After reflecting on the current state of Japanese soccer, the Japanese Football Association decides to hire the enigmatic and eccentric coach Jinpachi Ego to achieve their dream of winning the World Cup.

The sole survivor of Blue Lock will earn the right to become the national team's striker, and those who are defeated shall be banned from joining the team forever. Selected to join this risky project is Yoichi Isagi, a striker who failed to bring his high school soccer team to the national tournament.
