Eri's mother commands the household with a firm yet cheerful authority, blending stern discipline with warm-hearted guidance. She assigns chores and corrects her daughter’s mischief—whether sneaking out or meddling with alien guests—while secretly doting on Chimpui, whom she adopts as an honorary family member despite her general dislike for pets. Oblivious to his cosmic heritage or Prince Lulealv’s proposal, she showers the alien creature with maternal affection.

Her marriage thrives on spirited debates over domestic choices, clashes softened by unwavering loyalty to their family unit. She meets door-to-door salesmen with sharper suspicion than the extraterrestrials disrupting her home, dismissing their pitches with brisk efficiency. Traditional values anchor her parenting; she frets over Eri’s fence-climbing escapades and aversion to chores, enforcing dress codes that forbid trousers—a rule rumored to stem from past mishaps. Through scoldings and secret smiles, she balances expectations of propriety with unspoken pride in her daughter’s spirited nature.
