One Piece: Roger’s Heir Starts with Pirate King Template Fusion

Transported into the world of One Piece, I became Monkey D. Yan, Ace's long-lost older brother, and triggered the Awakening of the system:

Pirate King Template Fusion System
Defeat powerful opponents to extract their ability templates, then fuse three into one for an upgraded power!

Right from the start, I fuse Luffy's rubber body, Ace's Flame-Flame Fruit, and Garp's Iron Fist to create the one-of-a-kind Flame Emperor Physique: flames that stretch like rubber, undying fire coated in Armament Haki, and a single punch that unleashes a hundred-meter fire dragon to tear the sea apart!

In this life, I will never let Ace die again! The Paramount War? A whole year before it happens, I storm Marineford alone and broadcast the Celestial Dragons' crimes to the world! Blackbeard? The moment he shows up, Whitebeard and I join forces to beat him half to death! As for the Flame-Flame Fruit, I evolve it into soul fire that never goes out!

From steamrolling the Seven Warlords of the Sea in the East Blue to taking on the Four Emperors head-on in the New World and turning Navy admirals against their masters-when all four brothers finally reunite at Laugh Tale, we discover that the truth behind One Piece is actually...

"Luffy, you become the freest Pirate King of all. Ace, you marry Makino and live a peaceful life. As for me-" I point at the starry sky above. "The Will of D. means the dawn-and the boundless sea of stars!"

An accessible, fast-paced power fantasy with smart characters, hot-blooded brotherhood, and no bleeding-heart mercy. Roger's bloodline will become the Celestial Dragons' greatest nightmare!
