The day after Monkey D. Luffy sets sail from Foosha Village, another pirate begins his journey not for glory, treasure, or infamy, but for something far more precious: A family.

Kael D. Raen, Luffy’s third-eldest sworn brother, is a hybrid of Oni and Buccaneer blood towering, fierce, and carrying the weight of generations on his shoulders. Hidden from the world by fate and fire, Kael finally steps into the Grand Stange not to conquer it, but to protect the ones who will. His goal is simple: carve out a place where his younger brother can dream freely, shield him from the world’s cruelties, and gather his own strange crew of lost souls along the way.

But Kael’s lineage is anything but simple. Born of a mysterious union, he’s tied to the greatest names in the sea being a member of the D clan and having ties to his brothers Ace, Sabo, and Luffy.

As rival powers clash and ancient truths surface, Kael will forge bonds, face monsters from both sea and soul, and build a harem of powerful, loyal women drawn to his strength and his heart. For Kael, this isn’t just an adventure it’s the rebirth of a legacy.

And if the world dares to threaten his brother…
They’ll learn exactly what it means to face the wrath of a Raen.

I have decided to rewrite the fanfic and make some changes. I will try to have it out by the end of the month.
