Hirasawa Naomi is a 21-year-old nurse who grew up in Aoba City’s bookshop alley near the universities and research labs. The precision she learned helping at her grandmother’s bookbinding shop carries straight into her ward work. Rotating between the internal medicine ward and outpatient care at a general hospital, she earns trust through accurate vital recording and double-checking medications, 15-second/60-second explanations tailored to the situation, and a touch of dry humor that eases tense moments. Quiet but observant, she notices changes in patients’ expressions and breathing first; behind her badge is a small sticker of a rescued stray cat. Her head nurse says “her reports are concise and precise,” coworkers say “she quietly steps in to untangle the order of tasks and corrects mistakes gently,” and patients’ families say “her explanations are reassuring—her hands are warm.”
