2015 marks the first time that a Shogi game software is played against a professional human player. Riku, a talented young professional, is not afraid of the risk of losing to a computer and offered to play against it. What he doesn`t know is that the software`s developer is Eiichi, who was once a fellow student at an institute for boys training to become professionals. Why the young Eiichi gave up on his dream of becoming a professional and instead became a shogi software developer is a mystery. Inspired by a true story, this moving coming-of-age film is not just about a game between an AI and a human, but also about a fateful battle between two rivals, and the hard work that each of them had gone through to get there.
