Captain Tsubasa is the passionate story of an elementary school student whose thoughts and dreams revolve almost entirely around the love of soccer. 11-year-old Tsubasa Oozora started playing soccer at a very young age, and while it was mostly just a recreational sport for his friends, for him, it developed into something of an obsession. In order to pursue his dream to the best of his elementary school abilities, Tsubasa moves with his mother to Nankatsu city, which is well-known for its excellent elementary school soccer teams. But although he was easily the best in his old town, Nankatsu has a lot more competition, and he will need all of his skill and talent in order to stand out from this new crowd. He encounters not only rivals, but also new friends like the pretty girl Sanae Nakazawa and the talented goalkeeper, Genzo Wakabayashi, who shares the same passion as Tsubasa, and will prove to be a treasured friend in helping him push towards his dreams. Representing Japan in the FIFA World Cup is Tsubasa’s ultimate dream, but it will take a lot more than talent to reach it.

Meanwhile, Capeta and Monami sneak into his workplace, suspecting that his father is up to something. Much to their surprise, they see a go-kart built from discarded parts—with Capeta's name attached to it! Although it lacks an engine and looks worn out, the kart is mostly complete and functional. Despite the heavy rain, Capeta cannot resist the urge to try out this new machinery.
