A/N: So I wrote this cause I figured, why the hell not. I was bored and I find this pairing interesting. The time is post war. So a lot of the characters might seem a bit OOC, and my spelling and grammar might be a bit off so please forgive me. Most of the writing I did was in the middle of the night and I was on a chocolate induced sugar high most of the time. (I LOVE CHOCOLATE INSOMNIA!) So please read and review. P.S: hit me up with some suggestions if you want some more SasuKaru fics.

Chapter 1:

Sasuke watched the redheaded girl from a tree at the edge of the training field. Onyx eyes following her every movement with obsessive focus. Her chocolate colored skin gleaming with sweat, panting breaths and shouts of her exertions echoing through the air.

If anyone had seen him, they would have assumed that the Uchiha heir liked the dark skinned kunoichi and was simply admiring her from a far. Though the truth was, he was simply assessing her. Pin pointing her weaknesses and flaws. As to why he was doing this he had no idea. Her katana flashed brightly as she swung at a training post, jumping back only to charge at it again. The cuts she made in the training post were small and shallow. But Sasuke knew that if a applied to a human target it would be much more effective. The marks she made on the bark of the stump were really not as random they seemed, each one aiming to sever an artery in the human body for a quick and easy defeat.

Yes Uchiha Sasuke has returned. After the war he decided to return to Konoha, but after his treacherous acts against the village hidden in the leaves and every other village during his time as a missing-nin. Many of the villages were threatening to break the peace treaty if the sharingan user wasn't fully persecuted for his crimes. Tsunade had managed to get most of the villages to forgive him through deals and bargains, assuring all of them that the young heir would be kept under control. Unfortunately Kumogakure was proving to be a little more difficult to convince. So he had to wait until the peace talks were concluded before he would be allowed to go on missions or enter the chunin exams.

Sasuke really went there to train and when he found the girl who was already occupying the area, he fully intended on leaving to find somewhere els to train. As he was about to though, he noticed a slight flaw in the girls attack. And another and then another. 62 minutes later he was perched on a branch high up in a tree nearby, listing all of her mistakes. 'Pathetic.' He thought as the girl moved around the training area. Though a seemingly impressive swords woman, her aim was off, her speed slow and her blows lacking. Sasuke simply didn't see why she was even trying. Clearly this girl was an amateur, probably hadn't even reached chuunin rank despite her age.

Just as he was about to leave (again), the girl stopped shoulders tensed, fists clenched tightly around the sword, glaring at the training post before launching herself at it again. Sasuke caught the look in her eyes in the moment that she had stopped. Anger. Pure seething anger dripping with lusty rage, almost like she was imagening her worst enemy in the place of the stump. 'So that's it.' He thought letting a smirk spread across his face. 'She isn't thinking clearly no wonder she's doing so poorly', he decided to toy with the girl for a while seeing as how there was nothing better to do.

He jumped down from the branch landing noiselessly on the ground and started walking towards her. She must have been so consumed by her anger that she was way too pissed off to notice Sasuke's presence or maybe she was just ignoring him.

He stopped to lean against a tree about twenty feet away, "Your form is sloppy." He said announcing his presence to the distracted girl. She turned to the side to see who it was and she froze. Sasuke saw the look of shock and disbelief on her face and started to wonder why. 'Please tell me she's not another fan-girl.' He silently hoped. Although most of the villages inhabitants could barely stand the Uchiha now, most of the fan-girls would still latch onto him every chance they got. Apparently his days as a missing-nin only intensified the brooding bad boy image they were all obsessed with.

His question was answered as the girls face changed from shock to anger. "What do you want?" The girl said, her words laced with venom. Sasuke stood there silent for a moment to take in the scene in front of him. The kunoichi was obviously tired. Sweat streaming down her face, her hitai-ate bandanna had fallen off about an hour ago leaving her fiery red hair to drape wildly over her shoulders and the bangs to stick to her sweat slicked forehead. Her white Kumo vest was also discarded at the same time as the bandanna. Her golden eyes burned with crouching rage watching his every movement and her fists were clenched tightly at her sides, body tense as if she was trying to hold herself back. 'This might be more fun than I'd hoped for.'

"Your form, its sloppy." He let a smirk slide onto his face as he continued, "if you'd focus a little more, maybe you'd be doing better." He said in a condescending tone.

"I said what do you want!" She snapped, rage flaring up. "I just thought I should make sure you were aware of the fact that your skills are severely lacking. After all with your incompetence, you might get yourself and the rest of your team killed." Sasuke saw the arm holding her katana twitch slightly. He almost smiled at her reaction, 'One more push'

"I didn't ask for your opinion, go away." She snarled at him before turning around walking towards her discarded clothing, restrained fury still evident.

"O.K, the rest of your team is probably just as weak as you are anyway. I'm sure they don't need any help getting themselves killed-" That did it.

Sasuke had barely finished his sentence before the girl had spun around and launched herself at him. He easily blocked her first attack. He caught her wrist spinning her around to send her flying into the middle of the training field. She stopped herself just before hitting the ground. Though Sasuke was enjoying himself he couldn't help but wonder why she was reacting so strongly. After all there are worse things he could have said to her.

"You need to calm down, anger will only cloud your mind." He said smugly

"Shut up Uchiha!" She screamed before restarting her attack. Sasuke smirked as he easily dodged her blows, before grabbing her by her waist spinning her around, he pinned her arms pulling her back against his chest.

"Hn, you'll never win that way. I see you know my name. Are you going to tell me yours or should I just call you Loser instead?" He asked with his head against her neck.

The girl struggled for a moment before answering,"My name is Karui." She took a deep breath and threw her head back to head butt the Uchiha causing him to stumble back in pain and release her.

Sasuke felt something trickle over his lips. He swiped a hand over his mouth and noticed blood smeared over it. He looked up at Karui to find her smirking at him katana ready to attack. He mentally face palmed himself for falling for such a weak attack, if you could even call that an attack. He narrowed his eyes at her anger beginning to boil up inside him.

"How's that?" She asked mockingly. The Uchiha glared at her his sharingan was ready to activate. He watched her panting heavily, obviously exhausted.

'She's not worth it, her chakra is almost finished. She won't last long.' He thought about just leaving, but something inside him made him stay.

"Hn. Lucky shot." He said as he pulled his sword from its sheath and stood ready to attack, "you won't get another one."

Karui lunged at him and katana's clashed. The clink of metal against metal echoed around the training field Sasuke was surprised by her sudden increase in speed and actually had to put in an effort to defend himself. But alas she started slowing down again. Chakra depletion and fatigue finally getting the better of her. Though Sasuke had to admit he was slightly impressed that she lasted this long, she obviously had amazing stamina. Deciding that he's had enough fun toying with the ill-tempered girl he picked up speed, backing her up against the training post she was attacking earlier. He gave her katana one last powerful blow, knocking it out of her hand. He pinned both her hands above her head with one hand while the other held his sword against her throat.

She glared up at him golden eyes angry and frustrated.

"Hn. I told you you'd fail." He said looking down at her smugly.

"BASTARD!" Karui snarled at him arms struggling to escape his grasp. Sasuke couldn't help but smirk.

She was weapon less, pinned to a tree with a sword at her throat, her chakra was depleted and physically exhausted. He could just kill her and discard her body without anyone ever knowing. And yet she still had the nerve to insult him. Sasuke felt something stir in the pit of his stomach, he couldn't quite place it. His eyes began to wander over Karui's face. For a girl with such a bad temper she was kind off att-...

Sasuke mentally slapped himself, the smirk on his face instantly fading. 'What am I thinking?!' He gave her one more undefinable look, one even he couldn't name, before releasing her and disappearing into the tree's. By the time Karui had managed to retrieve her katana he was gone.
