A tale of high adventure and survival! 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! The pursuit of the hidden Ainu gold takes Toshizo Hijikata closer to the truth about Asirpa's father...or does it? Sugimoto and Asirpa arrive in the town of Yubari just as Hokkaido glides into spring, but little do they know that their nemesis Lieutenant Tsurumi is also there with his men. Tsurumi has hired the psychotic taxidermist Yasaku Edogai in a ploy to deceive the other treasure hunters. Then Ogata, the rogue sniper, adds even more fuel to the fire when he enters the game...
