From WellJusticKLove (AO3) "you have stated, Naruto will change the past, right ? (To save Kakashi) maybe he can save Rin (or nit letting Kakaashi kill her himself ?)"

Standing and stretching, Naruto looked at his sleeping bride. The sun's rays shone on her face, sleeping and at peace, her beautiful face framed by soft black waves. Smiling, he went into the kitchen. Humming quietly, the blond looked out the window as his mind drifted back to the day before. So many of their friends were there to support them in their union. Tsunade, Iruka, and…of course, Kakashi was there. Leaning forward, putting his chin on his hand, Naruto smiled. Kakashi looked simply…stunning in his clothing. That suit looked fabulous on him. Naruto's lips turned down in a frown. He should not be thinking like that. Naruto was married and Kakashi never looked at him like that anyways. That's why Naruto married Hinata.

Oh, he loved Hinata, very much…it's just…well, his first choice would have been Kakashi. However, Kakashi was attracted to no one, and definitely not Naruto. Hinata wanted to marry Naruto, was sweet and devoted, a great friend, and would do well as a life partner. Naruto wasn't an idiot…he didn't want to be alone his entire life. So…he settled on Hinata. It's what everyone expected, anyways. It was nice and comfortable. She would be a good life mate and a good Hokage's wife.

The knock woke him from his reverie. Going over to the door, Naruto opened it. A box was on the floor, wrapped in orange paper with a black ribbon. Stooping, he picked it up…it was heavier than it looked. Smiling at the coloring, he read the tag. "For Your Wedding." Sitting it on the table, he decided to wait until Hinata woke up. Going to get his tea, he blew on it, cooling it. Propping himself up on the windowsill, he looked out the window, his eyes drifting to the Hokage Tower. He thought he saw movement in the tower, but he was sure it wasn't Kakashi. It was much too early for him. Naruto's mouth lifted up in a smile. Suddenly, he felt Hinata's arms wrap around him as she rested her head on his shoulder. "Good morning." she whispered.

"Hey, morning." Smiling he pulled her into a kiss. Pulling away and twisting around, he motioned to the box. "We got another present. You wanna open it?"

Hinata shook her head no. "Those are your colors; I'll let you do the honors." Grinning, Naruto started undoing the ribbon. Opening the box there was a huge stench; Naruto almost vomited. Looking into the box, the world became slippery and it was hard to breathe. There was Kakashi's head, sightless eyes staring at his former student.

"We can't just stand here and do nothing!" Naruto's fists were at his side; he was shaking in anger, his face red. Hinata stood behind him, one hand on his shoulder to provide him support.

Tsunade sat at the Hokage's desk, reluctantly having been brought back as Hokage at the Sixth's demise. She still had the hangover from the wedding reception the night before. Shizune stood at her side, large dark eyes solemn. "I am not doing nothing, Naruto. However, I cannot run off half-cocked to find Kakashi's murderer. The village has been locked down and I have already sent out several ANBU to find any leads." Her hazel eyes shone with sadness and fatigue. "His body is being analyzed."

"I'm going! Kurama and I can find them!" Naruto's rage boiled over, tears pricking the corner of his eyes as the beast coiled in agitation inside him. Kakashi was Naruto's precious person…therefore making him Kurama's precious person to an extent, since Naruto was going apeshit nuts without the silver-haired sensei.

"You will do no such thing!" Tsunade snapped standing and slamming her hand on the desk, the wood groaning in protest. "I do not need you sacrificed as well because you run off all hotheaded! It may very well be exactly what the murderer wants!" Her hazel eyes glinted in warning.

"Naruto, Tsunade is right." Guy responded. His voice sounded dead. Naruto swung his head angrily to tell Guy his what fors, but stopped at the sight. Guy's brilliant smile was gone, his eyes dull, his body stooped. Rock Lee was staring at his former sensei in worry. "This is an attempt to get you off guard and not thinking straight. We do not know what they want, but it is likely you and the fox are a part of the plan. Kakashi would never…" Guy stopped as his voice broke and he looked away.

As voices kept speaking around him, Naruto felt suffocated. He heard various phrases, vaguely deciphering that the village was in complete lockdown and ANBU were being assigned to him and Hinata. Shaking his head, he shrugged off Hinata's hand and stormed out, hearing Tsunade's voice following him, "You aren't to leave the village, Uzumaki."

Naruto walked through the village, sightless, looking for somewhere to be alone. Hinata followed him for a bit. Finally, he stopped. "Hinata, just…go home. I need some time alone." He tried hard to not make his voice sound angry. Squeaking her approval, Hinata gave him a hug. Naruto returned it, kissing her temple before she scampered off. Walking aimlessly, he found himself outside of Hatake's apartment. Sliding down the wall, Naruto buried his head in his hands, and wept…truly wept for the first time since this morning when he found Kakashi's head.

An overwhelming feeling of emptiness descended on Naruto. He had never imagined life without Kakashi…never thought he would need to. Kakashi was always so…dependable. He was one of the first to be somewhat kind to Naruto, after Iruka, of course. And…he was a prodigy for Kami's sake…he should have been smart enough to keep himself from being killed, damnit!

"He wouldn't want you to sacrifice yourself. He would want you to live life, full of the springtime of youth." Guy's dull voice wafted over Naruto. Looking up, he saw Guy's sad eyes. Saying nothing, Naruto put his head on his bent knees, wrapping his arms around his legs. Guy sat down next to Naruto, patting the young man's shoulder.

"He loved you but feared saying anything because you seemed so happy with Hinata." Squeezing his hands against his knees, Naruto wished Guy would shut up. He didn't need to know this. It would not fix anything. It just ripped open the wound in his heart, making him kick himself with how stupid he had been for not making a move of his own. Fresh tears leaked out, as he said nothing, silently sobbing.

Naruto, I am sorry. Would you change anything if you could? Kurama's voice curled through Naruto's brain.

You aren't funny. You know I would. Esp…especially now, after Guy.

But would you give up everything? Would you give up an eternity for him, even if you were never able to be with him? Naruto could feel Kurama's curiosity.

You know I would, but I can't, so this is stupid daydreaming! Naruto bit back angrily.

Not necessarily. We can go back in time, you can change one thing, and then we can be thrown back here, to this time in the present. But then…you must live with those changes, good or bad. And…there is no guarantee that Hatake will not be killed.

However…there is a chance I can save him, right? Naruto's heart lifted at the possibility of having Kakashi alive.

Yes, that is always a possibility. But, there is a cost.

A cost? Whatever the cost, I'll pay it.

Don't you want to know the cost?

No, it doesn't matter, let's go.

Well, where do you want to go to change things?

Um…I…I dunno…wait…Kakashi's head was given to me as a wedding present. Maybe this is about Kakashi? Scrunching his nose up, Naruto thought and thought and thought. What led Kakashi to where he was? Kakashi developed quite a reputation, and that was due to his past. What drove Kakashi to become so ruthless in his younger days…was it his father? Shaking his head no, Naruto felt like that was not the answer. Or at least not the whole answer. Thinking longer, he suddenly knew. He remembered Kakashi telling him one night about Obito and Rin. Naruto was shocked and saddened by the story. He had wanted nothing more than to take that burden from Kakashi, but Kakashi would not give up that burden. Kakashi felt it was his to bear. Nodding in resolution, Naruto knew it was with Obito dying and then Kakashi failing to save Rin. He blamed himself, even though Rin threw herself on his Chidori. I want to go back to before Rin was killed…I know! I can stop Kakashi from killing her…somehow. How long will I have to make those changes?

I can keep you there for about ten minutes.

Right, let's do it!

Sitting up, Naruto took a couple calm breaths, resting his hands on his knees. He wasn't sure what would happen, but he didn't think it would feel real good. Suddenly, it felt like electricity was jolting through his body and he was falling. As his head hit the ground, he let out an oof and looked up at…the sky? Shaking his head, standing up, he shook the dust off his jumpsuit as he tried to get oriented and take in his surroundings. Suddenly, he remembered the conversation with Kurama. Looking around, he saw he was on rocky ground. Not sure exactly what he would need to do, he sat down and started trying to achieve sage mode. Suddenly, he heard running. Feeling the completion of the sage mode, he went and hid.

He saw Kakashi…a much younger Kakashi…and a brunette girl with Inuzuka type markings of purple on her face running. Puffing, panting, the two came to a stop. Naruto's eyes widened. "Isobu?" he gasped as he felt the three tails inside the girl. Stepping out from his hiding space, Naruto called out. "Kakashi?" Jerking his silver head to the side, Kakashi eyed Naruto. Spying the Leaf headband, he relaxed a little, still on edge. Tilting his head to the side, Kakashi warily eyed the blond who looked very familiar.

The brunette looked to Naruto as well, frowning and backing up slightly. Naruto held his hands out in a gesture of supplication. "Wait! I'm not a threat. Let me help…I can help get Isobu out without you dying."

Kakashi jerked his head to Rin. "Death is not an option."

Rin's eyes frantically scanned Kakashi before looking at Naruto. "How?"

Naruto came up gently. "I don't have much time. I have the ni…one of the nine tails in me as well. I know a technique that will get the three tails out of you, helping you survive." Rin looked disbelievingly at Naruto as he rushed on, "You have to trust me…if you were wanting Kakashi to kill you, then it won't hurt to have me try, right? Maybe you can survive." He tried to give a disarming smile.

Suddenly, they heard feet…lots of them. "Kakashi…" Naruto started, but Kakashi nodded, moving his hitai-ate, exposing the red and black eye as he turned his back on the two, preparing to fight.

"H…how do I know this will work?" Rin asked, confused.

"Look, I don't have much time. Trust me." Naruto started making the appropriate hand signs. Help me with this Kurama.

What are you planning to do, kit?

We are going to unseal Isobu.

Right.

As Naruto infused chakra into his hand signs, he looked at the girl. "You are Nohara, Rin, right?" As she nodded, he continued. "Where did they seal the beast inside you?"

Speechless, her mouth agape, her hands went and moved her clothing, exposing the seal to Naruto's eyes.

"I don't have time to explain. Here." Placing his hands on the seal, he cast the jutsu. As Isobu…well…climbed out of Rin, Naruto completed the jutsu. Looking at Naruto, Isobu looked confused. However, Naruto could tell that Kurama was talking to Isobu, and at that Naruto gave out the tiniest bit of a sigh. Confirming that Isobu was gone from inside Rin, Naruto smiled and then turned to leave. Seeing Kakashi holding his own against the Mist ninja, Naruto slipped into the forest, Rin calling after him. Stumbling into the forest, he felt that electricity again…

Jerking awake Naruto looked around. He was in the forest. Sitting up, he noticed that ANBU were getting up as well. A figure with a bear mask looked at Naruto. "Frog, time to go." Confused, Naruto looked down; he was wearing ANBU gear and had a mask that looked like a frog hanging from his belt. Quickly composing himself he nodded and got up, confused but trying to act normal. Following the group's lead, he slipped on the mask and looked at the other members. He couldn't really tell who anyone was. Traveling through the forest, Naruto wondered what his new life was going to look like. Suddenly, he recognized the Leaf Village. Good to be home Kurama…huh?

We will see what kind of home it is.

Nodding, Naruto said nothing, just following the troop to the Hokage Tower. Walking in, his breath caught. There was Kakashi! Alive and well! Two onyx eyes that were very alive and well. Letting out a breath he didn't know he was holding, Naruto smiled. After the debriefing, he turned to leave. "Frog, a word?" Kakashi's silken voice caused Naruto to catch his breath in his throat.

Stopping, Naruto turned around. Bowing on one knee, Naruto waited.

"Naruto, do not bow to me." Standing, Naruto removed his mask. He smiled at Kakashi. He was so happy the man was alive!

"Yes, Lord Hokage?" Naruto asked, checking to see if the reaction was the sa…

"Naruto, please stop with the Lord business." Kakashi sighed wearily.

Chuckling, Naruto nodded. "Yes Kakashi-sensei. What do you need?"

Smiling, Kakashi came around the desk and leaned back, crossing his arms as he smiled through his mask. "Since you're back, are you coming over for our weekly dinner?"

Smiling genuinely, Naruto nodded his head enthusiastically.

"Wonderful! Rin is making homemade ramen, just like she promised." It was at that moment that Naruto saw the wedding band on Kakashi's hand.
