In the future, humanity has developed a multi-sport tournament known as the Iron League, in which the players are AI-powered robots instead of humans. The competition is wildly popular. However, its main support comes from the Dark Organization, a group that produces cheating Iron League members who use dirty and violent tactics in games as a sure ticket to fame and popularity. While the sports community has devolved into a dangerous and bloody competition, Silver Castle, the team with the lowest winning percentage, attempts to preserve the true spirit of sports by playing sports according to their original rules without cheating or violence. The fate of the team, as well as that of the Iron League itself, changes when two Iron League members (Mach Windy, the former star striker of Dark Prince FC and Magnum Ace, a mysterious but skilled baseball player) join Silver Castle and slowly lead the team back to its forgotten glory. However, it's not all fun and games; As the story progresses, it is revealed that the Iron League is actually a front for something far more sinister...
