Isagi Yoichi is invited to Blue Lock, which seeks to train and pick the best striker out of 300 high-school forwards who can win Japan the World Cup.
The top five players in Blue Lock will play as forwards in the U-20 Cup. Those who drop out will lose the chance to play for the Japanese team.
The first selection is the round-robin tournament of five teams. But due to a special rule, the matches turn into chaotic scrambling for the ball.
Responding to Ego's urge to "take up a weapon," the players discuss what their weapons are for the matches. Isagi struggles to identify what it is.
Relying on his raw instinct of "the smell of the goal," Isagi battles Team Y's playmaker, Niko Ikki, as they "read" each other's hand on the field.
The next match is against Team W, led by the Wanima twins. Their eye contact and impeccable combinations are hard to beat.
Team Z faces an opponent who knows everything about their weapons. But they don't give up the fight, and Isagi continues to believe in himself.
