Koseizoku
In a world three times the size of Jupiter, most are ordinary—yet a rare **8%** are born marked by the **Irregular Factor**, a mysterious anomaly that grants supernatural abilities. These gifted few are feared, worshipped, and hunted. They are called **Irregulars**, and every one of them is a potential threat to the established order.
Humanity sails an endless oceanic frontier in the **Golden Age of Piracy**, where legends travel faster than the wind and danger lurks beyond every horizon. At the top of the lawless world of pirates stand the **Six Hexarchs**—the six most powerful Irregulars alive, each commanding enough might to topple nations. Their names alone can start wars… or end them.
The tyrannical **Navy** enforces justice upon the seas, led by the ruthless **Admirals** and overseen by the mysterious **Vanguard Conclave**, the world’s unseen puppeteers. Below these shadowy elders are the god-like **Heavenly Scions**, nobles whose cruelty is matched only by their privilege. To counter the power of piracy, the Navy has even allied with outlaws: seven state-sanctioned pirate lords known as the **Seven Sea Reavers**, each allowed to ravage the seas in exchange for loyalty.
But everything changes with the legend of the **Genesis Sigil**—an ancient relic said to be the first object ever touched by the Irregular Factor itself. Whoever claims it will gain *absolute dominion* over all Irregular powers. For the world’s strongest, it is the key to supremacy. For the oppressed, it is the key to freedom. For the wrong hands… it could mean the end of the world.
Across the boundless ocean rises a new pirate crew chasing dreams, revenge, and the truth of the Irregular Factor itself. Their journey will cross warlords, admirals, tyrants, and gods, igniting a storm that will reshape the world.
**This is the story of Koseizoku—where destiny is earned, not granted.**
(With a respectful nod to the legendary adventures that inspired it, especially *One Piece*.)
