One Piece: The Unrivaled Dragon Man: I am God's Agent!

Reborn as a Celestial Dragon, while others yearn for the Holy Land, I—Celestial Dragon Isaac—am born invincible, incredibly wealthy, and in control of the entire world! What? Celestial Dragons are just weak-willed villains? I'm a true Celestial Dragon! Celestial Dragons aren't just noble; they possess divine power inherited from ancient times! Devil Fruits? My constitution is immune to all curses! Marine Admirals? With a single command, they're all my watchdogs! The Four Emperors? Sorry, the Four Emperors have to kneel before me and call me "Sir"! After my rebirth, I activated a god-level system. Being a Celestial Dragon is no longer a burden, but a passport to supreme power! Controlling destiny, dominating the world, even Im has to give way! I will make everyone understand—I am a Celestial Dragon, I am a god, and what I say is destiny...
