Saitama Prefecture, Shin-Koshigaya High School. Takeda Eishu, who enrolled this spring, reunited with his childhood friend Yamazaki Tamaki. In junior high school, no catcher could catch Eishu's ball, so her wildly changing "magic ball" could not be thrown, so she gave up baseball halfway. But Tamaki, who had honed her skills in a strong team, successfully caught Eishu's changeup.

The goal is the whole country! The challenge of the new Shin-Koshigaya High School Baseball Club begins here——
