Nagato: Isn't it just Complete Body Susanoo?

In Amegakure.

Uchiha Ruri stood within the forehead of the Fourth Form Susanoo, as if she had merged into one with this massive energy construct.

Ruri's figure flickered within the forehead of the Susanoo; her presence seemed to infuse even more power into this already formidable entity.

In this instant, Ruri and the Susanoo seemed to have become a single entity, their powers intermingling and amplifying one another.

A giant several dozen meters tall suddenly appeared in the peaceful village, causing the panicked villagers to flee in every direction, terrified of dying there.

"Hiding and refusing to come out, are we? Then I'll force you out." A cold sneer curled the corners of Ruri's mouth, and a sharp, icy glint flashed in her eyes, as if she could peer into every hidden corner.

She knew that Pain was lurking in the shadows, revealing not a single flaw, but that would not stop her from flushing him out.

At this moment, she decided to use this immense power to force that cunning coward out of his hiding place.

With a thought from Ruri, the Susanoo instantly solidified, its massive body standing as towering as a mountain, radiating a suffocating pressure.

She extended both hands, and two enormous blades appeared in the Susanoo's grip, their edges sharp and gleaming with a cold light, as if they could cleave through anything.

Ruri aimed toward the direction of Amegakure, where her target lay.

She knew that the members of Akatsuki were hiding in some corner of that village, watching her every move.

Without hesitation, Ruri gripped the hilts tightly and swung forward with a violent force; two fierce slashes of blade energy instantly tore through the sky, hurtling toward Amegakure.

The blade energy carried the power of all the Tailed Beasts, sweeping through everything like two violent tornadoes.

The trees and houses along the path appeared so fragile before this overwhelming power, instantly pulverized into dust.

The villagers of Amegakure were thrown into a panic by this sudden disaster, fleeing in all directions. However, the blade energy moved too fast; they had no time to react before being ruthlessly swept up in its wake.

Ruri did not stop her movements, continuously brandishing the twin blades and hacking wave after wave of energy toward Amegakure.

The entire village seemed shrouded in a storm of blades, filled with shattered buildings and terrified screams.

Six Paths Sasuke already possessed a wealth of combat experience. After receiving Sasuke's memories, the system's artificial intelligence provided some assistance, separating their respective ideologies to keep Ruri clear-headed. Absorbing the memories was mostly a matter of relying on herself, drawing upon the combat experience extracted from Sasuke's memories.

After Uchiha Ruri ceased her attack, the ruined houses of Amegakure looked just like Konoha after the assault by Pain in the original story.

"An incredible enemy has arrived. Itachi, is that a member of your family?" Kisame Hoshigaki's tone held a hint of shock, yet he maintained a rare calmness.

His gaze remained fixed on the massive figure approaching from afar—the Susanoo controlled by Ruri—and the powerful aura it radiated made one feel an involuntary sense of awe.

Itachi Uchiha stood beside Kisame, his eyes already activated as the Mangekyo Sharingan, his deep pupils seemingly containing the mysteries of an infinite universe.

He stared at Ruri's Susanoo, feeling the powerful aura rushing toward him, and a ripple stirred within his heart.

"This is the Susanoo of your clan, isn't it? This immense power is truly terrifying," Kisame remarked again.

As an experienced ninja, he had seen countless powerful enemies and ninjutsu, but this was the first time he had witnessed someone capable of controlling a Susanoo to such a realm as Ruri.

Itachi did not answer Kisame's words, his gaze locked firmly on Ruri's Susanoo.

He knew this battle would be the most difficult of his life. Ruri's Susanoo had already evolved to the fourth stage, and its power surpassed anything Itachi could have imagined.

Ruri's Susanoo slowly drew closer, each step feeling as if it were landing on everyone's hearts. Its massive frame was like a mountain, inspiring dread.

The powerful aura radiating from it made the surrounding air feel as if it had solidified.

"My clansmen have all been dealt with by me, but I have never seen this person before, and her strength is greater than mine," Itachi finally spoke, his voice low, as if recounting a past he could not bear to look back upon.

He knew a battle between himself and Ruri was inevitable, but he did not regret his choices.

He had already begun to regret joining Akatsuki; he had just met a new member, and now a strange clansman had appeared? The key was that she was incredibly powerful.

"Itachi, what should we do?" Kisame asked with some concern. His voice echoed in the air, carrying a hint of helplessness and confusion.

He knew that although he and Itachi were both powerful ninjas, they likely had little chance of winning against an enemy like Ruri.

Ruri's Susanoo stood before them like a mountain, its massive size and immense power giving them a sense of pressure they had never felt before.

Itachi did not answer Kisame's question immediately, his gaze still locked on Ruri's Susanoo.

"We fight," Itachi said calmly. His voice was steady, yet filled with determination and resolve.

He knew this battle would be the hardest of their lives, but they would never back down.

Just then, Konan, Pain, and Juzo Biwa walked over. Their appearance surprised Itachi and Kisame, but also brought a glimmer of hope.

"Itachi, Kisame, are you alright?" Konan asked with concern. Her gaze swept over them, and seeing they were uninjured, she breathed a sigh of relief.

She knew that facing an enemy like Ruri, the slightest carelessness could lead to injury or even death.

"We are fine," Itachi replied. He turned his gaze toward Pain and gave a slight nod.

He knew Pain was a reliable partner, and his joining would make this battle more hopeful.

Pain did not speak, merely nodding in response. His gaze lingered on Ruri's Susanoo for a moment before turning to Itachi and Kisame.

"You two stand back. I will go and meet this new friend first. Even if she possesses great strength, it is futile before a god," Pain said arrogantly.
