Uchiha Puppet Master, Starting from One Piece.

Something's wrong.

He looked down at his chest.

That shallow knife mark.

The white feather left a knife mark in the gap of the parry.

Kaido's Observation Haki was roaring wildly.

wrong.

Something's wrong.

He looked down at his chest.

That shallow knife mark.

The white feather left a knife mark in the gap of the parry.

That knife wound from which only a trace of blood seeped.

At this moment, the knife mark was emitting a faint blue light.

It's very light.

So faint as to be almost invisible.

But Kaido saw it.

Because his Observation Haki told him that the blue light shouldn't exist.

"What's this?"

Kaido's dragon eyes shrank to the size of pinpoints.

Bai Yu did not answer.

His Mangekyou Sharingan slowly rotated, the patterns deep within his pupils spinning like windmills.

He flicked his finger lightly across the blade.

"clang--"

A crisp whistling sound rang out.

The sound was very soft, as soft as a drop of water falling into a deep pool.

But to Kaido, the sound was like thunder.

Because with that clang of the blade, the entire world before his eyes changed.

No.

It hasn't changed.

Instead... it cracked.

It was like a mirror shattering in the middle, with cracks spreading outwards, each crack emitting a blinding white light.

Kaido's dragon eyes widened suddenly.

He wanted to unleash the Eight Precepts, to release Conqueror's Haki, to do something.

But he couldn't move his body.

It wasn't because he was restrained, but because his brain was overwhelmed by a massive amount of information in that instant.

He saw—

Bai Yu stood in three different positions.

He saw—

He threw his eight precepts in three different directions.

He saw—

There are three moons in the sky.

He saw—

There are three pits in the ground.

Every scene was so real, so real that even his Observation Haki told him that it was all true.

But Kaido knew.

It's impossible that everything is true.

Bai Yu's voice came from all directions, not from the left, not from the right, not from the front, not from the back, but from every direction, from every grain of air, from every ray of light.

"A hallucination! When? Could it be his strange eyes?..."

"From the very beginning."

Kaido fell silent.

He closed his eyes.

Then, he opened his eyes.

What burned in the dragon's eyes was not anger, nor fear, but fighting spirit.

An even more fervent fighting spirit.

"interesting."

"This is very interesting, Uchiha Shiraha."

"Your abilities, your strength..."

"It all makes my blood boil!"

His body began to swell.

It's not the kind of expansion that comes in a human-beast form, but a more thorough and violent expansion.

Blue scales emerged from beneath his skin, each scale as if cast from steel, with edges as sharp as knives.

His bones were cracking, and his body was stretching rapidly.

His limbs transformed into dragon claws, which were as thick as mountains.

Full dragon form.

The true form of Kaido of the Beasts.

It was not the human-beast form chosen to balance speed and power as before, but a pure, destructive Azure Dragon body that staked everything on power.

"Roar--!!!"

A dragon's roar tore through the night sky.

The sound, carrying the oppressive aura of Conqueror's Haki, spread outwards, shattering all the ruins within hundreds of meters.

The dark clouds in the sky were torn to shreds by the sound waves, and moonlight poured down, illuminating the enormous creature that hovered in the air.

Kaido the Azure Dragon.

It is over 300 meters long.

Dragon's eyes, like two blood moons, coldly gazed down at the white feathers on the ground.

"Boy."

Kaido's voice came from the dragon's mouth, like rolling thunder.

He opened his dragon mouth, and crimson flames began to gather between his fangs.

"If you think you can defeat me like this, you're being incredibly naive!"

"Heat Breath—!!!"

A crimson beam of light shot out from the dragon's mouth, exceeding ten meters in diameter, with a temperature high enough to instantly vaporize steel.

This attack wasn't aimed at Bai Yu, but rather at a radius of several hundred meters around him.

Indiscriminate attack.

Since we can't see the real enemy, let's destroy everything in front of us.

Bai Yu's eyes sharpened.

His body disappeared from the spot.

Instantaneous movement technique.

The next second, he appeared hundreds of meters in the air, looking directly at Kaido's dragon head.

"Susanoo?"

His Mangekyou Sharingan spun wildly.

A massive surge of chakra erupted from his body, coalescing into a gigantic skeleton around him.

The skeleton grows rapidly, producing muscles, skin, and armor.

Susanoo - Complete Form.

A black giant, over a hundred meters tall, appeared in the air, with wings on its back and a long sword made of chakra in its hand.

The giant's armor was wrapped in black Conqueror's Haki, intertwined with chakra to form a strange pattern.

Bai Yu stood between Susanoo's eyebrows, arms crossed, looking down at the Azure Dragon opposite him.

"Is this your true strength?"

Kaido's voice was filled with excitement.

"Is this your true strength?!"

Bai Yu did not answer.

His Susanoo swung its long sword, slashing towards Kaido's dragon neck.

Kaido's dragon claws came at him, five sharp claws wrapped with blood-red Conqueror's Haki lightning.

"clang--!!!"
