Ann is a member of the Oni race who serves as the head maid in the community, taking on significant authority and responsibility in managing the household and domestic duties for the village leader, Hiraku. She maintains a composed and professional demeanor in her daily interactions, but beneath this stoic exterior lies a forceful and assertive personality. When disputes among other residents drag on too long, she intervenes directly, using her overwhelming physical strength to subdue the participants in seconds. Her no-nonsense approach to conflict resolution leaves little room for argument, and she is known for her determined, unyielding presence. Ann becomes one of Hiraku’s wives and is deeply involved in childcare, helping to deliver his first child and later giving birth to children of her own. She also serves as a personal maid to Lu Lucy, whose messy habits she openly criticizes. Her dedication to order extends to all aspects of village life, and she remains consistently forceful in maintaining discipline, whether in domestic management or at martial events.
