Hideyoshi, a homeless boy living in near‑future New York, survives by hustling other kids in street‑ball games. He is now drafted into a professional team with a distinctive mission. Once humans dominated the sport, but the arrival of physically superior alien players has displaced them, leaving only a handful of human players. Hideyoshi’s squad, the first all‑human team to compete in the Space League, aims to reverse that trend and restore the championship to Earth.
