A homeless kid who beats other kids at street basketball gets drafted to save humanity from alien dominance in a sport that stopped being theirs. The show never flinches away from how impossible this is, your team is outmatched, outphysicaled, and playing against species that were literally built to win. Every possession matters because there is no margin for error when you're fighting extinction with a basketball. Hideyoshi doesn't have the gift; he has hunger, and that turns out to be the only thing aliens can't replicate. This is what happens when you put a street hustler in a uniform and ask him to be a symbol he never wanted to be. The ball doesn't care where you came from.
Hideyoshi is a homeless 14-year-old in near-future New York who gets by hustling other kids in street basketball games. Basketball has become the most popular sport in the universe, but its top professional circuit, the Space League, is ruled by physically superior alien players, and almost no humans remain. An old man named Yoshimune believes humans should be number one again. He sets out to assemble the best all-human team he can find. His scout Cha-che approaches Hideyoshi with an offer to join, and the boy's absolute self-confidence is exactly what Yoshimune wants. The team becomes the first all-human squad to compete in the league, aiming to bring the championship back to Earth and to take on Gyuma, the 19-year-old widely regarded as the best player in the game. The result is a sports story with a sci-fi setting, built around underdogs facing alien competition on the court.
