Obsessed with Haki in One Piece

Reincarnated into the world of One Piece, a former Haki-obsessed fan awakens as Spectre D. Ash, the son of a brilliant scholar and a deadly underworld legend. Born on the island of O’Hara—destined for destruction—Ash carries a dangerous legacy: a bloodline feared for its monstrous Haki, natural communion with the sea, and an ancient rejection of Devil Fruits.



Outwardly, Ash is an eccentric prodigy, all smiles and scholarly quirks. Inwardly, he's a calculating, ruthless strategist determined to master the full potential of Haki and alter the course of history. With a mysterious system—the Haki Mastery Codex—guiding his evolution, Ash sets his sights on unraveling the forbidden secrets of his lineage, forging bonds, and surviving the coming purge.



As the World Government watches in silence, Ash must embrace his inner Reaper, awaken the legacy sealed within O’Hara’s library, and defy the fate of annihilation.



But power comes at a price.

And ghosts of the past are never far behind.
