"One Piece: Sign-In at the Start to Get Ryūjin Jakka"

West Blue, Seagull Island.

A ruthless fight has erupted over the "Fruit of Surgery"!

"Corazon, tell me where Roya is… or else!"

On the white snowy ground, Doflamingo toyed with the heart-shaped fruit in his hand and laughed maniacally.

Then he raised a hand and pointed to the sky.

"Everyone on this island… will die because of you!"

Countless sharp and durable white threads spread out from Doflamingo's body, rooting themselves across the entire island.

The threads rained down from the sky like a deadly net. Those who came into contact with them lost control of their bodies, raising their fists or weapons and beginning to slaughter one another.

Some were luckier—not ensnared—but when they tried to pass through the Birdcage, their bodies were instantly sliced apart by its razor-sharp threads.

In mere moments, the island was transformed into a slaughterhouse of carnage and madness.

Blood stained the once-pristine snow, freezing into crimson rivers of ice.

"Birdcage…!"

Corazon's pupils shrank sharply at the sight.

As a Marine undercover agent, Corazon knew all too well the cruelty of Doflamingo.

He truly was capable of such atrocities. Even if Corazon told him everything, he'd likely break his promise anyway.

But the justice burning in his chest wouldn't allow him to yield.

"There's really… no other way?!"

Corazon lay helpless on the ground, riddled with bullet wounds, barely hanging on through sheer willpower.

But—

What use was that?!

"Roya…"

The light in Corazon's eyes began to fade…

Suddenly—

A blazing inferno shot into the sky from the western side of the island, radiating intense heat and energy!

At that moment—

The snow stopped.

The wind ceased.

As if the entire world had come to a halt before the roaring flame.

"W-What is this?!"

Doflamingo suddenly sensed a terrifying force silently rushing toward him. As a seasoned underground broker known as Joker, his body instinctively unleashed Conqueror's Haki in defense.

But—

BOOM!!!

The supposedly unbreakable Birdcage was torn apart like paper by that pillar of fire.

Then, the searing flames burst into a storm of heavenly fire in midair, raining down and engulfing the entire island.

In an instant, the domineering flames melted the thick snow, creating a scene of apocalyptic grandeur.

Even the fruit in Doflamingo's hand was snatched away by the sudden surge of fire!

His veins bulge in fury, his body trembling uncontrollably.

"Damn it, my fruit! Just how strong must someone be to launch such an attack?! Damn it!"

Victory had been within his grasp. But now, the fruit was gone, the Birdcage destroyed, and Vice Admiral Tsuru would soon arrive with the Marines…

On top of that, there was now a powerful unknown force.

All of it together sent Doflamingo into a near-frenzy. But there was nothing he could do!

Gritting his teeth in frustration, he turned to the Donquixote Family and roared:

"Retreat!"

At sea, the Marines had also been shaken by the heavenly flames.

"I didn't expect Doflamingo to move so fast! Change of plans—land on the island immediately. Be cautious. There may be other forces at play."

Vice Admiral Tsuru frowned at the overwhelming force she had just witnessed. But the value of the Fruit of Surgery was beyond comparison!

Meanwhile, in a remote part of the island—

Roya, who had just transmigrated into the One-Piece world, sheathed his sword—Ryūjin Jakka, the Blade of Flames—and caught the fruit that had been swept up by the firestorm.

A slight smile curled on his lips.

"So, this is the reward from the sign-in system? It's seriously overpowered."

Ding! Product of the system—quality guaranteed!

This is the God-Tier Sign-In System. Sign-in reward at Seagull Island:

Ryūjin Jakka—strongest and oldest fire-type Zanpakutō. Its spiritual pressure upon release rivals Conqueror's Haki.

Ding! Sign in at famous canon landmarks to earn bonus rewards!

Note: Must be within a certain range to trigger successful sign-in!

After hearing this, Roya became even more excited to collect rewards from famous places in the One-Piece world.

Just then, a figure came into view.

As a transmigrator, Roya instantly recognized the child—it was Trafalgar D. Water Roya!

One of the future Seven Warlords of the Sea.

He didn't expect to encounter him here and now.

Roy cautiously observed Roya. He had escaped with Corazon's help and now witnessed this man destroy the Birdcage with a single strike.

Such overwhelming power—surely, he could save Corazon!

Roya felt intimidated by the man, but thinking of Corazon's desperate situation, he gathered his courage and stepped forward.

"P-Please… please help me! Save Corazon!"

Roya's voice was barely audible at first, but as he thought of Corazon, he cried out louder.

Roya walked past him without a word, as if Roya didn't even exist.

Unwilling to give up, Roya once again ran after him, pleading:

"Please! Save Corazon! He's a good man! He's the most important person in my life!"

"If—if you save him, I'll do anything! I'll give you everything I have! Please, I beg you!"

At that moment, the heart-shaped fruit hit Roya gently on the head, then dropped to the ground.

Staring at the fruit, Roya's eyes lit up. He trembled as he picked it up with both hands.

Then from a distance, Roya's voice echoed—

"Use your own strength… to save the one most important to you."

Hearing this, Roya wiped away the tears about to fall from his eyes.

In his heart, he vowed to follow this man for the rest of his life.

Because without him… he would've lost the person most precious to him.

Corazon gave Roya hope with the Fruit of Surgery—

Now, Roya would use it to bring Corazon a miracle.

Thinking of it that way…

It wasn't a bad trade.

And by the time Roya came to this realization, Roya had already left the island—

As if he had never been there at all.
