One Piece: sign-in to Ryujin Jakka

If this was just a small matter… then Admiral White Dove must surely have a way to resolve it!

Hearing Neptune's hopeful tone, Roman chuckled lightly and responded, "There is a way… but it might be a little dangerous~"

"Dangerous?!"

Shirahoshi's eyes widened in panic. Her delicate hands clenched tightly, and in the blink of an eye, tears began to well up in her large, innocent eyes.

"Don't worry. I still have some confidence in my own strength…"

BOOM!!

At that moment, the sea dragon struck the protective bubble of Fishman Island once again!

The deep, thunderous crash echoed like a hammer pounding on everyone's hearts.

Neptune's expression darkened further. A shadow loomed over his royal features.

Roman's smile faded. He looked around at the gathered group and spoke solemnly, "But no matter what you see next… I ask that you never speak of it to anyone else."

Hearing this, Neptune thumped his chest and assured him, "Rest easy, White Dove. We're soon to be family, after all. No matter what happens, not a single word will escape from us!"

Shirahoshi also nodded earnestly.

In her heart, Roman was already her destined one.

To her pure soul, Roman had become the most important person in her eyes.

With their reassurance, Roman gave a slight nod. Then he inhaled deeply, his body beginning to emit a swirling aura of white light.

"Susanoo—White Dove!"

In the blink of an eye, a massive white giant took form behind him.

From the back of this white colossus, a pair of divine, snow-white wings stretched open wide, radiating elegance and majesty. The wings flapped with immense force, lifting Roman into the air as he flew straight toward the outside of Fishman Island.

Everyone present was utterly stunned by the sight.

"What's Admiral White Dove trying to do?!"

"Is he actually planning to go outside… to fight that 10,000-meter sea dragon in the deep sea?!"

"No, he can't! Roman! Come back!!!"

Not a single person believed that Roman could actually accomplish such a feat.

He was a Devil Fruit user—once he entered the sea, the curse buried in his very soul would rob him of all his power! Even without that… the sea pressure at that depth would be enough to crush any living creature into paste!

Such terror… ordinary people wouldn't even survive for a moment.

Yet, Roman chose the most dangerous path. How could Neptune and Shirahoshi not be alarmed?

Tears streamed down Shirahoshi's face uncontrollably.

"Roman, if you don't come back alive… then I won't live either! You gave me freedom. Without you… What good is my freedom?!"

Neptune's heart twisted at her words. A bitter smile tugged at the corner of his lips. He could only pray that Roman would succeed. Because if Roman failed… then Fishman Island would be doomed.

Shyarly watched Roman's soaring figure, her heart shaking.

In that moment, she realized something.

Even with her 100% accurate fortune-telling… in the face of such unwavering determination, fate itself seemed less terrifying!

She collapsed weakly to the floor, muttering to herself:

"Maybe… Roman really can change what is to come…"

Roman folded his arms calmly, controlling the mighty Susanoo formed from his Illusion-Illusion Fruit, and plunged into the dark depths of the ocean.

This… this was the very reason he had ordered Ain and Stella to leave earlier.

Not only because of Shirahoshi's identity as Poseidon. But more importantly, because from the very beginning, Roman had already decided to subdue the sea dragon in this way!

That's right. Not destroy.

Subdue!

From the moment the sea dragon appeared, Roman had set his sights on it.

A Sea King over 10,000 meters in length—something that existed only in myth and legend. Very few people in the world had seen such a creature. And of those who had, most were long dead. To tame such a beast… how exhilarating would that be?

A glimmer of excitement flashed in Roman's eyes.

With another powerful flap of its wings, the Susanoo stirred up raging currents.

Roman's body broke through the protective bubble of Fishman Island and entered the ocean depths. The crushing pressure of the deep sea pressed down on him from all directions.

But thankfully, the Devil Fruit Roman had consumed had no side effects.

Even in the sea, he could still use his Devil Fruit powers freely.

The Susanoo, forged from the power of illusions, was wrapped in a coating of Armament Haki—allowing it to withstand the immense ocean pressure and facilitate the continuous cycle of Roman's breath.

The seawater was completely forced away from his body.

This balance was absolutely essential.

"Hey, listen. If I beat you, become my mount, alright?"

Roman used his power to communicate with all things and spoke to the sea dragon.

But his words… clearly provoked it!

This was the overlord of the deep sea! Ten thousand meters in length! If it rose upright, it could stretch from Fishman Island all the way to the surface!

Yet Roman dared to say… he would make it his mount?! Its pride would never allow such a thing!

ROARRRR!!!

Through the power of communication, Roman understood its response.

"You think I can't beat you? Then let's test that theory!"

Roman didn't waste another word.

Controlling the towering Susanoo, he charged at the sea dragon. More like away from the sea dragon.

To be precise, he was deliberately drawing the beast away from Fishman Island.

He couldn't risk the island being destroyed by the aftershocks of their battle.

ROAR!!!

The sea dragon bellowed again.

Through their connection via his ability, Roman understood its message:

"Don't you run from me, brat!"

Ten thousand meters beneath the ocean, Roman used the immense strength of his Susanoo and peak-level Armament Haki to forcibly carve open a path through the sea itself.

If anyone else saw this scene, they would be beyond shocked.

A Devil Fruit user… moving freely within the ocean?

The world would never believe it!

If word spread, Roman would instantly become the target of the entire world.

That's why… he had to be cautious.

"Huff… fighting in the deep sea is such a drain on stamina…"

"What's wrong, brat? Tired of running already?!"

Hearing the sea dragon's taunting roars, Roman stood proudly inside the Susanoo, arms crossed, and smirked.

"Nope. I'm not running anymore."

"Because now… we've moved far enough perfectly!"

"Far enough?"

Before the sea dragon could react—

Roman began to chant:

"Carriage of thunder, bridge of a spinning wheel. With light, divide this into six.

Bakudō #61- Rikujōkōrō (Six Rods Prison of Light)

As his voice echoed through the ocean…

In the pitch-black abyss, six massive beams of light suddenly burst into existence!

The golden rods struck out with blinding speed—slamming into the sea dragon and locking its massive body in place!

And this… was only the beginning.
