Midori Norimaki, born Midori Yamabuki, teaches middle school in Penguin Village before marrying eccentric inventor Senbei Norimaki, anchoring herself within his quirky family. Her childhood took an unexpected turn when she stowed away on a spacecraft from Planet Takeya-Saodake, leading to temporary adoption by its royal family. Though returned to Earth, she retained a dormant claim to their throne. A misunderstood proposal from Senbei sparked their romance, culminating in marriage and the arrival of their son, Turbo. Warm and patient with students, Midori’s composure occasionally fractures under classroom chaos or her husband’s eccentric experiments. Post-wedding, her demeanor softens into endearing absentmindedness, contrasting her earlier poise. Her curly blonde locks, later recolored brown, mirror Akane’s appearance—a trait leveraged for lighthearted deceptions. Beyond teaching, she navigates motherhood with gentle naivety, caring for both Turbo and Arale, Senbei’s android creation. Her story intersects with the Dragon Ball universe, sharing moments like baking for Goku and observing Arale’s clash with General Blue. The film *Dr. Slump: Hoyoyo! Space Adventure* revisits her extraterrestrial adoption, while other media highlight her domestic life. Her absence from *The Secret of Nanaba Castle* remains unaddressed.
