The War To End All Wars was only the first World War, but the changes it made to the countries involved were staggering. In 1925, one year into the reign of Emperor Hirohito, Japan is re-inventing itself. The national pastime, baseball, however, remains exclusively the domain of males. Until an arrogant local player sneers that girls should become housewives rather than attending school, and teenage firebrands Koume and Akiko respond with the shocking move of forming their own baseball team! It's as scandalous as the new sailor suit school uniforms, but in a nation in which almost anything now seems possible, it may just be the start of something greater than any nine girls can imagine in TAISHO BASEBALL GIRLS!
