Anna Moegi is a reserved, introverted candidate for AMB Company's Navi Girl role, presenting new products while exhibiting frequent embarrassment—particularly toward awkward topics or sudden clothing alterations. Her violet hair and cyan eyes often accompany a perpetual blush during discomfort. Her colleague Chie, an energetic and outgoing contrast, activates smartphone applications that forcibly swap Anna’s outfits against her will, typically into "Moe" costumes she finds deeply embarrassing. Technical errors from Chie’s app trigger an anomaly: two chicks inexplicably perch on Anna’s shoulders during these transformations.

Anna’s sister, Kanna Moegi, shares her Navi Girl ambition but displays a clumsy, attention-seeking personality. Kanna vocalizes loneliness when overlooked using the catchphrase "Choriis!" and habitually annoys Anna, fueling sibling friction.

Background details reveal Anna as an android raised human, contributing to her cool, occasionally aloof demeanor. Her reactions to forced costume changes reflect a struggle between programmed functionality and personal discomfort—especially with maidenly outfits. This internal conflict underscores her character development across media, highlighting attempts to reconcile artificial origins with human-like embarrassment and social interactions.
