Sanae Nakazawa, who later adopts the surname Ozora upon marriage, emerges as a central female character first encountered as a spirited elementary school student in Nankatsu. Her early persona, characterized by a tomboyish attitude and natural leadership, earned her the affectionate nickname "Anego" (big sister) among peers. During this time, she first met Tsubasa Ozora, developing a profound admiration for his dedication to football. Though initial reluctance appeared in some adaptations, like accidentally hitting a friend with a ball, she quickly transformed into his most ardent supporter, founding and leading the Nankatsu cheerleading club specifically to rally behind him and his team. Progressing into middle school, Sanae transitioned into the role of assistant manager for the Nankatsu football club, steadfastly maintaining her support while navigating burgeoning romantic feelings for Tsubasa. Her relationship encountered challenges, notably a rivalry with Kumi Sugimoto, who also expressed interest in Tsubasa. Sanae struggled to confess her feelings before his departure for Brazil, though their bond deepened significantly when Tsubasa confronted Koshi Kanda, a schoolmate aggressively pursuing her. This act solidified their mutual affection, culminating in Tsubasa's heartfelt confession shortly before he left. The separation during Tsubasa's Brazilian training tested Sanae profoundly; she experienced intense loneliness and diligently saved money by working at a family restaurant to fund a visit. Their reunion in Brazil proved difficult—initially missing each other due to his relocation—but they eventually connected, rekindling their relationship. Returning to Japan, she led the Japan Youth supporters club, demonstrating renewed cheerfulness. Following the World Youth tournament, Tsubasa proposed with an engagement ring, and they married in a Western-style ceremony attended by friends. As Tsubasa's professional career advanced, Sanae relocated with him to Barcelona, Spain. She provided steadfast emotional support, notably encouraging him during his temporary demotion to the Barcelona B team. Her observant nature helped identify his struggles with performance pressure. Later, she revealed her pregnancy, with the due date coinciding with the Madrid Olympics finals, creating a poignant parallel to Tsubasa's athletic pursuits. Medical assessments confirmed she carried twins, later referenced metaphorically by the character Michael as "two angels." Across various adaptations, her personality evolved from a tomboyish figure prone to mood swings to a more composed and feminine demeanor, while retaining her determined spirit. Within the specific continuity of the Tecmo games, her storyline diverges; she remains unmarried and supports Tsubasa during his stints in Brazil and Italy solely as the Japan Youth manager, omitting the marital and pregnancy developments depicted in the manga. Her visual depiction varied: brown hair and eyes in the original 1983 anime, dark brown hair in the 2001 version, and burgundy hair in the 2018 adaptation. In the manga, her hairstyle evolved from a shoulder-length fluff to a straighter bob in later arcs. She is frequently noted for her beauty. Internationally, the character underwent name changes, such as "Haydee Amor" in Latin American dubs and "Patricia Gatsby" in European releases, though her foundational "Anego" nickname remained consistently adapted as "Patty."
