One Piece: Max-Level Armament Haki at the Start!

In the perilous era of the Grand Line, a modern soul unexpectedly transmigrates into the world of One Piece, landing right in the Marine Headquarters' recruit camp. Just as he awakens a god-tier "Haki Sign-in System," he makes a ruthless choice: instead of flashy Observation or Conqueror's Haki, he pours all his initial points into Armament Haki! His core directive is ruthlessly simple: achieve max-level hardening, punch through every obstacle with brute force, and establish absolute dominance through sheer physical invincibility! Armed with this reality-bending defensive power, his journey completely shatters the traditional logic of the One Piece universe. While legendary pirates and Marines struggle to break through enemy defenses, the protagonist is casually redefining the meaning of true supremacy. Whether it's effortlessly shattering a Vice Admiral's iron body with a single punch, tanking Admiral Akainu's devastating magma fist without a scratch, or standing unyielding against the World Government's strongest forces, his unapologetic rise redefines the meaning of true supremacy. From an unknown recruit to the undisputed apex existence who stands above all legends, he turns the entire ocean into his personal stage of divine domination. This is the ultimate unapologetic anime power fantasy about achieving absolute supremacy through extreme "max-level mechanics" and supreme "Armament Haki domination." If you love mind-blowing power scaling, watching arrogant villains and legendary pirates get completely outclassed by a max-level protagonist's god-tier defense and strength, and experiencing the most satisfying and unconventional One Piece conquest ever, this is the definitive anime masterpiece!
