Naruto: Unifying the Ninja World, Invaded by Naruto’s Team

"You now understand the Empire's strength. Join us? Fight the Otsutsuki together?" Ryuji asked.

"Of course I want to! There's so many…" Boruto exclaimed excitedly.

But Future Sasuke pressed his head, serious. "Boruto, quiet. I'll handle this."

He faced the three present. "Pardon my boldness, but after joining the Empire… what happens to Uzumaki Naruto's village? Does it vanish?"

Ninja World Naruto's face froze, then smiled. "The village disappears. It's an outdated system—looks nice, but many remain poor. The Empire's different. Its strong growth ensures hard workers live well, with a minimum guarantee for basic living standards.

"No more corrupt daimyo or nobles. Everyone's happy, prosperous. You've seen this in the Empire these past days, right?"

"What about your original world?" Future Sasuke asked.

"Hmm… that world's probably decayed. To fight the Otsutsuki, His Majesty moved chakra, natural energy, and more from our original world here, making martial arts and ninjutsu training easier, strengthening the Empire overall." Ninja World Naruto said.

"Moving chakra, natural energy, and more here… that's possible?" Future Sasuke was stunned, brows furrowed.

It felt eerily similar to the Otsutsuki's methods—one for individuals, one for the collective.

The difference was vast, but he didn't want his world to face this. "This might be right, but ordinary people wouldn't accept their homeland decaying and collapsing."

"It's sad at first, but you get used to it living in the Empire. You've felt the difference between the Empire and your world, right? Sazu, Boruto, join us.

"Fight the Otsutsuki together, make the Empire stronger, ensure true safety for all. That's His Majesty's goal. We alone might not be enough.

"But with countless us, hope can become reality." Ninja World Naruto extended his hand to Future Sasuke.

"Your wishes and ideas are great… but I refuse. I can't accept my hometown vanishing or my birthplace collapsing." Future Sasuke shook his head.

Boruto added, "Yeah! It's where we were born and raised! How could we let it collapse?"

"I see… then you won't use Karasuki to take us to your world, Uchiha Sasuke, Uzumaki Boruto." Ryuji said flatly.

His voice wasn't loud, but it struck Boruto and Future Sasuke like thunder, jolting their hearts.

Even Imperial Naruto and Ninja World Naruto looked shocked.

"Uchiha Sasuke? Sasuke? Your Majesty, what do you mean?" Imperial Naruto asked, stunned.

"Don't get it? These two are Uchiha Sasuke from another world a decade later and Naruto's son, Uzumaki Boruto!" Ryuji said.

"You knew!" Future Sasuke exclaimed, shocked.

"Waaa! How? How'd you know?" Boruto panicked, pointing at Ryuji.

"Sasuke and my son?" Ninja World Naruto gasped, pointing at his nose.

Imperial Naruto's mouth hung open.

Future Sasuke's brows tightened, growling, "Idiot! What do you mean me and your son? It's you and Hinata's kid!"

"Huh? Me and Hinata's kid? Me? And Hinata?" Ninja World Naruto yelped.

"I married Hinata in your world? And had a kid? Wow! No wonder Boruto asked about Hinata! It makes sense!" He recalled their first night at his place, dawning realization.

Imperial Naruto's expression quickly normalized. "Married to Hinata? That only happens in Little Naruto's world."

"Aaa! Is this really okay? Dad here knows future Mom and me!" Boruto fretted.

"Things have escalated this far; forget Karasuki…" Future Sasuke clutched his face, exasperated.

"Future Sasuke and Boruto, didn't expect to meet people from the future. Weird but cool… hahaha…" Ninja World Naruto laughed, hands on hips, then asked curiously, "Can you tell more about your world? I've got a kid, but Sasuke? Who'd he marry? Kids?"

"Of course! Aunt Sakura, and their kid's Sarada." Boruto said.

"Sakura? Nice outcome. Sakura sacrificed so much and got rewarded. Sarada sounds like a girl's name." Ninja World Naruto smiled, relieved, not too upset his childhood crush ended with another.

Years in the Empire made Hinata, undeniably, his closest opposite-sex friend besides family. 'If I must marry in the future, Hinata might be a good choice,' he thought.

"Right, Sarada's a girl, and in our world, Dad's the Seventh Hokage." Boruto said excitedly.

"Seventh Hokage! Awesome! Future me's amazing!" Ninja World Naruto danced gleefully.

Imperial Naruto cleared his throat. "Little Naruto… enough. His Majesty's watching; don't be rude."

"Aaa… sorry, Your Majesty. I got too excited. Meeting future people—didn't expect it." Ninja World Naruto said sheepishly.

"No matter." Ryuji shook his head, eyeing Future Sasuke. "Back to the topic—you'll refuse to take us via Karasuki, right?"

"…" Future Sasuke paused, then resolved. "Sorry, I don't want unpredictable events in our world. We'll refuse."

Ryuji didn't anger, only smiled faintly. "Fair enough… then it's like this…"

He raised his right hand, fingers claw-like. "Genryu Mōkyō Ken!"

An invisible wave spread.

Future Sasuke sensed danger, grabbing Boruto to flee, but his body froze.

Their expressions turned vacant.

"Obey my command, Uchiha Sasuke, Uzumaki Boruto."

"Yes… Your Majesty." they knelt, reverent.

◆━◇◆◇━◆

Days later, Empire outskirts.

Ryuji, Imperial Naruto, Sasuke, Hinata, Might Guy, Neji, Ninja World Naruto, Sasuke, the Sage of Six Paths, Boruto, and Future Sasuke gathered.

Empire and ninja world members focused on Boruto and Future Sasuke.

"Finally heading to the future world? Wonder how many Otsutsuki are there—hope their strength doesn't disappoint." Imperial Sasuke said arrogantly, arms crossed.

"Shouldn't disappoint. Didn't future you say they defeated Momoshiki, far stronger than Urashiki?" Imperial Naruto said.

"Urashiki? Just Pseudo-Six Paths trash. Even if much stronger, so what? Defeated by this future trash, they can't be that strong." Imperial Sasuke sneered at Future Sasuke, then mocked Ninja World Sasuke. "Your future self's like him?"

"Shut up! Trash like that dares compare to me? Wait till my power grows, absorbing Indra's strength—you'd better watch out." Ninja World Sasuke retorted, glaring at Future Sasuke with equal disdain.

Their attitude made Future Sasuke, under Genryu Mōkyō Ken but retaining normal thoughts, feel awkward, his face twitching. "These two brats underestimate me? Wait till you're married—let's see how strong you are.

"You've no idea how hard it is to maintain a family, keep marital harmony! As you age, things naturally weaken! Do you brats get it?"

"Uncle… don't talk about Uncle Sasuke like that… He's really strong; Urashiki just drained his chakra." Boruto defended.

"His chakra got drained by trash like Urashiki—how strong is he?" Imperial and Ninja World Sasuke said in unison, exchanging glances, snorting, and turning away.

"Stop bickering, you two. We're facing real Otsutsuki soon; we'll need to cooperate!" Ninja World Sage of Six Paths shook his head helplessly.

In the Empire for a year and a half, he stayed behind the scenes, known to few.

But accustomed to the Empire, he genuinely hoped it would thrive.

The ninja world was gone; the Empire mustn't fall!

The true enemy, the Otsutsuki, required collective effort.

"Right! I'm fired up! This time, I'll fight those Otsutsuki all-out! Aaaa! This is youth's spirit!" Imperial Guy roared excitedly.

"With you all, I feel at ease." Imperial Hinata's star-and-sea-blue eyes sparkled.

"I want to test the Otsutsuki's abilities." Imperial Neji said eagerly, his eyes glinting blue.

"Let's begin, Boruto, future world Sasuke." Ryuji said.

Boruto pulled out the pink turtle Karasuki.

Future Sasuke told Karasuki, "Take us back to our original world."

"Command received… initiating return journey…"

Karasuki glowed, enveloping everyone.

Countless lights appeared, and next—

They emerged in a strange world.

Lights kept flashing.

◆━◇◆◇━◆

They appeared in a different forest.

"Mission complete." Karasuki said, closing its eyes.

Looking around, Ninja World Naruto said excitedly, "This is the future world? Wonder what Konoha's like here—can't wait!"

"Hmph! Just a continuation of an outdated system." Ninja World Sasuke scoffed.

"Chakra and natural energy concentration here's far less than the Empire…" Imperial Naruto sensed.

"Future world! We're here! Otsutsuki, we're coming!" Imperial Neji said eagerly.

Ryuji, expressionless, took Karasuki from Boruto, then flew skyward with everyone.

They spotted a nearby village.

Seeing a village vastly different from the ninja world—far grander buildings and a massive Hokage statue—they grasped the situation.

Ryuji pointed at the ground: "Genryu Mōkyō Ken!"

Boruto and Imperial Sasuke's expressions briefly dazed, then showed relief upon recovering.

"Thanks to Big Brother Naruto this time. Without him, defeating Urashiki wouldn't have been so easy." Boruto said.

"Indeed… didn't expect that world's Naruto to be so strong. Let's go, Boruto. Guard Karasuki well—don't let it fall into others' hands, or uncontrollable things might happen." Future Sasuke warned.

Boruto looked at the stone in his hand, nodding earnestly. "Don't worry, Uncle Sasuke. Once home, I'll hide it where no one can find it."

"Let's head back."

Future Sasuke finally smiled, leading Boruto to Konoha.

In the sky, Ryuji and the others watched their retreating backs, quietly descending to follow.

As they walked, their appearances changed drastically.

Soon, they blended in as unremarkable men and women.

Konoha, Hokage's office.

Future Sasuke stood before Hokage Naruto, recounting his space-time journey.

Hokage Naruto's expression shifted, looking odd. "Crossing to a past world, ending up in a bizarre one? Two mes? One two meters tall, transforming into a three-meter giant, another like me now, using Wood Element and Sage Wind Mode?

"Urashiki easily beaten by that strong me? Sasuke… this trip's wild. If you didn't tell me, I'd think you'd gone mad."

"I didn't expect this either, but the outcome's good. Urashiki's done for." Future Sasuke said. "But that world's you was insanely strong—no Sage of Six Paths power, yet I doubt he'd lose to us with Six Paths power back then."
