Prologue – Judgment and Redemption
The sea is vast. The truth is deeper.
Long before the age of Straw Hat Luffy, when Gol D. Roger's voice still echoed in the winds and the fires of revolution flickered on distant islands, the world already harbored legends, hidden in its shadows.
In this age of pirates and absolute justice, two children were born in different corners of the world. One among the forgotten, the other among the untouchables. The world would remember their names as echoes of opposing forces: Gokusei and Hokushin.

South Blue – a winter morning, the sea whispering ancient truths.
In the slums of a remote island, a child with dark skin, short, wavy black hair, and a soul tempered by hunger and street fights, walked barefoot between broken alleys and burning barrels. His name: Gokusei – "Star of Captivity." He never knew peace, only survival.
His mother, a dying woman with a golden heart and a Vivre Card necklace around her neck, left him only a phrase and a name: "When you feel lost, follow the paper to him... to your brother, Sengoku."
Years passed. Gokusei became strength. Muscle. Hammer. Judgment. He wielded a warhammer named Shinpan, forged from scrap metal and hatred, and consumed a mythical Zoan fruit: Ashura Ashura no Mi. Its power awakened not only his fury but a doctrine born from his soul. Justice.
But his justice was not the World's. It was his own. Unyielding. Sharp. And true.

On the other side of the world, in the ruins of a decayed palace in Mariejois, a child descended from the Celestial Dragons watched the blood of his family drip onto golden tiles. His name was Hokushin – "Divine Truth."
Expelled by his lineage, surviving in shadows, he was taken in by a forgotten cult that whispered to him since childhood: You are divine. You are forgiveness.
But Hokushin never forgave.
He consumed a cursed fruit that stole suffering instead of offering it. Like a Dementor, he kissed the soul and left the void. His Conqueror's Haki wasn't born of ideals, but of illusion and narcissism. To him, the world was a stage, and he was the God who would rewrite peace with blood.
He created a sect. The Hakushin Doctrine. And where Gokusei judged, Hokushin "redeemed"—with death.

Years later...
The Grand Line trembled. Rumors of a hammer that weighed hearts and a ghost that stole pain spread among pirates and kings. Marine bases debated strange reports. Slave revolts broke out. Nobles were found dead with peaceful smiles on their faces—after having confessed everything and... disappeared.
Meanwhile, Gokusei fought silently. In the shadows. His head transformed into the Ashura's form, whispering the activation phrase:
> "What weighs more, your heart or a feather?"
The enemy would see a hallucination. A scale. On one side, a feather. On the other, their own soul.
And if they were found guilty... they burned.
Hokushin, smiling in some distant cathedral carved into a cliff, whispered to his followers:
> "He judges. I forgive. But only I can determine what is pure."
The two would meet. Not in peace. Not in war. But in something older and more dangerous: conviction.
For in a world where pirates seek freedom and the World Government seeks order—there are forces that seek something much deeper:
Judgment and Divinity.
And the New Era would not be defined by a single D, but by the eternal conflict between Gokusei and Hokushin.
