One Piece Chapter 9, page 20-21: Chapter 9: Femme Fatale

Nami suddenly stands up, her face contorted with intense anger as she shouts, "If there's one thing in this world I really hate......it's pirates!! But I love money! And tangerines! She turns her back to Luffy, thinking to herself, "This guy's a stupid, worthless plunderer... He doesn't seem to have anything worth stealing... but maybe he could still be of use to me..." Luffy, completely unfazed, asks again, "So how 'bout it? Wanna be my navigator?" Nami snaps back, "I told you to forget about it! You no-good pirate!!" However, a devious idea strikes her, and she smirks mischievously ("SMIRK") as a pirate flag appears in her thoughts.

Nami turns back to Luffy with a sweet, manipulative smile, saying, "But you seem to really need a navigator, so I'll consider it on one condition." Luffy asks eagerly, "Really? What's your condition?" Nami holds up a finger and says, "Just a little thing. It's nothing, really. Go with me to see Buggy. Luffy, completely trusting her, grins and says, "You got it! Let's go! Where is this Buggy?" Nami tells him, "Hold on, I have to get ready." She then appears holding a thick coil of rope. Luffy asks, "What's that rope for?" Nami smiles innocently and replies, "Oh, I always carry a rope. So, you want to be a pirate, do you?"
