Huge amounts of dust filled the air, revealing a rocky terrain filled with uneven holes. A single man lay there, right next to one of the bigger and more circular of the holes. He had finally made a decent rasengan.
He would have laid there forever, (chakra exhaustion is a bitch) but a toad with a kanji for 'fire' on his back appeared from nowhere and started calling him.
Minato groaned to himself, out of all the times to receive a personal summon from the hokage...
He got up, brushed himself of, and walked to a nearby bench where he had left his chunin vest. Gobbling down a chakra pill, he nodded to the toad, and they both disappeared in a puff of smoke.
--
Hiruzen grumbled to himself as the jonins filled the room, some out of swirls, some out of summons, while others via the door. He had to make a more efficient way to gather them.
"Good afternoon everyone. You have been called to meet your new B-rank assignment for the next few years: genin teams." He said, causing many of his 'professionals' to start complaining like a a bunch of kids. "I have already decided the teams, you are all just here to 'accept' them."
Silence. Everybody waited with anticipation for his announcement.
Minato hummed to himself as he thought: there were about 40-something jonin in the room, and (usually) around 30 academy students; all genin would be made into a team of 3, meaning that there would be 10 new teachers as of today,meaning that he has 1/4 chance of more responsibilities...he had faced worse odds in the past.
Names started getting called, one by one and Minato smiled, looks like he wouldn't be getting called after all-
"Namikaze Minato, team 7"
-or maybe not. He walked up to the academy instructor with the other jonin and got basic information about his team: names, gender, age, basic personality info, etc.
"You will meet your team in an hour" called the hokage. "Dismissed, except for you Minato."
Everybody else left the room, leaving him alone with the hokage. Minato patiently waited for him to speak.
"As you know, you will be assigned to the front lines soon, despite the fact that you have a team. This is because we are outnumbered against Iwa and Kumo."
He stopped for a bit, seeming hesitant for some reason. He grabbed something from inside his desk that looked like a diary of some sorts,and handed it to him.
"Jiraya has been nagging for a while now, and I have come to support his decision: this is everything that I have about lord second's not-so-famous-but-incredibly-powerful teleportation jutsu."
Minato's eyes widened in shock. He had talked to Jiraya about space-time fuinjutsu and learned the existence of such a jutsu made by the second, but never did he expect to actually get something from it!
"This is A-rank easily. This notebook has been sealed by me and Danzo, such a book must not reach enemy hands at all costs: you will channel your and only your chakra in this seal once an hour: failure to do so will destroy it. You will give it back before every mission you take outside konoha, and you will never, ever talk about it to anyone, yes, even Jiraya. Am I clear?"
"Crystal" Minato replied seriously.
"Good" the hokage said, and smiled. "Enjoy."
--
So warped about the diary, Minato almost forgot about his new team.
Thankfully he had a few minutes before he was expected to show up, and he was fast, even without a space-time jutsu.
He ran down the corridors of the academy that he had once attended, and quickly made it to the class. Opening the door he was greeted to basically 30 something stares all looking at him. Thankfully the academy teacher came to his rescue and called out team 7.
3 kids stood and walked up to him, 2 with stars in their eyes that oddly reminded him of Kushina plus ramen, and one with total indifference.
He smiled at them, waved at the instructor, and walked to the nearest training ground, his 3 new students following him.
--
Walking to the training grounds had been a huge task: he was going to the closest one when he remembered that he had a team now,and couldn't go anywhere he liked.
Training grounds had rules to follow, sparse rules, but rules non less: 1) only genin or over could enter 2) teams had specific training grounds based on numbers (team 1 had training ground 1, team 2 had training ground 2...) and 3) training grounds where for practicing only. Any new high-destruction jutsu are for waste lands and territories not owned by konoha. (he, for example, had gone to one of the waste lands earlier to master the rasengan)
Thankfully for him, his genin didn't (or pretended not to) notice his sudden change of direction, so everything was fine. The after effects of the chakra pill were being felt though. He decided to not do anything too chakra intensive.
"Hi, my name is Minato Namikaze, just call me sensei, pleased to meet you." He said, and made a motion for his students to continue.
"I'm Obito!" Said with a grin the easily most excited person here.
"Hello, my name is Rin" said the only girl on his team with a smile.
"Kakashi" said the final member simply.
Minato nodded with a smile, internally grimacing: now what?
"Right! I bet you're all very tired, so why don't we all go home and meet here tomorrow morning at 7-"
"We have done nothing all day" said Kakashi plainly.
Shit. "That's great!" He said with enthusiasm "that means we can get to know each other straight away!" He blinked, pretending to have just now remembered something "therearenomissionsnow, weshouldjuststarttommorow, beherebyseven,anddon'tforgettoeatbreakfastby" he said quickly and suishined out of the area before Kakashi could say anything else to stop him.
--
He just wanted to sleep.
Walking to the memorial stone, not too far away from earlier, Minato tiredly sat down right in front of a very specific hole and buried a simple shuriken.
The idea was to remember a very specific day and a very specific time, and travel to it once he was like 70 or something, and tell his past self everything that had happened in life, jutsu included.
If it worked it would be the biggest cheat he had ever done, even by his standards of cheating (the guy who copied a jutsu from a tailed beast, has seals against genjutsu, is basically too fast for taijutsu and kenjutsu, knows senjutsu, and will probably have a space-time jutsu in his arsenal soon.) and if it doesn't work, no harm done. It's a win-win situation with no problems if he doesn't succeed, so Minato saw no harm in trying.
Today the hokage gave him the jutsu that can give space-time the middle finger, if this wasn't a day to remember, he didn't know when would be.
4:58
It would be soon now.
4:59
Just a bit longer...
5:00
5:01
Minato shrugged and got up, OK, so nothing happened, big deal, he still had a space-time jutsu to learn-
"HOLY SHIT IT WORKED"
Minato looked up from the hole he was in and saw 2 konoha ninja (or at least they seemed so) come from no where, all of them staring at him with grins.
Was this a coincidence?
"Hello-" he started only to be cut off by one of the strangers.
"No time to explain dad, we are just shadow clones: just stay still-"
And then Minato's world went black.
Catching him before he fell, Naruto quickly caught his father and looked at Ino. The most important part of this mission was on her shoulders.
She nodded and got to work. Going through a huge amount of hand seals, she placed a hand on the not-yet-4th-hokage and did her job.
Seeing this, Naruto placed a hand on her shoulder and channeled chakra.
With a whole more chakra to work with, Ino easily managed to get most of the work done.
Noting that he had almost finished his chakra, Naruto quickly placed a few seals on his dads stomach, sealing a temporary imprint to explain the situation, and disappeared, his charka being finished.
Naruto Uzumaki no longer existed.
Ino grimaced, she didn't have enough chakra to finish the jutsu, she'd have to improvise-
Ino Yamanaka no longer existed.
Unknown to the entire world, history had changed.
