Plot Synopsis by AsianWiki Staff ©
In 1994, a human skeleton is found in the mountain of Saitama. A shogi game piece is found with the skeleton. The shogi piece was made by a master craftsman. Veteran detective Takeshi (Kohei Otomo) and rookie detective Naoya (Misako Renbutsu) begin to investigate the owner of the shogi piece.
Keisuke (Yudai Chiba) is a genius professional shogi player. While doing an interview with a shogi magazine, Keisuke recalls his childhood. In 1972, Keisuke was an elementary school student and he lived with his father. His father was violent and did not even give Keisuke a proper meal. Keisuke happened to meet Koichiro (Akira Emoto), who was a retired teacher. Koichiro was nice to Keisuke and, because of him, Keisuke became fascinated with the game of shogi.
