Yoichi Isagi, a first-year forward, loses his chance for the Nationals because he has passed the ball to his fellow player in front of a goal. He surely regretted it, wanting to change the flow of that game. However, fate must have another plan for him as he receives an invitation for Blue Lock. Is this the place where he can be the protagonist? It is possible. Yet, suprisingly, Isagi haven't noticed that he have taken the eyes of every strong opponent while he plays inside the cage. Can it be the hindrance of his goal to be the best striker or be his weapon against them?
