Sasuke's breath was hot on her neck and his hands roughly grabbed at the top of her pants in an attempt to rip them off her. Naru could feel Kurama's chakra engulfing her, the red cloak it formed going unnoticed by Sasuke as he was too focused on getting her undressed. She groaned as her nails grew long and pointed into claws and her teeth followed suit. The red chakra coursed through her veins violently and she let out a deep primal growl, causing the Uchiha too look up. He backed away from her to inspect her new form as she bent down on the ground to get onto all fours as if she was an animal.

"Never…touch…me…again" she spat out, Sasuke merely looked amused the lust in his eyes darkening at her new primal form. She sprung at him, hand curled as she took a swipe at him. Sasuke narrowly missed her claws as the struck his shirt, tearing it in the center. He expected Naru to wait before striking again but she came at him relentlessly, blow after blow getting closer until she finally hit him. Naru smiled a Cheshire cat smile as he flew backwards, barely able to maintain his balance as he landed on his feet

"So this is the nine tail foxes chakra?" Naru dug her claws into the ground as she became overwhelmed with heat as if she had lava seeping out of her. The chakra coat began to form a tail behind her and she let out an ungodly howl when it finished.

"SASUKE!" she began to attack him again, blow after blow hitting to boy as he held his arms over her chest in an attempt to protect his vital organs. He dropped his arms as he tried to regain his breath, panting as he contemplated his next move. He had never expected he would have to go to second state of the curse mark to defeat Naru but he sensed that the chakra she was emitting was only the start of it.

"You think you're the only one with hidden powers Naru? No matter what you do I will always be one step ahead!" He pulled his shoulders back, his eye's filling with a black ink turning them completely black; his pupils staying the sharingan red. A star shape began to form from his nose, stretching over the middle of his face. His skin turned a clammy grey and she yelled out as meaty, mutated hand like wings sprouted from his back. Naru let out another low primal growl at the transformation, barley being able to recognise her form team member.

…

Kakashi and Pakkun looked down at the scene in despair, there was nothing they could do to stop the two without getting themselves killed. They were both too far gone. Kakashi sat down on the grass, his head resting against his hand that was propped up on his elbow.

"They're going to kill each other Kakashi" Pakkun stated in an attempt to get his master to do something. Kakashi sighed, his eye's never leaving the battle below as his two students flew at each other in an impossible rage. He knew there was rivalry and obviously a lot more behind the scenes from what he previously saw but he had never expected something like this to happen. Surely they wouldn't resort to killing each other?

"We just have to wait until one of them gets knocked out, there is no point in rushing in a getting ourselves killed" Kakashi shook his head in disbelief. Had he been that bad of a teacher he had let so much happen right under his nose? Tsunade would have his head.

…

Naru summoned a shadow clone, holding her hand out to once again use the rasengan. Sasuke looked bored with her as she used the same jitsu again and began to form his chidori. So this is how it was going to end he mused, one of them would either end up severely wounded or dead after this. Naru stared at the lightning that had now become black and ominously while Sasuke eyed her red chakra cloaked rasengan.

"I hope you're ready for what will happen if you lose little fox" he smirked at her and Naru narrowed her eyes. There was no way in hell she would let him touch her like that again, she had had enough of it.

"I'll kill you before you can lay another hand on me Uchiha" the purple haired boy laughed, a sinister and knowing smile on his lips as he went over all the possible positions in his head. He would enjoy breaking her. Naru jumped so she was above Sasuke, a determined look in her eye as he held out his hand in front of him, using his other hand to support the weighty jitsu. Naru's rasengan began to slice through the black lighting but stopped half way down, she tried to press forward and frustrated scream erupting from her lips as she willed herself forward. A light began to surround them from the power of the jitsu's colliding and it looked like the detonation of a bomb. The light grew until it hit the sides of the two cliffs before exploding, throwing each participant violently against the shattering cliff fronts. A sicking thud was heard and Naru groaned before the darkness took her.

….

Kakashi held his hands in front of his face to shield his revealed eye from becoming blind and he was knocked onto his back. Pakkun had is paws covering his ears and the two quickly stood up, ignoring the ringing in their ears. Kakashi jumped into the now cratered canyon, searching through the fog of the explosion. He managed to make out two shadowy figures, one leaning over the other which was lying face up in the dirt. He stayed where he was until the smoke cleared and glared as he saw Sasuke crouched over Naru's unconscious form, his fingers running over the girls lips as he licked his lips. Kakashi's stomach churned at the sight, the need to protect Naru filling him. He watched as Sasuke ran his hands over her exposed skin that was showing through he ripped top and quickly sprinted over, dropping his shoulder into the now normal formed boy.

"Get the fuck away from her Sasuke" he stood in front of Naru's body, crouched in a defensive position and a kunai in the front hand. Sasuke sighed and ran a hand through his now black hair, a disappointed look on his face.

"I do wish you didn't interfere with my prize Kakashi Sensei" Kakashi's grey eye narrowed in anger and he clasped his kunai tighter, his knuckles turning white.

"I'll kill you myself if you lay another finger on her" Sasuke stared at his former teacher for a moment before sighing. He was nearly out of chakra and there was no way he could take on Kakashi in the state that he was in.

"I will have her sensei" He turned his back on his former comrades and gave a bored two finger wave "Tell her I'll see her again and that next time she won't escape me" Kakashi watched as Sasuke quickly made his way away from them towards to forest on the other side. He made no move to follow him, his main concern was Naru and after what Sasuke had done he couldn't care less if the boy lived or died. He spun around as he heard Naru whimper in pain, her wounds slowly healing thanks to Kumara.

"Kakashi Sensei?" she fluttered her eyes open and Kakashi let out the breath he had unknowingly been holding and grabbed her hand. He quickly put his kunai away and brushed the wet hair out of her face.

"I'm here Naru…" a small sigh escaped her lips and her eyes fluttered back closed. Kakashi lightly picked her up and looked down at the battered body of his former sensei's daughter. His heart thudded in his chest and warm feeling began to spread throughout his body. He took in every feature, every strand of hair and counted every eyelash. Even badly torn she was still beautiful. Kakashi frowned at the thought, she was his student and he shouldn't be thinking such things about her.

"Where's Sasuke?" he wasn't sure if she was conscious or not but chose not to answer, holding her tighter against his chest at the mention of the now rouge ninja's name. He made up his mind then and there that he would protect her, even if that meant killing his former student.
