Esther is Aunt March's French Catholic maid in the anime adaptation, hired under the condition she change her name from Estelle but retain her religious practices. She shares tales of her French upbringing with Amy March during Amy's time as Aunt March's companion. Esther introduces Amy to Catholic traditions, notably presenting a gold and ebony rosary with a cross. She clarifies its devotional purpose, contrasting Amy's initial view of it as jewelry, and advises Amy to seek solace through meditation and prayer in a private space, likening it to the comfort Esther found in her former mistress's chapel. Esther helps Amy arrange a small dressing room as a makeshift chapel, furnishing it with a borrowed Madonna painting. Acknowledging their different faiths, she supports Amy's spiritual exploration during Beth's illness. While her guidance leads to Amy's temporary engagement with Catholic practices, Amy ultimately does not adopt the rosary for Protestant prayers. Esther's role remains defined by her position in Aunt March's household, with no further background or development provided.
