The Age of Pirates had ended.
Or so the world believed.
Centuries after the death of Monkey D. Luffy, the man hailed as Pirate King, the seas were forever scarred. The Red Line had crumbled, the oceans had calmed, and the great tides that once drowned islands had fallen away. Where once there was endless water, new lands emerged—ancient ruins, forgotten kingdoms, and treasures swallowed by the sea now bared themselves to the greedy and the brave.
But peace never lasts.
The World Government was shattered, its proud fleets and admirals turned to dust. In its place rose something far more insidious—an organization cloaked in shadows, whispering an old name like a curse.
I-M-U.
The remnant rulers sought not justice, not peace, but perfection. Through forbidden science and the remnants of Celestial power, they hunted for the one who could stand as the perfect being to once again chain the world beneath their rule.
And it was in their cold prisons, among screams and shattered dreams, that a man was born to infamy.
Davy D. Xavier.
A descendant of the most cunning pirate the seas had ever known—Marshall D. Teach, Blackbeard.
Branded a failed experiment, injected with a monstrous power said to warp the very laws of the sea, Xavier should have perished. But like his bloodline before him, he laughed in the face of fate. With a smile as mocking as the devil and a will sharp enough to cut the heavens, he broke his chains and freed the other wretches tortured beside him.
Yet the seas he now faced were not the same.
Devil Fruits had become rare, shunned as relics of an older age. The world now bowed to a greater force—Haki. Masters of will so strong they could commune with nature itself, shaping reality according to their spirit. These warriors stood as gods, their power revered as ancestral awakening spread through bloodlines across the world.
But Xavier was no ordinary pirate.
He bore not one Devil Fruit, but two. The Magnitude-Magnitude Fruit, capable of bending mass and weight itself, and the Cut-Cut Fruit, a cursed power that could slice through all things, tangible or not. Together, they made him not a man—
but a calamity.
Yet the path to becoming the one above all is drenched in blood.
The Seraphic Order of Neo-Celestial Dragons plots to reclaim the heavens, wielding the reborn power of gods like the Nika Fruit and the Uo Uo no Mi.
The Neo-Marines march with justice twisted into tyranny.
The descendants of the Underworld Guilds sharpen their knives for dominion.
The Supernova Pirates seek crowns, and even the Moon itself brims with invaders from the stars.
And above them all sails a single man who embodies the will of freedom itself, wielding Haki that makes the impossible real—Xavier's greatest rival.
The world is once again a stage for dreams and nightmares.
And on that stage, one man bears the grin of his ancestor, the hunger of a devil, and the patience of a viper waiting for the kill.
His name will resound across the seas.
Davy D. Xavier.
The man who will cut down gods, crush empires, and carve his name into the bones of the world.
For the age of pirates has returned—
and this time, it will not end with a king.
It will end with a devil.
