The lost soul..

Tsunade reared her fist back and with a display of her super human strength she punched Naruto's incoming sword, shattering it into a million pieces. Naruto took it in stride as he used the swing to gain momentum to spin around and deliver a round house kick to the slug sannin.

Tsunade blocked the kick with one arm and pushed him off, Naruto, who had been moving in a clockwise motion now moved counter clockwise. He brought his foot down harshly, digging it into the gravel to stop his momentum as he charged a fist with so much chakra it glowed with blue flames as he slammed it into her gut, using the momentum to add to the impact.

Tsunade felt the air leave her lungs painfully quick, but held her ground and delivered her own punch to the boy's face.

Naruto quickly moved an arm to block as best he could but she broke through his defense like a wrecking ball through plaster as she hit his jaw dead on the spot.

Naruto flew through the air several dozen yards and through a tree before he was able to right himself in mid air and land on the next tree with his legs.

The wood groaned against the pressure of his impact. He used the tree to jump, bounding over the tree tops as he formed his hand seals. Before he cupped his hands infront of his face and breathed out a massive stream of flames towards the woman.

Tsunade reared back her fist and punched the ground, the shockwave of her fist made the earth rise infront of her in massive spikes which blocked the flames. When the orange glow died down indicating the attack had finished she kicked each earth spike/shield sending them flying towards the airborn Jinchuuriki.

Naruto unsheathed his last blade and began swinging, sending multiple wind blade to cut the stones into small pebbles before they even reached him.

As the last stone approached him he used his wind chakra to spin him around, giving him momentum as he kicked the stone back to her.

Only to have it shatter into a million pieces as Tsunade reared back her fist and punched it.

"HAH!" Was Shizune's cry as she appeared behind the man in green, coming down with a brutal ax kick to the junction of his neck and collar bone. Guan took the blow without so much as a flinch before he grabbed the girl by her ankle and swung her around, slamming her into Akina, who had been approaching his side, intent on stabbing him in the ribs with a kunai.

Both girls were sent flying back and skidded to a stop. When they looked back, Guan had finished swinging his sword in an upwards strike, dragging it across the ground leaving a jagged trench in its wake. When the swing was completed, a blue streak of lightning, continued its path forking across the ground towards the two females as it tore the earth apart from the force.

"MOVE!" Shizune yelled as she kicked Akina away and leapt up just in time to avoid the attack.

Akina, though slightly shocked by her sudden movement recovered quickly and rolled in order to get to her feet. She wasted no time and formed her hand seals. "Katon: Ryuuka!" she yelled releasing multiple fireballs towards the green clad shinobi.

Guan placed his broadsword infront of him and began spinning it with one hand, it got faster and faster and when the fireballs finally reached him the speed and wind created by the blade simply dispersed the flames like candle lights.

He ended the spin, falling in a defensive stance, grasping the hilt with both hands the tip of the sword angled towards the floor infront of him.

Akina growled, the sound coming out strangely animalistic for a human before she took out two kunai and rushed him.

Guan waited for her to be in range before he swung his blade horizontally. She fell flat on her back and skidded across the ground, avoiding the blade and trying to kick his feet out from under him.

Guan leapt over her in a cartwheel motion. Akina dug her hands into the soil, stopping herself and then did a perfect backflip while her back was to him, using just the strength of her arm, in an attempt to kick the Kiri swordsman.

Guan blocked both her legs above his head with his forearm and then delivered his own kick, this one headed for the girls chest since she was upside down. Akina placed her free arm in the way in time for it to take the brunt of the attack, the attack still sent her rolling forward, coming to a stop as she slammed harshly into a tree trunk.

Guan turned and placed his sword in the way of several Senbon, Shizune had launched from a hidden device in her sleeve, one look at them and he could tell they were poisoned.

He removed the blade from his field of vision in time to see Shizune's foot before it connected solidly with his face.

He fell back and placed his free hand on the ground. He heaved himself up and kicked Shizune in the chest, sending her staggering back and using her to gain enough momentum to back flip to his feet.

He then turned, swinging his sword in an arc to his other opponent who had recovered.

Akina used two kunai to block the strike as best she could but was still sent stumbling back. Guan turned again to face Shizune, swinging his sword again. Shizune stepped into the swing, wrapped her arm around his holding him in place and delivered a brutal head-but, knocking the Kiri swordsman into a daze just as Akina moved in and stabbed his forearm, making his grip on his sword slacken enough for her to yank it out.

Shizune formed a chakra scalpel in her hand and reared it back in preparation to cut the man's heart. Guan recovered from his daze and caught her wrist in time to stop her. He raised his leg and kicked her off of him.

Akina held Guan's massive sword with both hands, struggling to even lift the damn thing. The blasted hunk of metal weighed a ton to her, just why the hell did these bastards have to carry weapons that were so heavy?

Shizune spoke to her. "You know fire Jutsu right?" At Akina's nod she continued. "Good, take the sword somewhere and melt it, we cant afford to have him get it back and you're no good with that heavy thing weighing you down. I'll hold him off."

Akina looked like she was ready to protest but at a glare from Shizune made her nod and rush off as fast as she could to get some distance between her self and Guan.

Shizune looked back to the large man and took her fighting stance, it was the standard medic Taijutsu stance, strong offence when used in conjuction with chakra scalpel, but weak defense.

Guan recognized the stance and retaliated by taking his own offensive stance. "Do not make me fight you girl, I do not wish to kill you."

Shizune didn't say anything before she formed her hand seals. "Dokugiri" She yelled before releasing a huge cloud of poison that blanketed the area.

Naruto grunted in pain as his back was slammed against one of the tree's, he craned his head to the right just in time to avoid Tsunade's fist, letting it hit the tree and promptly topple it over. Naruto wasted no time and delivered punches to her stomach in rapid succession followed by an uppercut which snapped the woman's head up, leaving her chest wide open.

He reared back his left gauntlet covered hand forming a bright sphere of swirling chakra.

Tsunade' still dazed by the hits couldn't properly defend herself before he slammed the Rasengan right into her chest, sending her flying back spinning with the same motion of the sphere before she hit the floor, skipping over it like a pebble over the surface of a lake before her back slammed harshly against the rock face with a sickening crunch.

She fell to the ground on her hands and knee's one arm clutching her chest as she hacked up torrents of blood. She wheezed when she breathed, the sound coming out strained, strangled and painful. Naruto was almost certain she would die shortly.

Until the diamond shaped seal on her forehead pulsed and purple seals formed all around her body Naruto could hear the bones snapping back into place and hear as organs, flesh tendons, and tissue repaired itself nearly instantly.

The slug sannin stood, green chakra forming a hazy mist all around her she placed her hands in a seal and spoke. "Initial gate! KAI!"

As she yelled out the last word her muscles seemed to expand for a moment before compressing back to their normal size. She then formed another seal, Naruto, knowing that he had to stop this now, before she did any more drew on the kyuubi's chakra and rushed forward at incredible speeds

"Heal gate! KAI!" Her chakra instantly seemed to replenish itself and go beyond what she had even started with.

Naruto unsheathed his blade and pushed wind chakra into it as he cupped his free hand infront of his face mask, his eyes turning red as he began to call on more of the foxes chakra.

"LIFE GATE, KAI!" "KATON: ZUGOKU" She yelled releasing the third gate as Naruto blew out a stream of flames which was immediately combined with the wind chakra in his blade her skin turned red and her chakra output nearly quadrupled, her hair whipped around her wildly, undoing itself from its normal pigtails as she dug her fist into the ground and lifted it up, again using the earth as a shield to block out the flames.

She leapt away just as the ground she had been using as a shield exploded as Naruto tore through it like rice paper, two claws of red chakra rushed out of the dust and debris, they grabbed her roughly by the shoulders and began to burn her terribly, only to for her to replace herself with a log.

Naruto spun around in time to dodge Tsunade's axe kick, he stumbled as the earth shook and gave way beneath him as her foot connected. Tsunade took the opportunity it presented, grabbing him by the collar of his cloak, she reared her fist and punched the blond Jinchuriki as hard as she possibly could, pieces of his cloak were torn off and gripped firmly between her fingers as the blond was sent flying, slamming into the rock face hard enough to have it crumble ontop of him in a small land slide.

Everything was silent for a moment before Tsunade heard a deep growl as red light could be seen between the cracks of the earth piled over of the Jinchuriki.

The very earth began to shake and Tsunade felt a brief moment of fear before she smothered it completely. She moved rushed forward, intent on killing the boy before he could finish whatever he had planned.

She didn't get more than two steps before hundreds of red chakra claws exploded from the ground all around her, They rose into the air, going far beyond the trees before they came crashing down on her like a great tidal wave of bloodlusting power.

Tsunade dodged as best she could, using her enhanced speed to help her, but even she couldn't keep up with it and soon received three gashes from her left shoulder to her right hip as one of the claws slashed her. Then another slashed her across her back, then another and another, the slashes healed almost as quickly as they appeared but they still caused terrible pain even after they were healed.

When the chakra claws ceased their slashing and instead formed into one huge mass which began burning her whole she did the only thing she could think of.

"KUCHIYOSE NO JUTSU!"

A massive cloud of smoke blanketed the entire forest and the next thing that was seen was a massive slug.

Tsunade gasped in relief.

"Tsunade-hime!" The slug spoke taking in her state. "Are you allright?"

Tsunade didn't have time to answer before another cry was heard.

"Kuchiyose no jutsu!"

Another smoke cloud, this time revealing.

"Manda!" The slug seemed to hiss out the name like a cursed poison.

"Katsuyu." Manda snarled and then looked at his summoner, who stood atop his head, only this time, his cloak was missing from his shoulders, revealing his bright blond hair as his red eyes glared at the medic with as much contempt as he could muster, two flaming red tails of chakra thrashed behind him.

Naruto looked to the snake and spoke. "I want them in pieces."

Manda smirked. He was going to enjoy this.

Shizune charged the shinobi, as she got in range she attempted a spin kick only for Guan to duck under it with ease, she then followed it up with a sweep kick, but he dodged that one as well.

She would have attacked again, if the air hadn't left her lungs as the man slammed the back of his fist into her ribs with an air of effortlessness about him.

Shizune, uncharacteristically cursed before she attempted to back hand him in the face.

He caught her fist and twisted her arm behind her back, Shizune craned her neck back to be face to face with the older ninja.

Guan barely had time to catch her smirk before… "Fukumikuchi Hari!"

The green clad man screamed and punched her hard in the face as three small needles stabbed his left eye. He fell to one knee and held one hand over his eye as it bleed freely.

Shizune smirked wiping some blood from the corner of her mouth as she stood. Those needles weren't poisoned due to the danger of having them hidden in her mouth, but they had served their purpose.

She moved fast and charged the larger man, coming in with a flurry of kicks and punches, Guan couldn't defend properly due to the fact that his eyes naturally tried to follow her movements, causing him even greater pain as the needles scrapped against the inside of his socket.

Shizune then broke through his guard and used chakra scalpel to cut the tendons in his left arm. With a cry of rage the older man took out a kunai and with speed brought on by pain, and anger he plunged it into her stomach, causing the woman to stop and cough blood.

Before she could do anything he left the kunai in her stomach and then kicked it in deeper, burying it up to the hilt and making her fall onto her back as she coughed up more blood.

Guan again fell to one knee. He took out another kunai and looked at it with his one good eye. He looked momentarily torn before his features hardened.

Shizune watched in horrified fascination as the man plunged the kunai into his own eye and cut it out, blood sprayed everywhere, it fell down the left side of his face freely, caking his beard in the red liquid as it pooled at his feet.

She got to her knee's and with a forceful pull took out the kunai from her stomach. She groaned as she threw the bloody weapon away and took deep breaths in an attempt to help concentrate on healing the injury.

Guan also took deep breaths as he began tearing off some of his robes and used them as a makeshift bandage to cover his eye. Finally after almost a minute of regaining his composure he stood and began walking over to Shizune's prone form who was almost done with her healing, but not quite finished.

He stopped infront of her and stared into her eyes, they held fear, but also determination and anger, both things nesesary for a ninja. "Not bad, young one." He admitted before he kicked her.

Shizune managed to cross her arms infront of her in time to block the attack but was still thrown back, several feet by the force of his blow.

Guan moved to step forward again before something crashed into his side, nearly tackling him to the ground.

He regained his bearings in time to see the snarling features of the other girl.

He leaned his head to the right dodging her fist, which held surprising amount of force, before he lifted his leg, placed it on her stomach and chest and pushed her off.

He stood and watched as the girl righted her self in mid air and landed, her form hunched over as her hair covered her eyes. He could tell that something had changed about her.

Katsuyu's form seemed to bulge for a moment before she released a huge stream of acid towards the snake, hitting it dead on.

When the snakes melting form could be seen clearly it revealed nothing but its shed skin.

Manda exploded from the earth behind the slug, wrapping itself around it, only to have Katsuyu separate into hundreds of other, smaller slugs and reform out of its grip.

As the slugs reformed, Naruto realized…

'Tsunade isn't on her head.'

He barely turned around in time to see Tsunade's form as she ran up Manda's back, heading straight towards him.

He ducked under her fist, then placed his right shoulder against her stomach and grabbed her extended fist with his left hand. He flipped her over his shoulder, sending her clear off Manda's head.

He did not however, expect her to grab his collar and pull him down with her. Sending them both spiraling down to the forest floor.

Both were snarling as they continued exchange fists and kicks in mid air, each block and impact hurt both of them, Such close proximity was burning Tsunade terribly, at this rate her seal of rebirth would only last for about another two minutes or so. And each blow Naruto blocked would still break the bones in his arms, only to have them heal in seconds due to the foxes chakra. Only difference between them was that his source of healing was virtually endless, while hers had a limit, he would outlast her, then he would kill her.

'Not again' Was the mantra the young blond haired girl chanted in her head as exchanged attacks with the Kiri Shinobi. She swerved to the left to avoid a downward swing he delivered with his kunai.

She extended her left arm and placed it over his neck in a headlock which made him arch back. Then she took her right arm and wrapped it around his extended arm so his elbow was against her rib cage she then pulled hoping to break his arm.

Guan grunted and grit his teeth as he fought against her hold, then using a burst of chakra he broke free, elbowing her in the stomach and then backhanding her in the face, sending her sprawling.

She hit the floor hard but rolled to her feet, she snarled on all fours as she glared at him, and then let her eyes travel to the falling figure of Naruto as he fought with Tsunade.

'I wont let you win again.' Was her silent promise as she closed her eyes.

When she opened them again, they had changed from her clear blue, to a deep crimson red with an animalistic slit...

Naruto caught Tsunade's fist and reared his claws back, ready to tear her apart, but suddenly he felt pain, deep burning pain as if he had unleashed four tails of Kyuubi's chakra. The red chakra shivered and seemed to fade for a moment before it exploded everywhere, changing from a focused two tails to a hazy cloud of red chakra.

Naruto bit back a scream of pain, Tsunade again seized the opportunity and reared back her fist, punching him again and sending him flying down to the earth.

He flipped in mid air and landed on all fours, a massive dust cloud picked up in his wake He tried to stand but fell to one knee and gripped his stomach, over the area where the seal was. He hissed in pain. Gritting his teeth he opened a single eye and for the first time in a long time, felt true surprise.

There infront of him, was the girl Tsunade had called Akina, hunched over like an animal, a single red chakra tail whipping behind her. Above her, the head of a fox formed from the chakra.

It looked straight at him, piercing his red eyes with its own before it smiled darkly.
