A/N: My brain is so weird! I've been reading a bunch of time travel fics, and this popped into my head. Anyway, I know there's no Konoha Oinin, they're unique to Kiri, but everyone else does it...
Also, since the leader of a village that's not one of the Big Five isn't a Kage, what are they? Anything in specific?
A certain boy known as Uzumaki or Namikaze Naruto was rather annoyed. In his time in the Hunter-nin, the seventeen-year-old blonde was not liking how many times missing-nin broke his mask or managed to hit him with a jutsu that killed anyone without Kyuubi-healing. Like that super-massive lightning sphere, or those laser bolts, or the fire that was covering every inch of his body. So he was working on a new space-time ninjutsu that would allow him to rewind time several seconds and then prevent whatever was going to kill him- well, kill anyone that wasn't him. So, armed with this new ninjutsu with a dash of fuuinjutsu for good luck and some body-anchoring, he strolled confidently into the Oinin office for his newest mission, safe in his disguise as Fox.
"Fox," stated the Oinin commander, "Your mission is to eliminate the A-ranked missing-nin Gakura Irotsuchi, formerly a Jounin of Takigakure. Here is the necessary files, and this is an A-ranked mission. Departure is at eight hundred hours. Dismissed." Naruto took the packet, grinning under his ceramic kitsune mask as he Konoha-Shunshin'ed to his small apartment. Finally, a chance to try out his new Jikūkan (Space-Time) Ninjutsu! He packed quickly, and after eating some beef ramen went to bed, eager for his mission the next day.
Before the mission began, anyone could see a certain blonde staring sadly at the memorial stone, his whole demeanor different. Gone was the widely smiling mask, the hyperactive blonde known as Konoha's number one hyperactive unpredictable knucklehead ninja. In his place stood a sad man, one who had seen war, with all of its horror and all of its glory. But there was a certain name on the stone which every day he leaned down and traced with his fingers. He couldn't save her.
Why? Why did that ever have to happen? Why did there have to be an attack by A-Rank missing-nin on their vacation together? It had taken four to strike her down while another pair engaged Naruto. That day, his world had been shattered, and he had gone straight to three tails and ripped apart the missing-nin, A-Rank or no A-Rank. Then he had fallen to his knees at her side and cried. Uzumaki-Namikaze Naruto cried. It had been three days before he had returned to Konoha, carrying her bridal style, covered in blood and tears. Why couldn't he have moved faster? Why couldn't he have gone to her, screw the distracting pair? Why?
As he was lost in thought, the time of the mission rolled around and a small alarm beeped. He stood up, head bowed, and proceeded on the mission, jumping through the tree boughs, thankful that his tear lines were hidden under his mask. It took only several hours to reach the appointed area. He staked out the small camp, blending into the tree bark easily as he waited for his mark to put in an appearance. Patience was a great virtue among hunter-nin.
It only took several hours for the man to put in an appearance. Naruto attacked with shuriken from the cover of the branches, and the man blocked them with a kunai. They quickly engaged in a taijutsu/kenjutsu battle, the fugitive's katana versus Naruto's twin kodachi. It was not long before the Kyuubi Jinchuuriki began to gain the upper hand and Irotsuchi resorted to ninjutsu.
"Suiton: Mizurappa! (Water Release: Water Trumpet!)" the man blew a powerful jet of compressed water at the blonde, who used Kawarimi no Jutsu to come behind him and call "Fuuton: Daitoppa!" blowing the man through a tree or two. He came back out, calling "Suiton: Suiryuudan no Jutsu!" pulling water from a nearby lake into a massive water dragon with golden eyes that smacked into Naruto's face, cracking his mask.
Goddammit!
Naruto began a series of seals for his Jikukan technique, wary and prepared for an attack. So when the other man finished his first and called an unknown technique, that being "Ninpou: Ōbārōdo no Kiri!" and blowing a pale mist out over Naruto. Figuring it to be a precursor to increase another jutsu, Naruto didn't interrupt his seals and when he called out, "Jikanton: Makimodoshi!" all he remembered was a flash of white light and then blackness. Silly Naruto, ignoring the mist, which caused people in the mist to use much of their reserves in their next technique so that they collapsed from premature chakra exhaustion. But with Naruto's reserves, he overloaded his time-travel jutsu and he simply disappeared.
"Sensei, there's a guy over here! I think he's dead!"
"Tch. He's only unconscious, knucklehead. Sensei, we should take him to the hospital. He wears a Konoha hitai-ate."
"Will do, guys."
And they disappeared in a yellow flash, an unconscious hunter-nin in a cracked mask over the teacher's shoulder.
