Disclaimer: Naruto x Rosario Vampire - I own neither
While I was taking a short vacation from fanfiction to celebrate my birthday, this idea struck me.
Story Start!

"Woah!"

"I know, I just found it... it's super weird isn't it?" Uzumaki Naruto asked as he pointed to a shifting air in front of him.

Naruto was a young boy, a mere 12 years old, who was currently on a training journey to get stronger before returning home. As of yet though, his master had only been working to get his Taijutsu skills and his other basic skills to the level of a Jonin, or at the very least on par with Chunin. All of the techniques in the world would mean nothing if he didn't have the basics needed to use them properly.

Still, it was boring.

This was exciting though.

They were in the Land of Fire, yet in front of them at the moment was a shimmering, almost ice-like thing in the air that seemed to not even be there at all. It was like ice-like mist that floated in the air, right near where they had made camp. Naruto had gone to take a leak, and he noticed a shimmering in the air in front of him.

So he peed on it.

He peed on the simmering thing in the air, and when his piss touched the air that was shimmering, it vanished.

"Hmmmm?" Jiraiya, a legendary ninja and his master, was crouched down as he looked at the shimmering in the air. The two of them were both currently relaxed, since they had made camp and were waiting for their dinner to finish cooking. A rough day of taijutsu training and followed by waterfall meditation had gotten them both very hungry, but hunger could be put to the side for the moment.

This was very interesting.

"Look, watch this." Naruto picked up a stick off the ground and poked the air with it.

The stick disappeared where it touched the air, but it wasn't erased, instead, Naruto was able to pull the stick back out and make it reappear.

"Some sort of Space Time Ninjutsu, or a Fuinjutsu... no... I don't feel any chakra." Jiraiya muttered to himself with intrigue. He took the stick Naruto was holding, and he touched the end of it with his finger, only the end of it that had gone through the shimmering air. He didn't see anything, but it was the dead of night, and there was no moon visible. It was a New Moon at the moment, and if there were any changes to the stick, it was so small that he couldn't notice it.

Well, there was one change.

The stick was colder than before, a little.

"Hah!" Naruto shoved his arm through the shimmering air. "COLD!" Naruto yanked his arm right back out with a handful of snow in his fist. Naruto tossed the snow to the ground, shaking his hand.

"Didn't hesitate... but... that is interesting." Jiraiya stuck his own arm through the shimmering, and he felt his hand make contact with snow on the other side of the air. His hand vanished, as if there was something invisible like a barrier. Naruto shoving his hand through it like an idiot clued him in to the fact that it wasn't a dangerous kind of barrier. The barrier extended no more than 3 feet across, and 4 feet tall.

He pulled out a handful of snow, and looked at the snow.

He wasn't in some kind of Genjutsu, he had already tried to break one the second his hand went through the air. Yet, in the Land of Fire, in the middle of Summer, there was indeed snow right in the palm of his hand.

"Cool, right?"

"It is, it really is... it isn't Fuinjutsu, and it isn't Ninjutsu either... This snow is yellow."

"Well, I DID pee through the mystery air thingie earlier." Naruto scratched his cheek, and Jiraiya recoiled in disgust, throwing the snow far away from him. Naruto was laughing at the reaction, before he pouted when Jiraiya struck him right on top of his head. Jiraiya, after striking Naruto, wiped his hand on his pants and looked at the barrier.

He pulled out a scroll.

He unfolded it, and it there was Fuinjutsu patterns all over the scroll.

"Hah!" Jiraiya stated... only for nothing to happen. If the barrier had been some kind of ninjutsu, his scroll would have absorbed it right then. He rolled his scroll back up. He had already ruled out ninjutsu, but having confirmation was nice as well. He rubbed his chin in thought, and looked at the shimmering air more. '... Looking at where the moon should be, I'm guessing it's about... 11:30 PM... so... this wasn't here earlier, we did pass by this spot on the way to set up camp.' Jiraiya hadn't seen shimmering air.

Naruto crouched down and copied Jiraiya's position, rubbing his chin in thought as well.

"So..."

"It might be a different time space completely..."

"What?"

"Space and Time Ninjutsu and Fuinjutsu have... what am I explaining this to you for, you're too stupid to understand it..." Jiraiya was about to go into a massive and detailed explanation, but after considering who he was talking to, he figured that it was a wasted explanation. Jiraiya, instead, crouched down enough so that he was small enough to squeeze through the shimmering air.

The second he went through it, he saw snow.

A land of snow and ice, with a night's sky that had a Full Moon instead of the New Moon that was on the other side. It was cold, but he didn't plan to be on this side of the barrier for long. He backed out of the barrier.

"Woah, you vanished!"

"Okay Naruto... I'm going to go through the barrier, and I need you to count to... 100." Jiraiya stated after coming back through the barrier.

"Why?"

"Because I said so." Jiraiya stated as he went back through the barrier, and he entered the land of ice and snow once more. When Jiraiya was inside of the barrier, he stood up straight and started to count. "1... 2... 3..." Jiraiya counted at a steady pace. Well, he counted at the pace that Naruto would count at. It wasn't the most accurate way to count, but it would give him a small idea of what he was dealing with.

For starters, the fact that in the night's sky there was a full moon instead of a new moon was different, not concerning, but different.

He kept counting while thinking.

Time flowed differently on this side of the barrier, but time flowing differently wouldn't make the moon different the way it was, and there were no trees nearby that looked like the trees where they just came from. So it wasn't a barrier that changed the flow of time, instead, if he were to guess, he was in a different dimension completely.

'An overlapping dimension... this dimension and the dimension Naruto and I came from, there must be some kind of barrier where the dimensions overlap. In the distance, I can see light... looks like a city maybe... so this is a civilized dimension.' Jiraiya could see in the FAR off distance that there were lights, meaning running electricity, or at least this dimension's version of it. He rubbed his chin in thought as he looked up at the moon again. 'That way... that way seems to be... north... so the time here is maybe... 3:45 AM... it's a guess though.' Jiraiya judged as he guessed which way seemed to be north and used that.

Overlapping dimensions didn't happen often.

Even when they did, just because the dimensions overlapped didn't mean that you could walk through them like he just did. That meant there was some kind of time and space barrier around this area. He would guess that the presence of a barrier in this spot was what made the overlapping dimensions capable of being walked through, because the barrier was creating a small hole through space and time where the overlap happened.

Jiraiya finished counting and went back through the barrier.

"17... 18..."

"Brat, did you start counting the second I walked through the barrier?" Jiraiya asked when he heard Naruto reach 17 the moment he came back through the barrier.

Naruto gawked at him.

"Duh, you think I can't count?" Naruto deadpanned. He wasn't the smartest, but he was able to do basic math just like anyone else. He raised an eyebrow though when Jiraiya looked at the shimmering air again. Naruto looked at the barrier as well, though he didn't know why Jiraiya was looking the way he was.

Jiraiya rubbed his chin.

'... It isn't exact, but time flows about... 1 to 5... so one second here seems to be about 5 seconds there... That explains why the moon is full over there, but is a new moon over here. The flow of time between that dimension and this dimension isn't 1 to 1.' Jiraiya was learning quite a bit just by seeing the moon cycle differences, and knowing that time flowed differently.

He and Naruto had been training for about 4 months out of the 2 and a half years they had to train, and while Naruto had made great progress, the fact was that the Akatsuki were all above your average Kage in power. Naruto, unless he mastered the Kyuubi, or learned Sage Mode, or even started to use Shadow Clones to train, wouldn't be a match for the Akatsuki.

There was problems though.

Naruto was not mature enough to learn Sage Mode, which was an extremely dangerous form of training that could kill him easily. He didn't want Naruto to learn Sage Mode until he reached a higher level of maturity and patience. So that form of training was out, even if he knew that Naruto had the potential to be a great Senjutsu user.

Shadow Clone training was out as well.

While the boost to power would be great, Naruto wasn't mature enough and didn't have a good grasp of the basics. He knew that if he introduced this training to Naruto, then Naruto would abuse the training and grow too strong too quickly. He had faith in Naruto, but he knew reaching extreme levels of power too quickly, without the maturity to wield that power, Naruto could easily become corrupted by the power.

Which is why he wanted to use this training journey to increase Naruto's basic technical abilities, and then learn how to use the Kyuubi.

'Still... 2 years to master the Kyuubi's power... that isn't a lot of time. But... 10 years on the other hand... no, no... it's too risky... but...' Jiraiya felt a great temptation within him. It would give Naruto about 8 extra years of training. Not only was an extra 8 years enough time to master the Kyuubi, but it could also give Naruto time to mature enough to learn how to use Sage Mode as well, and with that maturity, learning how to train with Shadow Clones would be something he could teach Naruto.

The fact was that this was an amazing chance, but a risky one as well.

2 years here was 10 years there, and 8 years was a long time for a Jinchuriki to gain strength, and he was sure that Naruto would be easy to convince. There were risks through, but did the benefits outweight the risks?

"... Naruto, what if I said we could get 10 years of training instead of 2 years, and get back to Konoha in time for you to save Sasuke?" Jiraiya asked Naruto. He saw Naruto was grinning, and in that moment he knew that Naruto was down for the idea. Still, he knew Naruto was happy to do it, but that didnt' mean it.

He was so tempted.

The risks seemed less and less the more he thought about it, and the benefits were almost too much for him to ignore.

He pushed Naruto through the barrier, before he crouched and went back through it himself. Naruto was face first in the snow.

"COLD!"

"Yeah... time flows different here. By the time you counted to 17, I counted to 100, meaning that if we train over here, we can train for about 10 years instead of the 2 we have left to train." Jiraiya explained to Naruto. It was cold, but they would go get there stuff and make for the city in the distance.

"Awesome!"

"Right, we should get out stuff, and come back when it's daytime here." Jiraiya stuck his arm through the portal first.

The air shimmered.

The portal closed, and Jiraiya's eyes widened when his arm was cut off at the bicep. It was a clean cut, right through the muscle and bone. Jiraiya shouted in surprise pain for a moment, but quickly grabbed Naruto's jacket, tore it off of him, and tied it to his arm to stop the bleeding.

'Shit...'

"Pervy Sage, what happened?!" Naruto rushed to Jiraiya's side and helped him tie off his bleeding arm even tighter. "The shimmering is gone!" Naruto stated as he looked at where Jiraiya's arm vanished off to.

'The dimensions, they must not always be overlapping... damnit. When I was thinking of the risks, I didn't think that the dimensions would stop overlapping, and the way back would get cut off like this... damn...' Jiraiya should have known. The shimmering air had not been there when they stopped to make camp, meaning that it had appeared, and if it appeared, that meant it could disappear as well.

They were stuck for now.

He forced a smile.

"Yeah, I closed the barrier for now, wouldn't do to be followed through... guess I wasn't fast enough to stop the barrier from taking my arm though." Jiraiya lied through grit teeth. He hated to do it, but right now was not the time for Naruto to think they would be stuck in this world. It would ruin his training, and just like there was a chance for it to close, there was also a chance for the barrier portal to open back up again. "Lets go... that way, get my arm treated." Jiraiya pointed to the city in the distance.

Luck hated them though.

A blizzard started to pick up at that moment.

They had to hurry as fast as they could.
