"Oban Star-Racers" is a science fiction anime series that blends elements of adventure, competition, and personal growth. The story centers on Eva Wei, a 15-year-old girl who, after running away from her boarding school, reunites with her estranged father, Don Wei, the manager of an intergalactic racing team. Initially unaware of her father’s identity, Eva joins his team under the alias "Molly" to compete in the Great Race of Oban, a high-stakes interplanetary competition held every 10,000 years. The race determines the fate of the universe, as the winner gains access to the Ultimate Prize, a power capable of reshaping reality.

The Great Race of Oban attracts diverse teams from across the galaxy, each representing their homeworlds and vying for the Ultimate Prize. Eva becomes the pilot of the Earth team’s star-racer, a high-tech spacecraft designed for the competition.
