Kazuko Saotome is the wife of Dr. Saotome and mother to their three children: Tatsuhito, Michiru, and Genki. She deeply supports her family and welcomes the Getter Team members as extended family, frequently sharing meals with them during peaceful moments. A profound trauma, rooted in the loss of her parents during a wartime airstrike, fuels her strong aversion to weapons and violence. Witnessing battles can trigger this trauma, causing her emotional distress. Her opposition to weapon development creates ongoing tension with Dr. Saotome, who is forced to convert the Getter Robo—initially intended for space exploration—into a combat machine against the Dinosaur Empire. Despite her fears and personal convictions, Kazuko reluctantly accepts the necessity of her family's involvement in the conflict, permitting them to fight while enduring her own anxieties. Her background consistently emphasizes familial bonds and the psychological toll of war, with her role primarily focused on maintaining support within the household and institute. Information beyond the original series context remains unspecified.
