Naruto (c) Masashi Kishimoto
"Uh... don't go," she called out to the dark eyed boy. She stood up slowly, eyeing the bear warily, unsure if it would awake and try to eat her again. The boy stopped and turn to look at her.
"I have to get back to my team," he said.
"I'm separated from mine," Karin bit her lip. "Can you help me find them?"
"No. I told my team I'd be back shortly with water," the boy replied. Karin frowned briefly as she puzzled out her next question.
"If... If we work together... I help you find water and you help me find me team... would that be fair?" she asked.
The dark eyed boy frowned for a moment before giving her the briefest of nods. "Very well." He jumped down besides her. "Uchiha Sasuke," he informed her. Karin blinked as she adjusted her glasses, realizing that they hadn't properly introduced themselves.
"K-Karin..." the red haired girl said, remembering her father's words not to reveal her clan name to anyone, just in case someone came looking for the last members of the Uzumaki clan. Sasuke nodded and didn't press her for more. "So, uh... I think I heard some water this way," she turned and trotted off in the opposite direction of the bear, Sasuke close on her heels.
"What village are you from, I can see your headband clearly."
"Kusa," Karin replied in an offhanded sort of way. She scanned the area for her teammates, but the only chakra she could feel was Sasuke's. It felt... different. Very different, like a snake that just slithered into the shade after sunbathing. She suppressed a shudder. "Look, I think that's water up ahead," she pointed to where she could hear the babble of a brook.
"Good ear," he nodded to her, jumping ahead of her in a few quick leaps. She followed him, and looked around again, hoping to find a glimmer of her teammates' chakra. Nothing. She watched Sasuke fill up the canteens with water. "Thanks for the help," he said, eyes glancing around. "Have you spotted your team?"
"N-No... I think... we got separated. That bear attacked us and went after me... I fell down," Karin looked at her feet. "Anyways, I'm sure I'll find them. I can sense chakra."
"Oh, you're a sensory ninja," Sasuke blinked. "Do you want me to stay with you until you find them?" he could hear Sakura scold Naruto for not making such an offer to a lady in distress.
Karin blushed, her cheeks matching her hair and eyes. "Oh, no that's okay. I'll manage. Oh, I think one of them is coming now. I'll just stay put," Karin said.
"If you're sure," Sasuke shrugged. "See ya," he smiled and leapt into the treetops vanishing in a few heartbeats.
It turned out that her team had been disqualified and that Masahiro was in the hospital. Karin was a bit glad that she didn't have to go through the final test, not after seeing that poor Hyuga girl come in. Karin had spent the entire night monitoring the Hyuga girl's chakra, just to make sure she'd live to see the morning.
Karin had become rather familiar with the hospital, between visiting Masahiro and checking up on the Hyuga girl, she soon knew the place like the back of her hand. Seiji didn't approve of her always going back to the hospital, but until Masahiro got better they couldn't exactly head back to Kusa. Plus Karin liked Konoha, it was much bigger than her tiny village.
She dashed behind a corner when a white haired man followed by a loud obnoxious blond walked by. She recognized the swirl pattern on the blond's jumpsuit, frowning in puzzlement because only full fledged members of the Uzumaki clan could wear the symbol, or so her father told her. Then again, she's seen it on every chuunin and jounin in Konoha. They couldn't all be Uzumaki shinobi. She shook her head, made sure the duo were well gone before going around the corner.
She was surprised to find him in the hospital. He seemed so strong and invincible when he defeated the bear. Now he looked rather pathetic, in the hospital bed. "Hey," she whispered, drawing his attention from the window.
"Hello," he replied politely. "Did you find your team?"
"Oh," she blushed, "yes but erm... we were disqualified. Masahiro-kun is in the hospital. We're waiting for him to be released before we head back to Kusa."
"Oh, well... maybe next year."
"Did... did you win your match?" she asked.
"Naturally. I'm an elite Uchiha."
"That's good. Are you still injured then?"
"I'm recovering from my injuries I sustained in the Forest of Death," Sasuke replied.
"Oh..." Karin looked around making sure nobody would sneak up on her. "I do have one other ability."
"You know it's stupid to tell an enemy shinobi your secrets."
"Kusa and Konoha aren't enemies," she snapped. "I'm just trying to help you, meathead!"
"Hey... chill..." Sasuke blinked, unsure on why the girl suddenly snapped again. "I'm just giving you advice."
"Well..." she huffed before hopping on to the bed. She unzipped her shirt a bit and exposed her shoulder, yet unmarked. "If you bite me, you'll be able to suck my chakra and heal."
"That's... gross..." Sasuke frowned.
"Do you want to stay in here longer or not?" Karin snapped.
"Fine," he looked at her, "does it hurt?"
"It... feels weird but it doesn't really hurt."
"Hn," he shrugged, grabbed her shoulder and bit down. Karin gasped, shuddering as he sucked out her chakra. She had only don't this a few times with Seiji and Masahiro. Never a complete stranger, and never one so mysterious as Uchiha Sasuke. He let go after a few moments, gasping for breath. "I feel... so full of life," he murmured.
That's the Uzumaki chakra for you. It has extreme vitality, hence why you can suck it out of me and heal yourself. Karin didn't say that of course, she just nodded, traced the new bite mark before pulling her shirt back into it's proper place.
"Will it go away?" Sasuke asked, suddenly as he pointed to her shoulder.
"No. Once someone bites me to use my heal bite jutsu, the bite mark stays. I remember everyone that has bit me to use my heal bite jutsu," Karin said.
"Oh," Sasuke nodded. Karin looked over to the door, spotting a tuff of pink hair.
"I have to go," Karin said, adjusting her glasses on her nose. Karin hopped off his bed and ran to the door. "See ya!" she waved over her shoulder before pushing the door open and neatly avoided colliding with the pink haired girl. Sasuke stared back after the girl.
It had been three fateful years since their first encounter during the Chuunin Exams. And those three years had changed them. Karin was no more the shy girl she once was. The lost of her entire village made sure of that and Sasuke... well he had shed his skin and became a serpent with it's glittering black coils wrapped around his heart.
Yet he still somehow managed to save her from another raging bear. "Idiot," he hissed.
"Wh-What?! I had everything perfectly under control, Sasuke! You didn't need to butt in!" Karin snapped, pushing up her glassed.
"Hn," was his only answer as he turned to face her. Sleek and muscular like a jungle cat stalking it's prey, he walked towards her. Karin felt her back hit the tree. "What were you going to do?"
"I was going to throw some perfume into it's face and then..." she gulped when he placed a hand on her shoulder, the very same shoulder he bit what seemed like a life time ago. "Run," she breathed.
"Hn." The Uchiha smirked before leaning forward and kissing the bite mark.
I was looking through SasuKarin stuff on DA and I felt inspired. I do so love them as children. ^^
I imagine that Karin knows she's an Uzumaki. Her father or mother (in the story it's her father) is a member from the Uzumaki clan and fled the destruction of the Uzumaki village of Whirlpool, settling in Grass Country and becoming a member of Kusagakure. He probably told Karin all sorts of stories about the powerful Uzumaki clan and also to never tell anyone her true identity in fear of whomever came and destroyed Whirlpool would come and kill them. Hence Karin only gave Sasuke her first name, and since Karin didn't know that Uzumaki Mito was the wife of Senju Hashirama or that Konoha and Whirlpool were once close allies, she's a bit confused why Konoha has the Uzumaki crest on their chuunin jackets.
