“When a cursed bloodline awakens, the Straw Hat Pirates face their darkest voyage yet.
After encountering the enigmatic Eternal Twilight Clan—an ancient vampire race guarding secrets older than the Void Century—Sanji’s Germa-engineered DNA collides with a vampiric curse, transforming him into a hybrid of science and nightmare. Now, as bloodlust wars with loyalty, the crew must navigate the Blood Moon Archipelago, a labyrinth of crimson mist where shadows whisper forgotten histories and every heartbeat could betray them.
From Claudia, the silver-haired Queen whose kiss binds Sanji to her dark legacy, to spectral warships haunted by Rocks Pirates’ ghosts, the Straw Hats unravel a prophecy: “When blood merges with steel, the Gates of Time will bleed.” But as Sanji’s powers spiral—flames turning ice-blue, senses piercing souls—the line between ally and monster blurs. Can Luffy’s unwavering faith outshine an eternal night? Or will the World Government’s buried pact with the vampires drown the New World in blood?
Blending One Piece’s signature adventure with gothic horror and sci-fi intrigue, Crimson Oath delivers a relentless saga of sacrifice, genetic rebellion, and the cost of immortality. Perfect for fans of vampire lore, epic sea battles, and moral dilemmas that cut deeper than a sword.“
