Should we dive into the Luffy used during this fight, or

Luffy didn’t answer with words. He planted his feet, his shadow stretching across the floor. He wasn't just fighting a fishman anymore; he was fighting the very concept of Nami’s imprisonment. With a roar that shook the foundation of the tower, Luffy leaped into the air. "Gomu Gomu no... Axe!"

Arlong sneered, his massive saw-toothed blade, Kiribachi , leveled at Luffy’s throat. "You think destroying this room frees her? She belongs to the Arlong Pirates. Her talent is my property!"

"Nami," Luffy grinned, his face covered in soot but his eyes bright. "You're our navigator now. Let’s go."

His leg stretched upward, piercing the clouds, before crashing down with the weight of a falling mountain. The floor groaned and gave way, the entire building splitting under the sheer force of his fury.

She looked at her arm, where the Arlong Pirates' tattoo was now a mess of blood and scars from where she had tried to carve it out. She realized then that Luffy wasn't just breaking the stone walls of the park; he was breaking the chains on her heart.

As the dust cleared, Arlong lay defeated in the crater of his own empire. Luffy emerged from the wreckage, placing his signature straw hat back onto Nami’s head—the ultimate sign of his trust.

"Luffy!" she screamed, her voice cracking but steady. "Finish it!"
