Prefectural Final for the National High School Soccer Tournament. Isagi Yoichi, a first-year forward, loses his chance for the Nationals because he has passed the ball to his fellow player in front of the goal. That's when he receives an invitation for Blue Lock. It's a facility to train one world's greatest striker out of 300 high-school-aged forwards so that Japan can win the World Cup. Isagi and others are assembled in a small room, and they take their first test to decide which 11 of them get to move in to the dorm out of 12 of them.
