Ozora Tsubasa, a Japanese football prodigy, forged his destiny early when a football cushioned his fall during a traffic accident, cementing his belief that "the ball is my friend." This event ignited his lifelong dedication. He practiced alone for years in baseball-dominated Tokyo, his only childhood football companion being Yayoi Aoba. Following his grandmother Hana's death, his family moved to Shizuoka's Nankatsu City to advance his opportunities. There, at age 11, he immediately challenged and scored against Shutetsu's goalkeeping prodigy Genzo Wakabayashi, sparking a lifelong rivalry and friendship. He enrolled at Nankatsu Elementary after meeting Roberto Hongo, a former Brazilian national team player and friend of his seafaring father Koudai Ozora; Roberto became his mentor. At Nankatsu, Tsubasa formed the "Golden Combi" partnership with Taro Misaki, exhibiting near-telepathic coordination. As captain of the city's all-star team, Nankatsu SC, he led them to win the national elementary championship despite setbacks against Meiwa FC, earning tournament MVP and top scorer honors while developing his signature "Drive Shoot." At Nankatsu Middle School, Tsubasa pursued a third consecutive national title ("V3"). Despite severe injuries, including a dislocated shoulder from blocking the Tachibana twins' "Skylab Hurricane," he played through pain, developing the "Miracle Drive Shot" to defeat Furano in the semifinals. The final against Toho Academy ended in a 4-4 draw, resulting in shared championship honors. Recovered, he joined Japan's junior youth team, challenged and defeated Italy's boycott with a solo goal, and eventually captained the team to win the Junior Youth World Championship. He then moved alone to Brazil to train under Roberto at São Paulo FC's youth team, befriending Pepe and facing rivals like Carlos Santana. Returning to Japan for the World Youth tournament, he led Japan to victory against nations including Brazil, scoring a hat-trick in the final. Post-tournament, he married longtime supporter Sanae Nakazawa, known since elementary school; they later had two sons, Hayate and Daibu, as depicted in the "Millennium Dream" storyline. At age 21, Tsubasa joined FC Barcelona, starting on the B-team in Spain's second division. After recording 12 goals and 11 assists, he earned promotion to the main squad. There, he learned from veteran Rivaul but initially struggled to integrate. During a critical match against Real Madrid, he faced former rival Natureza and contributed to a comeback victory after Rivaul returned from injury. As an adult, he captained Japan's Olympic and senior national teams while continuing his Barcelona career. His playing style evolved from forward to attacking midfielder ("classic number 10"), utilizing exceptional dribbling, field vision, and an ability to rapidly replicate and refine opponents' techniques. Key traits include relentless determination, leadership transforming rivals into allies, and prioritizing team objectives over personal glory, though he occasionally displays individualistic play during high-stakes challenges. His personal life remains closely tied to football, with his family appearing primarily in relation to career milestones. Statistically, his teams maintain exceptionally high win ratios across school, club, and international levels, with minimal losses throughout his career.
