Chapter Text
Sasuke and Naruto where in a fight for their lives, the two strongest ninja in the world had their backs against the wall struggling to keep up with a new threat. It wasn’t like that at first, of course, but the longer they fought the less strength and chakra they had. This guy had more stamina and chakra reserves than Naruto himself and that was saying something.
“We have to make a retreat…” Sasuke reluctantly said through heaved breaths.
“What?! No way teme!” Naruto shouted back his fist held tight.
“What other options do we have?!” The Uchiha nearly broke. “Naruto we either stay here and die or retreat and make a new plan to take this guy down! Something that will actually work…”
The blond actually flinched, but in the end he nodded.
“But how…? If we move now we’re sure to be spotted…”
Before Naruto could get in another word Sasuke moved his fallen bangs out of his face, his rinnegan swirled with the sharingan tomoe. He was going to rip open a portal and get home that way, but the Uchiha barely had enough chakra to conger half a clone. Naruto wanted nothing more but to stop him but what other options did they have? He could see Sasuke tense up and grit his teeth as he managed to open a portal.
As they stood Sasuke had Naruto go through first, but before he could go himself a powerful jutsu hit him and flung him into the portal but this jutsu also knicked the portal itself. It changed slightly before closing in on itself.
Naruto glanced back only to see an unconscious Uchiha flying at him. Panicking the Uzumaki managed to grab him and held him tight, afraid they would get separated. A few seconds later they reached the opening and fell out, landing harshly onto the ground.
“Hang in there!” Naruto yelled managing to sit up careful to handle Sasuke.
“Um…” An all to familiar voice got the blondes attention.
“Sorry but…” Naruto’s eyes widened as eyes landed on none other than Kakashi, but something seemed off. “We just got off a mission and would rather not get into a fight. So I hope you’re more or less a friend.”
Worried glances made Naruto aware of three other people, blinking he thought he might have been going crazy. There stood a younger version of himself, Sasuke and Sakura.
“We-“ He wasn’t sure what to say. Was this a genjutsu or were they truly flung into the past? It wasn’t like he could disguise himself now and it seemed Kakashi noticed the similarities of himself and his younger self. “We’re from the future, we can explain more later but right now I need to get him to a hospital!”
Kakashi looked a little flabbergasted, he knew something weird was up with the two but never would have guessed. Of course he was still sceptical, but that portal had enormous but familiar chakra had him split. But seeing the others critical condition he didn’t hesitate to agree and ordered the other three to go on ahead as he helped them.
“Come on, the village isn’t too far from here.” Kakashi was about to help Naruto with Sasuke sense even the blond looked beat up.
To his surprise however Naruto picked the other up with ease blinking off his shock he lead them back to the village and quickly to the hospital. Quickly explaining that they were allies and one of them were badly injured and needed treatment ASAP. Trusting Kakashi they took him to the emergency room, and once they disappeared the Jonin’s visible eye locked on to Naruto’s waiting for an explanation.
“I would feel better if we were in a more secure area…” Naruto said glancing back at him. “Or at least one with less people.”
Kakashi couldn’t argue, there was something this guy didn’t want others to hear. He knew the hospital well enough where there was a nearly abandoned area they could go to and motions him to follow him.
“Sasuke and I were fighting a really powerful enemy, we were being pushed into a corner and forced to make a hasty retreat. We couldn’t really run without being attacked so Sasuke forced himself and opened a portal to get us home...he forced me to go in before him and I think something happened because he was flying at me unconscious. And when we came out the other side...we’ll you know the rest.” He explained.
Kakashi looked speechless. “I have to say, that’s a bit unbelievable...but both of your chakras feel very similar albeit stronger ten fold. So for now I’m choosing to believe you, and until he wakes up we won’t have the full scope of the story…for now we’re going to have to keep this on the down low.”
Naruto gave him a nod, though he knew Kakashi had a ton of other questions but the blond was more worried over Sasuke than anything. They returned to the main part of the hospital just in time to be greeted by a medical ninja.
“Your companion will be alright.” He addressed the blond. “Though I’m surprised he’s not in worse condition considering the hit he must have taken.”
Naruto looked really relieved. “Is he awake?”
The medical ninja shook his head. “No but we did move him so if you want to be with him, he'll be in the last room down the hall to the left.”
The blond didn’t hesitate and rushed to his room, Kakashi in toe. It had been a while sense Sasuke was in a hospital, so seeing him lying there looking very vulnerable was a bit sickening. He had to calm himself he couldn’t get upset now.
“Can I ask how he could have opened a portal? Is it a new jutsu he worked on?” Kakashi questioned, it was one of the many inquiries he had and this one seed to couldn’t wait.
The Uzumaki shook his head. “No actually, a lot happened...Sasuke gained the rinnegan it his left eye”
Kakashi became quiet, he was taken aback he was aware of the stories but to have a student gain a powerful dōjutsu like that was shocking.
“I should warn you…I mean you are my sensei after all. There’s a bigger threat than you could have ever imagined...even if it changes our future I’m actually willing to risk that...I need to tell you.”
The two glanced at each other, Naruto more serious than ever. Kakashi decided this was worth the time and sat down to take in Naruto’s tale.
