The Baseball World Cup is nearing, and Gorou Honda is eager to represent his country. However, one small problem stands in his way: the team roster has already been selected, and he is not a part of it. Nonetheless, Gorou remains adamant to join. He becomes a practice pitcher for the Japanese national team, hoping to demonstrate his incredible speed and skills to the team’s manager. Fortunately, Gorou is given the chance to prove his worth: he must show an impressive performance in the upcoming practice match involving the veteran Japanese team and the young players who hope to replace them. The World Cup will bring together some of the strongest players from around the globe. It will also set the stage for Gorou’s long-awaited showdown with his longtime rival, Joe Gibson.
