So here is the new chapter. They only have two fights as you already have figured out, so no fight with Sasuke yet. This chapter is the match with Sai and Sakura and some other things scattered in between.

I hope you enjoy.

Necessary Evil

Unstoppable

Naruto Uzumaki v/s Sai Begin

There was no conversation between them as they didn't know each other and the fight started immediately.

Naruto dodged the ink lions as Sai had taken to the sky on his ink bird. He slammed his palm on to one of them and the lions exploded into a shower of ink. Surprisingly, not one drop fell on Naruto.

Naruto narrowed his eyes as he saw the ink seeping into the ground but had no time to ponder on it before another lion attacked him.

Sai made more ink lions from on top of his bird and they jumped down to the arena. Naruto narrowed his eyes and made ten clones. All of them began tearing apart ink animals.

"That boy is planning something." Onoki said looking at Sai who was hovering above the arena.

"Indeed, but what?" Ay asked.

"That ink, it is seeping into the ground and just disappearing! It's some kind of trap." Kurotsuchi said.

"I have a bad feeling about this" Gaara said looking down at the arena.

"Well, you are not the only one." Kyoshiro, who had appeared back inside the kage box, said.

It's over for you now boy. Danzo thought smirking down at the arena.

Naruto narrowed his eyes at the ink animals that began melting into ink on their own. He stepped back suspiciously as the creature he was fighting, too melted down.

What are you planning? He thought, looking at Sai who was now at a visible height.

The ink had all vanished into the ground. Something about the whole scenario unsettled him.

Suddenly there were seals all around him. They appeared quickly as the ink suddenly began streaming out of the ground forming strokes of kanji. Naruto couldn't get a good look at the seal since it was massive and he was trapped in the center, but he did recognize the kanji he did get a look at and had a good guess what the seal was for.

The Seal array began to glow and soon it was glowing a bright red color.

Naruto felt the seal immobilizing him and draining his chakra at a steady rate. He wasn't worried about chakra depletion simply because he had so much chakra that he knew the seal would get overpowered and blow up. But that didn't mean he would be careless, nor would he let the people find out that particular detail about his chakra capacity. He would need less than a quarter of his chakra to overpower the seal, but overpowering the seal meant people getting an idea of how much chakra he had, because the chakra needed to overpower the seal is well past any human's limit.

The clones all began popping one by one. The entire arena was now one gigantic seal array with the original Naruto trapped inside.

Naruto struggled for a minute then calmed down and observed the seal more, a suppression seal capable subduing even a biju if only for a brief period of time and the chakra draining seal, containment seal… the list goes on. At best, the seal could take out a five-tailed-biju. Impressive but not good enough.

Naruto began looking for that one particular seal that would be Sai's downfall.

Everyone was looking at the arena in awe.

"Sai knew sealing!" Sakura exclaimed looking at Kakashi and Sasuke. Both of them didn't answer her and Kakashi discreetly eyed Jiraiya.

Jiraiya looked pensive knowing what was coming next. It was his seal that was going to be Naruto's downfall. He was both relieved and guilty at the same time. He looked over at Tsunade who refused to meet his eyes but he knew that it was guilt that was consuming her. The way she grits her teeth to stop herself from shouting out at the unfairness of it all.

He closed his eyes, it was unfair and he knew that. He knew that better than anyone. After all, he was the one who gave Minato the fucking idea to use his kid as a jinchuuriki; he was the one, who convinced his student that his son would be the Child of Prophecy, he was the worthless godfather that abandoned his godson for twelve fucking years and after all that, he was the first one to give up on Naruto when Sasuke accused him. And he knew he didn't even give the kid a chance to explain just because the Prophecy had changed. The toads told him that the Prophecy, the fucking Prophecy that he sacrificed everything for had changed. Naruto was no longer the Child of Prophecy that would save the world because there might not be a Child of Prophecy, to begin with. Wasn't that just great?

And who paid the price for the change in the Prophecy? Naruto did. Jiraiya took his anger out on the kid that didn't even have an idea about the Prophecy, wasn't that the noblest thing to do?

Now after all the crap they had put the kid through his village wanted him back and Jiraya was helping his village. Maybe it wouldn't hurt so much if he didn't know that they were cheating. No matter how many times he told himself that cheating was part of being a ninja, he couldn't help but feel guilty. Naruto was set up for a failure from the beginning.

"Jiraiya…"

He turned to look at Tsunade who called out his name.

"I am forfeiting."

Everyone present looked at their kage with wide eyes, "Sensei, what the hell are you talking about now?" Sakura shouted.

"I can't-"Tsunade looked down and all of them saw the tears brimming in her eyes. Jiraiya felt like he couldn't even face her anymore.

"I can't do this… He is my… I just can't"

"Tsunade" Jiraiya spoke sternly his face set in a grim expression, "I believe that forfeit is not an option for you."

"And why the hell is that?" She turned enraged eyes to him and Jiraiya ruthlessly squashed the urge to shrink away from her fury and most of all, her pain.

"You're the Hokage of Konoha; your defeat means a lot more than just the loss of your inheritance and money. It means the loss of Konoha. And you can't do that to your village."

Tsunade laughed and it was a bitter, broken sound that all of them cringed, "My village! My village!"

She laughed again and some of them were worried that their Hokage was losing it.

"The person who made this my village is fighting against me and 'my village' right now Jiraya." She might as well have roared it out for all the impact those silent words had.

"If Naruto could convince me once to join the village I swore away from and to take up a position I despised then he doesn't need words to convince me to give it all away."

Everyone looked at her outraged.

There were protests all around but Jiraiya remained silent. Finally, he spoke,

"What if he loses? What if he loses and you aren't here to be his Hokage?"

"He'll win," Tsunade said with conviction. Why was she defending him now? She thought. She had chances to defend him earlier, so why was she doing it now? Because earlier she believed that if Naruto would just come back to the village they could fix everything. Fix their broken relationship into something similar to what it was before all this. But then everything went out of hand and she forced herself to believe that this was the right path.

But every interaction between Naruto and his past friends during the matches proved her wrong. Whatever they had before was ruined; dead and this course of action was only mangling the corpse further. In the end, their words hit home and her lies that kept her from seeing things clearly were ripped away.

Hanabi was right. If Naruto ever comes back to Konoha, a guard dog is all he'll ever be. He had a life out there, a family and that thought hit her hard because once upon a time she was a part of that family. With all these realizations came a kind of numbness that she couldn't push away. She wished that she had a bottle of sake with her. That's the only way she knew how to deal with all this.

Jiraiya's words brought her out of her depressing thoughts and his tone and the look on his face set off warning bells in her head.

"He won't," Jiraiya said with enough conviction to match his blooming guilt.

He has done something, her mind warned. She gave Jiraiya a suspicious look, "What did you do?"

Jiraiya was silent.

Impossible, Naruto thought. Sai shouldn't have enough chakra to maintain this seal. His eyes narrowed.

Already the seal had drained about half a tail worth of chakra, it was no big deal to him but he wasn't going to show it. Half a tail worth of chakra was a big deal for all normal ninja and people shouldn't be finding out just how 'normal' Naruto is.

'And the seal… Unless Konoha had a new seal master all along there is no way that Sai could manage this seal without help'

Of course, Sai had help. Naruto was no fool and he could recognize the work he was seeing for who made it.

Naruto leaned down on one knee just for show and grunted like he was in pain. Maybe he should try acting as well since he is so good at it. There were gasps from his fans when he went down and applause from the Konohans.

Naruto suppressed a smirk as he spotted the seal he was looking for.

'Times up, Sai'

Biting down on his thumb he broke the skin and stopped his healing from interfering with the flow of blood. He bought the bloody finger to the ground.

One stroke, two strokes, three and four.

Sealing was such a delicate art; a single stroke can mean a lot of difference.

The Restriction seal that had kept Naruto trapped in the seal had been disabled. Not wasting any time Naruto started running towards the seal he spotted.

In a moment he was crouched down next to the Master seal which was basically what kept the entire seal array together.

"What's he doing now?"

Jiraiya's eyes narrowed while everyone else looked at the display with curiosity. Tsunade was giving him an accusing look and he knew that she had figured it out.

The entire stadium was rigged from the beginning. And Jiraiya was the one who did it.

Sai looked down at what Naruto was doing, he had managed to get freedom of movement within the seal and that was not good. But it wouldn't be long before that Naruto was entirely drained and it wasn't like Sai could do anything. He cannot attack Naruto without risking the seal array absorbing the chakra he used to create the attack. And Jiraiya-sama and Danzo-sama had warned him not go anywhere near the seal array once it was activated so he had nothing that he could do but watch.

As he watched, Naruto finished whatever he was doing and stood up. Unease made itself known when he noticed that Naruto looked entirely too smug.

Naruto made some changes in the Master seal and stood up more relaxed. He looked up at the hovering Sai and gave a smirk.

Everyone was watching with baited breath to see what would happen.

Jiraiya cursed when the seal's glow died down. He felt a tug at his chakra and his eyes widened when the array began glowing again, but this time it was brilliant white in color. So white that it was almost blinding.

Jiraiya panicked when the tug on his chakra became more forceful. Naruto reversed it! He reversed the fucking seal!

Without giving it a second thought he tugged back his sleeves and pulled out a kunai. In his inner wrist, there was a seal, the seal that connected him to the seal on the arena. He quickly slashed the kunai through the middle of the seal then used his blood to draw a counterseal.

He sighed when the tug vanished but looking down at the arena he could see Naruto shaking his head.

Jiraiya knew that disappointment was meant for him. He had failed once again.

All around him the ninjas present gave him varying looks. He pretended not to see the understanding that dawned on their faces and the contempt on Tsunade's. But ignoring it didn't make it disappear.

Naruto smiled ruefully. He knew there was something strange about the stadium from the beginning but he couldn't figure out what.

The base for the seal had already been set up before the matches. Sai only initiated it; it was controlled by Jiraiya and powered by the chakra storage tanks beneath the arena floor. He hadn't paid much attention to the chakra storage tanks because they had been always there. They would absorb any residual chakra present after each fight and the collected power would be stored away for later. This had been how it was since arena was built.

'I guess defeating me was an emergency'

It wasn't fair, he knew that. Ninjas never played fair and that was just one of the things he hated about his once profession. He was planning on being nice but if this is how they want to play he don't mind.

He crouched down and put one more stroke on the Master Seal. The white glow turned blue.

Jiraiya had cut himself off from the seal to save himself but the fool either forgot or thought that it would be fine to leave the connection with the storage tanks intact. Now there was nothing between Naruto and four tails worth of chakra stored beneath his feet.

"Hokage-sama"

Tsunade turned her glower on to the poor fool who had come with some urgent message.

"What?" She snapped.

"Hokage-sama our chakra storage tanks are being drained, we have already half of the stored chakra and is steadily losing more as we speak." The chunin messenger was shaking from the wrath of the Kage. But then Tsunade laughed. She laughed so hard that tears sprung from her eyes. It was all so funny to her. They were going to fail and it made her happy to know that.

She turned to look at Jiraiya who had paled like he had seen a ghost, "Didn't think that this could happen, did you?"

"He's absorbing the chakra from the storage tanks" He whispered horrified.

The original seal was supposed to absorb Naruto's chakra and add it to the Storage tanks but now that Naruto had reversed it, the seal was taking chakra from the tanks and giving it to Naruto. The seal was only a backup plan. When Jiraiya had planted the seal with Danzo and the council's knowledge and help, he really didn't believe that Naruto would be strong enough that they would need to use the seal. But Danzo had pushed it, saying they needed a backup plan and Jiraya had agreed. Now their back-up just backfired on them.

Jiraiya turned aghast and looked down at the stadium.

"How much chakra was in the tanks?" Sakura asked worriedly.

"Almost four tails worth of chakra." Tsunade said smirking amusedly, "Had it been anyone else than Naruto their body would've given out at the stress from that much chakra but not for him. He is an Uzumaki and was a fucking jinchuuriki to boot; his body is adept at handling more potent chakra at a larger level. Four tails worth of normal chakra like this isn't anything compared to an equal amount of biju chakra. So the worst that could happen to him for taking on this much chakra would be a slight falter in his control."

Naruto was glowing with the power he was absorbing. Jiraya cursed, this couldn't be happening. The seal was supposed to drain and defeat Naruto, now it had made him more powerful than when he had begun with.

Another messenger came a second later to inform them that their storage tanks were completely empty and in the background Jiraya could hear Tsunade's chuckles. But his eyes were fixed on Naruto who was smirking at him with a vicious twinkle in his eyes and even from this distance Jiraya was sure of what he saw.

Naruto took his eyes off of Jiraya and turned to look at Sai who was hovering unsurely. He had no idea whether it was safe to be within the range of the seal or not.

Soon once the storage tanks were empty, the seal gave one final glow and it died down.

Naruto chuckled, since he absorbed some extra power showing off didn't seem like a bad idea.

Sai had no idea what hit him before he was wrapped up completely in golden chains and was pulled down to the ground. There was a crater where he fell.

Naruto moved closer to the struggling man. Of course, there was no way of getting out of the chains even Hiraishin wouldn't work once you're trapped in them. That's what made the Uzumaki chakra chains so infamous. Once you're caught, it means you're trapped with no way out unless you can break the chains with a physical force which was also very hard to do.

He didn't waste any time. Moved one hand to the struggling man's forehead and Sai passed out screaming like all others.

Winner: Naruto Uzumaki

The medics were quick to remove Sai from the arena. Everyone was waiting with baited breath for the next match.

Sakura stood with the other shinobi waiting for her match to be announced.

"Sakura" Kakashi called and she turned to look at him.

"You won't be able to win this one like this."

"Sensei you-"Her protests died down when Tsunade scoffed at her.

"He is right, girl. Maybe you should just forfeit."

Sakura turned her glare on to the woman who had taught her and shrunk back when the woman glared back.

"That was not what I was trying to say," Kakashi said and Tsunade turned to him with a raised eyebrow. He continued and this time looking at his Kage and Jiraya.

"We need to regroup and come up with something new. We have no idea what he had done to the others and so far from what we have seen all he needs is a single touch to cause damage. We need more time." Kakashi said. From the side, Sasuke scoffed and the others frowned thoughtfully.

Tsunade looked irritated by the whole thing, "We don't have any breaks planned between the matches. You all should know that, since it was your fucking idea that the continuous matches would tire him out. And now you want a break? Well you can go suck a dick, asshole"

Some of the shinobi looked scandalized at the Hokage but Tsunade only smirked. Jiraiya frowned but he knew that Kakashi was right. Naruto reversing the seal (not just any seal, it was Jiraiya's masterpiece) means that he is at least at Seal Master Level in sealing. But the ease with which Naruto had reversed the seal meant more than a Seal Master Level.

Kakashi scowled under his mask. The matches had started at 10 AM and now it was close to 11 AM.

Naruto took barely one hour for defeating nine opponents in one-on-one matches. Surely the rest of them were stronger than the first nine jonin but it didn't mean much if they went in blind. Not to mention that the amount of chakra that Naruto absorbed meant more trouble. The chakra had formed a translucent blue layer around him and it was cackling like lightning and churning like violent waves. This was not good for them at all.

They needed time and their kage was not listening.

"Tsunade-sama you need to-"

"I am not announcing for a break Kakashi, you can forget about it."

Kakashi turned grim and looked down to the stadium just as the match was announced.

Sakura went down to the arena without another word.

'Having fun?'

'Of course' Naruto raised his head to look at Kyoshiro. He heard a chuckle resounding through their link and he smiles back.

'He agreed to the meeting'

Naruto hummed thoughtfully, 'We should be prepared…'

'You sure this is what you want to do?'

'What I want to do, Kyo? What I want to do is rip his head right off his shoulders… But this is what I need to do… for Jiji at least. Else that poor soul might never find rest.'

Naruto felt Kyoshiro trying to calm him down through the bond and smiled softly.

'There is also something else.'

Naruto became curious, 'what?'

'A child you might want to take a look at'

Naruto frowned thoughtfully, 'A child'

Just then the next match was announced.

Naruto Uzumaki v/s Sakura Haruno Begin

"Sakura-chan" Naruto greeted in a mockingly cheerful tone.

Sakura scowled, "You have no right to address me like that; like we are friends"

Naruto raised his eyebrow and then nodded with a smirk, "Alright them Haruno-san, shall we begin?"

Sakura answered with a resounding strike to the ground and earth crumbled beneath her fist. Naruto jumped up gracefully and retreated to the other edge of the stadium.

Sakura was with him in a matter of moments but Naruto dodged all of her attacks easily. She wasn't surprised as she saw how Naruto dodged Hanabi's attacks earlier. His speed was beyond her and she had no hope for matching him in speed. Yet she kept on trying to land a punch on him and distract him

Naruto was amused. Sakura thought that he was distracted enough to not notice how she had slipped down those explosive tags.

Moments before the first explosion, Naruto had vanished.

Explosions rocked the arena and Naruto watched from another safer part of it. Sakura appeared behind him ready to punch his brains out.

He turned around at the last minute and all the shinobi who knew the strength of the frontline medic froze.

Naruto caught her fist in the palm of his hand nonchalantly. He wasn't even straining, just stood there with that nonchalant pose and Sakura's fist firmly caught in his palm.

Sakura's eyes widened, "Naruto! How?"

"That's Uzumaki-san to you, Haruno-san or you can call me Namikaze-san. After all, we're not friends."

Sakura almost didn't notice his other hand until it was too late, but she dodged at the nick of the time.

This time, Naruto went on the offensive. But Sakura knew without a doubt that he was holding back and even then she barely escaped with her neck intact. Naruto was playing with her that much was sure.

Her mind raced to find a plan but Naruto was slipping out of all her traps very easily. He countered her strength and taijutsu like she was just an Academy student.

Sakura aimed another punch and all it did was destroy more of the stadium. Naruto was nowhere to be seen.

'Where did he-'

Her line of thought was cut off by a sharp punch to her spine from behind. Sakura choked out a cry and she could feel her vertebrae breaking like twigs under the force of the punch. Another kick was placed at the back of her head and pain radiated through her entire body as her skull cracked under the impact.

Sakura was too stunned to stop another punch to her chest that took out at least four of her ribs. She crumbled to the floor as her body could no longer support itself.

"Come on Haruno-san we both know that this means nothing to you"

Naruto was standing in front of her and he was right. With a glare and a pained grimace, Sakura focused on her seal.

'Yin Seal: Release'

The injuries vanished within the second. Sakura grimaced this time in irritation; it didn't take even few minutes of the match before she was forced to use her seal.

She looked up and saw that Naruto was smiling at her. She growled and moved forward.

Punch. Dodge. Kick. Dodge. This continued on for some time with Naruto landing too many punches too often.

Sakura staggered back when Naruto managed to land a blow once more.

It didn't take her long to figure out that if it hadn't been for the Instant Regeneration she would have been nothing but a bloody piece of meat by now.

Then all of a sudden Naruto stopped, he had indulged her long enough. Sakura too stopped warily gazing at Naruto who was smiling at her patiently.

"So Haruno-san I believe it's time to end this"

Sakura's eyes narrowed, what's he planning? She cursed herself for not getting some more ninjutsu in her arsenal. She had concentrated on her physical strength and medical jutsu, both of which were not really useful in this situation.

The coat of chakra that was swirling around him began concentrating around his palms in something similar to the chakra scalpel and covered up to his forearms. Sakura concentrated and activated her own chakra scalpel. And their match resumed.

What happened next was brutal.

This time, Naruto was even faster, his movements more precise and aiming for maximum damage. Sakura soon found out that unlike her chakra scalpels, whatever Naruto was using was shredding her muscles and nerves like wet noodles. They were aimed especially on her nerves. It was so much damage that she knew the Instant Regeneration technique was only barely managing to repair the damages.

Panting and at a loss of what to do, Sakura stood to stare at Naruto in utter disbelief. She thought that she had a good guess on his abilities, then he goes and proves her wrong by going even beyond what she already knew. She resumed her fighting stance and got ready to take off, but then something went very, very wrong.

All of them were silent as they watched the scene. Tsunade was the one who broke the silence with a chuckle.

"One of my greatest techniques" Tsunade laughed wholeheartedly, "And he managed to surpass it"

Tsunade was smiling unlike everyone else with her.

"Guess he surpassed the both of us already, huh Jiraiya?" She didn't bother looking at Jiraiya, her eyes stayed fixed on the arena.

Jiraiya stood behind her scowling, her words weren't meant to be comforting and Jiraya was none too happy to hear them.

Her whole body shook and she stared in wonder at her arms. She couldn't muster up the horror she needed to feel and only stared surprised at the stream of blood still leaking from the multiple cuts on both her arms.

She was bleeding. She was bleeding and she knew that her Instant Regeneration was still in effect. She stared at it for some more moment, willing the cuts to stitch back together, but no, her chakra was directed for the more extensive internal damage she noted duly. Her chakra was still trying to fix the mangled nerves that were a result of Naruto's strikes and if the worsening shaking and the loss of feeling in her legs were any indications, her chakra wasn't doing a very good job.

Sakura numbly turned to look at Naruto as her body shook harder and she crashed on to her knee.

He was now standing right in front of her.

Would he leave her alive like he had done for the rest of the opponents or would she be an 'exception'? Her career was lost; she knew that at a base level. Extensive nerve damage meant that she would never have a steady hand or the immaculate chakra control she priced even if managed to heal and live. There would be no unscathed escape.

Naruto raised his right hand the chakra still covering unto his forearms and her eyes took in the sight of minute blades of chakra that moved like raging waves over his arms. She closed her eyes and waited for the finishing blow and hoped that he made an exception and was about to end her. Without her career; her purpose, it wasn't worth living.

But the blow she expected didn't come and instead two fingers grazed her forehead.

Startled, she opened her eyes. There was no pain like she had expected, not that she thought she could be in any more pain than what she was already suffering through and she fell down to the ground completely, eyes falling shut.

Winner: Naruto Uzumaki

Tell me what you think of this chapter and if I make any mistakes like the one in last chapter where I typed Kyoshiro Kazama instead of Kyoshiro Kurama. I seem to be making these types of mistakes often and which is why I am in desperate need of a beta. I haven't found one yet so you guys will be suffering more of my idiocies in the future till I find myself a beta.

I am so sorry for any mistakes, I do try my best at editing but some facts just skip my mind when my concentration is split between too many stories, like what I did with the Kyuubi's name. Kyoshiro Kazama is the Kyuubi's name in my 'Inari Blessed' and I got it mixed up with this one. Mistakes like these slip past easily. So don't be too angry please and if you point out the mistakes I'll try to correct them.

Sincerely,

Iris Evergreen
