After a disastrous defeat at the 2018 World Cup, Japan's team struggles to regroup. But what's missing? An absolute Ace Striker, who can guide them to the win. The Football Association is hell-bent on creating a striker who hungers for goals and thirsts for victory, and who can be the decisive instrument in turning around a losing match...and to do so, they've gathered 300 of Japan's best and brightest youth players. Who will emerge to lead the team...and will they be able to out-muscle and out-ego everyone who stands in their way?In the second selection's "rival battles," where the winners are able to take one of the losers from their team, Isagi and Nagi have just lost Bachira to Rin Itoshi and the other top strikers. Now they have to prove the strength of their individual abilities in a fight against Shouei Barou, the top scoring player in Wing 5. If they lose, they'll be at risk of disqualification... As Isagi takes the fight to King Barou, he's aiming to end up on the side of the prodigies!
