A/N: Next chapter, hope you like it. Oh and Haku is kinda violent. (Rating gone up.) Chapter updated!
Haku Absolutely Loathes Demons
"You're a monster! I'm gonna tear your limbs off one by one and stab you the number of my clan killed."
Naruto stared in awe. "Wow, you are passionate."
"SHUT UP!" Haku screamed and charged at an incredible speed. Kakashi tried to move but Zabuza's sword swipes at him, blocking the way. "Oh no, you're my opponent."
Haku pulled out her throwing needles and threw them at Naruto, which were swiped by Naruto's chakra covered hands. Haku realised that the needles couldn't penetrate. His companions, I'll go for them to distract him into helping them. He thought in a feverous manner.
He linked his fingers together. "Secret jutsu: Crystal ice mirrors!" Haku heads for Sasuke and surrounds him with mirrors. Sasuke tries fireball jutsu but unfortunately the ice didn't melt.
Suddenly needles came from everywhere and scratched Sasuke. He yelled in pain and was thrown back onto the ground.
"Sasuke!" yelled Sakura. "Sakura, stay there with Tazuna, I'll go help Sasuke!" Naruto yelled and charged off towards the mirrors holding Sasuke.
He stopped outside the cage just as another barrage of needles hit Sasuke. If I go in I'll be trapped in there too, and that's just what he wants. But suddenly the mirrors started moving and surrounded him. He tried to hop out of it but before he could needles not only skimmed his skin but actually dug into his body.
And Sasuke was still in it too.
Naruto surrounded himself with his cloak and ran towards Sasuke but when he tried to grab him he backed away from the intimidating cloak.
Naruto got frustrated. "Sasuke, you idiot, forget about me being a scary demon and trust me!"
The needles were coming at them so Naruto jumped in front of Sasuke to block the attack. This went on for a while, neither gaining the advantage.
Unfortunately, Naruto's human body wasn't able to create chakra as quickly as a fox form and the cloak weakened, allowing a few needles to jab into him.
Slowly the cloak diminished and Naruto was on all fours puffing from chakra exhaustion. He had used up most of his chakra and he had to wait for his body to make more, which wouldn't take more than a few minutes, but time wasn't on their side.
Haku seemed to be in all the mirrors at the same time. He looked at Naruto. "So, there is a limit to you power. Well, I'll just have to make the most of it." The needles flew, completely ignoring Sasuke who lay shocked, and sunk their tips into Naruto. He winced.
He could feel he was about to blackout, the darkness threatened to overtake his senses. He pried his eyes open and saw that Sasuke had jumped in front of him and Haku was calmly walking towards them.
"Boy," Haku said. "You should leave now, I don't want to kill you, just the thing behind you."
"No way." Sasuke muttered and charged with shurikan and kunai in hand. He threw the shurikan at Haku, who deflected them with a needle, and jumped into the air while throwing the kunai.
As Haku dodged the kunai Sasuke made signs and then the tiger sign. "Fire style: Fireball jutsu!" he shouted as he held his fingers to his mouth and blew out fire.
Haku retreated back into his mirrors and started throwing needles again.
Meanwhile, Kakashi and Zabuza were sizing each other up. Kakashi said, "I can't believe you're working for Gato." He said as he lifted the headband of his eye.
Zabuza chuckled. "He pays good." And charged with his sword. Kakashi blocked it with his kunai, but he knew the kunai wouldn't hold much longer. Zabuza jumped back and started to make hand signs. "Water style: Hidden mist jutsu."
They were suddenly engulfed in a thick mist where nothing could be seen unless it was closer than two metres. Zabuza disappeared. Then a voice was heard. "Heart, brains, liver, lungs, throat. So many ways to kill someone."
Kakashi's eyes widened. The bridge builder!
Sakura was guarding Tazuna when a thick fog surrounded them. "Stay close to me Mr Tazuna." It became eerily quiet.
Out of nowhere, a big sword started to come down on them. In a rush, Kakashi stabbed him in the stomach. The water clone melted back into water. There was a swipe and another sword cut into Kakashi's chest. Then Zabuza backed away into the mist again.
Kakashi looked at the gash on his chest. It wasn't too bad because he leaned back as he struck. "Kakashi-sensei?" Sakura whispered in a frightened voice.
"Don't worry." He replied and touched his right thumb into the blood. He made several hand seals and slammed his hand onto the ground. Then he waited.
Then suddenly heard lots of barking and the mist started to clear away a bit until he could see Zabuza with nin-dogs all over him holding him down.
"What?" Zabuza stuttered.
"You see, Zabuza, I let you cut me so some of my blood could be on you for my nin-dogs to get you." Kakashi said.
Kakashi started making hand seals and from his right hand came a ball of lightning with thousands of chirping sounds. "My Sharingan can tell the future, and your future, is death!" and charged at Zabuza.
Naruto watched as Sasuke was, once again, being pummelled by hundreds of needles. Oh god, Sasuke's gonna "Die!"
The air seemed to explode with chakra, the sheer immensity of it made everyone in the country aware of the great power and shudder from it.
The mirrors shattered and the mist was blown away in seconds. Swirling red surrounded Naruto's body, but instead of covering him, his whole body went dark in the chakra and started to grow.
When it stopped growing it was as tall as a two story house. The chakra seemed to swirl back into itself and it revealed a red fox with black feet and only one tail with a black tip.
The great demon roared in rage. Chakra started to swirl around him again. It looked at Haku with red eyes full of anger. "YOU!" The fox shouted and his tail shot out towards a terrified Haku.
He held Haku in his tail and held him to his face. The fox growled. Chakra surrounded Haku and started burning him. He screamed in pain. But Naruto enjoyed it.
But then something clicked in Naruto's mind. The human part of him was screaming to let him go, but a demon has much more rage levels than mortals and that side of him tried to crush the miniscule human part into nothing.
Then the human part shot back all the memories of being human, of learning from The 3rd Hokage, how he graduated and the team he was put into. Those memories seemed to make the demon side submit and slowly he released Haku who had already blacked out.
Chakra swirled around him as if he were about to transform again but this time it was to change back human. But when he changed back he didn't realise that he used up all of his chakra and he fainted.
Kakashi was charging at Zabuza when he felt it. Power so huge it made him cringe back internally at it. His Lightning Blade diminished, the nin-dogs disappeared and Zabuza was free, if he would at all, but he was staring at the fox that had Haku in his tail.
They both watched in horror as Haku was burnt and then a few seconds later fall onto the ground. They saw Naruto change back and fall limply to the ground joining Haku.
Zabuza leapt to Haku in a second and grabbed her and disappeared into the trees.
Kakashi went to check on Naruto when he heard a shout, "Don't go near it, it'll kill you."
Kakashi turned to see Tazuna had said it. "Don't worry, Mr Tazuna, he's not going to kill me." And continued to head towards Naruto's body.
He knelt down and checked he was still breathing and checked the pulse. Just chakra exhaustion, nothing too major. He lifted his body and carried him while heading towards Sasuke who was sitting on the ground.
"Are you ok, Sasuke?" he asked. "Yeah, just need to get these out." He said indicating the needles. Sakura and Tazuna walked up to them, but Tazuna looked warily at Naruto. Sasuke noticed.
"Ok, we'll talk about this at Tazuna's home." Kakashi said and they were soon headed towards his house with Kakashi piggybacking Naruto.
