One Piece Chapter 49, page 6: Storm

Zoro rests his hand on his swords, saying, "BUT WITH THIS IT LOOKS LIKE MY OWN GOAL, IS INEXTRICABLY TIED WITH GRAND LINE, CONSIDERING THAT 'THAT MAN' IS THERE AS WELL!" Sanji, smoking a cigarette, mutters, "...BUNCH OF IDIOTS. YOU LOT ARE THE TYPE TO RUSH TO THEIR DEATHS." Zoro retorts, "TRUE, BUT I'D RATHER HAVE YOU LEAVE OUT THE 'IDIOT' PART..." before declaring with absolute resolve, "EVER SINCE I'VE DECIDED TO BECOME THE WORLD'S GREATEST SWORDSMAN, I THREW AWAY MY ATTACHMENT TO LIFE. THE ONLY ONE WHO HAS THE RIGHT TO CALL ME AN IDIOT IS ME ALONE."
