Teacher Hayato

Sunagakure.

Currently, the entire village was under attack, by none other than the Akatsuki.

And only two members at that. Sasori, and Deidara. Still, the two weren't to be underestimated.

Deidara took to the skies on his clay bird and started shooting at the sand ninjas and taking them out.

Finally, once the situation was dire, Gaara who had become the Kazekage hurried to come over and stood against Deidara and Sasori on his own.

Deidara landed and the two engaged in a fight under the watch of the villagers of Sunagakure.

"Sand release: Sand binding coffin"

Gaara showcasing his new strength, managed to become powerful enough to even take on Deidara briefly.

In fact, he managed to crush one of his arms as he took him by surprise.

And it was only when Deidara started attacking the whole village that Gaara started to be at a disadvantage.

As the fierce fight in Sunagakure continued on, with the purpose of defeating Gaara and extracting his bijuu, their fellow nearby village had not yet received the news.

And it would be almost too late once they do.

Meanwhile In Konoha.

Three days later.

Sakura with her arms crossed stood next to Naruto who was patting his stomach. Although she may look serious, a small smile graced her face.

'Seems like Naruto is still Naruto…' She was aware he was much stronger than her and that he could have done the test on his own, but he was considerate of her and acted as a team instead. That was pleasing and made her satisfied.

On the other side…

'Ah, nothing more satisfying than Ichiraku ramen…' Naruto had a satisfied smile on his face.

While training, somehow, his teacher used Ichiraku ramen to motivate him to train, and Naruto wasn't sure how he could get it but he didn't care.

The two perked up as they saw Tsunade ready to speak.

"Congratulations, Sakura, Naruto!"

Tsunade congratulated the two as Kakashi had recounted the happenings of the bell test to her.

She was happy for both as one was like a grandchild to her and the other a disciple.

But she was more concerned about a certain someone.

'Naruto mentioned multiple times now, his new teacher… It seems that is the source of his newfound strength…'

Still, she shelved that investigation until a later time, considering the urgent situation.

"Starting now, you are officially team Seven!"

This news put all three, including Kakshi in smiles.

*Sigh*

"Unfortunately, though, we have dire news from Sunagakure!"

**********

Somewhere unknown in the land of fire.

A person was inside a shop, eating Dango from a stick.

'Delicious!'

This guy was wearing regular clothes, a simple black shirt, black ninja pants, and ninja sandals. Above them hung a dark grey cloak.

His black hair was messy, but it only added to his charm and complimented his handsome visage.

This guy was Hayato. Hayato Jiroyoshi.

'Ha!'

He munched on the dango as he enjoyed the taste.

'No wonder that purple-headed snake lady likes them so much!'

He couldn't help but think about a certain ninja from the anime of Naruto who he used to have a crush on. As he was sure many others like him did.

But then, in the next show, she became obese from eating too much sweets…

'Such a waste… ruining such a good-looking woman for practically no reason…'

As for how he had known about the world of Naruto being an anime and how he was currently in it...

'Sigh'

Well, that all had to do with something named the UG.

*Wish*

He grabbed a circular pin in his hands and spun it into the air before it landed on his left palm and showed two letters. UG.

The Universal Gym.

Thanks to this weirdly named system/space or whatever it was, since he was not sure just yet, he was able to transmigrate into this world of Naruto to become its chosen savior.

The Universal Gym chose him to save this world of Naruto specifically. For reasons he has yet to know, nor did he want to. He was a casual person who lived by the moment.

'Universal but not universal…'

Although named universal, it was not limited to one universe but was only named like that according to his guess, since it chose a person from each universe to save the world.

He knew that since he had met Naruto characters inside the Universal gym before.

As for why he didn't know what it was, that was because it seemed like a space with a system managing it.

He could access the UG each time he slept. And once he awoke, he would be fully rested. Meanwhile, he would have spent up to three days inside the gym and only the night would pass in the real world.

Inside the UG, he could meet people from other Naruto worlds or other animes, and he could train. He was not sure why, but he was limited to only the worlds of Naruto and One Piece.

Not that he was complaining or anything.

After all, it wasn't as if he would just train.

Since it was named a Gym… It meant any exercise inside of it was rewarded hugely. Which is why he is quite strong currently. 

Since he had trained for a while inside of it.

'I got here at 18… now I'm 22,'

So that makes it 2 years he trained inside of the gym, and that is by this world's standard of time.

The reason it was two was because he trained Naruto for two years, and by the point he found Naruto, he was already strong enough that the gym's normal exercises did nothing for him.

*Tick*

Hayato discarded the stick of dango after he was done and stayed in place for a bit.

'Life is good… but I wonder how Naruto is doing' He idly thought of his first student in this world.

Naruto was a light in his world the moment he met him.

Don't look at him weirdly.

He doesn't mean anything by that. Only when he was confused and didn't know how to go about saving the world he found Naruto.

Taking Naruto as his disciple was the best thing that happened to him so far.

It solved his problem of trying to save the world since he reached an epiphany.

Naruto is an MC of this world along with many others. Though lesser than Naruto, yet remained as main characters.

Wouldn't taking them as his disciples be the solution to how to save the world? They could be of huge help to him since he couldn't do it all alone.

And that was not all.

When he accepted Naruto, he had to train him for two whole years. Of course, he could invite him in at night into the space, since inside there, one couldn't die.

And since he was a seasoned UG user, he had his own space no one could enter, that was where he trained Naruto. Since it was forbidden for Naruto characters to meet if they weren't chosen ones.

But after Naruto graduated, that same space gained a super-duper ability.

Now, each new disciple of his would get to train for two years, while only one second would have passed outside.

'Such a ridiculous thing… but it made me know that choosing to train Naruto was the correct choice, even the Gym is supporting this,'

Hayato thought silently and then got up from his resting position and started walking after grabbing a sheathed sword that was hanging by the side.

'When will I get another disciple? Sigh…' He had left that up to fate as his part was done. And he was just bored.

As far as his knowledge of the world he was in before… only common sense remained.

He could not remember if he had any family, where he went to study, or such things.

Of course, the knowledge was there, he was just not aware of the memory associated with it.

He didn't mind it too much, however, since he knew by fact that he ah died. He remembered that much at least.

And since he died, he was thankful he didn't meet silent nothingness after that and instead got this second chance, and in none other than the world of Naruto, one of his favorite animes he watched.
