Naruto: Uchiha Izuna with system

"You're done, Tobirama!"

The chilling voice echoed like a death knell, sending shivers down Tobirama's spine. As he twisted mid-air to assess the threat, he saw something that left him momentarily stunned. Izuna, who should have been locked in combat with Hashirama dozens of miles away, had appeared right before him!

Izuna's body was enveloped in the silver-white ribcage of Susanoo. From its left side extended a massive chakra arm gripping a glowing silver-white bayonet.

Whoosh!

With no time to think, Izuna swung the bayonet downward.

Tobirama's instincts screamed at him to react. There was no time to form seals or activate the Flying Thunder God technique.

Whoosh!

Everything had happened too quickly. The entire sequence—from Tobirama's initial attack on the Uchiha's stone wall to Izuna's appearance—had taken less than ten seconds.

It had only been three seconds since Uchiha Yanhuo's kunai was thrown to set up the trap.

This was a battle of Flying Thunder God users, a contest of speed beyond comprehension.

Izuna's left eye spun rapidly, harnessing its Mangekyō Sharingan ability to foresee the next few seconds. It was an ability similar to the future-sight abilities of some warriors in other worlds—a powerful counter against someone like Tobirama.

The battlefield shifted in Izuna's mind. He calculated Tobirama's potential movements based on the five Flying Thunder God kunai scattered around. Which one would he teleport to?

Whoosh!

Tobirama vanished, teleporting to one of the kunai embedded in the mountain wall. But as he reappeared, Izuna's kunai was already flying toward him.

Four seconds had passed.

Tobirama's sharp senses caught the kunai hurtling toward him. His dynamic vision noted the unique markings on the weapon, similar to his own Flying Thunder God seal but with the addition of distinct Uchiha characters.

Whoosh!

Before Tobirama could react further, Izuna materialized right in front of him, still cloaked in Susanoo's ribs.

A grim smile played on Izuna's lips. "I learned this from you, Tobirama—the Flying Thunder God Susanoo Killing Technique!"

Slash!

Susanoo's bayonet came crashing down. Tobirama instinctively raised his Flying Thunder God kunai to block.

Clang!

The blade cleaved through Tobirama's kunai like paper. The next moment, agony tore through Tobirama as the bayonet severed his right arm cleanly at the shoulder.

Seven seconds had passed.

Izuna's left eye glowed ominously. "Amaterasu!"

Fwoosh!

The severed arm ignited mid-air, consumed by black flames before it could even hit the ground.

Tobirama, clutching his shoulder, fell toward the earth below, his body limp and unprepared for the fall.

"Deputy Chief Tobirama!!!"

Senju Yunjian's anguished cry echoed across the battlefield as the Senju forces watched in horror.

"Secret Uzumaki Technique: Sky-Breaking Barrier!"

Several Uzumaki ninjas sprang into action, creating a series of air platforms to cushion Tobirama's fall. They managed to catch him just before he hit the ground, carrying his wounded form to safety.

Back on the wall of the Uchiha stronghold, Izuna teleported using a Flying Thunder God kunai embedded earlier.

Spreading his arms wide, he laughed maniacally. "This is a great victory for our clan!"

"Long live the deputy clan leader!"

The Uchiha forces erupted into cheers, their morale soaring as they witnessed Izuna's incredible feat.

"This is a great victory for Uchiha!"

The morale of the Senju Alliance plummeted.

"You… you also use Flying Thunder God?" Tobirama rasped, his voice trembling with pain and disbelief as he knelt, clutching his shoulder.

From atop the wall, Izuna's voice thundered down. "That's right, Tobirama! Just as you learned the Shadow Clone technique by studying my shadow techniques, I've learned your Flying Thunder God. And unlike you, I've perfected it. Now you know whose Flying Thunder God is superior!"

Tobirama's teeth clenched in frustration. He hated to admit it, but Izuna had indeed surpassed him in using the very technique he had pioneered.

"Attack!" Izuna ordered.

The Uchiha forces, invigorated by their leader's success, unleashed a torrent of powerful jutsu. Fireballs and lightning bolts rained down like a storm, forcing the Senju and Uzumaki forces into a desperate defense.

Izuna descended into the chaos like a ghost, moving with deadly precision. His Sharingan cast illusions, while his mastery of swordplay cut through waves of enemies.

"Protect Tobirama!" Uzumaki Hirokai shouted, rallying the forces to form a defensive line.

Hundreds of Senju and Uzumaki ninjas positioned themselves between Tobirama and Izuna.

"Get out of my way!" Izuna roared, cutting through the opposition with ease. His movements were reminiscent of Madara's during the Fourth Great Ninja War, elegant yet devastating.

Step by step, Izuna closed in on Tobirama. His mind considered unleashing the full power of Susanoo but dismissed the thought. Doing so could destabilize the battlefield and jeopardize their stronghold.
