Ann is a young girl with short light blue hair topped by a pink clip, and light blue eyes. She is wearing a white shirt with short sleeves and aqua green stripes and a light blue skirt with white lines.
She was Oda's second attempt at a Nami-like character and, unlike Silk, there were no signs that Oda had any intention to make Ann join in Luffy's adventures. Her background was farther from Nami's than Silk's, with no mention of parentage at all. Once again, Ann's hometown was the target of pirates—however, unlike Silk and Nami, she was the only person left alive.
Personality wise, she has Nami's hot temper and impatience for Luffy and was constantly complaining about his actions. This was brought out further by Luffy displaying more stupidity in Romance V.2 than in the final version.
The voice actress for Ann in Episode 907 is Nami's voice actress.
