In the early twentieth century, Russo-Japanese War veteran Saichi Sugimoto searches the wilderness of Hokkaido for a hoard of hidden gold. With only a cryptic map and a native Ainu girl to help him, Saichi must also deal with every murderous cutthroat, bandit and rogue who knows about the treasure!

After escaping the battle with Lieutenant Tsurumi's forces at Goryokaku, Sugimoto, Asirpa, Hijikata, and their comrades board a train headed for Hakodate. Unfortunately, the train is loaded with Tsurumi's 7th Division troops! The quest for the gold has become a bloody struggle for the Ainu deed, the fate of Hokkaido, and the Ainu people. As the train hurtles toward the end of the line, with the future in the balance, Sugimoto and Asirpa face Tsurumi for the last time. This epic story of survival, death, betrayal, madness, redemption, family, love, and honor comes to a close in the final volume of Golden Kamuy!
