Sanae Nakazawa, later known as Sanae Ozora after marriage, is a central female character. Initially appearing as Sanae Nakazawa, she earns the widespread nickname "Anego" (meaning "big sister") due to her tomboyish demeanor in school. International adaptations localize her name as Haydee Amor in Latin American dubs and Patricia Gatsby in European versions. Her story begins in elementary school, where witnessing Tsubasa Ozora's passion for football sparks strong feelings for him. This motivates her to establish and lead the cheerleading club to support him and the Nankatsu team. During this time, she experiences internal conflict, briefly wishing for his defeat to prevent him leaving Japan, yet consistently supports his ambitions. In middle school, she serves as assistant manager for the Nankatsu football club alongside friend Yukari Nishimoto. Her romantic feelings deepen, particularly after Tsubasa sustains an injury during a national tournament. She intends to confess before his departure for Brazil but struggles to do so directly. This period introduces a romantic rival, Kumi Sugimoto, though Tsubasa later declines Kumi's advances. Following the Junior Youth tournament, Tsubasa acknowledges reciprocal feelings for Sanae. After confronting schoolmate Koshi Kanda, who aggressively pursues her, Tsubasa confesses his love. Sanae is the sole person present when he departs for Brazil; in some adaptations, she gifts him replacement football studs. During high school, she experiences depression due to Tsubasa's prolonged absence but continues managing the Nankatsu High team. On Yukari's advice, she works at the family restaurant Demy's to save for a trip to Brazil. Her journey to São Paulo initially results in a missed connection as Tsubasa had relocated, but they reunite before her return flight. This visit revitalizes her, and she later leads the Japan Youth supporters club during the World Youth tournament. After the tournament, Tsubasa proposes with an engagement ring, which she accepts. They marry in a Western-style ceremony attended by friends. She accompanies him to Barcelona, Spain, where he plays professionally. When Tsubasa faces demotion to the reserve team, she provides steadfast encouragement. She later announces her pregnancy, and Tsubasa dedicates a La Liga goal to her and their unborn child. During the Rising Sun arc, she is pregnant with twins. Tsubasa's team celebrates a league championship by parading the trophy past their apartment so she can participate. A character named Michael gifts her a cross, noting he "sees two angels" beside her, hinting at the twins. She returns to Japan for the birth, intending to deliver during the Madrid Olympics finals, viewing it as fateful timing. Her personality evolves from a tomboyish cheerleader with mood swings to a more feminine and supportive presence, though she retains occasional emotional fluctuations. She is characterized by dedication to supporting others' dreams, particularly Tsubasa's football career. Early jealousy toward characters like Yayoi diminishes as relationships mature. In non-manga continuities like the Tecmo game series, she remains Tsubasa's love interest and serves as manager for the Japanese national team during his professional stints in Brazil and Italy. Her name "Sanae" combines the characters for "already/early" (早) and "seedling" (苗), while her maiden surname "Nakazawa" means "middle marsh" (中沢). Trivia notes include an alternate name "Miyuki Namiki" in early anime credits and her birthday listed as April 11 in some sources.
