Bakabon's mother acts as the maternal figure in her family, dedicated to managing household affairs as a homemaker. She graduated from Kuroyuri Women's University before marrying. Her traditional responsibilities encompass cleaning, cooking, and childcare, performed while wearing a headband and apron typical of a Japanese housewife.

Despite frequent disruptions from her husband and son, she upholds familial stability through nurturing and emotional support. Her characterization blends strict discipline with underlying affection; she often scolds misbehavior yet fundamentally prioritizes her family's wellbeing. This duality appears in her resourceful problem-solving using household items during crises.

Interactions with recurring characters reveal specific traits. Confrontations with Non-chan, a pretentious former classmate, trigger assertiveness beyond her domestic role. These moments show her capacity for direct confrontation when traditional values are challenged, exemplified by an incident where she forcefully ejected Non-chan from the house following excessive boasting.

Her portrayal remains consistent across media adaptations, including the 2015 crossover film where she plays a peripheral role to central plot developments involving other family members. Her narrative function centers on providing domestic stability against chaotic family dynamics, with no significant backstory expansion or personal evolution documented in available sources.
