One Piece: My Haki Can Devour Everything!

Rayne was a slave of lowly birth, barely surviving in the shadow of the World Government. When he witnessed the person he loved being mercilessly trampled underfoot, despair and fury ignited an ancient, forbidden power within him: a terrifying form of Haki capable of devouring his enemies' "will" and "strength"!

From that moment on, he was no longer a lamb waiting to be slaughtered, but a demon crawling out of the abyss.

Devour the malice of pirates to strengthen his body! Devour the Marines' iron resolve to temper his Armament Haki! Devour the will of the powerful to steal their skills and insights! He can even devour Devil Fruit abilities and make them his own!

From an unknown nobody in the East Blue, to shaking the world across the Grand Line, to claiming the throne of the New World. Rayne leads his companions on a path of constant devouring and growth, paving the way to a throne of freedom and revenge with the flesh and blood of his enemies!

Celestial Dragons? The World Government? The Four Emperors? Marine Admirals? Before my Devouring Haki, your arrogance and strength will all become fuel for my growth!

This is the story of a slave who rises to become a ruler of the seas, overturns the old world, and ushers in a new era!
