Tetsuwan Girl

From Tsutomu Takahashi (the author of Jiraishin) comes the story of Tome Kano, a young lady who lost everything dear to her in the Second World War. She works as a waitress in a cabaret bar until, one day, she gets an offer to be part of a promotional exhibition for Girls Professional Baseball. Set on this new path, she goes on to become a legend -- the 'Iron-Armed Beauty' -- and embody the dreams of a nation.
