Bell-mère was a former Marine and the adoptive mother of Nami and Nojiko, introduced in a flashback during the Arlong Park Arc. She raised the two girls until she was murdered by Arlong. In her youth she was a renowned trouble maker. While her decision to join the Marines shocked all the villagers, they all cared deeply for her welfare despite the trouble that she had always given them. Due to her past, her decision to adopt her daughters led them to fear the children's own welfare. However Bell-mère was determined to show them that she had grown into a mature adult who was capable of such responsibilities. As a Marine, Bell-mère was quite confident, her reaction to Shiki's escape from Impel Down being to state that she will stop him herself should he attack the East Blue. Her fellow marines note that she is very reliable, indicating she was likely a very effective member of the Marines. Bell-mère retains some of her mischievous nature upon her return to Cocoyasi, offering to pay Genzo for Nami's thefts "with her body" (this most likely explaining where Nami got her personality from, as Nami even used the phrase when Genzo captured her, much to his frustration), despite knowing how he reacts. She occasionally acts impulsively, such as when she hits Nami for suggesting that Nojiko is not her real sister, and hits a boy for saying that her tangerines taste bad moments after Bell-mère stated to Nami she shouldn't have hit the boy. She admits that Nojiko is sometimes more mature than she is.
