Watanabe Tamako is Naoko's mother, married to a frog-like husband, forming their family unit. She has curly brown hair reaching her ankles and black eyes. Her typical outfit is a green shirt, a dark apricot skirt, and yellow flats. Tamako is kind, loving, and consistently supportive, especially when Naoko faces challenges or difficulties related to her Gauko transformations. She provides assistance readily. However, she scolds Naoko for misbehavior. Tamako shows significant understanding and patience regarding Naoko's condition, including frequently being accidentally burned during Gauko's outbursts. She clearly loves her husband, reflecting a strong marriage. Personally, Tamako enjoys singing. She participates in community activities, joining a samba group. She becomes annoyed upon learning Naoko joined a rival samba team competing against her own. Tamako balances nurturing care with appropriate discipline within her family, adapting to the unusual circumstances caused by Naoko's transformations while maintaining her own interests and social participation.
