In 1925, during the 14th year of the Taisho era, baseball was still barely known in Japan and only a handful of male teams existed. When a baseball player tells a girl that women should become housewives instead of pursuing education, 14‑year‑old Akiko decides to prove him wrong. She invites her friend Koume to form a girls’ baseball team, challenging the notion that baseball is “what the boys do.” Even running was considered too vulgar for women at the time, so the girls face many obstacles: recruiting enough members, securing permission from their parents, and learning the fundamentals of the sport, which proves to be more difficult than they had expected.
