Himawari Nohara, youngest in the Nohara family, enters the world on September 27, 1996. Her name, "sunflower," weaves into floral patterns decorating her outfits and toys. Though an infant, she displays a precocious, mischievous streak, driven by a fascination with glittering treasures—genuine jewels, luxury goods—which she expertly identifies and playfully pilfers. This cunning mirrors her determined pursuit of handsome strangers, echoing her mother’s habits, though cutout masks of attractive actors swiftly soothe her tantrums. Non-verbal yet expressive, her thoughts surface through subtitled gestures and actions. Remarkably agile, her rapid crawling outpaces her older brother, while the family dog, Shiro, becomes her unwitting playmate. Special manga chapters reveal her at five, mirroring her brother’s chaotic antics, wreaking havoc that tires even Shin-chan. Like him, she detests onions, sparking clashes with her mother. *Super-Dimension! The Storm Called My Bride* glimpses her at twenty as a police officer, still blushing at praise and retaining her playful charm. Her infrequent visits home spark tension with her mother. *Movie 20* reimagines her as princess of the Sunflower People, adorned in a regal gown—a reworked infant sleeper—accented with purple pearls and a tiara. Her bonds include a sibling-like tie to Masao Sato, who yearns to hear her call him "onii-chan," and Toru Kazama, viewed as a brother figure, their dynamic hinting at potential future romance. These relationships cement her role as both cherished and cheekily disruptive within her family and peers. In *Crayon Shin-chan: Explosion! The Hot Spring's Feel Good Final Battle*, she joins the Noharas in battling a bath-hating terrorist group. Though her role remains minor, her presence amplifies the family’s comedic chaos, staying true to her infant quirks without steering the plot.
