Animating a sports anime like Blue Lock involves several behind-the-scenes challenges. Some of these challenges may include accurately depicting complex soccer movements and techniques, ensuring consistency in character designs and animation quality throughout the series, coordinating with the original manga creator to stay true to the source material, and managing tight production schedules to meet airing deadlines. Additionally, creating dynamic and engaging soccer matches that capture the intensity and excitement of the sport can also be a demanding task for the animation team.
