A Mãe, whose name in most sources is given simply as Mama or Ms. Nuketa, is a central supporting character in the comedy anime Oraa Guzura Dado. She is the matriarch of the Nuketa family, the human household that adopts the little monster Guzura after he hatches from an egg ejected by a volcano. Her background is that of a typical Japanese housewife of the late 1960s, and her primary setting is the family home, where most of the series' humorous situations unfold. She is depicted as a consistently calm, composed, and well-coiffed woman, providing a stark contrast to her husband, Mr. Nuketa, who is described as an easily irritated office worker. Her personality is defined by her patience and her role as the stable, nurturing center of the household. While her husband often reacts with stress and frustration to Guzura's clumsy and gluttonous antics, A Mãe remains unflappable and accepting.

Her primary motivation is the well-being and harmony of her family, which includes her two children, the nerdy son Bonta and the kind daughter Susuko, as well as the adopted Guzura. She does not question the strangeness of taking a fire-breathing, metal-eating dinosaur-like monster into her home but simply adapts to the situation, fulfilling her role as caregiver. In the story, she is the maternal figure who manages the domestic sphere. She is often seen taking care of the household chores, and her interactions are largely defined by her gentle guidance of the children and her peaceful co-existence with Guzura. Her key relationships are clearly defined: she is the wife of the stressed Mr. Nuketa, the mother of Bonta and Susuko, and a surrogate mother to Guzura. While other characters like Susuko and the female dinosaur Chalala have more proactive roles in the manga, in the anime, A Mãe is a constant, grounding presence who ensures the family unit remains functional despite the chaos Guzura brings. The character undergoes no significant development or change throughout the series, as her function is to serve as a stable, unchanging anchor for the more dynamic and eccentric characters around her. Regarding notable abilities, no specific talents or powers are attributed to her beyond the typical skills of managing a household and maintaining an unshakeably patient demeanor in the face of her family's constant, cartoonish troubles.
