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

Chapter 145: Kaido Questions His Existence



Haruki could see his opponent's strength. If this high-intensity fight continued, he estimated he'd lose in less than half an hour.

That too, only if his opponent didn't understand ninjutsu.

This time, someone from World Number 3 was this strong?

King narrowed his eyes, his expression serious.

(This kid… his strength seems slightly above mine, and his abilities are too bizarre and varied.)

Imperial Naruto, watching, blinked, gaining a more intuitive understanding of Kaido's power.

"Naruto, how strong is this cheeky kid in your world?" Kaido asked, his expression somewhat serious.

Being outdone by a kid and failing to beat him still irked him.

"Haruki? He's a genius here. At 13, he had Kage-level strength. After the world fusion, he progressed rapidly, then gained Haki. Though he can't train Conqueror's Haki, his Armament and Observation Haki are at a very high level. In the entire Empire now, his strength is top-tier—few surpass him." Imperial Naruto explained.

"I see." Kaido nodded, feeling slightly relieved.

"Hehehe… I'm a Hatake Clan heir, after all. If I were weak, I'd disappoint my father and grandfather's teachings." Haruki said proudly.

"Yo! Everyone's here! Wow! What's this? A dragon? A huge dragon—looks so cool!"

A spirited shout came from nearby.

Kaido turned to see a blonde boy, strikingly similar to Imperial Naruto, waving as he approached.

"Eh… is this Naruto's little brother?" Kaido asked.

"Hahaha… Little brother? You could say that." Imperial Naruto laughed, not elaborating.

Ninja World Naruto saw Kaido's dragon form. "Wow, it talks too. Must be a Devil Fruit user from another world? So cool."

"Hahaha… Cool? How about joining my world? I can give you an awesome Devil Fruit." Kaido's old habit resurfaced.

"No need. I'm comfy in my world." Ninja World Naruto shook his head, then added, "Haruki, Shishui, and Big Bro Naruto, perfect timing. Sasuke challenged me to a duel again. I think we need someone to reinforce the barrier."

"Big Bro Sasuke again? His fighting spirit's intense." Haruki complained.

"It's their bond, like Big Bro Naruto and Big Bro Sasuke." Shishui said.

"Kaido, wanna watch? It'll be a fight between our Empire's true fighters." Imperial Naruto offered.

"True fighters?" Kaido's eyes lit up. "Who's stronger, him or Naruto?"

"Of course Big Bro Naruto's stronger! I'm far behind him." Ninja World Naruto said without hesitation.

"I'm slightly stronger, but Little Naruto and I aren't too far apart now. His strength ranks in the Empire's top ten." Imperial Naruto said humbly.

"Top ten? Sounds really strong. What about you, Naruto? What's your rank?" Kaido was intrigued.

"Me? Probably top five." Imperial Naruto thought briefly.

"Top five, huh… Didn't expect this world to have four others who can match a fighter as strong as Naruto? I really wanna see them." Kaido sighed.

Naruto defeated him with one blow—Kaido couldn't fathom Imperial Naruto's upper limit.

(But a god-like figure like this, and this world has five? Truly… this world's people are far stronger than us.)

"Come, let's watch Little Naruto and Little Sasuke's fight." Imperial Naruto led Kaido and King, following Ninja World Naruto through corridors to a massive metal room, over six or seven kilometers in length, width, and height.

In the room's center, a black-haired man with strange purple-glowing eyes, pupils formed of concentric circles, turned his gaze.

Instantly, Kaido's body trembled, feeling immense pressure and hostility.

This guy's strong—far stronger than me!

And his aura's so unfriendly!

(This is who'll fight Naruto's little brother? Maybe one of this world's top ten fighters? Come on! Show me how much power you can unleash at full strength!) Kaido's eyes showed anticipation.

"You finally showed up. Taking so long just to get barrier reinforcements, you loser." Ninja World Sasuke, arms crossed, mocked Ninja World Naruto.

"What can I do? I meant to find Big Sis Hinata and Big Bro Neji, but they didn't come to train today, so I had to find others. Luckily, I found Big Bro Naruto, Shishui, and Haruki." Ninja World Naruto scratched his head.

"Hmph… That big guy over there, from another world?" Ninja World Sasuke glanced at Kaido.

"Yup! This uncle's from another world, ate a Devil Fruit, and can turn into a huge dragon—super cool!" Ninja World Naruto said excitedly, gesturing, his eyes twinkling like stars.

"Huge dragon? How huge?" Ninja World Sasuke raised an eyebrow.

Bigger than Big Bro Naruto's wooden dragon? Thousands of meters long?

Ninja World Sasuke eyed Kaido more seriously.

Sensing the gaze, Kaido instinctively straightened, as if regaining his dignity as a strong fighter in this world.

It lifted his spirits slightly.

"Uh… maybe over a hundred meters long!" Ninja World Naruto thought and answered.

"Over a hundred meters? Isn't that an eel? What's cool about that?" Ninja World Sasuke's face changed.

"E-eel?" Kaido's aura collapsed, his eyelids twitching.

King's face behind his mask sweated.

Normally, if Kaido heard someone describe him like that, he'd swing his club.

But after roughly grasping this world's fighters' strength, he forced himself to restrain, saying with a flushed face, "Over a hundred meters, and you call it an eel? Could this little brother get even bigger?"

"You think I can't?" Ninja World Sasuke retorted.

"Hey, hey, hey… Don't talk like that, Sasuke… It's really cool, and a hundred meters is super long and big!" Ninja World Naruto shouted.

"Hmph! Whatever, I'm done talking. Let's fight—I can't wait to beat you." Ninja World Sasuke urged.

"Alright, let's do this! Vajra Formation!" Imperial Naruto nodded beside them, clasping his palms.

Haruki and Shishui did the same.

Instantly, their chakra and True Qi erupted, spreading rapidly, forming a golden light that coated the metal walls.

"Oh? It can work like that? Like the Bari Bari no Mi—such a practical, versatile ability…" Kaido said, slightly envious.

He then turned to Ninja World Sasuke, who'd talked big, eager to see how huge his monster would be!

Sensing Kaido's gaze, Ninja World Sasuke didn't hesitate.

Terrifying chakra and True Qi erupted, condensing into a giant that kept growing—ten meters… fifty… a hundred… three hundred… six hundred meters, clad in armor with four arms.

Seeing this giant, Kaido's eyes widened, his face stiffening.

King beside him gasped. "This kid's incredible… no wonder he talks so big."

"Compared to this guy, my dragon form's just an eel… but a big body doesn't mean strength; it can be clumsy. Like this, he might struggle against Little Naruto…" Kaido said.

Just then, Ninja World Sasuke's 600-meter Susano'o sprouted a katana in each of its four hands, slashing left and right!

*BOOM!!!!*

Four thousand-meter wind blades tore through the air, slashing toward Ninja World Naruto.

Ninja World Naruto's figure darted and vanished.

The wind blades hit the barrier coating the metal walls.

The room trembled slightly. But this minor tremor made Kaido's expression shift again.

When he faced Hatake Haruki earlier, his attacks barely shook the walls without a barrier, the tremor negligible compared to now.

Now, with the barrier, the room's impact resistance far exceeded the previous one.

Yet it produced a similar, even stronger effect?

So, the 600-meter giant's attack intensity was how many times stronger than his? Twice? Thrice? Four or five times?

This world's strong fighters were truly monsters among monsters!

"Sasuke! Take this! Sage Art: Shinra: Great Rasengan!" A shout came from above.

Kaido looked up. Ninja World Naruto, who'd vanished, appeared above Ninja World Sasuke's 600-meter Susano'o, raising his right hand high. A 200-meter green Rasengan shot toward Ninja World Sasuke!

"Naruto! To beat me, this level's far from enough! Sage Art: Shinra: Amaterasu Kagutsuchi!" Ninja World Sasuke roared.

Susano'o's four hands converged, forming a hundreds-meter-long black flame arrow that shot toward Naruto in the sky.

Rasengan and arrow collided.

Fierce winds and flames nearly filled the entire barrier.

The barrier trembled incessantly, rumbling nonstop.

Kaido and King outside, watching, shifted from shock to numbness.

They guessed the attack intensity of the two inside could destroy all of Wano Country…

Such intense attacks, launched so casually?

How could these people be human?

The fight inside the barrier lasted over three hours.

Finally, Ninja World Sasuke and Naruto exhausted their energy, collapsing unconscious.

Imperial Naruto smiled, asking Haruki and Shishui to carry them away.

He then continued walking with Kaido and King. Soon, they passed another room where a blonde woman and a white-haired man fought.

The blonde woman moved incredibly fast, while the white-haired man used bizarre abilities, his body erratic, spewing fire, water, lightning, even mud, and more.

Even when these harmed the woman, her body healed instantly.

To Kaido and King, these two were stronger than the earlier kids, their power nearing Kaido's own…

Likely on par with the Third Raikage.

Why were there so many strong fighters in this world?

"Naruto, didn't you say those two kids were already strong fighters here? Why does everyone we meet seem stronger?" Kaido questioned his existence.

"Huh? No, no, you must've seen Grandma Tsunade and Grandpa Jiraiya's duel, right? They're also top-tier Empire fighters, and older, so it's natural they're stronger than Haruki and Shishui." Imperial Naruto explained.

"Even so, don't the Empire's strong fighters have anything better to do? Why are so many here, and we just happen to see them?" King suspected this was the Empire intimidating them.

Deliberate!

"Hm? That? To face the Otsutsuki, His Majesty ordered everyone to train hard, dueling at least twice weekly with opponents of similar strength."

"To promote dueling spirit, His Majesty even developed the Empire's Martial Ladder Ranking… Though I think it's not great, many take it seriously." Imperial Naruto explained.

"Oh, I see. Your nation values training and strength growth—admirable. But what's the Empire's Martial Ladder Ranking?" King asked.

"The Empire's Martial Ladder Ranking lists all Empire fighters, who duel each other. Winners gain points, losers lose them, ranking the strongest fighters." Imperial Naruto said briefly.

"There's such a thing? Doesn't that make everyone's strength clear? Why did you describe your and your brother's strength so vaguely earlier?" Kaido asked.

"Though the ladder's great, equally strong fighters often beat each other, and frequent dueling can slightly skew rankings…" Imperial Naruto explained.

"Worororo… Got it. Still, we're curious. Naruto, can you show us this Martial Ladder Ranking?" Kaido laughed heartily.

"Of course. Take a look." Imperial Naruto smiled, nodding, pressing his watch. A beam projected upward, displaying large text in the air.

Kaido and King couldn't read it, but it soon shifted, becoming understandable.
