Description
Noa Himesaka is introduced as a classmate of Hinata Hoshino and Hana Shirosaki, later advancing to sixth grade. She stands 143 cm tall with a petite build, possessing long blonde hair typically secured by a red ribbon, teal eyes, and a prominent ahoge she proudly claims as her "charm point." Her mouth resembles a cat's, a trait shared with her British mother, Emily Himesaka. She usually wears her school uniform: a navy blue dress with white sleeves and collar, brown shoes, and white ankle socks, and uses a smartphone with a pink bunny-ear case. Born on November 24, she is a Sagittarius with blood type AB and has half-English heritage. Her name, meaning "princess slope namely love," derives from "Noa" combining "from" (乃) and "love/affection" (愛), and "Himesaka" meaning "princess" (姫) and "slope/hill" (坂).

Her personality revolves around a self-assured belief in her own cuteness, frequently declaring herself "the cutest in the world," though this confidence hides underlying vulnerability. She easily becomes downhearted, especially when others, particularly Miyako Hoshino, suggest Hana Shirosaki might be cuter. Despite a bubbly and outgoing exterior, she exhibits jealousy, sensitivity to exclusion, and relies on external validation. Genuine praise, especially from Hinata Hoshino, quickly lifts her spirits; she develops a romantic crush on Hinata, leading to flustered or awkward behavior around her. To gain Hinata's attention, she meticulously chooses outfits, prepares sandwiches for outings, or becomes jealous when Hinata interacts closely with others. Intelligent and practical, Noa often provides sharp retorts to balance others' antics. She loves fashion, cute things, and herself, but dislikes things she deems uncute, aspiring to become a fashion model.

Her background involves moving next door to the Hoshino family and transferring into Hinata and Hana’s class. Early on, she witnesses Miyako Hoshino cosplaying alone and later uses this knowledge to blackmail Miyako into including her in cosplay activities. Her story shows a shift from seeking Miyako’s approval to valuing Hinata’s affirmations above all else. Key moments include dressing as Miyako to comfort Hinata during separation anxiety, receiving affectionate treatment while pretending to be someone else—an experience leaving her with lonely understanding. She grows through interactions, like nervously preparing for a "date" with Hinata and learning to navigate her jealousy. Her relationships include close friendships with Hana and Hinata, a teasing dynamic with Miyako (whom she calls "Myaa-san"), and reliance on Koko Matsumoto for fashion advice. She often organizes group activities involving costumes or stylish events.

Trivia includes her habit of singing "Atashi Kawaii Sengen" instead of counting during hide-and-seek, her strong attachment to her ahoge (becoming distressed if it's touched or threatened with cutting), and her comparison to a rabbit in an animal-themed quiz. Her full name was not initially revealed in the series but appeared in the manga’s third volume.
