Hideyoshi is a homeless boy living in New York in the near future, surviving by hustling other kids in basketball games. But now he has been drafted into a pro team—a pro team with a very unique goal. There was once a time when humans dominated the game of basketball. But times have changed, and now physically superior alien players have taken over the game, with barely any human players left. However, Hideyoshi's team—the first all-human team to compete in the Space League—intends to change all that and bring the championship back home to Earth.
