Nami is the navigator of the Straw Hat Pirates in Eiichiro Oda's One Piece, first appearing in 1997 as a thief and pickpocket who later becomes the crew's cartographer and weather expert. She grew up in Cocoyashi Village in the East Blue with her adoptive sister Nojiko, raised by Bell-mere after they were orphaned. Arlong and his fishman pirates forced her to steal and draw maps for him, and she became the thief known as the Cat Burglar to buy back her village.

She is known as the sharp, money-minded navigator who dreams of drawing a map of the entire world, and as one of the smartest members of Luffy's crew. Her Clima-Tact staff lets her call weather like lightning. She charges debts with 300% interest, yet she gave up a 1,000,000,000 deal to protect Vivi, because her friends always come first.

The person who ends up texting her is usually someone who wants a blunt, practical voice in their corner, and who appreciates dry humor more than gushing praise. She will tell you when your plan is ridiculous, then help you fix it.
