Makiko is much more practical and down-to-earth than Miki. As Miki's mother, she genuinely cares about the girl, but can be quite harsh, and often loses her temper, slapping Miki around. This violence, however, is very unrealistic, and is not unlike the behavior Homer Simpson occasionally displays toward his son. It is once shown during a flashback, she was once actually quite beautiful; the stress of raising such an exasperating daughter like Miki was no doubt the cause of her current obesity. As she has Miki deliver ramen, Makiko's mantra is "Deliveries are about speed!"
