Hidden Emperor Of The Naruto World

In a small clearing, a kid could be seen battling against a green monster...Ah my bad, it was a human wearing a green spandex monstrosity.

In a small clearing, Minato could be seen battling against Maito Dai. Punches, kicks, elbows, knees, he was using all parts of his body with great power behind each blow. Nevertheless, Maito Dai was diverting each of them, and each time pointing a flaw.

With the help of such an amazing teacher and his Hyper intuition, he progressed every day by leaps and bounds. And finally, after months, he more or less mastered his Goken style.

"Yosh! Let's stop it for today young Minato! Your flames of youth truly shine brightly, you have mastered my Taijutsu style in just short months, and thanks to you, I even discovered some flaws in it!"

"Yes! Dai-sensei!" Stopping the spar, a panting Minato was trying to catch his breath, while walking around the clearing to help the blood flow. His regeneration was not all-powerful.

All the training that requires to tear his muscle and repair them are limited. Byron's blood regeneration didn't repair muscles, it's only here to rejuvenate him. And the Uzumaki vitality only repair them far faster than anyone else, but it's not powerful enough to do it non stop during a training. If it was such a cheat, he would have created gravity seals and destroy his muscles while regrowing them indefinitely, earning a super-strong body in no time.

And second, was his lungs. His regeneration didn't apport any more air into it, so he can't run indefinitely without running out of air. His lungs are not on the level of an aspirator yet. He could potentially walk until his death because it only needs a constant level of air his lungs, which is recuperated at the same pace that it burns, but if he wants to run longer, there is no other way than to train his lungs and breathing by running or swimming underwater.

But it's really useful for long battles, he could last longer than his opponents. If the third Raikage had this ability, he would not have died of tiredness during the 3rd great war ninja.

Having recuperated, he walked by to Dai. "Sensei, I have a favor to ask you"

"Oh, what is it? Have you finally decided to wear my spandex? Yoooosh, I knew that my disciple will one day accept it, so I prepared one for your size, here!" Saying that, Dai presented Minato with the jumpsuit.

Looking at the hope in Dai's eyes, Minato's eyes wavered a bit. This guy has been good to him and even gave him his secret technique expecting nothing in return.

"Dai-sensei" Tears gathered at the edge of Minato's eyes, and he began to stretch his hands in the direction of the jumpsuit. Seeing that, Maito Dai was overjoyed! Finally, his disciple has been completely refined by the flame of youth.

"Dameda."(Strong refusal/No way) Minato's face changed from a kid at the edge of crying to one of stony indifference "There is no way I will wear that"

Tears burst out of Dai's eyes like a waterfall "What hip-coolness! I have so much to learn from you, my beloved student!"

Having finished fooling around, Minato came to the point "You know my swift style right" Seeing Dai nodding his head, with some tears still leaking running down his cheeks, he continued "Do you think it could be possible to mix it with your Goken style, adding speed to power?"

Hearing that, Dai made a serious face and began to analyze how such a thing could be accomplished. He never thought for a second that it can't be accomplished, such unyouthful thoughts will not lead him to eternal youth.

"Hm, yeah it could be possible. But it will not be easy, Minato"

Hearing that, Minato was overjoyed! He knew that he could count and Bushy-brow sensei's father. If he had to do it alone, he would have to sacrifice ninjutsu and genjutsu to completely concentrate on taijutsu. But he thought it was strange that this guy thought it was possible even if no one made it before, it's not a thought that people here often have. And so, he asked him.

"Oh, it's because it would need one to master two styles that complement each other to near perfection. And it usually takes tens of years to do that. Not only that, where would you even find another style?" Coming to here, Dai scratched his head a bit

Seeing what he was thinking, Minato continued "Not many are like you and accept to share their techniques is what you want to say, Dai-sensei?"

Coughing a bit to hide his embarrassment, Dai hurriedly changed the subject seeing the starry eyes of his disciple.

"Did you have any luck with the hachimon tonkou?"

Hearing that, Minato made a gloomy face "I was only able to open one gate after all this time. I sense that it was my limit because of my small body, and if I go any higher, I could gravely injure myself"

Listening to this 9-year-old kid saying that he successfully open a gate made Dai jaw drop and his eyebrows pop out of his temple. 'What a youthful genius, opening the first gate after only some months and at such a young age! Not only that, he mastered two taijutsu styles to perfection. Yoooosh, if it's him maybe he could successfully merge two taijutsu style in one and become one if not the best taijutsu master of the world!'

"My youthful student! Let's not waste any more time and begin to work on creating a more powerful taijutsu!" Saying that Dai made an awkward face.

Looking at Dai that was clearly wanting to ask something but seems unwilling at the same time, Minato smiled "Don't worry Dai sensei! If this new taijutsu will see the world, it would be all thanks to you. So, even if half of it comes from me, I don't mind if you learn it. I will even teach it to Gai!"

"Yooooosh! My flame of youth burns even brighter with those words of yours, Minato! Let's fuel them even more with our blood and sweat!"

"Yes! Dai-sensei"

And so, another ordinary day passed at the hidden leaf, with Minato's stalkers cringing listening to such youthful words. Thankfully for young Minato, even if they saw his style, nobody could reproduce it without knowing the workings... or by having a Sharingan. Nor could they know that what Minato and Dai were doing was simply amazing and that the latter was becoming one of the most powerful men in the world...as an eternal genin of Konoha.
