"No… I can't hold back any longer."
"Susanoo!"
Realizing that his father had unleashed terrifying power far beyond his expectations, Senba knew he could no longer afford to hesitate.
His Mangekyō Sharingan spun rapidly.
In an instant, a fifty-meter-tall, legless, incomplete Susanoo materialized around him.
Wrapped within the giant spectral warrior, Senba charged straight at Isamu.
"So…"
"Now we're getting somewhere."
Watching Senba finally call upon the true power of the Uchiha Clan, Isamu smiled.
The black-and-white energy surrounding him continued to gather.
His preparations were complete.
By combining attraction and repulsion, he altered the very nature of space itself.
Gravity was born from the union of Ultimate Yin and Ultimate Yang.
Isamu clasped his hands together.
"Sage Art: Yin–Yang Release—Gravitational Crush!"
An invisible force descended upon Senba.
It was as though an entire mountain had been dropped onto his shoulders.
The overwhelming gravity continuously compressed his Susanoo.
The charging giant stopped dead in its tracks.
Its knees buckled.
Senba was forced into a half-kneeling position, pain spreading across his face.
"This pressure…"
"It feels like an entire mountain is crushing me…"
His eyes widened in disbelief.
He had never witnessed this kind of power from his father before.
"Mother…"
"What's happening to Father?"
Watching from high above, Itachi looked on in confusion as Senba was suddenly forced to his knees.
"I don't know exactly what technique he's using…"
"But it's obviously your grandfather's doing."
Mikoto looked toward Isamu's clasped hands.
It was clear that this mysterious force originated from him.
"…Father…"
Itachi clenched his fists anxiously.
He couldn't stop worrying.
Looking at Senba, who had been subdued almost instantly, Isamu wasn't pleased.
Instead…
He frowned.
This manipulation of gravity was merely one of the most basic applications of Ultimate Yin–Yang Release.
The fact that such a simple technique had already suppressed Senba disappointed him.
Walking until he stood only five meters away, Isamu spoke coldly.
"What?"
"You can't even endure ten percent of my strength?"
"Your power should amount to far more than this."
"Show me what you're really capable of."
"Damn it…"
"I'll earn your approval today!"
Grinding his teeth, Senba struggled to rise.
"How disappointing."
"To think that my son possesses only this much ability."
"My approval isn't won through empty words."
"Show me your strength."
"Stop dreaming."
Seeing that Senba's chakra still wasn't increasing, Isamu's disappointment deepened.
His hands tightened.
"Gravity Increase!"
The pressure multiplied.
Crack…
Cracks slowly spread across Senba's Susanoo.
It was beginning to collapse.
"I…"
"I can't fall here…"
"I have to prove to Father…"
"…that I haven't disgraced him!"
Senba clenched both fists.
His Mangekyō spun faster than ever before.
"AAAAAHHHHH!!"
An ocean of pale-blue chakra exploded from his body.
Immense ocular power erupted at the same time.
With a deafening roar…
He shattered the gravitational restraints.
Boom!!
A colossal Complete Body Susanoo, nearly eight hundred meters tall, rose into the sky.
Senba floated within the crystal at its forehead.
"This…"
Itachi stared upward in complete shock.
He had seen Susanoo before.
But never one this enormous.
"This…"
"…is your father's Complete Body Susanoo."
"And it's his strongest technique."
Mikoto looked proudly at the towering warrior.
It represented the pinnacle of the Uchiha Clan's power.
"Complete Body Susanoo?"
"How is it different from ordinary Susanoo?"
Itachi asked curiously.
"It's difficult to explain."
"I've heard there are extremely strict requirements for awakening it."
"You'll have to ask your father about the details someday."
"But one thing I can tell you…"
"…is that in the entire Ninja World, only two people can use Complete Body Susanoo."
"Two?"
"Besides Father…"
"…who's the other one?"
Mikoto smiled.
"Your grandfather."
"Uchiha Tensei."
"After your great-grandfather Madara passed away, your grandfather became the only other person capable of using Complete Body Susanoo."
"In fact…"
"Almost everything your father knows—his techniques, his abilities, even many of his jutsu…"
"…were inherited from him."
"It's Grandfather?"
"That's incredible!"
Itachi couldn't help staring at Isamu with newfound admiration.
He hadn't expected his father's greatest power to have come directly from his grandfather.
"Oh…"
"So this is your Complete Body Susanoo."
Isamu narrowed his eyes.
Eight hundred meters.
That appeared to be Senba's current limit.
Although it still fell short of Isamu's own thousand-meter Susanoo, such power was already enough to dominate almost anyone in the Ninja World.
He nodded with satisfaction.
At least Senba had reached this level.
"Father."
"This is the same technique you once demonstrated before me."
"I wonder…"
"…can you still break it?"
Standing within his towering Susanoo, Senba looked down confidently.
He believed that even his father wouldn't be able to destroy it easily.
Seeing that smug expression, Isamu sighed helplessly.
"If this were used against anyone else in the Ninja World…"
"…it would indeed be nearly invincible."
"But against someone who has surpassed the Six Paths…"
"…breaking it is far too easy."
After all…
No one understood Complete Body Susanoo better than he did.
"You're still just as arrogant."
"No matter how many years pass…"
"…that habit never changes."
"Today…"
"…your father will teach you one final lesson."
"The lesson is called…"
"Humility."
As he spoke, Isamu slowly rose into the air.
Golden chakra enveloped his body.
He entered Six Paths Sage Mode.
Twelve Truth-Seeking Orbs floated silently behind him.
The overwhelming pressure of Six Paths Power crashed toward Senba.
In an instant…
Senba felt as though he had fallen into an endless frozen abyss.
Death itself seemed to wrap around him.
Neither Mikoto nor Itachi dared blink.
They both knew…
Isamu was finally about to reveal his true strength.
With one smooth motion, Isamu drew the Kusanagi-no-Tsurugi.
Gripping it tightly, he slowly raised it overhead.
"Embrace killing intent…"
"…and pierce the dawn."
"Kusanagi-no-Tsurugi—Sword of Heaven and Earth!"
The divine blade expanded instantly.
Eight hundred meters.
Unlike the technique inherited from Indra, this version no longer required Susanoo.
Using his own body to withstand the unimaginable strain…
Isamu had perfected the ultimate form of the technique.
A sword capable of cutting through anything.
"This…!!"
Senba's pupils shrank.
Without hesitation, he drew the two three-hundred-meter swords from his Complete Body Susanoo.
He crossed them before himself, preparing to block the incoming strike.
"Senba."
"Watch carefully."
"This…"
"…is how your father destroys a Susanoo."
With those words…
Isamu swung the Kusanagi-no-Tsurugi downward.
