Misae Nohara is a 29-year-old homemaker and mother from Aso, Kumamoto, born Misae Koyama. She has two sisters, Masae and Musae Koyama. Her life revolves around the classical duties of a post-war Japanese housewife: cleaning, laundering, cooking, sewing, and caring for her family.
A constant challenge is getting her son, Shinnosuke, to school on time. This often results in a frantic bicycle ride after he misses the bus and was the primary motivation for her learning to drive. Her driving is poor; she frequently scratches the car while parking or has minor accidents, usually distracted by her children.
Her personality is marked by hypocrisy and double standards. She issues strict rules to her husband and children, particularly Shinnosuke, only to break them herself moments later. Quick to anger, her punishments are physical and comedic, most famously the "Guri-Guri Attack," where she drills her fist into a person's head, or delivers punches that create large, cartoonish lumps. This corrective behavior sometimes extends to a swift butt-slap for her son.
Financially, she spends very little on her husband and son's non-essentials but enjoys splurging on her daughter, Himawari, and herself. She is prone to compulsive buying, especially at bargain sales, where she purchases extreme quantities of items under the pretense of saving money, often negating any savings. She also secretly hoards money for personal use, though these stashes are frequently discovered and spent during financial emergencies. Her various diet and savings plans are all short-lived.
She exhibits jealousy and insecurity over her husband's interactions with other women, often suspecting infidelity. In these situations, she may follow him or become violent. This insecurity is partly tied to her own body dysmorphia concerning her fluctuating weight and small breasts. In secret, she harbors fantasies of dating rich, young, blonde European men, a trait inherited by her daughter. Once, after a quarrel with her husband over her spending, she attempted to forge an affair with a younger, blonde vegetable seller.
Her social life includes a close friendship with Keiko Honda, with whom she enjoys telephoning, shopping, and outdoor activities. An inability to operate computers limits her employment prospects. When she needs money, she takes part-time jobs in shopping malls, mainly at a local department store, but has difficulty retaining them due to an intermittent explosive disorder. On one occasion, she worked from home on a packaging job.
In the film "Eiga Crayon Shin-chan Bakumori! Kung-Fu Boys ~Ramen Tairan~," she and her family are affected by the Black Panda ramen incident. After her daughter Himawari consumes the ramen and becomes rageful with black bags around her eyes resembling a panda, the family is drawn into the ensuing conflict, which includes being attacked by neighbors who have joined a Black Panda ramen branch.
Her physical appearance includes dark brown hair, which she frequently changes between curly and long, shattered styles, black eyes, a height of 1.59 meters, and a weight of 72 kilograms.
