Ok, new chapter everybody. This one has 1 original chapter written by FTDS/Mad Raptor, the remainder is all new content, so, feel free to let me know what you think of it.

The original content is chapter 5, the remainder is stuff I came up with to familiarize you-the reader-with Naruto's skill's while fighting and have a moment between Nagato/Toshinori as I promised last chapter.

This chapter is simply dubbed; Rival

It was mostly an uneventful day.

Three hours until the Tournament, and everything was going good so far.

Other than going around, mostly with Nagato, and seeing the various different people and inventions on display, he really didn't do a lot. Not a lot really called out to him either invention-wise, since while science was cool and all, he couldn't understand any of it if he tried.

Wait, what was that?

'I knew it, he was just like me, he doesn't care for all of these inventions.' Nagato thought with some pride, since he too didn't understand a single thing about all of this science junk.

Science had yet to be able to fix his sickly body, so it had to be worthless overall to him. He was a hero through sheer Uzumaki grit and determination, pushing his weak body as far as he could take it and saving lives with nothing but his Quirk.

"So Naruto, did you bring a suit for the expo party tonight?" Nagato asked, since he had never seen Naruto wearing a suit in his life.

He was curious how his nephew would look in one, he didn't know if Naruto owned one, so he bought an orange one just for him.

"... I like these goggles."

"Hm?" Nagato hummed when he turned his head, and saw Naruto crouched down in front of a girl who had several things lined up on a blanket. Nagato looked at his phone with an event app on it, and he didn't see any people showing off their inventions in this location. Meaning the girl was not part of the I-Expo, and was showing off things on her own, against event regulations.

Which-as a Pro-he knew was illegal.

The girl was matured for a girl her age, though girls matured faster than boys so that wasn't much of a big deal to notice. Long pink hair in dreadlocks, and a slightly athletic/mature build to her, she wore a black tank-top with too much cleavage exposed for a girl her age, and cargo pants. A quirk-feature of cross-hairs around her yellow eyes gave her a zoom-scope like vision aura about her.

"You've got great eyes, this is my 4th invention, my baby here not only allow for night-vision, they can be used to measure people's physical stats, height, other measurements. Here, want to try it out?" The girl picked up goggles that were attacked to a green headband up, and she extended them to Naruto.

Nagato deadpanned.

Naruto didn't care about what the goggles could do, he just cared about the fact that they were on a headband, and Naruto wore headbands all the time. Naruto was almost never without some sort of headband to cover his forehead. The girl had some ankle weights and wrist weights, though they seemed like proto-types, and a few other small gadgets on display.

Did she had a permit to show these off?

Probably not, but who cared?

"Oooooh, I like this..." Naruto tried the goggles on his forehead, and he pulled them down. "Now this is the first useful things I've seen all day." Naruto looked at the girl with the goggles on, and he could see that the invention gave him her height, though strangely enough it was also giving him her three sizes... and damn she was stacked. She was smiling brightly with wide open eyes when she heard him say that.

She grinned with her eyes opened up even wider.

"Well then, why don't you try out this proto-type too... this is my high-density weights, when you wear them, they add half of your weight to your body. Of course, they are only a proto-type, but it would be great for weight training!" The girl spoke in a near-shout, gathering the attention of the people around them who had been ignoring her babies. She grabbed Naruto's wrists and quickly locked the inventions around them, adding a large amount of weight to his arms very quickly as she took his moment of surprise to attack them to his ankles as well.

She stood up.

Naruto stood up too, and started to move his body around.

"Wow, these are really-"

"These babies can heavily assist in the training of any future hero, and help keep a hero's body in shape! When you wear these, they will cause a drain on your stamina by forcing you to exert more force to move! Great for training, small and compact so that they don't get in the way of comfortable movement, and designed with fashion in mind as well! Stylish and useful, just another example of Mei Hatsume inventing genius!" Mei shouted as she used Naruto to show off her inventions. She walked over to Naruto and she pulled up the sleeve of his shirt, and showed off his muscled arms. "See, this boy here has an already impressive body, and even he is showing signs of strain while wearing these babies!" Mei had no problems showing off Naruto's body.

Nagato hummed in thought.

"Nice body Naruto, you've been working out." Nagato complimented Naruto, personally jealous that Naruto inherited a body that could withstand such rigorous training. His own body was so frail that he had to rely completely on his Quirk to be a hero, while Naruto's body was strong on it's own without his Quirk to help him. Naruto's years of training were showing, since Naruto had a Quirk that required him to train if he wanted to be a hero.

"Naruto, care to tell everyone what your Body Fat Percentage is?" Mei asked, hearing his name and using it to further promote her inventions. She picked up another thing off the blanket, and she strapped it to his neck.

"What, wait, what is going on!?" Naruto was just confused, one second he was trying on goggles, and now he was trying out practically everything on her blanket.

"3% Body Fat."

"This baby here is worn on the neck, and it can keep track of your health. It tracks your body fat percentage, your pulse, blood content, and it can be used to observe health in a way that doesn't intrude on daily living, but this is just a prototype so it has a habit of-"

BOOM

Naruto's entire body exploded, much to the crowd's horror as he and Mei were both caught up in the smoke. Naruto's neck was burnt to a crisp, and his eyes were burning red since the goggles had been knocked off his eyes. The left half of Mei's body was covered in smoke from the explosion, while all of Naruto's body was covered. His neck was quickly healing though, steam coming off his burnt flesh as it was good as new seconds later.

"Mei Hatsume correct?" Nagato questioned as she nodded, "You better think about running, you've made him angry, and he isn't afraid to hit girls." Nagato pointed out with an amused smile on his face.

Karin could definitely attest to that with how often they got into a fight with each other.

A tiny explosion like that had no chance of killing Naruto, it would only really hurt him, and pain just simply pissed him off.

"I see, you've got a healing-type quirk, that's super useful for testing out my inventions." Mei didn't read the situation at all as Naruto turned his head to look at her, a growl emanating from his throat.

Why did people always assume he just had a stupid healing Quirk? He did not have a fucking healing Quirk!

She didn't notice his growing irritation with her, but she certainly noticed when he took a step towards her with a fist drawn back. "See, the weights survived the explosion, and now his speed will be cut down severely!" Mei started to run from Naruto as he swung at her, and upon missing, he started to chase her down with a frustrated grunt.

The weights were really slowing him down after all, they worked too, which pissed him off even more.

"You're a girl, so I'll only punch your face a little!" he called out in clear and visible anger.

"You see, he's angry and chasing me at full speed, but with my baby, he won't catch me!" Mei pointed out as she ran at a good pace from Naruto.

She had left her blanket far behind, since this would be a good chance for her to run all around the I-Expo and show off her inventions to as many people as possible. "That's a great idea, Naruto, lets go show off my babies to everyone!" Mei talked to him like he was an old friend instantly.

"I'm going to ram my fist up your ass!" he declared angrily.

"I like your enthusiasm, and the fact my babies blowing up won't hurt you badly works perfectly, lets become partners, so I can test all my babies on you!" Mei offered Naruto as she ran from him. She blinked a little when she noticed his speed increasing a little, which was odd because he should be slowing down with his stamina decreasing, but instead he was getting faster. He was doing the opposite of what her invention should be making him do.

Wait...

Muscles, when they get torn, heal back stronger and more durable, and her invention was strapped to his arms and legs right now.

His quirk seemed healing focused-which it really wasn't-meaning that by adding a lot of weight to his arms and legs, she was causing his muscles to tear and be healed back stronger.

The longer he chased after her, the faster he was going to get until he caught up with her and really did punch her.

Mei turned her head away from Naruto, realizing that her invention had a use that she hadn't thought up.

"I am going to-"

"For those with Healing Quirks, my baby can even up your training and cause you to grow stronger far quicker than other forms of training! You see, Naruto here is quickly starting to catch up to me! In mere minutes, he will catch up to me and beat me up!" Mei pointed out the benefits of her invention to the crowd that she passed by. No longer was she running away from Naruto at a slow pace that he couldn't match, she had to speed up to a jog when he nearly caught her.

Naruto swung at the back of her head, and just missed her by a few inches, causing her to break out in a full run when she realized he was getting way too close to her. Naruto didn't even care to notice he was getting faster, all he needed to do was give her a good solid punch for blowing him up!

People were watching an ash covered teen chasing a teen who was only half-covered in ashes.

"You get back here!"

"See, despite having shorter legs than me and being strapped with a grand total of twice his body weight, since he is wearing 4 weights with half his weight each, he's now catching up to me while I run at full speed!" Mei glanced back with a grin, and saw Naruto was almost within arm's reach of her again. She was about to be in some pain, but she had seen a lot of people with her Quirk, people that were showing interest in her inventions.

That is, until a hand grabbed her by the back of her shirt.

She turned to look at him with slight nervousness, "Now Naruto, you wouldn't hit a girl for real, correct?" Mei asked Naruto as growled at her before he then yanked her off her feet.

She landed on her back, while he cracked his knuckles.

"You're about to hurt."

"I see, everyone watch and make sure you see the wonders of this form of training! Naruto's speed and strength have now been increased by double what his strength was before! In mere minutes, he is TWICE as powerful!" Mei advertised, even as she was about to get the beating of a life.

She would take her licks like a champ, if it meant that she was going to get to advertise her precious inventions more for it.

Time to use her body to increase her fame.

Naruto took off the weights and tossed them on the ground, flexing his muscles and trying to feel how strong he was now. Her words had finally registered in his mind, and curious, he had to know if she was telling the truth. Running around, Naruto did find that he was a lot faster than before, surprisingly.

The blond looked back at the girl, "Still gonna hit you despite what just happened."

-Later-

"You're back." Nagato saw Naruto walking towards him, with Mei holding onto his arm and he seemed a little less irritated.

"-and those are the benefits of you being my test-subject, so how about it, wanna help me in the future? My inventions failing won't kill you, because you'll heal." Mei continued talking with Naruto, after he had walked away from her, she had ran after him. She wanted to get him to agree to become her test subject for her inventions, since it just made total sense.

Her inventions blowing up wouldn't kill him, and nothing she could do to him would be permanent, so it was obvious that he should work with her.

"I'm not becoming your test subject." he declined immediately and sharply.

"How about boyfriend then? You'll still be my test subject, but you get boyfriend benefits. Having a test subject with a good body is a must for any great inventor." Mei was fine with this result as well.

"Boyfriend benefits?" Naruto questioned, he didn't even wanna try to know what that was.

"Holding hands, going on dates, kissing, f*ing." Mei stated, and Naruto wasn't sure if he heard that last one right.

For some reason, it didn't register to him right away.

Nagato's face was a little red at how that one was mentioned.

Mei blinked for a moment, before she realized what had happened, "Sorry, one of my babies is a censor, when it registers certain words, it bleeps them out... I built it as a joke." Mei took a small remote out of her pocket, and she pressed a blue button. "... Holding hands, going on dates, kissing, and fucking... you get all that, for the low, low, price of you being my test-subject... I mean boyfriend." Mei looked away from Naruto when he tongue slipped.

...

"You do realize that the both of you are under the age of consent, correct, and I could have you brought up on charges for even suggesting that to him." Nagato said; though Mei snorted.

"Oh please, the real fun wouldn't happen til we were sixteen. I know I'm to young to be doing that." Mei responded.

Nagato grasped naruto on the shoulder and looked to Mei, "Sorry, but this will have to wait until another day." he told her, "We have places to be, and currently, if we do not go now, we will be late." he stated.

Naruto had a moment to think before he remembered that he had originally come for-the fighting tournaments!

Naruto then looked at Mei.

And then he answered.

~xxXXxx-XxX-xxXXxx~

Nagato Uzumaki was not one who made decisions lightly, not to his work, not for his family and friends, and certainly not when it came to his prized nephew.

That meant he had to find a common ground with the man whom his nephew had decided to call his Master and mentor.

All Might was to recognizable due to the sheer popularity he had garnered. This meant he had to set up the meeting with the man in a secluded spot so they wouldn't be swarmed by fans; yes even Nagato had some fans who were into the more emo variants of Hero work.

He stood on top of the stadium that would serve as the battleground for his dear nephew to fight in the upcoming tournament. The rules for this were very different than normal fights. Seeing as five of the participants were biologically related, the judges had ruled it unfair for Naruto to compete against each of them and opted for a all or nothing fight where each of the competitors would fight it out for first place.

However, Nagato also knew that the wanna-be yakuza brats would team up to fight Naruto in a five on one scenario where he would exhaust himself by the time he managed to get to the final opponent. They couldn't afford anything less than fighting dirty; which in this case was sadly being allowed.

The sound of footsteps drew his attention and he watched as All Might landed on the roof and approached him, "So, you came." he observed.

All Might nodded, "Yes, you mentioned in a message that you wished to speak with me. What is it?" All Might questioned.

"Naruto, for whatever reasons he has, has decided to place his trust in you as his mentor rather than that of Master Jiraiya." he stated, "While I may not approve of you due to your high profile, I am willing to allow him to become your protégé." Nagato told the #1 Hero.

"I had thought that was something that Naruto had decided before you met me?" Toshinori questioned.

"Naruto, yes, me and Granny Mito; no." Nagato informed him honestly, "However, I also know that due to the stress my body is under when I work from my over reliance on my Quirk, I cannot keep watching him as he grows older and prepares himself for a life which has as many cons as it does pros." the elder Uzumaki informed him, "Granny Mito may not have much time left, despite her advanced age, she is still in her 130's nearing her 140's, she is a factor that I looked out for the moment she began raising him as her own when Minato and Kushina died in the line of duty. Karin is actually younger than him, so she is incapable of watching over him when I am inevitably gone."

Toshinori looked to Nagato with a confused look, "I had though that all of you would live to be as old as your Grandmother, you make it sound as if that isn't the case." he stated.

"No, it's not." the redhead answered, "Typically we Uzumaki have high vitality and excessive energy. However, I was cursed with a weak constitution as a child, I am lucky to be alive even now." he said before sighing, "I am trusting you can keep a secret?" he asked as he looked to All Might.

"Yes, I can." the golden haired blond answered.

"I'm dying." Nagato put bluntly, "I don't know how long I have left, don't care really." Nagato informed the surprised All Might, "What I do care about is my niece and nephew. Their safety is all that really matters to me, so I warn you now; if anything were to happen to either of them, I will come back, I will haunt you, and then; I will kill you." he put bluntly, "Don't let me down, you'll live." he stated before he walked away, "Now if you'll excuse me, I have a visit with the doctor, enjoy the fight." he stated as he departed.

Toshinori swallowed the lump in his throat, "I think I just peed a little." he thought to himself.

~XxX~

Toshinori caught up to Naruto in the changing rooms and greeted him excitedly, "NARU-TO! I FOUND YOU!" he exclaimed excitedly as he grabs his student by the shoulder's and shouts boldly.

"Hehe, hey All Might, how's it going; you handle everything you need to?" he asked his mentor.

Toshinori grinned as he allowed himself to deflate, "Yes, I managed to sort everything out with David and he should be coming to attend the tournament to watch you fight." he stated.

"Really, that's cool." Naruto said, only to turn away and sigh.

"You okay, you don't seem pleased." Toshinori noticed.

"It's nothing big mind you, just what the judges decided." Naruto informed the Pro Hero.

"It's a stage fight isn't it, the one on one type?" Toshinori asked.

"Normally it would be, but the remaining opponents I have to go against are all siblings." Naruto clarified, "The judges, in their infinite wisdom, decided to simply have it be a all out brawl between the six of us, the winner takes the victory." he said, "Total bullshit if you ask me." he huffed out.

"So, an unfair match, I could-"Toshinori went to offer that he could speak with the judges to have a normal one on one fight but Naruto shook his head, It's not me fighting them all at the same time that has me worried. I can take each of them on with little problem, it's how it was staged deliberately." the younger blond ground out.

"You act as if you have an issue with that?" Toshinori said.

"Yes and no." Naruto clarified, "Yes in the manner that the Judges did it do mock my parent's, seeing as they're paid off by the people I have to go against and they utterly hate me, except the emo pretty boy." Naruto said, "And the reason I said no is cause I relish a good challenge." he stated.

Toshinori turned Naruto around to face him, "Hey, don't fret, keep calm, and make sure you fight with a level and calm mind." he stated.

Naruto wanted to say that he only would try, but against who he was fighting, it was never an option.

"I can only try." he responded with instead.

"Good, that's I can ask for." All Might stated, "Be safe, and have fun." and with that, he left.

~XxX~

Naruto walked out of the hallway that led into the arena, the cheering of the crowd was a numb ringing in his ears, his focus pinpointed on the five individual's ahead of him as they also exited the opposing end of the tunnel.

He didn't listen as the announcer declared the names of his opposition; could care less how they called him out, he was focused; allowing his senses to move his body.

And soon, he was standing slightly apart from them, his rival standing in front of him as they stood apart from one another.

They were called the unstoppable unit.

Not only for their sheer tenacity and various capacities for fighting; but their Quirks were versatile enough that if they just wanted to; they were be able to simply overwhelm their enemies with virtually no resistance.

All except one.

In order, their names and Quirks were;

*Izuna Uchiha-Quirk Beast of Binding. He could shape the elements of Wind, Water, Lightning, and Fire into the shape of a animal-he preferred using a dragon-to bind his opponents in place to subdue them to allow the other's to beat and wail upon their opponent. He was the cockiest and smarmiest bastard among them. The one thing he hated about Izuna, was the fact he would always be able to piss Naruto off to the point of no return with how he could simply use his words to throw him off the edge-as in enrage him to the point of going punch happy.

*Shisui Uchiha-Quirk Melodic Embrace. The Quirk allowed him to weaponize the soundwaves in the air and use them to subdue his opponent's as long as he gazed upon them. He was actually one of the nicer brother's, but he more often than not put his foot into his mouth. In truth he was actually the weakest of the brother's, seeing as he actually needed a weapon in order to physically channel his quirk in a fight. However, the offset to that was he was more likely to use it as a damn baseball bat if you got to close.

*Kagami Uchiha-Quirk Tundra's Wrath. The Quirk allowed him to use the element's of Water and Wind. He could also supercool the water and create ice; but he was incapable of using it in battle seeing as he had to physically touch you to freeze your body. He could use the power over wind to hover, but he could not fly; the only way he could technically do so was to kick off of something and direct the air currents to push him through the air. He had this particular love of shaping the water he could use into an lance that could super-freeze his opponents.

*Itachi Uchiha-Quirk Eternal Flare. The Quirk was a powerful fire based Quirk, and Naruto had only experienced it in combat one time; and it fucking hurt. The flames were highly condensed and susceptible to grow stronger the longer they physically burned in the air. He was the smartest of the brother's, and probably the second strongest after Sasuke himself. He used a large sword in combat so as to not fall into full demand of using his Quirk in a fight. Definitely the wisest of his brother's that was for sure, and probably the only one that could truly give Naruto a hard time in a fight aside from Sasuke himself.

And finally;

*Sasuke Uchiha-Quirk Stormbringer. The quirk allowed Sasuke to control the elemental power of Wind, Water, and Lightning and even manipulate the weather itself. He had this annoying habit of supercharging his electricity that caused it to ignite similarly to that of fire. He was actually the strongest of the five brothers despite his position as the youngest of them. Oh, and not to mention he could use his power over wind or lightning to give himself the ability to fucking fly like Superman. Much like Naruto; he used a weapon to fight. In fact; compared to Naruto, he could actually be called the better of them, as his rival they had fought and tied more often rather than ensured victory over the other.

The current score between them was 70 fights with 26 to Sasuke, 24 to Naruto with an even 20 draws settled in between.

Though Sasuke suspected that that was going to change soon.

"Naruto, been some time." he greeted.

"Sasuke, I see you brought the welcoming committee." he said as he looked to the silently sneering brood of brothers.

Sasuke snorted, "Unfortunately I had no other choice. It was either this, or we would be wasting our time fighting pointlessly." he remarked.

"So, how do you wanna do this?" Naruto asked, "All together, or one at a time?" Naruto questioned as he looked at the brothers, "I assure you I am more than capable enough of fighting you and yours."

"Heh, if that is what wish, we can accommodate." the youngest brother smirked.

"Good, I don't fancy waiting." Naruto said as his hand was covered in a dark substance in an instant as he launched a powerful right hook that caused Sasuke to shoot back and stumble from the surprise blow.

The one unique thing about this fight-aside from being allowed to show off his capabilities and Quirk, was that nobody aside from Sasuke knew what he was planning.

Sasuke respected Naruto.

His brothers did not.

He admired heroes who protected the people.

His brother's killed them for sport.

Sasuke admired the Habanero and Raijin.

His father's men had killed them...

And his brother's had nearly butchered them...

Only his willingness to steer his brothers away from the bodies were they able to be properly buried with honor.

For Sasuke, this was just as much as a fight for fun as it was petty revenge.

He disdained the underground criminal world, but he lived in it., and for that, he was willing to put even his own brother's in the path of absolute destruction to see his plans come to fruition.

Of him becoming a Hero like the Raijin himself.

Sasuke stepped back behind the approaching four young men whom were his elder brother's, "Naruto," he stated seriously, "your powers are unused to combat." he said in observation, "You should first spar with them awhile." he offered.

As it stood, Sasuke could command the fight how he saw fit; bring in aide or assistance from any other competitor to wear down Naruto's stamina, but he also knew Naruto was far from inexperienced in battle. They constantly had to try and one up the other; it is why they had so many draws in their fights.

He despised Naruto as much as he admired his prowess.

This, he had decided long ago, was the man whom he truly called his brother.

Kagami snorted as he looked at Naruto, "So, the weak little Uzumaki has finally allowed mommy to stop holding his hands, this should be fun." he commented. However, he then perked up and laughed, "Oh wait, you mother died, like a weakling." he said as he and two of his brother's-Izuna and Shisui-began to outright laugh at his now annoyed facial features.

"Oh what's the matter?" Izuna asked him, "Sad that your whore mother can't witness you lose to those whom are better?" he questioned with a mockingly sad pout.

Naruto growled as his anger grew, "You better be careful about you say next, I won't be responsible for what happens to you." he said.

"Aww, he thinks he can beat us in a four on one fight, how cute." Itachi snorted.

"Yea, shame that his weak father can't save him from the beating he's about to receive, it'd be so tragic if he were to witness his son lose so horrendously... but, your father died... like a coward." Izuna said with a grin.

"I'm going to start punching now, you'll forgive me if I don't stop." Naruto stated.

So, if you can't already guess; yes these are the Uchiha clansmen that I have brought in. Now before you ask; yes they will eventually be making a return, but not anytime soon.

*And if you couldn't tell I took some inspiration from the Black Myth Wukong gameplay scene's to showcase the rivalry between Naruto and Sasuke. Now, if you want a formal and easy comparison, here ya go-

1; Sasuke/Erlang Shen

2; Kagami/Vaiśravaṇa (Uses the umbrella in game-has normal skin)

3; Itachi Virūḍhaka (Uses the sword in game-has purple skin)

4; Shisui/Dhṛtarāṣṭra (used the stringed instrument in game-has blue skin)

5; Izuna/Virūpākṣa (Had the dragon and was face slammed by Wukong when he used it-has red skin)
