Naruto: Uchiha Izuna with system

In the original story, members of the Hyuga clan often displayed their signature technique, Kaiten (Revolving Heaven). Mastering this move typically signified reaching the "elite" level of Hyuga.

However, the Kaiten performed by Hyuga Neji or even Hyuga Hizashi only involved forming a defensive chakra sphere around the user.

What Hyuga Tenzong demonstrated now was on a completely different level. If one didn't observe closely, it would be easy to mistake it for Izuna launching a Rasenshuriken.

The impact of Hyuga Tenzong's Kaiten was catastrophic. While Susanoo had already devastated much of the clan leader's mansion, Tenzong's technique caused tremors that shook the ground and obliterated everything within a massive radius.

Senju Hashirama, caught in the aftershock, was sent crashing through multiple buildings in Hyuga's inner city. When he finally landed, he quickly stood up, shaking off debris, and glanced at the distant spinning chakra sphere.

"This… this is insane," Hashirama muttered under his breath.

The Kaiten dissipated, but Tenzong wasted no time switching to offense. A massive Bagua array appeared under his feet, radiating an overwhelming aura.

"Bagua: Shattering Mountain Strike!"

Hyuga Tenzong's palms surged with chakra so intense that it caused the air around him to vibrate audibly.

With a forceful push, he unleashed a torrent of chakra, cascading forward like a tidal wave. Everything in its path disintegrated.

This wasn't just the Shattering Mountain Strike in name—it was the real deal, a technique capable of obliterating actual mountains.

"Wood Release: Ghost Face Technique!"

Reacting swiftly, Hashirama clasped his hands together, summoning a massive grimace-shaped wooden shield.

"Amaterasu Shield!"

Izuna, meanwhile, infused Amaterasu flames into Susanoo's defense, enveloping it in the black flames for added protection.

BOOM!

The impact was earth-shaking. Hashirama's wooden shield shattered, and Susanoo staggered back several dozen meters, leaving both Izuna and Hashirama struggling to maintain their positions.

Meanwhile, some of the retreating ninja clans were caught in the edge of the blast. As they scrambled to safety, they noticed something unsettling—most of the Hyuga, Aburame, and Inuzuka clans had already evacuated Hyuga City before the battle began.

"Damn it!" one ninja cursed. "Those cowards used us as fodder!"

With his Ghost Face Technique crumbling, Hashirama barely managed to catch his breath when Hyuga Tenzong abruptly halted his attack.

Instead of pressing his advantage, Tenzong seemed to mutter to himself, "I know, I know… be quiet! I'll handle it!"

It was a strange sight. To the onlookers, it seemed as though he was arguing with an invisible entity.

"What's going on?" Hashirama whispered, his brow furrowing.

Izuna, standing nearby, ignored the peculiar behavior. His focus remained on the immediate threat.

"Hey, Hashirama," Izuna called out. "This guy's goal is clear. He wants to take us both out so he can dominate the Warring States on his own. We have two choices."

Hashirama turned to him, listening intently.

Izuna continued, his tone sharp, "First, we split up and run. He can only chase one of us, so at least one survives. Or…"

Izuna's lips curled into a faint smirk. "We do something neither of us has ever considered. Uchiha and Senju—unite and fight together."

Hashirama's eyes widened. The mere suggestion was shocking, considering the centuries of conflict between their clans.

"If it were me alone, I'd already be out of here," Izuna added with a sly grin. "But this guy is too dangerous. Even you can't handle him alone, Hashirama."

For a moment, Hashirama hesitated. The thought of cooperating with Uchiha Izuna—a man who had recently maimed his brother Tobirama—was difficult to reconcile.

After several tense seconds, he finally nodded. "You're right. I don't agree with his methods, but the Hyuga clan leader's actions are unjust. For the sake of the ninja world, we must stop him together."

"Spare me the lecture," Izuna muttered under his breath, rolling his eyes. "Let's just kill him already. If I can get him to spill how he got the Tenseigan, great. If not, we end this quickly."

Hashirama clasped his hands together, preparing another wood-style jutsu. Yet, even now, he couldn't resist one last attempt to appeal to reason.

"Hyuga Tenzong!" he shouted. "Why must we fight? With your power, we could end this conflict and bring about peace! We could create a better world for all ninja!"

Tenzong scoffed, his voice dripping with disdain. "Peace? Don't make me laugh. Power is meant to dominate, not to share!"

As if to emphasize his point, chakra erupted from his body, forming a radiant blue aura that resembled flames. The sheer intensity of the energy caused the air around him to distort.

"What… what is that!?" Hashirama gasped, his eyes widening.

The blue chakra cloaking Tenzong bore an eerie resemblance to Naruto's Nine-Tails Chakra Mode. But instead of the warm, protective energy Naruto exuded, Tenzong's aura felt oppressive and suffocating.

"Now this… this is what a real Six Paths level looks like!" Izuna growled through gritted teeth, his expression hardening.

Tenzong vanished in an instant, moving at speeds that even Izuna's Eternal Mangekyō Sharingan could barely track.

Before Izuna could react, Tenzong appeared directly in front of Susanoo, wielding a chakra blade forged from Tenseigan energy.

SLASH!

The blade tore through Susanoo's defenses, slicing it in half at the waist.

Izuna's body, still inside the Susanoo, was caught in the attack. His upper and lower halves separated, blood spraying into the air.

"Izuna!" Hashirama cried out in horror, unable to comprehend how quickly the tide had turned.
