"Want to destroy the warship?
"Then give it a try!"
"Doflamingo."
Facing the three thousand lines pouring down like laser rain, a red light flashed in Rosen's eyes. He used his Observation Haki to see everything Donquixote Doflamingo was thinking and what would happen in the future.
This was the terrifying aspect of the three forms of Haki Refining method of his Haki Core . After practicing Observation Haki into the Haki Seed, as his progress deepened, Rosen's Observation became increasingly terrifying.
The ultimate realm of Observation Haki gained through training: foresight of the future.
The ultimate form of innate awakening: reading thoughts and memories, transmitting consciousness, and altering values and beliefs.
Through Refining his Haki Core, Rosen had mastered them one by one.
At this moment, Donquixote Doflamingo was like a transparent man before Rosen.
How transparent?
Everything Doflamingo thought and felt—even the changes in his emotions—were laid bare. Rosen foresaw every move, every deployment, before they even happened.
So transparent that unless Doflamingo's strength was several times greater than Rosen's, in the face of such Observation Haki he had already lost half the battle before it began.
Not to mention, Rosen's strength was more than ten times his.
"Alert!"
Although Doll's Observation Haki could not see the future, she sensed Doflamingo's intent from his attack. She ordered the navy aboard to be ready to fall into the sea if needed. She clenched her fists, prepared to intercept the incoming threads aimed at the warship.
But then she saw it—an overwhelming surge of Armament Haki spread outward from Rosen like a flood bursting through its gates.
Before the three thousand thread pillars could reach the warship, they were intercepted. Rosen's Haki covered the warship inside and out, wrapping every sailor on deck.
Then the Armament Haki transformed, becoming like crystal-thick energy armor. It coated the warship, the sails, the deck—every navy present.
From afar, the warship now looked clad in his armor, transformed into a colossal war beast entrenched upon the sea, unmoved by the incoming assault.
All three thousand thread pillars crashed down, piercing the hull, the masts, the sails, the deck—each impact exploding like thunder. The force set the waves heaving violently, rolling into towering walls of water.
But as the sea settled again, the warship remained afloat like a black tortoise plated in iron—untouched, unmoving, unscathed.
Even the sailors on deck were unharmed. They saw the pillars lunge toward them, but his purple armor encased them, stopping the threads before they could land a single scratch.
"We're saved!"
"Wow… incredible!"
"The Admiral's Armament Haki can not only form Susanoo and wield it through the Kokujō Tengen Myō'ō, but he can even wrap an entire warship with it to protect us!"
"Too powerful."
"Is this the monster who reached Admiral-level strength before even graduating from the Naval Academy?"
The sailors exchanged stunned looks.
For the first time, they were encased in Susanoo themselves, truly experiencing Rosen's power. The awe swept through them like a tidal wave, crashing through heart and spirit alike.
"This man."
"He's grown again."
"Compared to when he fought me, his mastery of Armament Haki has clearly reached another level."
No one felt it more than Douglas Bullet.
He remembered clearly—the last time Rosen fought him, he could only manifest Susanoo upon the Kokujō Tengen Myō'ō:
And now?
In a heartbeat, Rosen's Haki extended everywhere—armoring warships, protecting navies, reshaping the battlefield.
Such mastery required not only a titanic amount of Haki, but also precision control beyond anyone else's reach.
"Is this your power?"
"Vice Admiral Rosen."
Doll turned toward him, her beautiful face filled with emotion. She too, like every other sailor, was embraced within Susanoo's protection.
It felt like the North Sea beneath her feet—immeasurable, boundless.
"What is this?"
"Haki?"
"But if it's Haki, how could it be so immense?"
Donquixote Doflamingo's eyes widened behind his sunglasses.
This wasn't just imbuing Armament Haki to harden objects. It was releasing it outward, shaping it into armor-like manifestations that enveloped not just individuals, but an entire warship and hundreds of sailors.
And it had simply nullified his awakened String-String Fruit.
As he forced down his shock, trying to keep his will intact, the armor of Haki covering the warship suddenly surged upward, turning into a purple column of light that pierced into the heavens.
At the same time, the warship itself rose from the sea, climbing higher, until it hovered more than a hundred meters above the waves.
The sailors, though awed, did not panic. Holding their breath, they gazed at Rosen with unwavering trust. With him here, even if the seas and sky turned upside down, they would remain unshaken.
Boom!
Under Doflamingo's disbelieving gaze, a foot the size of a mountain emerged from the purple light, stepping upon the roaring current of the sea.
Then the torso, arms, neck, head, and folded wings followed.
The complete form of Susanoo appeared.
One hand gripped the warship. The other foot stepped upon the North Sea.
And before it even moved, a crushing aura swept across the battlefield like a typhoon. It pressed upon the hearts of Pica and Doflamingo alike, squeezing the breath from their chests.
A single word seared into their minds.
Invincible.
Yes—at this moment, Rosen was the incarnation of invincibility itself.
Rosen.
The name had become synonymous with that word.
"It's true."
"Not only has his Haki technique advanced, but the raw strength of his Haki has grown."
"Before, the fully-formed Susanoo stood only 180 meters. Now it exceeds 200."
Douglas Bullet, seated on the warship's chair, cast a glance at Rosen and spread his Observation Haki across Susanoo's colossal form.
He arrived at a terrifying conclusion.
In just one month, Rosen's Susanoo had grown by 20 meters.
It might not sound much—but 20 meters was the height of a full-grown giant.
And that entire increase was pure Armament Haki, condensed into form.
Which meant Susanoo's defense, speed, and strength had surged far beyond what they were a month ago.
