"Blue Lock" is a manga series that follows a unique concept of challenging traditional soccer training methods by implementing innovative and competitive strategies. In the story, the clash between tradition (conventional team play and tactics) and innovation (individualistic and competitive training) is depicted through the conflict between the players' personal styles and the traditional approach to the game. The protagonist, Isagi Yoichi, seeks to revolutionize the way soccer is played by focusing on individual skills and creativity, which goes against the traditional team-oriented approach to the sport. This clash between tradition and innovation is shown through the characters' struggles, growth, and ultimately, the evolution of soccer tactics within the series.
