One Piece: I Dominate the World with Martial Arts!

In the treacherous era of the Grand Line, where Devil Fruits and Haki are the ultimate symbols of power, the protagonist unexpectedly transmigrates and awakens a god-tier "National Martial Arts Grandmaster System." He makes a shocking decision: reject the reliance on supernatural fruits and conquer the seas with pure, unadulterated martial arts! His core directive is ruthlessly simple: forge his body into the ultimate weapon, master the true essence of Kung Fu, and crush every opponent with the sheer force of human will! Armed with this reality-bending martial prowess, his journey completely shatters the traditional logic of the One Piece universe. While legendary pirates and Marines struggle to master their abilities, the protagonist is casually redefining the meaning of true supremacy. Whether it's using Eight-Trigram Palm to shatter Logia intangibility, employing Taiji to redirect Admiral-level attacks, or standing toe-to-toe with the Four Emperors using only his fists, his unapologetic rise redefines the meaning of true supremacy. From an unknown martial artist to the undisputed apex existence who proves that Kung Fu is the ultimate path, he turns the entire ocean into his personal stage of divine combat. This is the ultimate unapologetic anime power fantasy about achieving absolute supremacy through extreme "martial arts mechanics" and supreme "ocean domination." If you love mind-blowing combat feats, watching arrogant fruit users and Haki masters get completely outclassed by a max-level protagonist's god-tier Kung Fu, and experiencing the most satisfying and unconventional One Piece conquest ever, this is the definitive anime masterpiece!
