"Hmph! Spare us? You're the ones surrounded now. Uchiha Tensei, prepare yourself! This time, I won't be afraid anymore. I will fully uphold the Ninja Way of the Will of Stone!" Ōnoki snorted coldly, his confidence bolstered by the presence of tens of thousands of Ninja.
"You say that every time, and every time you end up getting beaten. I really don't know where you get the confidence to keep saying it. Since I gave you a chance and you refused it, don't blame me for showing no mercy."
Isamu shook his head speechlessly. He had heard Ōnoki make declarations like this far too many times and no longer had the energy to complain.
His expression shifted as the Eternal Mangekyō Sharingan in his eyes began spinning rapidly. Vast amounts of blue chakra erupted outward, forming a gigantic skeletal structure around him and Senba.
"This is…?" Senba stared at the skeleton in confusion. Having only recently awakened his Mangekyō Sharingan, he had no idea what he was looking at.
"Senba, watch carefully. This is the true power of the Uchiha—the ultimate power!"
As he spoke, Isamu poured more ocular power into the technique. Muscles and armor formed over the skeleton, and a pair of enormous legs emerged, lifting them high into the air.
The Eternal Mangekyō Sharingan's Semi-Complete Susanoo had taken shape.
Looking at the colossal figure towering over a hundred meters tall, memories of the terror he had once experienced at the hands of Susanoo resurfaced in Ōnoki's mind. His face turned pale, and he unconsciously staggered backward. Fortunately, members of his guard unit caught him before he fell.
"Lord Tsuchikage, although the enemy is powerful, we are not weak either. You can't lose your fighting spirit now!" one of the guards said while supporting him.
Even he was terrified by the giant before them, but retreat was no longer an option.
Is this the power of my father, the Asura of the Ninja World?
Looking up at the giant, Senba finally realized just how terrifying his father's strength truly was.
"Keep your eyes open, Senba. This is what true power looks like."
The pentagonal windmill pattern in Isamu's eyes spun even faster.
With the combined output of immense chakra and ocular power, the Susanoo continued to expand. Tengu armor materialized piece by piece, covering its body. A violent gust of wind swept across the battlefield.
Moments later, a five-hundred-meter-tall Complete Body Susanoo stood upon the earth.
Isamu and Senba now stood atop its head.
Senba was speechless.
The scale of the giant before him was beyond anything he had ever imagined.
The guard Ninja supporting Ōnoki no longer had any desire to fight. At that moment, even retreating once or twice didn't seem like such a shameful option.
"Don't lose heart!" Ōnoki shouted desperately. "Maintaining such a massive construct must consume an enormous amount of chakra. As long as we drag this out until he exhausts himself, victory will be ours!"
His words restored a tiny bit of confidence to the Iwagakure forces.
Only a tiny bit.
"Hm? Only five hundred meters?" Isamu frowned. "Is it because my power hasn't fully recovered? Dammit. Not even reaching a thousand meters is rather disappointing."
What do you mean disappointing?!
Senba nearly choked.
A five-hundred-meter giant isn't enough? You wanted a thousand-meter Susanoo? At that point, it would practically pierce the clouds!
"Still, five hundred meters is more than enough to deal with these ants."
The Complete Body Susanoo drew a massive blade over two hundred meters long.
"Ōnoki, try to amuse me. Surpass me. Stop me."
"Today, I'll let you experience the power of the Uchiha once again—a power that was never meant for people like you!"
The gigantic sword came crashing down.
"Not good! Everyone, get out of the way!" Ōnoki shouted.
Unfortunately, a blade over two hundred meters long was not something ordinary Ninja could evade.
The fastest among them barely escaped.
The rest suffered catastrophe.
"AHHH!"
"Help!"
"Run!"
Countless screams filled the battlefield.
The sword strike instantly crushed hundreds of Iwagakure Ninja.
The resulting shockwave killed another hundred.
The destructive force continued outward, splitting a distant mountain cleanly in half.
A peak that had stood for countless years was erased by a casual swing of Isamu's sword.
"S-So powerful…" Senba stared in disbelief.
One slash had annihilated hundreds of Ninja and cleaved a mountain apart.
"Do you understand now, Senba?" Isamu said calmly. "The ultimate power of the Uchiha cannot be overcome through numbers alone. This power is as close to divinity as mortals can comprehend."
The Susanoo drew a second blade.
Dual swords flashed across the battlefield.
Forests vanished.
The ground collapsed.
Each swing claimed four to five hundred lives.
After only thirty seconds of relentless slaughter, nearly half of Iwagakure's main force had been wiped out.
"Uchiha Tensei! Stop!"
Unable to endure any longer, Ōnoki roared in fury.
"Dust Release: Detachment of the Primitive World Technique!"
A cube of blinding light shot forward and struck the Susanoo's sword.
Whoosh!
The two-hundred-meter blade disintegrated instantly.
"Oh?" Isamu raised an eyebrow with interest. "Not bad, Ōnoki."
Seeing the attack succeed, Senba looked at the Tsuchikage differently.
"He completely erased a blade that large. The old man is actually pretty impressive."
"After all, he's the Tsuchikage," Isamu replied. "No one who reaches the position of Kage is weak. Ōnoki's Kekkei Tōta is among the strongest abilities in the entire Ninja World. If he hadn't encountered me, very few people would be capable of dealing with him."
"Kekkei Tōta?" Senba asked curiously.
"A normal Kekkei Genkai combines two chakra natures," Isamu explained. "Kekkei Tōta combines three. Mastering two chakra natures is already beyond most Ninja. Three is far more difficult."
"Anyone struck by that technique will be reduced to particles invisible to the naked eye."
"Even the Uchiha Clan's ultimate defense, Susanoo, can be erased by it."
"A fusion of three chakra natures…" Senba nodded slowly. "That really is terrifying. Father, be careful."
"Ōnoki's Kekkei Tōta is powerful," Isamu admitted. "But he chose the wrong opponent."
"No matter how extraordinary Kekkei Tōta may be, it is still the power of a mortal."
He looked down at the flying Tsuchikage with undisguised disdain.
"Against me—a god walking upon the earth—the outcome of this battle was decided from the very beginning."
With the power of the Sage's Eyes, he possessed countless ways to crush Ōnoki's Dust Release.
