Kiku Takemoto is a supporting character in the 1981 anime, recognized as the mother of Tetsu, a friend of the main character. She is an elderly woman, approximately seventy years old, with grey hair and black eyes. Kiku, alongside her husband who is referred to as Grandpa, operates their own small business selling fried entrails, which is located not far from the establishment run by Chie's family.

In terms of personality and abilities, Kiku is a formidable and strong-willed individual. She speaks with a distinct Osaka accent and refers to herself using the pronoun watai. Her most notable trait is her immense physical strength, which surpasses that of her son. The narrative explicitly states that Tetsu inherits his combative nature from his mother, as Kiku is capable of single-handedly defeating at least four men, while Tetsu can only take on three. This detail underscores her role as a tough, no-nonsense matriarch. Her primary role in the story is defined by her relationship with her son, Tetsu, and her position as a fellow local business owner in the same neighborhood as Chie's family. No specific information about her motivations, character development, or other notable abilities is available.
