▼Director Kentaro Shima's comment▼
"I was a high school ball player in Chiba Prefecture, and it has been 20 years since I spent my youth aiming for Chiba Marine Stadium with my friends. I had a chance to direct a documentary film for The Marines. The professional baseball players I admired always thought of me as a "winner in life". However, over the past year, seeing them move forward without being rewarded for their efforts, worrying and suffering, I was reminded once again that "professional baseball players are the same people." The Marines I would be really happy if this movie reached not only the fans, but also those who have lost or failed in something."
