Where is Nami from?

She's from the ocean. She's listed as independent, she's not from any of the established cities

shes from de ocean and travel to every place trying to find the moon stone, i think she has been in bilgewater (the butechers bride merchant says "Hi, Nami. Still sorry about that whole 'net' incident) and she previously was friends with fizz .so i guess she stayed a lot of time in bilgewater

i thought she was from the sea my whole life was a lie
