Himawari Nohara, the infant daughter of the Nohara family, was born September 27, 1996. Her name, meaning "sunflower," frequently decorates her clothing and toys. She remains nonverbal, her thoughts conveyed solely through subtitles. Her core traits include a strong attraction to handsome young men, mirroring her mother, and a palpable lust for shiny objects like jewels and brand-name goods, demonstrating an ability to distinguish real gems from imitations. She exhibits mischievousness and high energy, often crawling rapidly and using the family dog Shiro as a toy. Like her brother, she displays food aversions, particularly disliking and refusing onions. Within the family, she embodies both adoration and annoyance, causing unintentional trouble through infantile innocence. She frequently copies her older brother's misbehavior, contributing to household chaos. Despite this, she cares for her family and spends significant time with him, though she occasionally attempts to blame him for her own mischief. Neighborhood children like Masao Sato view her as a sister figure, with Masao aspiring to be called "onii-chan" (big brother). Toru Kazama also sees her as a little sister and harbors dreams of marrying her when she grows up. In *Super-Dimension! The Storm Called My Bride*, Himawari appears as an adult police officer or secret police agent, approximately 20 years old, assisting in arrests. Her dedication leads to neglecting her family, with infrequent visits noted. She retains her signature habit of blushing and making sideways glances when receiving compliments or seeing attractive men. Her adult attire includes a yellow biker jacket, black-lined pants, green gloves, boots, and a white scarf. In *Crayon Shin-chan: Arashi o Yobu! Ora to Uchū no Princess* (Movie 20, 2012), aliens abduct the Nohara family, claiming Himawari is a legendary princess destined to save their solar system. After her brother inadvertently signs a contract allowing her to be raised in the alien world, the family embarks on a quest to retrieve her. She wears a princess variant of her sleeper outfit: a longer dress with purple pearls, an extended collar bib, and a tiara. In the 2018 film *Crayon Shin-chan: Burst Serving! Kung Fu Boys ~Ramen Rebellion~* (Movie 26), Himawari consumes contaminated "Black Panda Ramen," triggering a violent frenzy marked by dark bags under her eyes resembling a panda. Her condition motivates her brother and his friends to infiltrate the ramen factory to find a cure, highlighting her vulnerability while propelling the plot. Special manga chapters depict her as a five-year-old, developing a playful and chaotic personality akin to her brother's at that age. Her troublesome behavior challenges even her ten-year-old brother. This aligns with her established maturation trajectory while retaining core traits like mischief and attraction to valuables or handsome individuals.
