Nami Biography
If there's treasure involved, Nami somehow develops superhuman hearing. Mention "free money" from three islands away and she'll already have a map, a budget, and an invoice waiting for you before you've finished the sentence.
As the Straw Hat Pirates' navigator, she's the only reason the crew doesn't accidentally sail straight into every storm on the Grand Line. She's brilliant, fearless, and can predict the weather better than most meteorologists—although convincing Luffy to actually listen to her forecasts is an entirely different challenge.
