"How's Sasuke and Naruto?" Asked Deidara. He closed the door and went inside to Itachi's side.

"His wound was extensive. Even with Asura's healing chakra inside me and his medical ninjutsu, it will take a while for this Naruto to be back to normal," replied Naruto. He sat at the edge of the bed where teenager Naruto was laid down. He had changed his clothes after having a bath and borrowed a light yellow kimono that was used for sleeping. Sasuke who was standing beside him has changed his ANBU uniform as well. He wore a dark grey light yukata. Both kimonos belonged to Sasuke and Naruto in the future. Their unconscious teenage selves borrowed Menma's clothes since the size fit them. Minato who was standing around near the bed patted the teenager Naruto's hair.

"And Sasuke?" asked Itachi. His dark red kimono was tied by black obi. Deidara on his right side contrasted him with white kimonos and red obi. Menma on Itachi's left side changed to a black shirt and white shorts. They were standing at the end of teenager Sasuke's bed. They were in an extra bedroom with twins beds. It was a precaution to not confuse Yuma when he saw two sets of his parents.

"It's hard to tell. When I healed my Sasuke's bleeding Rinnegan, he was still conscious," Naruto frowned looked at teenager Sasuke. "He should have a faster recovery."

"But, your Sasuke only has one Rinnegan," Minato pointed out. Itachi added, "We don't know what happens but our Sasuke has two Rinnegans. The effects could be different."

"Uncle Itachi, Grandpa, are you sure they are my parents?" Menma voiced out his opinion. They looked at the boy. His doubt was written on his face.

"I help Dad change their clothes but… in their belongings, he," Menma looked at the teenager blond, "doesn't have Grandma's pendant. The one she made for me and Dad." He took out his pendants from his shirt.

Itachi looked thoughtful, "Minato-sama said they didn't have his mark on their body either."

Minato confirmed, "Indeed."

"And they are teenagers," Menma ended with a frustration leaked in his voice. "What makes them look like teenagers? We all know if they used henge, it will need the user's chakra and concentration to maintain the shape we want. And they are unconscious. It's impossible to do that. Not to mention the critical condition he had," Again, he meant, the teens blond, "What kind of Jutsu that put them in their teens' body?"

They have no answer for that so they remained silent.

Sasuke stared intensely at the unconscious teens. He felt he missed something. That Naruto. He saw him before. But, where? That Naruto's outfit was exactly like his Naruto 5 years ago. Black-orange jacket with black pants. Was that the reason he felt he saw him before?

No.

Sasuke was certain he saw that bleeding outfit recently. At that thought, his eyes widened before frowning. Ah, yes. Recently.

"I've seen him," Sasuke's mismatched eyes focused on the unconscious teenager version of Naruto.

Naruto looked up at Sasuke, "What?"

"The vision I saw from my Rinnegan. I saw Naruto bleeding and dying, it's matching with this Naruto's condition," Sasuke touched his Rinnegan. "I remember feeling sorrow and sadness which is not mine but I felt it in my soul. And it felt twice excruciating than what I thought."

Itachi caught the unsaid, "You are saying that this Sasuke sends you the vision of dying Naruto through Rinnegan? Is that even possible?"

"The only other Rinnegan users I have ever met was Madara in my time. The one who started the Great Ninja War 4. His Rinnegan ability is different than mine." Sasuke started, "I will not rule out anything regarding Rinnegan so, yes, there is a possibility of that."

He added, "Bear in mind, there are only 3 Rinnegans owners I've known. Rikudou Sennin, Madara from my time and myself. Rikudou Sennin had his Rinnegan awakened after he lost someone dear to him. Madara awakened his Rinnegan himself by implanting Shodaime's flesh into his. My Rinnegan was given by Rikudou Sennin. But, then it was gone when Naruto and I went back to the past. It happened to Menma as well. The journey through time degrades the Rinnegan. However, Indra and Asura helped me awakened mine."

"Indra and Asura?" Menma was shocked.

"Yes, they appear when two sets of their reincarnation harmonize their chakras. It happened when we activated the Jutsu to go back to our future," Sasuke explained what happened when Indra and Asura appeared.

Naruto said, "You were already gone back to your time when it happened, Menma. So, you don't know this. Even Grandpas and Madara or Izuna were surprised. We didn't know it back then."

Itachi concluded, "So, if four of you," he meant the reincarnations in this room," harmonize your chakra, Indra and Asura will appear?"

"I believe so," replied Naruto.

"They can awaken rinnegan?" The Godaime Hokage asked again.

Sasuke elaborated, "They can but there are requirements for that. For instance, Indra said they can help accelerate my Rinnegan awaken because I have Naruto's chakra transferred into me and Shodaime's cells are transplanted into me as well. Not only chakra and some DNA of Asura's reincarnation needed but also the feeling of lost someone dear."

"Who did you lose?" Deidara asked.

Both Sasuke and Naruto glanced at Menma at the same time. Everyone knew the answer immediately. Menma gasped. He snapped his head at Sasuke.

"It's you, Menma," Naruto said gently.

"At that time, Sasuke may not cry on the spot. He wants to maintain his "cool father" image, you know. Because you are our son," Naruto looked at Sasuke fondly, "Do you remember me crying when you are gone, Menma? Sasuke felt the same. I felt it through our bond."

Menma stepped closer to Sasuke who reached out to put his palm on the nape of the said son. He locked eyes with Menma's mismatched eye. Their Rinnegan on the opposite position. Sasuke's was on the left and Menma's was on the right. He said with concealed sadness but Naruto felt it too, "We thought we will never meet you again."

The memory about that time appeared and Menma remembered it vividly as if it happened now. He had wanted to call Sasuke but it was going in vain. Tears brimmed on Menma's eyes as he whispered to Sasuke, like how he wanted to call him back then, "Father…"

There was silently surprise from Itachi, Deidara, and Minato to hear that. Unbeknownst to Sasuke and Naruto, Menma never call Sasuke in this era with 'father'. When Sasuke hugged Menma, the trio realized Menma was closer to this Sasuke than theirs. It was not a spur of the moment like the time Sasuke kissed Menma's cheek because of Yuma's questions. Menma was closed to this Sasuke.

Itachi and Deidara exchanged a glance before the blond gave a suggestion. "Look," Deidara grabbed their attention, "If either of them won't wake up tonight, why don't we hit the hay? It won't give us anything if we just stand here all night. We need an answer but they have to wake up first."

They were agreed and started going out of the room one by one. Naruto asked about Yuma, Deidara told him that the boy sleeping with Koumi. Ryuichi still had his bath because he was the last one to take it. They let their guests from other future have it first. Then, Menma asked his uncle, "Uncle Itachi, can someone fill my position for the next mission?"

Itachi glances at his nephew and teenagers on the bed before nodding. "I'll send Ryuichi for the mission," he said and stepped out with his husband. After Naruto reached the door, he turned back to find Menma was not moving from his position when Sasuke broke their hug. Menma was between the beds. The boy just stared at the inanimate teenagers. Naruto wanted to comfort him but Sasuke tapped his shoulder and shook his head. He saw Minato give him a nod then they went out.

—000—

Hours have passed.

A pair of Rinnegan eyes opened slowly.

—000—

An hour before the sun was up, Sasuke snapped his mismatched eyes open. He sensed it like he did when he got the vision. Slowly, he sat up and looked at the door. He was inside the room of their altered egos. Naruto followed his suit.

"He wakes up," the blond sensed the chakra of teenager Sasuke.

Both of them head to the extra bedroom where the teenagers stayed last night. On the way there, they bumped into Minato who felt the chakra as well. When they opened the door. They saw Teenager Sasuke sitting, staring at Menma who was sitting on the floor but standing up cautiously after the door was open.

The tension was thick. Especially, when those Rinnegans left Menma and landed on Naruto. The blond let out a silent gasp. Teenager Sasuke stared at him without blinking for a long time. Since he never saw his Sasuke have both Rinnegans, the feeling of that gaze was overbearing. It was an intense gaze.

Yet, that gaze broke when a pair of Rinnegans moved to another bed across him. His voice has a tint of sadness when he called out, "Naruto…"

As if it just broke an unknown spell, Naruto sensed Teenager Sasuke worried about Teenager Naruto. It put him at ease so he entered the room. Followed by Sasuke and Minato. Naruto reassured him with a smile, "It will take time for him to wake up but he is out of danger. Your Naruto is safe."

Teenager Sasuke stared at Naruto again. It started to annoy Sasuke, so he asked, "What happened? Why your Naruto was dying? Who hurts him? Aren't you two on vacation? And why do you two become a teenager?"

Both Sasuke locked their gaze. They maintain void expression but the intensity of their Rinnegan eyes was betrayed them. Naruto stepped closer to Teenager Sasuke to ask, "How're your eyes?"

The teen glanced at Naruto again before his hand raised to touch his eyes. Minato noticed there was something off from his son-in-law. He has his guard on. It was understandable because it was his first time to meet their guests from other futures. But, it didn't make sense since there was Minato and Menma. His son-in-law may not amiable by nature but Minato knew him enough to know Sasuke would be relaxed around his family. Including around Minato. They had their family outings several times and they were on good terms.

"Sasuke, what happened with my mark on your body? I can't teleport to you because it's gone," Minato inquired.

Teenager Sasuke snapped their eyes on Minato, "You marked me, Yondaime Hokage?"

Minato frowned. The tone of younger Sasuke's voice implied that he didn't know about the mark. It was impossible. Sasuke was the one who asked to be marked. Just in case something happened again. Minato noticed the teens Sasuke didn't answer their questions and he even asked them back. He ad bad feeling about this. "What do you remember, Sasuke?" Either it was de-aging Sasuke and losing his memories or…

"What year is this?" That teenager asked.

They gasped in alarm.

That one question ruled out their previous doubt due to the implication. It was not memory loss. This Sasuke recognized Naruto from the scroll. It meant he read the sacred scroll. In addition, he didn't question who is Menma or why Minato looked old. He didn't even faze to meet the guests from another future.

Menma told him the exact year.

"I see," younger Sasuke muttered.

It was like he knew them, expected them but never met them.

"I'm in the future…" Teen Sasuke closed his eyes with a frown.

"You are from the past?" Naruto was shocked. "From the year you read the sacred scroll?"

Teen Sasuke looked at them one by one before he replied, "I've read the scroll when I was 12." The others were lost for words when he continued, "I come from the future which was formed by the changed in the past due to Menma's arrival."

They were stunned but Minato quickly, "Menma, wakes up your uncles." His eyes were on Teenager Sasuke, "We have guests from another future once again."

—000—

After breakfast, they were in the living room with teens Sasuke. Koumi took care of Yuma for the day. Clock-wise there was Itachi on the head of Chabudai (short-legged table), Deidara, Menma, Teens Sasuke (he sat across Itachi), Naruto, Sasuke, Minato. They still wore their sleep-wear.

"Sasuke," Itachi started, "I mean, the teenager one." He clarified after two Sasukes glanced at him. "I know this young adult Sasuke is the one that described on sacred scroll. He comes from another future," he stared at the youngest Sasuke, "But, you are saying that you are not our Sasuke."

"I'm not Sasuke from this era," the teenager admitted.

"Would you please enlighten us about how did you do time travel?" Itachi inquired.

It was not hard to recognize that this Sasuke telling the truth since all the pieces of evidence they found directed them to this conclusion. The newcomer Sasuke and Naruto have no Minato's marks. No Kushina's pendant. They were teenagers and Sasuke has Rinnegans. The big question was: how they did time travel?

"It was unclear how it happened. One thing I was in a rescue mission and the next thing I touched Naruto, we are in the future," he replied.

Naruto gasped, "It happened to us too. When I touched Sasuke, I mean, my Sasuke, we were brought here."

Minato looked at them thoughtfully, he suggested, "Why don't you tell us what was happening before you touched Naruto and arrived here?"

"I was on a rescue mission. My team is needed to help Kakashi Team in a crisis. While fighting the enemy, Naruto protected our client. I saw…" Teens Sasuke frowned lightly and was silent for a second before he composed himself to continue, "I saw a massive explosion in Naruto's direction. When I reached there, he was the target of that explosion. Then, as soon as I held his body, there was a chakra around us and we arrived at this future."

Explosion? Sasuke felt something was off when he heard the explosion. But why? He couldn't remember. Vaguely, he knew it was crucial but he couldn't remember why. However, he took note mentally to visit this thought later. Sasuke emphasized, "You recognized my Naruto," he locked eyes with his alternate ego.

"I've read from the scroll that the original Naruto is a Jinchuriki of Kyuubi and received Yang Power from Rikudou Sennin. I assumed that was caused by his yellow chakra at that time," he observed. "It's in my understanding that there are no Jinchuriki in this era due to Shodaime Hokage's legacy to never seal the bijuus," he glanced at Minato and Itachi. "Am I wrong?"

Minato answered, "No, you are not wrong. It's true."

Deidara was curious, "So, there is a sacred scroll as well from your time? Nidaime Hokage made the same decree?"

"No," Teens Sasuke shook his head. "There is no such a decree like the one in this future. No one was obliged to try to open the scroll. It's not a sacred scroll. It's a secret scroll in my family. My mother had it from Grandmother Tsubaki and she give it to me."

"Grandmother Tsubaki gave it to Mother? She died after giving birth to our Mother."

"Not in my time," said Teens Sasuke. "Their interference in the past changed history and this future is the result. Likewise, Menma's arrival changed the history of this future and create the future where I come from," he glanced at Menma who was startled. "Grandmother Tsubaki was alive. She was given the scroll by her father, Izuna Senju, when he died."

"So, there are differences between our timelines," Deidara concluded.

"You can say that."

Menma asked, "What's the other differences?"

"First of all, after they were back to their future," he meant Original Sasuke and Naruto, "Shodaime died when he rescued his son, Hiko."

"It's the same with our history," Menma muttered.

"But, Madara didn't have miscarriage like he did in your history. Mito Uzumaki helped him through his crisis time with sealing Jutsu. He did almost had a miscarriage but he ended up giving birth prematurely again like he did the first time. Hiko's sister was born. Healthy."

"Hiko had a sister?" Naruto asked in awed. He nodded, "Her name is Mayumi Uchiha."

"Did Madara live for a long time?" Sasuke asked.

"No. He died 6 years later."

Naruto asked worriedly, "Has someone killed him?"

"His belly scar from giving birth to Mayumi was damaged when he was on one mission. There was no medical-nin as good as Shodaime at that time. No one could heal him. Madara died of blood lost."

"It's not that different than our history," Itachi commented. "Madara Uchiha indeed die of blood loss due to a poison, not a damaged operation scar."

Youngest Sasuke continued, "The other differences between our timeline is Nidaime and Hiko didn't fight each other after Madara died. They were alive. Hiko died at 32, not 17 like in your history. Nidaime died in the same year after Hiko's death. However, not because he fought his nephew."

"How did they die, then?" Sasuke narrowed his eyes.

Teens Sasuke closed his eyes, "That year, Toshizo and his son, Nawaki, was died on a mission. Toshizo was like a dear brother to Hiko so his death awakened Hiko's Rinnegan. He used Rinnei Tensei to bring Toshizo back to life in exchange for his own life."

The audience was surprised, but Sasuke was not. He thought it was impossible for Hiko to know immediately about Rinnegan's ability the moment he had it. Sasuke knew it because Rikudou Sennin passed down the knowledge about it when he got his Rinnegan first time. Madara (Villain) had Rinnegan for a long time to analyze the abilities behind the eyes. Yet, Hiko knew Rinnei Tensei already. At that era, Tobirama Senju was the only one Sasuke told about Rinnegan's ability.

Sasuke had a suspicion Nidaime told his nephew about it. Considering Hiko's Rinnegan was awakened when Toshizo's death, it was safe to assume that Hiko loved Toshizo dearly. And if Hiko was told he could bring back Toshizo alive with his Rinnegan, Sasuke was sure he would do it in a heartbeat. It was not hard to predict Uchiha behavior if it's about their loved ones. Not to mention, Hiko was Shodaime's son as well. Shodaime was a compassionate man like Naruto. Based on all of that, Sasuke believed Hiko would use Rinnei Tensei should he knew. In addition, Sasuke knew Nidaime enough to know Tobirama would do anything in his power to prevent disasters. Even at the cost of his nephew's life. Rinnegan will create a war over the possession of the eye. Nidaime must be thought he need to destroy it. Sasuke bet Nidaime told Hiko about Rinnei Tensei so after Hiko died, he burned those Rinnegan. His eyebrows frowned deeply. "How about Nawaki? Did Hiko bring him to alive too?"

"No. Only Toshizo Senju," the youngest Sasuke confirmed.

It meant Tobirama tried to keep the reincarnations of Indra and Asura untouched so the time for Sasuke and Naruto to be born as the next incarnation will not be disturbed. He let his grandson die like the history from this future so he or Izuna could pass down the scroll about time traveling to their granddaughter, which is Mikoto Uchiha. Itachi and Sasuke's mother. They tried to keep the timeline unchanged in order to preserve their lineage to be similar to Menma's lineage in this future. Izuna probably watched Shiki's movement after Nidaime died and kill him (by himself or order someone else) when the time come. Which was one year before Teen Sasuke was born.

"And Nidaime? How did he die?" Sasuke asked again.

"There was an attempt to assassinate Mayumi in the same year. She was usually protected by her brother but that year, Hiko gave up his life for Toshizo. Nidaime was there and he protect her until his last breath," explained Teens Sasuke.

He told them that Tsubaki was survived, unlike in this future, because her parents anticipated Mikoto's birth. They were well-prepared so it ended well. Tsubaki died when Teen Sasuke was 12 years old. On her death bed, she gave Mikoto the scroll to give to her grandson when he reach 17. However, before she mention the name of which grandson, she died.

"Mother thought it was for my brother because he reached 17 four years ago but…"

"Another me couldn't open it," added Itachi.

He nodded, "So, mother gave it to me and it's open in my hand. I read it," he glanced at the original Sasuke and Naruto. "I know about Kaguya, Uchiha's massacre, Madara Uchiha, and," he stared at the other black-haired teenager, "Menma."

"Why Menma is written there?" Naruto confused. "I don't get it. Why did Grandpa Nidaime or Izuna put Menma in the scroll?"

"I believe either Nidaime or Izuna write it for him so he will not leave his Naruto for whatever reason he deemed right. I think they hoped that you are not repeating my or Menma's decision to leave our Narutos for what we thought was right without telling them." Sasuke explained. "They tried to avoid any suffering for your Naruto." Sasuke stared at his younger self.

"He should not have any suffering from me because I never leave and—" Sasuke stated calmly but there were sadness undertones in his voice, "—he is not 'my' Naruto."

"What?!" All eyes on Teen Sasuke. Did they hear it right? Sasuke and Naruto were not a couple?!

"Naruto and I are not in a romantic relationship." He confirmed. "He is just my childhood friend."

Everyone was alarmed. Even Sasuke didn't conceal anything as his eyes widened in disbelief! Just childhood friend? FRIEND?! How can that happen?

Sasuke never had any day go by without thinking of his Naruto. Even when he left Konoha and trained under Orochimaru's tutelage. Even during his quest to revenge his clan. Even in his dying moment after Madara stabbed him! Older Sasuke from this era left Naruto for over a decade but it was for the blond's protection. Not because he wanted it so Sasuke was able to sympathize. But, this younger Sasuke said something so foreign for everyone to comprehend.

Naruto frowned, "Why? Do you have someone else in your era?" He was annoyed at the thought of Sasuke with anyone else. Albeit, that Sasuke lives in another timeline. It was an unpleasant thought and Naruto disliked the notion.

Teen Sasuke looked surprised. He didn't expect that accusation at all, "I'm single."

"Then, why—" A horror gasped escaped Naruto's lips, "Are you saying my other self, he… is he… is he… in love with someone else?"

Naruto doubtful it was the case. He never thought he would be with anyone else. Indeed, he thought he had a crush on Sakura but Sasuke took his heart in a heartbeat without Naruto realizing it. He and his alter counterpart were coupled with both Sasukes. Automatically, he thought the teenagers were a couple like them as well.

No one expected that they were not a couple.

Minato frowned at his alter son's question. As long as he remembered Naruto's childhood, the boy always is with Sasuke. He remembered clearly Naruto kept telling 'Sasuke this', 'Sasuke that'. All the time. All his life revolves around Sasuke. Itachi remembered the same thing about Sasuke. When the two of them were officially together, it came as no surprise to anyone in Konoha. Everyone foresees their marriage. It was unthinkable to see Sasuke without Naruto and vice-versa.

Teen Sasuke opened his lips, "Naruto is…"

Okay, this is maybe a little bit confusing if you forget Perfect Time already. I will suggest you read the prequel again, chap 13-14 because that chapter contains Menma's future history.

To recap,

Toshizo and Tsubaki : TobiIzu's children

Hiko and Mayumi: HashiMada's children

Shiki Uchiha: Indra's reincarnation after Madara, before Sasuke. The grandson of Takumi Uchiha (Kagami's uncle). Shisui's father.

Nawaki Senju: Asura's reincarnation after Hashirama, before Naruto. The grandson of TobiIzu. Older brother of Tsunade.

If you are curious, yes, yes, yes, this fanfiction has 3 sets of SasuNarus. 3 sets. Yes, like 3 Spidermans. LOL. I've got the inspiration for this story after the rumor of 3 Spiderman will appear in No Way Home last year. I thought, "Well, I want to have 3 sets of SasuNarus in my story."

To avoid confusion, I will call them:

SasuNaru Ori: SasuNaru from Perfect Time

SasuNaru Pro: SasuNaru in Menma's future aka the one in the setting of this story

SasuNaru Lite: SasuNaru from the future created by Menma's arrival in the past

Future Pro: the setting right now, Menma's future. I call it Pro coz it was created after SasuNaru changed the past in Perfect Time. It has a better future than the canon, that's why it's Pro. So, SasuNaru from this era will called as Pro as well.

Future Lite: the slightly different version of future Pro coz Menma went back in time and change history as well but not as big as SasuNaru did. Hence, the lite version of Pro.

Future Ori: The canon one but ignored epilogue.

If you have any questions, just ask me in the review and I'll try to explain again!
