The phone charm ladies are the first of Yuuko's customers that appeared in xxxHOLiC Rei. They work at the same company but at different departments. They claimed the other as each one's best friend, but in reality, they hated each other. They have two identical phone charms (one shaped like a cat, the other like a rabbit) that symbolize their "friendship". Since their names weren't given in the manga, this article will refer to them as "Lady A" (the first one) and "Lady B" (the second one). The cat charm symbolizes Lady A, while the rabbit one symbolizes Lady B.
