One Piece: Kaido's adopted son, starts with the Eight Gates Formation.

The aged voice, like a thunderclap, resounded in the hearts of all those facing death!

Almost at the same moment he finished speaking.

Sizzle—!!!

The eternally unchanging pure white sky of Seireitei was forcibly torn open from the outside by an extremely savage force, creating a huge black rift!

Followed by.

A massive, sky-covering island slowly emerged from the crack, casting its shadow over the entire Seireitei!

At the edge of the island, a burly figure with two horns on his head and wielding a spiked club was looking down at the Grim Reapers below, who were on high alert.

He grinned and let out a wild, unrestrained laugh that shook the entire Soul Society!

"Gurarararararar! Is this the new world?"

"Looks like there's plenty of 'good wine' that will let me have a good drink!"

Sizzle—!!!

That pitch-black rift, like a hideous scar torn open on a pure white canvas, completely cleaved the sky above the entire Seireitei.

Immediately afterwards, a floating island so vast that it could not be measured by sight slowly emerged from the deep chaos, revealing its full form.

The war fortress, made of metal and rock, blocked out the sun.

Several enormous engines, as dazzling as the sun, spewed out breathtaking energy, suspending the entire island steadily above Seireitei.

"What...what the hell is that?!"

An ordinary soldier, head tilted back, his Zanpakuto trembling violently with extreme fear, was unable to even form a complete sentence.

That's not spiritual pressure.

That's not an illusion.

It was a pure, savage, physically tangible... oppression!

It was as if the entire sky had collapsed!

What froze their souls even more were the several enormous, god-like figures standing on the edge of the island.

A burly giant with two horns on his head, wielding a spiked club.

An elderly man with a white beard, several times the size of the former, resembling a small mountain, wielding a naginata.

There was also a fat woman riding on a thundercloud, emitting a sharp, maniacal laugh.

Their very existence distorted the surrounding space. Their domineering and unreasonable aura, like billions of tons of seawater, pressed down hard on the shoulders of every Grim Reaper, making it incredibly difficult for them to even breathe.

The Seireitei, the city of death that has stood for a thousand years, fell into an unprecedented silence at this moment.

Just then.

"What kind of scoundrel are you!"

A hoarse yet infinitely majestic roar resounded like thunder in the hearts of all those facing death!

A figure appeared instantly at the forefront of all the Grim Reapers.

It was none other than Yamamoto Genryusai Shigekuni, the Captain-Commander of the Gotei 13!

He held that seemingly ordinary wooden cane, yet his short stature unleashed a terrifying spiritual pressure that seemed to scorch the heavens and boil the seas!

The scorching spiritual pressure shot into the sky, transforming into a visible pillar of flames that forcefully pushed back the terrifying pressure descending from the heavens!

The Grim Reapers below immediately felt the pressure ease and revealed expressions of excitement at surviving a near-death experience.

"It's the Captain-Commander!"

"The Captain-General is here!"

In their hearts, as long as this man is still standing here, Seireitei will never fall!

however.

The invaders in the sky clearly did not take the commander-in-chief's authority seriously.

"Guralalalalala!"

Kaido lowered his head, his ferocious dragon eyes looking down at the old man below who looked like an ant, and grinned, letting out a disdainful laugh.

dialogue?

Explanation?

Too much trouble.

He has always had only one set of principles for doing things.

Let's fight first and talk later!

Kaido didn't bother with any words. He suddenly opened his blood-red maw and took a deep breath!

A golden-red divine flame, a fusion of the Eight Gates and the Kaioken Technique at twenty times, gathered wildly in his throat!

Immediately afterwards, a spiral of golden energy, crackling with destructive arcs of electricity, rapidly condensed from the golden-red flames!

"Dragon's Breath - Special Cannon!"

boom--!!!!

An unprecedented ultimate energy cannon, combining the destructive power of dragon's breath with the penetrating power of the Special Beam Cannon, burst forth with a piercing shriek that tore everything apart!

Its target was not Yamamoto Genryusai.

Instead, it is the pure white Penitentiary at the very center of Seireitei, symbolizing the highest judicial authority!

This is the purest, most naked, and most unreasonable provocation!

"Too arrogant!"

Yamamoto Genryusai's aged eyes were instantly filled with icy rage!

The cane in his hand shattered with a crack!

It revealed the ancient Zanpakuto inside, wreathed in endless flames!

Captain-Commander Yamamoto held the sword horizontally in front of his chest, and his aged yet majestic voice resounded throughout the heavens and earth!

"All things, nothingness, will turn to ashes!"

"Ryujin Jakka!!!"

boom--!!!!!!!!

An indescribable, extreme heat erupted, centered on Yamamoto Genryusai!

The air was evaporated in an instant, and the earth was burned into glass!

The entire Seireitei seemed to have turned into a giant furnace!

Facing that golden special cannon that could pierce through the heavens and earth, Captain-Commander Yamamoto's eyes turned cold, and he simply swung his sword forward!

"Slay him with a stroke!"

There were no earth-shattering explosions.

That simple and unadorned slash carried an absolute heat capable of incinerating everything, striking first despite being delayed!

Stab it!

Under the horrified gazes of everyone.

Kaido's [Dragon Breath Special Cannon], powerful enough to flatten an island, was actually cleaved in two neatly by that seemingly ordinary flame!

The energy cannon, cleaved in two, flew past both sides of the Palace of Penance, striking the distant barrier and causing a violent explosion.

The fiery strike, undiminished in its momentum, soared straight into the sky!

The entire sky above the Seireitei was burned to an eternal crimson!

This strike proclaimed to all invaders the absolute power of the strongest Shinigami in Soul Society!

above the sky.

"Oh?"

Kaido watched as his seemingly sure-fire attack was so easily neutralized. Instead of anger, his enormous dragon eyes erupted with an unprecedented, fervent excitement, like that of a hunter seeing his prey!

"This old man... is interesting!!!"

next second.

His massive body leaped directly from the "God-Slaying Island" ten thousand meters in the air!

Boom!

That enormous body, like a real meteorite from outer space, carrying an unparalleled and terrifying aura, crashed down fiercely towards the location of Yamamoto Genryusai below!

"Don't even think about it!"

"Vice-Captain Sasakibe no Nakajiro!"

"Listen to my command!"

With a loud shout, the vice-captain Chojiro Sasakibe, who was behind the captain, along with several other vice-captains who had rushed over, simultaneously released their spiritual pressure!

"Binding Spell Number Eighty-One: Severing the Void!"

Several vice-captain level powerhouses joined forces, and an enormous spiritual particle wall, exuding an aura of absolute defense, instantly formed in mid-air, attempting to block the falling "meteorite"!

however.

They still underestimated just how unreasonable this creature from another world was!

Facing that void barrier that could withstand even a Hollow Cero.

Kaido didn't even change his posture!

He just let out an even more excited, maniacal laugh!

Boom!

The barrier broke through the air the instant it made contact with Kaido's body, which was covered in dragon scales and Armament Haki.

They couldn't even hold on for a second!

Just like fragile glass, it was smashed to pieces by that purest, most savage, and most unreasonable physical force!

"What?!"

Chojiro and the others were horrified beyond anything they had ever seen before!

Seeing this, Yamamoto Genryusai frowned. Without further hesitation, he stepped forward and transformed into a streak of flame, charging head-on towards the falling beast!

"clang--!!!!!"

The blade of Ryujin Jakka clashed head-on with Kaido's spiked club, which was wrapped in Conqueror's Haki and Kaioken energy!

A visible shockwave of destruction, a mixture of flames and lightning, spread out with a deafening roar!

The surrounding buildings, like sandcastles blown away by the wind, instantly turned to dust!

Stab it!

Ryujin Jakka's inextinguishable blade left a long, charred mark on Kaido's dragon scales, but ultimately failed to break through that abnormal defense!

The terrifying force emanating from Kaido's spiked club, infused with the power of the Tremor-Tremor Fruit, sent Captain-Commander Yamamoto flying hundreds of meters backward, his feet carving two deep furrows in the ground!

have equal shares!

This powerful clash ignited the flames of war within everyone!

"Mama mama!"

"This looks like a fun party!"

On the island, BIGMOM let out an excited, shrill laugh.

"Men! All troops, attack!"

"Let them see what a pirate 'party' really looks like!"

With her command!

Edward Newgate, the white-bearded swordsman, descended from the sky wielding the Murakumogiri sword and slammed his fist into the ground!

"Crackling!"

Atmospheric cracking!

The three legions, led by Akainu, Aokiji, and Kizaru, descended from the sky like a flood bursting its banks!

Jhin, Queen, Jack, Charlotte Katakuri...

One after another, the notorious powerful figures of the New World, leading their pirate armies, roared as they charged toward the tranquil white city below!

"Charge!"

"The Gotei 13, never retreat!"

Second Division Captain Soi Fon, Fourth Division Captain Retsu Unohana, Fifth Division Captain... After Aizen's defection, the newly appointed Hirako Shinji, Sixth Division Captain Byakuya Kuchiki...

Each captain, with a solemn expression, released their Shikai!

"Scatter, Senbonzakura!"

"Shoot him, sharpshooter!"

"Bloom, plum blossoms!"

In a short time.

Amidst the clash of swords and the bizarre abilities of Devil Fruits, a thunderous collision ensued!

The light of the Kido intertwined with the physical techniques of the Six Styles of the Navy!

An unprecedented, ultimate battle with completely different power systems erupted in the sky above the Seireitei!

The sky above Seireitei was ripped open by Kaido's [Dragon Breath Special Cannon], which incorporated the power of the Kaioken technique. Terrifying energy shot straight into the sky, staining the clouds with an ominous dark red.

However, this attack, powerful enough to destroy an island, was effortlessly cleaved in two by the gaunt old man below with a flaming sword.

"Oh? This old man is interesting."

At the edge of the God-Slaying Island, Lynn swung his short legs, a straw for an AD calcium milk drink dangling from his mouth, and mumbled his comments. The white-bearded man, Big Mom, and the others beside him also wore solemn expressions. They could sense the pure and explosive energy emanating from the old man below, unlike any opponent they had encountered before.

"Gurarararar... He is indeed a formidable powerhouse." Whitebeard crossed his arms, looking down at Yamamoto Genryusai Shigekuni, who was confronting Kaido, his eyes blazing with fighting spirit. "The powerhouses of this world have certainly not disappointed us."

In the center of the battlefield, Kaido's massive body, descending from the sky, was met head-on by Captain-Commander Yamamoto. A spiked club wreathed in Conqueror's Haki collided violently with a Zanpakuto burning with flames of billions of degrees.

There was no earth-shattering explosion, only a muffled, extremely loud bang.

Centered on the two people, the earth instantly cracked, and the terrifying shockwave turned into a visible white wave of air that swept in all directions!

"It...it blocked it?"

"The Captain-Commander actually blocked that monster's attack head-on!"

The Grim Reapers in the distance gasped in surprise. Looking at the Captain-Commander's not-so-tall back, they seemed to see the unyielding backbone of the Seireitei for a thousand years.

The ground beneath Yamamoto Genryusai Shigekuni's feet had completely turned into a glassy surface. The veins on his sword-wielding arm bulged, and a trickle of blood even oozed from the mouth of his hand. He was equally shocked.

"Such immense power... This is no longer just brute force; each strike carries an unreasonable 'will' to crush everything!"

Captain-Commander Yamamoto could sense that the opponent's power system and spiritual pressure were completely different; it was a more primal and domineering energy that originated from life itself.

"Old man! Your flames are not bad! But they're not hot enough!" Kaido let out a maniacal laugh, his arm muscles bulged again, and a deep red Kaioken aura ignited on his spiked club, causing his power to surge once more!

Captain-Commander Yamamoto's pupils contracted as he was forced back several steps by the immense force, each step leaving a deep crater in the ground.

Just then, the captains of the Gotei 13 finally realized what was happening.

"Team, engage!" Soi Fon commanded, her petite figure transforming into a blur as she hurtled towards the war fortress in the sky. Her target was Kizaru, who appeared to be the fastest.

"Oh? What an impatient girl." Kizaru grinned lewdly, his body transforming into countless specks of light as he easily dodged Soi Fon's attack. "Speed ​​is weight. Have you ever been kicked by light?"

On the other side, the tallest man, with a hideous scar on his face and eyes filled only with pure fighting desire—the captain of the 11th Division, Kenpachi Zaraki—spread his mouth, revealing a smile that chilled everyone to the bone.

His gaze didn't fall on those flashy fellows, but instead bypassed everyone else, fixing fixedly on the white-bearded man holding a naginata, standing silently on the edge of the God-Slaying Island as if he were the center of the world.
