One Piece Chapter 52, page 5-7: OATH

Sanji is furious and bewildered by Zoro's actions, thinking, "THAT DAMN BASTARD'S OUT OF HIS MIND! HIS ENEMY WAS THE WORLD'S STRONGEST! THE RESULT'S OBVIOUS! IF IT'S GONNA MEAN YOUR DEATH, THEN JUST THROW YOUR DAMN AMBITION AWAY!". In a brief flashback, Zoro's resolute face is shown as he recalls his resolve: "EVER SINCE I'VE DECIDED TO BECOME THE WORLD'S GREATEST SWORDSMAN, I THREW AWAY MY ATTACHMENT TO LIFE." Sanji screams out loud, "IT'S SIMPLE! JUST THROW AWAY THAT AMBITION!". Zoro falls backward off the deck and plunges into the sea with a massive splash. Mihawk calmly turns around and sheathes his sword.

Johnny and Yosaku dive straight into the water after Zoro, crying "BRO!" and "DAMN IT!". Meanwhile, Luffy is consumed by rage. With his straw hat shadowing his eyes, he clenches his fist and glares at Mihawk, screaming "DAMN YOU!" as he prepares to launch an attack.

Sanji and the other Baratie cooks gasp in shock as they notice Luffy's body stretching. "WHAT'S THAT!?" Sanji exclaims. Luffy launches himself forward, stretching his arms far behind him as he flies toward Mihawk, roaring "ARGHHHHHH!". On the wreckage of his flagship, Don Krieg watches in surprise, muttering, "THAT BRAT...! HE MUST BE A DEVIL FRUIT USER!".
