I guess I appreciate this character since I began to watch One Piece, 17 years ago. She is bold, knows what she wants, and gets it silently and under everyone's nose. She is a thief and a good one. Since I began playing RPG I always loved Ladins and Thieves. Her mood is something else, she can be very scared, angry, a bit manipulative, a bit greedy... but always reliable
She is someone you can certainly trust. Even if she is scared, even if she is angry at you, she will always help, always support you for whatever it may be. Nami is as passionate as the ones around her to achieve goals, hers, and her friend's.
She may get angry, she may disagree, she may not tolerate your silly and fool moments sometimes. but she always will do whatever it may be to make your dream a reality.
Nami has a sass to her. A way of being intimitating and also sexy. A way to get what she wants being cute and flirty. It can be interesting to explore it on a self-ship. She is overall cute, but she has a strong mentality and is indeed a strong female character.
