought he went that far to kill his teammate, especially the girl who loves him.

"I'm sorry." She said out of sympathy.

"No need. You weren't the one who's responsible for their death." Naruto looked at the window. "Still, I'll be damned if I stay here." Said Naruto.

The woman looked at Naruto with a sad expression. With his condition, it's impossible for him to escape. And if he escapes, Kami knows what will happen to her if Orochimaru finds out. And Kami knows what sick and twisted experiment Orochimaru got for him.

"Karin." She said, getting a confused look from Naruto. "You asked my name. It's Karin. Uzumaki Karin."

Naruto's eyes widened in shock. "My last name is Uzumaki."

Karin looked at him confused. "But you're blonde, how can you be in the Uzumaki clan?"

"Clan?"

Several Weeks Later

Naruto has been in the dungeon for a month and a half, yet still trying to exit. Although he rather enjoyed Karin's company, almost wanted to stay and not leave. But he has to remember she's Orochimaru's subordinate so they're technically enemies.

Speaking of Karin, she usually comes to his cell daily to give him food or just talk. It's been two weeks since he hasn't seen her and someone else has been sending him food. He felt lonely again.

Meanwhile in the Medic Lab - Karin POV

Karin was used to the experiment Kabuto had done to her. Since it wasn't harming her, she didn't bother to ask what he did to her, but this was different. She was sleeping through this experiment and woke up to Kabuto's voice.

"First test and it was a success. Well I wouldn't be surprised, you are an Uzumaki after all." Said Kabuto.

Karin usually doesn't ask what he has done but this experiment made her feel sick to her stomach and she was unconscious through it. "What did you do to me?" She asked.

Kabuto smiled. "Well considering this experiment is different from any other experiments you've taken I figured you might ask, and it's big news for you." Said Kabuto.

"What news?" She asked, not liking where this is going.

"Congratulations, you're pregnant. You're going to be a mom." Kabuto said with a fake smile.

Karin's eyes widened and twitched. "WHAT!?" She shouted. "But I haven't been with anyone!"

"I know. It was artificial insemination. That was the experiment." Said Kabuto. "That baby will become the future vessel of Lord Orochimaru."

Karin's eyes widened in horror. She knew Orochimaru was a psychopath but she never thought he would go this far. This will scar her forever, watching the life she gives is taken by a power hungry mad man.

"Who's the father?" She might as well ask.

Kabuto gave her a wicked smile.

The Next Day

Naruto spends his day trying to get out the straitjacket, all he managed to do was stretch it out. As soon as he heard the metal door he looked at who's entering the room and saw Karin. And it looked like she was crying.

"Karin-chan." A part of him was happy to see her but he felt worried. "What's wrong?"

She immediately gets into his cell and hugs Naruto, crying and his shoulder. If Naruto wasn't in that jacket, he would hug her back. "Naruto. There's something you need to know."

Naruto looked at Karin, giving her his full attention. "What is it?"

"I'm… pregnant, with your baby." She said between sobs.

Naruto's eyes widened in horror.
