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

Shanks' voice was calm, but to Shunsui Kyoraku, it was like a thunderclap.

"What...did you say?" Kyoraku Shunsui's smile froze. "That's not up to you. Within my 'Katen Kyokotsu' domain, the rules are absolute!"

He could sense that the game's rules had taken effect, and a causal connection based on the "New Demon" rules had been established between him and Shanks. As long as he shouted out a higher number, Shanks would inevitably be harmed; this was an inviolable truth.

"Is that so?" Shanks, still smiling, slowly raised his only remaining left hand.

There was no amazing momentum, no burst of energy.

However, in Kyoraku Shunsui's perception, the world before him suddenly went dark.

An indescribable, terrifying will, seemingly from the ancient past and ruling the world, crashed against his soul like an invisible giant wave!

Om-! ! !

Kyoraku Shunsui's mind went blank for a moment. He felt as if he had become a small boat tossed about in a category 12 tsunami, and could be completely crushed by that terrifying will at any moment!

His spiritual pressure, which he was so proud of and which could make even captains feel troubled, was like a firefly compared to the bright moon in the face of this will—utterly insignificant!

The game realm created by "Katen Kyokotsu" groaned under the impact of this will, and cracks even appeared in the space, as if it would collapse at any moment.

"What...what is this..." Kyoraku Shunsui's body trembled uncontrollably, and cold sweat instantly soaked through his fancy kimono.

He discovered that the connection between himself and his Zanpakuto had been forcibly severed by this will!

The rules of the game are collapsing!

"I told you, your game doesn't work on me."

Shanks' voice rang out again, this time no longer gentle, but with an unquestionable, kingly majesty.

He took a step forward.

"Gods, beware!"

boom!!!

An even more refined and purer Conqueror's Haki than before transformed into an invisible shockwave, striking Kyoraku Shunsui squarely!

Kyoraku Shunsui didn't even have time to react before he felt as if his consciousness had been struck by an invisible giant hammer. His vision went black, and he flew straight backward like a kite with a broken string, crashing heavily to the ground and instantly losing consciousness.

Shanks never drew his sword throughout the entire ordeal.

He used only his purest "will" to completely crush Kyoraku Shunsui, one of the most cunning and unpredictable captains of the Gotei 13.

"Kyoraku!"

On the other side, his friend, Captain Jushiro Ukitake of the 13th Division, saw this scene and cried out in horror. Despite his weak body, he forcibly released his Zanpakuto "Sougo Ritsu" and prepared to go forward to help.

The entire battlefield fell into a brief silence due to Kyoraku Shunsui's sudden defeat.

All the Grim Reapers looked at the red-haired man standing on the edge of the God-Slaying Island with the eyes of someone looking at a monster.

They couldn't understand.

What exactly is that power?

There was no spiritual pressure, no demonic arts, not even the clash of swords; just a glance and a single step were enough to render a renowned captain powerless.

This unreasonable, overwhelming force originating from a higher dimension completely overturned their understanding of combat over thousands of years.

"Domineering...?"

While fiercely battling Kaido, Captain-Commander Yamamoto Genryusai Shigekuni glanced at Shanks out of the corner of his eye. For the first time, a deep sense of apprehension flickered in his cloudy old eyes.

He realized that the power system of these invaders from another world was far more bizarre and powerful than he had imagined.

Conventional fighting methods are probably no longer sufficient to achieve victory.

"It seems... that's the only option..."

Captain-Commander Yamamoto took a deep breath, forced Kaido back with a single strike, and then slowly closed his eyes.

The terrifying heat emanating from him, which seemed capable of incinerating everything, began to converge and recede towards the blade in his hand at an astonishing speed.

The surrounding temperature rose instead of falling, the moisture in the air evaporated instantly, and even space itself began to show signs of distortion.

An aura more dangerous and more despairing than ever before began to slowly emanate from Captain-Commander Yamamoto.

"Um?"

Kaido, who was engaged in a fierce battle with Yamamoto Genryusai Shigekuni, immediately sensed that something was wrong.

He could sense that the old man's aura was undergoing a qualitative change.

The previously explosive and scorching energy, like the sun, is now converging inward at an alarming speed, replaced by a more restrained, purer, and more dangerous aura of destruction.

It's like a volcano that has been accumulating energy for thousands of years, about to erupt in the most thorough and violent way in the next second.

"Oh, hehehehe! Interesting! Old man, are you finally going to show some real skill?"

Instead of being afraid, Kaido became even more excited. His muscles bulged again, and the crimson aura of the Kaioken intertwined with the scarlet steam of the Eight Gates, forming a dark red storm of destruction.

He could sense that the next strike would be the key to victory!

On the island of slaying gods, Lynn, who had been leisurely drinking AD calcium milk, finally put down the bottle in his hand.

He raised his head and looked down at the thin, yet towering old man below. For the first time, a glimmer of "seriousness" flashed in his dark eyes.

"Oh? So it's finally time for Bankai? Zanka no Tachi... this power is quite interesting."

A playful smile, incongruous with his age, appeared on Lynn's small face.

"Father, that old man is about to unleash his ultimate attack, be careful not to get killed by him!" Lynn shouted to Kaido below in a childish voice.

"Hehehehe! Young master, just you wait and see! I am the strongest creature in the world!" Kaido laughed wildly without turning his head, but his eyes were more serious than ever before.

In the Seireitei, all the captains and members who were fighting felt that suffocatingly terrifying aura.

"This spiritual pressure...it's...the Captain-Commander..."

"Could it be... that the Captain-Commander is going to use Bankai?!"

"Back off immediately! Everyone, get away from the captain right now!"

Vice-Captain Chojiro Sasakibe let out a desperate scream, his face filled with terror and awe. He knew better than anyone what a cataclysmic scene the Captain-Commander's Bankai would unleash.

That is not a power that can be used lightly, because its power is enough to turn the entire Soul Society into scorched earth!

Yamamoto Genryusai Shigekuni slowly opened his eyes.

The flames on his "Ryujin Jakka" had vanished, replaced by an ancient katana with charred marks on its blade, resembling burnt charcoal.

However, this seemingly ordinary knife caused the surrounding space to groan in agony, as if it were about to collapse under its weight.

Centered on him, the moisture in the entire Seireitei was evaporating at a visible rate, the earth cracked, buildings spontaneously combusted, and the air was filled with a scorching heat that could dry out even the soul.

"Swastika——"

Yamamoto Genryusai Shigekuni's voice was hoarse yet majestic, like the voice of judgment from ancient times.

"The residual fire sword."

The moment the words fell, the whole world seemed to fall silent.

All the Grim Reapers, all the invaders, felt a tremor originating from the depths of their souls.

They seemed to see a black sun slowly rising on the horizon of Seireitei.

It was not a manifestation of light and heat, but an embodiment of "end" and "destruction".

"Come, powerful beings from another world."

Captain-Commander Yamamoto pointed his charred katana at Kaido in the distance.

"Let me show you the strongest Zanpakuto in Soul Society in a thousand years."

His figure vanished from the spot in an instant.

The next second, he appeared in front of Kaido, and with a simple and unadorned trajectory, he gently swung the Zankatana in his hand towards Kaido's neck.

There were no flames, no sword pressure, only pure, extreme heat that reduced everything to nothingness.

"The Blazing Blade - East - Rising Sun Blade!"

laugh--!

There was no earth-shattering noise, only a soft sound like cloth being torn.

Kaido's pupils suddenly shrank to the size of a dangerous pinhead.

He didn't even see the other person's movements clearly, but he felt an indescribable, terrifying heat that seemed to instantly evaporate his soul rushing towards him!

Danger!

Extreme danger!

This was the first time since Kaido's debut that he had felt such a clear and potentially fatal threat, except against Lynn!

In the face of life and death, Kaido unleashed his full potential.

"Ohh ...

He looked up and let out a dragon roar that shook the heavens and earth. He unleashed his full Armament Haki to its limit without reservation. The pitch-black Haki covered his entire body like liquid, forming an incomparably thick black armor.

At the same time, he gathered all his power into the spiked club "Eight Precepts" in his hand, combining the destructive power of the Eight Gates and the twenty times Kaioken, and fiercely met the charred blade!

"Overlord - Thunderous Eight Trigrams!!!"

when!!!

The spiked club and the broken fire katana collided solidly.

This time, there was no clash of energies, no sweeping air currents.

At the point where the two meet, space twists and collapses eerily, as if a black hole has been burned out.

Kaido felt an irresistible, pure "melting" force coming from the opponent's blade. His indestructible spiked club, which was infused with all his power, melted and evaporated silently at the moment of contact, just like ice and snow!

Along with the overwhelming Armament Haki covering him, it was also "erased"!

"What?!"

For the first time, Kaido's maniacal laughter froze completely.

For the first time, his proud and seemingly indestructible body felt the fear of being "disintegrated" before the charred blade.

"It's not over yet!"

Captain-Commander Yamamoto's eyes were as cold as frost. With a flick of his wrist, the blade of the Zanka Katana drew a tricky arc, bypassing the spiked club and stabbing straight at Kaido's chest!

If this stab lands, Kaido's so-called immortality will probably be completely evaporated in an instant, leaving not a single cell behind!

"Don't even think about it!"

Kaido roared and, at the critical moment, suddenly released his spiked club, his huge dragon claw grabbing fiercely at Captain-Commander Yamamoto's wrist!

However, Captain-Commander Yamamoto was extremely experienced in battle. He seemed to have anticipated Kaido's movements. With a swift movement, he dodged Kaido's dragon claw at an incredible angle, while simultaneously placing his other hand on Kaido's massive abdomen.

"Burning Flame Katana - South - Ten Trillion Fire Death Burial Formation!"

Rumble rumble rumble—!!!

The earth trembled violently.

Centered on Kaido, countless charred corpses and withered bones burst forth from the cracked earth!

Those are all the souls who died under Yamamoto Genryusai Shigekuni's "Ryujin Jakka" over the past thousand years!

At this moment, these souls were awakened by the power of the Zankatana, transforming into an endless army of skeletons with hellfire burning in their eyes. They roared and howled, surging towards Kaido like a tidal wave. With their bones, they tightly bound Kaido's limbs, firmly imprisoning him in place!

"Get out of here! You scum!"

Kaido struggled frantically, his powerful force shattering countless skeletons into dust, but the skeletons seemed endless, instantly reforming after shattering and charging forward fearlessly.

"it's over."

Captain-Commander Yamamoto reappeared before Kaido, raising his Zankatana high.

"Remnant Fire Taishou Nishi——Remnant Prison Clothes!"

Om-!

A terrifying heat exceeding 15 million degrees Celsius, like the core of the sun, transformed into an invisible armor of fire, covering Captain-Commander Yamamoto's body.

He was like the sun on earth; the heat he radiated from his mere presence was enough to turn everything around him to ashes.

"Let your death put an end to this insolent invasion."

With a blank expression, Captain-Commander Yamamoto slowly slashed down at the bound Kaido with his Zanpakuto, which was imbued with the power of the sun!

For the first time, a look of "despair" appeared in Kaido's eyes.

He discovered that all his strength and all his defenses seemed so pale and powerless in the face of this one strike.

He could almost see himself being completely burned into nothingness in the future.

However, at this very last moment of life and death.

A childish voice, tinged with a hint of impatience, drifted down from the sky.

"Hey, old man."

"Who gave you permission to harm my father?"
