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

"Dad!"

"Naruto!"

Boruto and Future Sasuke stared at the figure.

Yes! This was the Uzumaki Naruto they remembered, not that muscle monster!

Our Naruto isn't like that!

"These two? You could say they're my big fans. Found them interesting, so I brought them along." Imperial Naruto explained, smiling, his muscles still pulsing.

"So, Big Brother Naruto's fans, but why are their bodies so scrawny? That's not right! Now that everyone's an Empire citizen, they should train martial arts properly, strengthen their bodies—that's the way." Ninja World Naruto grinned, laughing.

"Uh…"

Hearing "strengthen their bodies." cold sweat dripped from their foreheads.

'Does this mean we have to become muscleheads too? Spare us!'

Boruto smiled awkwardly. "Um… we know, we'll try harder in the future."

"What're your names? For some reason, you feel really familiar." Ninja World Naruto asked.

Ninja World Hinata spoke up, "Naruto-kun feels the same? I also feel very close to this blonde young man…"

Hinata gazed at Boruto, her face full of maternal warmth.

"Some folks call me Boruto." Boruto scratched his head, smiling.

"I'm Sazu." Future Sasuke said calmly.

"Boruto, Sazu, I'm Uzumaki Naruto, just call me Little Big Brother Naruto. Let's help each other out. Since you're Big Brother Naruto's fans and came here, join our training. Training with Big Brother Naruto will surely boost your martial arts skills." Ninja World Naruto said cheerfully.

'Martial arts, martial arts, they keep saying martial arts—what even is that?' Boruto and Sasuke wondered.

They didn't ask, just nodded.

"Hahaha! Great! This grows our team. Next time sparring with that smug Sasuke, I won't lose!" Ninja World Naruto laughed heartily.

His words made Boruto glance at Future Sasuke.

'Was Uncle Sasuke that smug back then?'

Sasuke's single eye showed slight embarrassment, mixed with nostalgia and warmth.

No mistake—this idiot was the Naruto he remembered.

Smug Sasuke, a nickname that stirred fond memories.

"Alright, enough chit-chat. Let's train properly! Feel my muscle power closely! Remember to activate Breathing Style, mind the rhythm." Imperial Naruto shouted, striking another dizzying pose, radiating golden light.

Boruto and Future Sasuke were shocked, fearing loss of control.

Luckily, Imperial Naruto held back; they felt no oddity.

Ninja World folks under the light had pulsing muscles, closing their eyes, breathing slowly.

With their breaths, Boruto and Future Sasuke saw Ninja World Naruto enveloped in emerald-green wind, swaying, lifting his clothes' edges, blonde hair fluttering, giving him an indescribable lightness.

Hinata and Neji were cloaked in fine lightning arcs.

Chouji and Kiba's skin, originally flesh-toned, turned grayish-brown, stone-like.

Seeing this, Boruto and Future Sasuke were stunned.

Boruto cautiously glanced at Future Sasuke. "What jutsu is this? Does… Uncle Sazu know?"

"Likely a jutsu akin to Lightning Chakra Mode." Future Sasuke whispered, avoiding too much detail to not leak information.

But this world's Naruto—wasn't training Sage Mode? Or Kyuubi Chakra Mode?

"Lightning Chakra Mode? The Raikage's jutsu? I heard it's a powerful taijutsu, greatly enhancing body functions. Didn't expect them all to master similar jutsu… incredible." Boruto observed intently.

Ninja World Naruto's aura shifted.

The wind around him spun continuously, forming a vortex. Orange glints appeared at his eye corners, natural energy filling him.

Then, something astonishing happened.

Around Ninja World Naruto, Rasengans formed on their own, orbiting him.

He looked majestic, like a wind god.

"That's Rasengan! So many Rasengans! What jutsu is this? So cool!" Boruto shouted, shocked.

"Indeed impressive. This is Little Naruto's self-developed Sage Wind Mode, blending Sage power with advanced Wind Breathing Style, automatically absorbing natural energy for endurance while auto-releasing ninjutsu." Imperial Naruto explained. "Rasengan is Little Naruto's signature jutsu, so it's auto-released. But he aims to shift the auto-released ninjutsu from Rasengan to Rasenshuriken, a much harder step."

"S-so cool… auto-releasing A-rank ninjutsu like Rasengan." Boruto's eyes widened.

"Quite strong…" Future Sasuke nodded, but that was all.

Rasengan was strong? Decent, but without Kyuubi chakra, it wasn't enough!

Urashiki couldn't be fought with such power.

But auto-releasing Rasenshuriken would aid greatly against Urashiki—sadly, not enough.

"What're… Sister Hinata and Brother Neji training?" Boruto asked.

"They're training a mix of Lightning Breathing Style and Gentle Fist… watch closely! They're moving!" Imperial Naruto said.

Hinata and Neji, eyes closed before, moved.

Eyes open, their fingers pointed at distant trees.

*BAM!* *BAM!* *BAM!* *BAM!*

Lightning-element energy balls shot out, striking a large tree.

*BAM!* *BAM!* *BAM!* *BAM!*

After small explosions, the tree's surface wasn't badly damaged, but as Hinata and Neji withdrew, its bark peeled, lush leaves withered, falling. The tree died in seconds.

"S-so strong… what's this?" Boruto asked.

"Humans have acupuncture points; trees do too. Pressing human points causes symptoms; same with trees. Hinata and Neji use trees as human substitutes. This tree's kill point was struck, so it died." Imperial Naruto explained.

"Striking acupuncture points from afar, controlling lightning energy—nice move." Future Sasuke commented.

Compared to his world, this world's Hinata and Neji were far superior, earning his praise.

"What about Brother Kiba, Brother Chouji…" Boruto asked.

As he spoke, grayish-brown Kiba roared: "Stone Breathing: Unbreakable Vajra—Piercing Fang!"

"Guk!"

With a dog's bark, two Kibas became grayish-brown tornados, rampaging across the ground.

Soil, rocks, trees—all shattered under Piercing Fang.

"Stone Breathing: Partial Vajra Multiplication!"

Chouji roared.

His right fist swelled, turning steel-like, slamming forward.

The ground crumbled like tofu.

The shockwave sent Boruto flying. Agile, he stabilized, landing on a tree, shielding himself, staring at the tens-of-meters-wide crater from Chouji's punch, stunned. "So strong… this punch is even stronger than Granny Tsunade's Super Strength Punch. They're all so powerful! This might make facing that guy much easier."

Boruto smiled unconsciously.

"Decent, but far from enough against that guy. He's not an opponent regular ninja can face. Drop your naivety, Boruto." Future Sasuke whispered, appearing beside him.

His assessment: this world's Chouji, Kiba, Hinata, and Neji were Kage-level, but useless.

Kage-level? Before Otsutsuki, no different from ants!

Rasengans around Ninja World Naruto spun fiercer, wind chakra pouring in, forming serrated edges, the surrounding storm intensifying.

"Go! Rasenshuriken! Did Big Brother Naruto succeed!?" Boruto exclaimed.

"Not that simple." Imperial Naruto shook his head.

Indeed, Ninja World Naruto's Rasengans burst like bubbles. He opened his eyes, slightly frustrated. "Failed again… Big Brother Naruto, do you think I can really succeed this way?"

"You're on your own path now. Believe in yourself, Little Naruto. The martial arts path is never smooth." Imperial Naruto consoled, patting his shoulder.

Ninja World Naruto pursed his lips, resuming training.

Boruto and Future Sasuke watched the group train until nightfall.

As they parted, Ninja World Naruto waved, about to leave.

Boruto suddenly panicked, rushing to his side. "Wait! Wait! Little Big Brother Naruto, wait!"

"What's up, Boruto?" Ninja World Naruto asked gently.

"Uh…" Boruto hesitated, glancing at Imperial Naruto.

Imperial Naruto frowned, recalling their earlier words.

Protecting Naruto… did they mean Little Naruto? That made sense.

"Little Naruto, Boruto and Sazu are from a mountain village, visiting the Empire, and haven't found a place to stay. Take them to your house for now." Imperial Naruto said.

"Stay at my place? No problem." Ninja World Naruto agreed without much thought.

He ruffled Boruto's head casually. "Let's go, Boruto… for some reason, I want to spend more time with you."

Ninja World Naruto led Boruto and Sasuke away.

Hinata, Neji, and the others didn't think much of it.

This was the Empire!

They'd lived here for one and a half years, free of danger, with warm, positive daily life.

Ninja world deceit and schemes were long gone.

So, they had no ill thoughts toward Boruto and Future Sasuke.

Even ninja world remnants were mostly irrelevant, lacking deep martial arts support, too weak to notice.

Neji, Chouji, and Kiba left.

Hinata gazed at Naruto and Boruto's backs, lingering before reluctantly leaving.

Lastly, Imperial Naruto crossed his arms. "Is this about Little Naruto? Could more ninja world folks have come to the Empire via Ryumyaku? Impressive they can still get here… but my muscles sense no hostility, so I'll trust them a bit. Brother… watch them closely."

As his words fell, wooden branches detached from his burly body, forming another Imperial Naruto.

This clone patted his muscular belly, grinning brightly. "Leave it to me, main body! I'll protect Little Naruto well—no one can threaten my target!"

He headed toward Ninja World Naruto.

Leading Boruto and Sasuke, Ninja World Naruto returned home, opening a large iron gate.

Seeing artificial rocks, a spring, a lawn, and fruit trees around, Boruto said, "Little Big Brother Naruto… this is your house?"

"Yup! My house. Pretty nice, right?" Ninja World Naruto grinned widely.

"Not just nice, it's amazing! Like a mansion only rich folks like Denki could live in—awesome!" Boruto recalled his home.

Though his dad was Hokage, they lived in an apartment!

Sasuke also took a breath.

Once, he was the wealthy Uchiha young master, owning vast lands and lavish homes.

Middle-aged now… his wife, Haruno Sakura, lived in an apartment, still paying off a house!

This world's Naruto, so rich? How? Robbing daimyo? Or tycoons?

"Hahaha! A rich man's house? Something like that… my clones can work a hundred jobs a day, Dad's deputy security chief, Mom's flower shop has dozens of branches—it's all small stuff!" Ninja World Naruto bragged, thumbing his nose proudly.

"Wait… Dad, Mom, Little Big Brother Naruto's parents?" Boruto caught a blind spot, his face incredulous.

Future Sasuke felt the same.

Were they revived via Edo Tensei, staying with Naruto?

Doing that wasn't too disrespectful to the dead?

Future Sasuke frowned, displeased.

"Of course." Ninja World Naruto smiled happily.

One and a half years in the Empire with his parents were his happiest times.

He didn't explain much, leading them along the path.

At the door, turning the knob, a gentle voice sounded: "Master, welcome back."
