Nao Midorikawa, a 14-year-old second-year student at Nanairogaoka Middle School, balances her role as captain of the girls’ soccer team with responsibilities as the eldest of six siblings. Her fierce protectiveness over her family fuels a strong sense of justice, culminating in her transformation into Cure March when she defends her siblings from an Akanbe attack. This act of courage awakens her powers, rooted in unyielding familial bonds. As Cure March, she commands wind-based abilities that mirror her straightforward determination, channeling superhuman speed and agility honed through athletics. Her green-themed combat attire incorporates feather and wing motifs, symbolizing her elemental affinity. Enhanced forms like Tiara Mode and Princess March introduce gold accents, angelic wings, and flowing hair, visually marking her escalating strength and resolve. Personal fears challenge her growth: a crippling phobia of insects resurfaces during a mission where shrinking traps her in an insect-dominated environment. Forced to confront her terror, she gains empathy for the creatures but retains lingering unease. Similarly, her competitive drive sometimes clashes with vulnerability, as seen when a relay race stumble costs her team victory, exposing insecurities beneath her confident exterior. Relationships shape her journey. She shares a spirited rivalry with Akane Hino (Cure Sunny), their mutual competitiveness fostering camaraderie. Childhood friend Reika Aoki (Cure Beauty) provides emotional stability, with Nao seeking solace in her calm presence. Miyuki Hoshizora (Cure Happy) admires Nao’s bravery and devotion to family, traits that inspire Miyuki to recruit her into the Pretty Cure team. In crossover narratives like *Precure All Stars New Stage: Mirai no Tomodachi*, she allies with other teams against threats like Fusion, emphasizing teamwork and wind-powered tactics consistent with her core traits. Her name, chosen by her father to embody honesty, and her March-themed identity—evoking spring’s renewal and wind’s resilience—underscore her narrative themes. Family remains her anchor, with the dread of losing her siblings driving her unwavering commitment to protect their happiness.
