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! Sugimoto and his friends head for Kushiro in order to escape Lieutenant Tsurumi’s pursuit. Meanwhile, Lieutenant Tsurumi himself leads members of the 7th Division to Otaru following rumors of the tattooed skins. Awaiting them are two of the most desperate and dangerous outlaws of the north—the Lightning Thief and his wife, the wicked Viper Ogin—and they’re both heading straight for Lieutenant Tsurumi!
