Nami is a navigator of the strawhats pirates from One Piece. And also the first women to join.
Nami, along with her sister Nojiko, were adopted by a former Marnie Soldier name Bell-mère and was raised in the town of Cocoyasi Village. However one day a group of pirates called The Arlong Pirates came and invade and conquer the island. Nami was then recruited by the pirates due to her amazing map designing skills.
