Sanae Nakazawa (later Ozora) emerges as a pivotal figure in Tsubasa Ozora’s journey, first appearing as the spirited cheerleader and manager for Nankatsu’s soccer teams. Raised in a family owning a Nankatsu ice cream parlor, her bond with Tsubasa sparks in elementary school, fueled by admiration for his relentless soccer passion—a sentiment soon deepening into romance. She spearheads the Nankatsu Middle and High School cheerleading squads, channeling her fervor into rallying support for his ambitions. Their youthful bond weathers external strains: Kumi Sugimoto’s overtures toward Tsubasa and Koshi Kanda’s persistent courtship of Sanae. Tensions peak when Tsubasa confronts Kanda, culminating in a public declaration of mutual devotion before his departure to Brazil. Determined to bridge the distance, Sanae labors at her family’s parlor to finance a Brazilian reunion, briefly reconnecting with Tsubasa before returning home. Her loyalty endures as she backs the Japan Youth team during the World Youth tournament, where Tsubasa seals their future with a proposal—offering his training ball and an engagement ring post-victory. Post-marriage, Sanae shifts to Barcelona, anchoring Tsubasa’s professional ascent. She becomes his emotional cornerstone, notably steadying him during a demotion to Barcelona’s reserves. A pregnancy with twins intertwines their personal and professional milestones; Tsubasa dedicates a pivotal La Liga goal to their unborn children. With the twins’ due date clashing with the Madrid Olympics finals, she opts to deliver in Japan while he competes, underscoring their mutual resolve. Spanning films and spin-offs like the Tecmo series, Sanae remains a constant—managing and cheering across Tsubasa’s Brazilian, Italian, and Spanish chapters. Her visual evolution mirrors her growth: anime iterations (1983, 2001, 2018) transition her from a tomboyish cheerleader with vibrant pigtails to a polished, feminine figure. Initially brash and temperamental, her persona matures into nurturing resilience, retaining the "Anego" nickname earned through her commanding cheerleading days. Bronze statues in Tokyo, depicting her mid-cheer, immortalize her legacy as an emblem of tenacity and support.
