Disclaimer: Naruto is not mine. I own nothing except some OCs. I made no money off this story.

Warning: the main pairings here will be HashiMada TobiIzu and SasuNaru. OOC. Mentioned about Political marriages. Unbetaed chap 1-4. Gramatical Error Slow paced(?) update. Eventual MPREG.

Note:

1. TobiIzu here is a continuation from my other fanfic which is called "Tobirama and Izuna" about their childhood time. HashiMada's childhood like in the manga/anime I don't bother adding the romance from their past because I think it was crystal clear that Konoha's founder have 'something' going on between them.

2. I ignore the canon's epilog (of course coz SasuNaru is a pair, I don't want any woman between them) so the mugen tsukuyomi was cancelled automatically with Kaguya being sealed by Sasuke and Naruto. There will be no last fighting between Sasuke and Naruto like in the canon after Kaguya was sealed.

3. Sasuke's Rinnegan and Naruto's Rikudou Mode was temporary. His eyes back to normal eternal mangekyou sharingan, they lost those abilities after he and Naruto thrown back to the past.

4. I don't know the age of HashiMada and TobiIzu so I made it up. HashiMada 32, TobiIzu 29-30 y.o. HashiMada need to be at the same age because of the reincarnation transmigrant system like Sasuke and Naruto.

It works!

They sealed Kaguya when they touched her shoulders with the power given by Rikudou Sennin to sealed his mother. Team 7 felt relieved in a moment which turned into a horror as Kaguya attempted to use her jutsu Ame no Minaka to runaway from being sealed. Clearly, she has no enough chakra since hers was in process to be sealed. She absorbed chakra from Sasuke and Naruto which had their palms still on Kaguya shoulders. As Kaguya being covered by the moon stones, the sealing almost completed, Sasuke and Naruto's eyes widened. They felt their chakra drastically lost and being pulled by Kaguya's incompleted space-time ninjutsu in the same moment with Kaguya's sealing was completed.

On another hand, the mugen tsukuyomi was cancelled with Kaguya and Black Zetsu were sealed together. The people who was absorbed by the sacred tree was released. Kakashi and Sakura was shocked when Naruto and Sasuke's suddenly dissapeared into the air.

"Sasuke-kun! Naruto!" Sakura cried out loudly but neither was there to answer her.

In the battlefield where Uchiha Clan fighting with Senju Clan, the head of the clan of each was using their chakra generously. Madara Uchiha with his Susanoo and Hashirama Senju with his mokuton. As their chakra met, a sound of thunder and loud explosion blinding everyone near them. They were instinctively closed their eyes, halted their movements and only depending on their hearing sense. They heard something fallen hard in front of them. Anothers sounds were preseng, suspiciously like complaining about something.

"Oh, man! My butt is hurt! My head still spinning!" A teenager voice surprised everyone within hearing range. Cautiously, Madara opened his mangekyou sharingan eyes to see the figures say on the ground in front of Hashirama. A teenager with blond hair and black-orange outfit holding his head. He was wearing Uzumaki Clan symbol on his back. He conplained about his condition. Beside the blond teenager, sat another teenager with black spiky hair, lavender shirt and black pants. The boy in front of Madara, shaking his head and holding it with one hand, mumbling to the blond, "It means you are still alive. Stop complaining!"

Madara's eyes widened as he sees the Uchiha family symbol at the back of the dark haired teenager when he turn around to see his blond companion. He glancing at Hashirama which his expression give his confusion away. Who are they? These teenagers? They were appeared suddenly out of nowhere. An Uchiha and An Uzumaki without holding any weapon towards each other? The sight which never been seen at all in this age. What's happening here!? Their train of thought was halted when he sensed they their younger brothers before he was called.

"Brother!"

Izuna jumped to his side, at the same time Tobirama arrived at Hashirama's side too. Four of them had the same expressions when looking at the teenagers who was now stopped their discussion and stared at the four.

"Hn?" The blonde one looked between both Senju brothers and Uchiha brothers then grinned at the Senju brothers while waved his hand to them excitedly. "Grandpa Shodaime! Grandpa Nidaime! We're successed! She was sealed!" He was looking around, searching for someone, "Where is my Dad? Did you see him?"

Hashirama and Tobirama was... shocked beyond imagination as they were being called 'grandpa' by a teenager from Uzumaki Clan which was their distant relatives. "Shodaime and Nidaime... Do you mean us?" Hashirama asked in confusion, exchanging glance with Tobirama. At that question, the Uchiha teenagers beside the blonde one looking at them sharply. His onyx eyes widened and spread his sight around cautiously before his eyes glared at Madara and his younger brother who he recognized after Obito showed him Madara's memories. A realization hit him up. The Uchiha teenager hissed to his company, "Naruto."

The blonde teenager tilting his head, didn't understand, "Who else? Anyway, where is my Dad? And how come Madara still full of armor? The last time I saw him, he only wearing long black pants and who is the guy besides him? Obito doesn't have a long hair like that." He was mumbling.

"Naruto!" The black haired teenager grabbed Uzumaki's boy wrist with a warning tone. Naruto blinked at him, asked, "What is it, Sasuke?"

Sasuke looking at him seriously to warned him, "Don't talk to them."

"What? Why?"

"They are not Shodaime, Nidaime or even Madara who we are know."

Naruto frowned, "What do you mean?"

"If you look at their eyes, you'll see. Both are alive, not revived by edo tensei no jutsu," he whispered to Naruto who confirmed it immediately. He stood cautiously together with Sasuke still hold his wrist. They were looking around and realized they were in the battlefield. However, different with their war because... "So many Uchihas..." Naruto realized, the people around them who are still fighting and not because of the Mugen Tsukuyomi was cancelled. It was impossible because Sasuke was the remaining Uchiha clan member in their generation.

This is war.

But not Sasuke and Naruto's with Kaguya or black Zetsu.

Sasuke nodded. He noticed another thing which Naruto didn't paying attention. He activated his mangekyou sharingan eyes, "Not only that, Shodaime, Nidaime and Madara looks younger than we saw them at war."

Madara and Izuna shocked when they look at Sasuke's eyes. Four of them recognized it was not an basic sharingan pattern but the advanced one like Madara's and Izuna's. The Uchiha brothers knew the price for their eyes, to saw it on a teenager like Sasuke was very unsettled. It was not a common ability that a teenager could have.

Naruto looking closely and, "True! What's this mean?" He turned to Sasuke, "Your rinnegan is gone too! What's happening?"

"That's what we want to know," Madara talked for the first time. "Both of you just appeared out of nowhere in the middle of war. An Uchiha and An Uzumaki, although it was questionable because Uzumaki Clan usually have red hair."

"Well, it was from my Dad but my Mom has red hair."

"Who are you, then? Why are you with an Uchiha?" Asked Izuna who looked at Sasuke, "Is he your prisoner?"

"I'm—ummph!"

Sasuke put his palm covering Naruto's mouth, "Don't answer him!"

Tobirama took a step closer with his sword ready, "Release him, Uchiha boy," his red eyes glared dangerously, "We don't know who is this blonde but if he is wearing those Uzumaki Clan symbol, I will protect him!"

"I will not let you hurt other Uchiha," Izuna's mangekyou sharingan was ready to use.

Sasuke felt that Naruto breathing rythm becomes heavy on his hand and glanced towards him. He looked pale and hard to breathe. "Naruto..." concern was leaked from Sasuke's tone. He was frowned and closed the distance between them. Naruto's standing position was wavered before he lost his balance, Sasuke catched him in his arms. "Naruto!" Clearly, the Uchiha teenager worried. It surprised the four of the audiences. To show openly concern about other Clan in war was...unheard of.

"I... was trying to...use my chakra but..." Naruto fallen unconscious in Sasuke's arms. Five of them stayed stilled at the battlefield.

Hashirama asked, "Is he okay? I can—" He took one step closer but Sasuke looking up at them sharply.

"Don't get any closer!"

"Give him to us, then we will let you go, Boy," said Tobirama to Sasuke, exchanging glances with Izuna. Neither were move but there was silent agreement after he said that to the teenager Uchiha.

"He is not yours to protect," Sasuke hissed to Tobirama angrily. "He is mine."

Hashirama recognized the potrectiveness Sasuke showed. He put his palm on Tobirama shoulder. Stopped him to get closer. When the silver haired man looking at his older brother, Hashirama shaking his head slowly. He was stunned and a bit envy that this young Uchiha could do what he want so easily. On another hand, both head of Uchiha Clan didn't accepted it with open arms. Izuna asked Sasuke, "What do you mean, yours?"

"I don't... need to answer..." Sasuke's breathing become heavy, pale face and he followed Naruto, the next second he was unconsious too but still holding Naruto in his arms when both falling on the ground together.

"Chakra's depletion," said Tobirama as he and Izuna come closer to both teenagers. Hashirama and Madara followed them. Four of them satred at the teenagers. Hashirama suggested, "We should bring them to a better place."

Tobirama reached both boys but stopped with Izuna's hand grabbed his wrist, "What are you trying to do?" The Uchiha asked annoyingly.

"Seperating them. You can take the young Uchiha and we will take the Uzumaki boy," replied Tobirama.

"No."

Both younger brothers turned to see Hashirama with serious pained face looking at them. "We will not seperating them. We could treat both of them at the same time and place."

Izuna protested, "That's craz—"

"What do you say, Madara?" Hashirama looking at the leader of Uchiha Clan. Izuna and Tobirama turned to see Madara who keep silent for a while. "Isn't it the time we should stop this war for better future? You know this war will going to an end, why not we stop it now?" Hashirama walked towards Madara. "Did you see these boys? They didn't try to kill each other even with the symbol behind their back. Even that Uchiha boy protecting the Uzumaki!" Hashirama raised his hand to stopped Tobirama who wanted o protest, "I know what I saw, Tobirama. He was protecting, not otherwise."

Madara stayed silent and Izuna worried, he walked back to his brother. His big brother had many thing on his mind for protecting their clan. He doesn't need any additional burdens on his shoulder. The head of Senju talk like it was nothing! Izuna was fumed, "Don't listen to him, Brother!"

"If you want to protect Uchiha, this is the only way!" Hashirama stepped closer to Madara. Izuna standing in front of his older brother, scowled deeply to Hashirama. "If our clan join forces, there are no other clans will have enough strength to stand against us. [1] Let's stop this war," Hashirama raised his hand towards Madara.

The other three hold in their breathes as they saw Madara raksed his hand to reach Hashirama's. Tobirama keep silent with his brother's speechs. Izuna watch with widened eyes as their older brothers shake hands. Slowly the other fighter around them stopped their fighting. Stared at their leaders agreement to stop this long war.

—000—

"How's the migration progress?"

Madara asked Izuna as they were entered the building which was used as hospital for injured soldier for both Senju and Uchiha clan. It was a week after both clan had a truce. They were agreed to move to some place netral to minimaze anything from the past which can triggered the grudged from each clan. Hashirama came up the idea to call the leader of their join forces shinobi was Hokage because they signed the contracted with Hi no Kuni while Madara came up the name to call their village Konohagakure.

"It goes smoothly. No problem so far. Everyone from our clan and Senju already built their homes," Izuna reported flatly. Madara glancing at his brother. He remembered the first night when he agreed to join forces with Hashirama, Izuna confronted him.

"Why did you agree, Brother? Don't you remember how Senjus killed our people?!"

Madara sighed, "And don't you remember we killed theirs too? If Hashirama can offering the truce despite it, I could do the same. Besides..." Madara turned his sad face to his brother, "don't you felt tired about this war, Izuna?"

"I've known it since I can remember, what—!"

"That's what I mean. We know it ever since we can remember as a toddler. I don't want my or your future child to live in our hell and repeating our pain to lose our brothers in young age." Madara cupping his brother face gently, a smile curved in his face, "Above all, I do it for you. I don't want to lose you, Izuna. I could do this war for the rest of my life but I couldn't...I don't know what to do if I lose you in this war..."

"Brother..."

"I want you to live longer, I don't want to shorten it by sending you and use your Mangekyou Sharingan often. I don't want you to lose your light like I did," Madara closed his eyes. His sight now really poor. Everything was blur if he didn't use Mangekyou Sharingan and make it worse everytime he used it. He was almost blind. "I do it to protect you, Little Brother..."

Izuna blinked away the unsheed tears, he hugged his older brother tightly. Resting his chin on Madara's right shoulder. Izuna muttering, "You worried too much about me..."

Madara chuckled, holding him gently, "That's what brothers do, silly."

"Izuna," Madara stopped in the middle of corridor, "How about you?"

The younger Uchiha turned to his brother. If Izuna said it was okay, it will be lying because his whole life was used to hate Senju. However, considered Madara wish for Izuna's well being, he at least concluded, "Tolerable," he shrugged, "if you count this one week working together with Senju to building this village."

Madara smiles, "I'm so proud of you," patting Izuna's shoulder softly. "Have I ever let you down, Brother?" Izuna smiled happily at his brother's compliment. It never failed to make him happy since he was small. But, his smiles reduced as he remember their clan talks.

"But, how about the talk of the elders?" He turned serious. Madara carefully put his blank face, "I have not find the good time to tell Hashirama. But, I think his clan asked him to do the same." He started walked again with his brother following behind.

Although the truce going well so far, there were still some group from Uchihas and Senjus which still restless about this. Those insecures people asked Madara to do their suggestion for calmed down their worries. The suggestion which made Madara's heart twisted inside. They want a union of an Uchiha and a Senju in marriage. Generally, it's to strengthen the bond between two clans with long war history. Politically, it was for the safety of the truce. If one clans trying to ignored the cease-fire aggrement, they have a hostage from the rebellious clan. The elders of Uchiha took the decision with Senju's elders. Madara and Izuna was so busy helping the clan to moving so they almost not in the village where as Hashirama mostly stayed because he is the expert in medical ninjutsu therefore he helped the healing of the injured shinobi. Tobirama replaced his older brother, helped the Senju clan to moving in so not much different than Madara and Izuna.

"Do you think both of us will be the one to...you know, married with a Senju?"

"I'm not gonna lie to you, Izuna. There is a highly possibility for that because we are the strongest and leader of our clan," they stopped in front of a door. Whispering, "Likewise, with Hashirama and Tobirama."

Madara knocked the door then Hashirama's voice said, "Come in, Madara, Izuna."

The Uchiha brothers came in to the most exclusive room in the building. Special because the patients inside was not like anybody injured. Hashirama greeted them with a warm smile. He sat beside a futon which was occupied by a blonde teenager while the only other futon patient was the Uchiha teenager who was appeared suddenly in the middle of battlefield. Both wearing simple white kimono. Tobirama sat behind his brother.

"How are they?" Madara walked towards Sasuke's futon.

"Their chakra level finally normal. So, they will wake up in any minute," Hashirama explained. "We sent word to Uzumaki clan but no one said they knew this Uzumaki boy. Especially with his blonde hair. It is doubtful he is an Uzumaki."

"He did said his hair is from his father's and said his mother's was red hair," Tobirama adding, "We can say his mother is an Uzumaki."

"And the Uchiha boy?" Hashirama asked the Uchiha brothers.

"No one knows him. His name, Sasuke, didn't ring any bell in Uchiha," said Madara. "We only knew Sasuke which is from Sarutobi Clan."

Hashirama sighed, "I see."

Four of them keep quite for several minutes before Madara askes Hashirama, "How's the Hokage election?"

"Uh...it's..."

"Brother was elected to be Hokage," said Tobirama. "The people from Hi no Kuni accepeted the villagers choice."

Madara and Izuna stayed silent. It was predictable with the rumours going on even from Uchiha Clan. They said Hashirama was more trust worthy than Madara. Not that he minded, Madara even agree to those opinion about his childhood friend's nature. He also never want to be a leader. He only done it for protecting Izuna. That alone was more than enough for him so he didn't care if Hashirama become Hokage.

Tobirama's next word pull Madara from his train of thought. It sounds hesitated, "However... our elders make a decision to rest assured the bonding of our clan."

"I take it both of you have been told about the marriage?" Asked Izuna.

Hashirama looking at them confused, "What marriage?"

The other three exchanging glances before explained to Hashirama about it. To say he was surprised was understatement. His eyes widen as he loudly voicing his opinion in one word, "WHAT?!"

"Uh! What?! What?!" Naruto suddenly sitting up, waking up with panic expression when he spreading his gaze around the room. "Oh, only Grandpas and Madara..." he went back to laying down but in another second he found it's weird then he sat up again quickly. Looking at each four of them cautiously as he remember what happened before he lost concious.

"Good. You're up," Tobirama stated as he standing beside Hashirama who cheking up the blonde with quick examination.

Meanwhile, Madara and Tobirama glancing at Sasuke who was still closing his eyes. Madara said to the teenager Uchiha, "Why don't you stop your pretending to be sleep?"

Sasuke opened his eyes, looking at Naruto who sighed in relief, "Sasuke!" Then glancing at the audiences as Hashirama checking him up before he was confirmed that both of them okay.

"Both of you have explanation to do," Tobirama started, "Neither in Uchiha and Uzumaki Clan claim you as their family. No ones here know you."

"No surprises there." Commented Sasuke.

"Enlighten us." Izuna said. Madara added, "How did you, both of you suddenly appeared in the battlefield?"

Hashirama picked up something from the table beside Naruto's table. It was Naruto's hittai-ate. The older Senju asked, "This symbol is Konohagakure's. How did you have it while this village only founded just one week ago?"

Naruto looking back at Sasuke who glance back before he turned to Hashirama again, "I'm not sure... but I think Sasuke know more about this..." All the attention then focused on Sasuke. Naruto said to his friend, "We have to tell them, Sasuke."

"No. We are not. It could change the history."

"Not that it was good history, right? Maybe it would change for better future." Naruto said painfully. "We can not do this alone. We need them to help us if they can help us back to our time. Itachi once said to me don't try to take it all by myself."

It silenced Sasuke effectively. Mentioning Itachi was his weakness as he remember his brother last word before edo tensei was gone. Itachi admitted his one mistake was to left Sasuke out. Not letting him know the situation while there was a possibility Sasuke could change their parents mind to stopped the coup d'etat. Sasuke still considering all the good and bad while Naruto's stomach protested loudly.

"Aah! I'm hungry!" Naruto complained.

Hashirama laughed, "Well, it was to be expected, you were out for one whole week!"

"What?!" Naruto cried out. Sasuke sighed, "Alright, I'll tell you what I think it's happening but let us eat first."

Naruto immediately requested, "Is there any ramen?"

—000—

"So, how do I start?" Sasuke asked lightly after he and Naruto done eating. The other four now sitting with two on each side of their beds. Uchiha brothers on Sasuke's bed and Senju brothers on Naruto's bed. Izuna replied, "Why don't you started with introduction? You seems to know our names although the blonde didn't know my name."

"Yeah, who are you?" Naruto tilting his head.

Izuna look at the blond, "It's rude to asking someone name without mentioning yours first, Boy."

"Well, I'm Uzumaki Naruto," Naruto answered easily, "You?"

"My name is Uchiha Izuna, Uchiha Madara's younger brother," he crosses his hands on his chest.

"Wow! Madara had a brother? I never knew that!"

"Oh, and what do you know about me?" Madara curious. He knew he was famous as Hashirama reputation. Besides mostly knew Izuna is his brother if the knew Madara's name. So, how come this boy only know Madara but not knowing about Izuna at all? He saw Naruto opening his mouth to answer but Sasuke cut in.

"We will get into that in a second. Before that, all of you should put your mind open because what we will tell you... it's not a happy one and more tragedy involving four of you. Either you trust our words or not it's your choice. Just don't interrupted us until we finished."

The four of them exchanging glancing before Hashirama nodded, "Go on."

"I'm Uchiha Sasuke and he is Uzumaki Naruto. We were born in Konohagakure but we were not born in this era but decades later from now."

I'm listening "Machigai Sagashi" OST from J-Drama called Perfect World while writing this story. The lyrics fits HashiMada and TobiIzu situation because they were at war and inspired me a lot. Hence, the title similar to the drama but the story is not. I didn't watch the drama only like the soundtrack.

Thank you for reading! Please let me know what you're thinking about this story! Leave me a review if you don't mind! It's my first time ever writing about time travel story so any feedback would be a great help!
