Books like Golden Kamuy, Vol. 1

A tale of high adventure and survival on the Japanese frontier! In the early 20th century, Russo-Japanese War veteran Saichi Sugimoto searches the wilderness of the Japanese frontier 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! Immortal Sugimoto, a survivor of the assault on 203 Meter Hill during the Russo-Japanese War, now scratches out a meager existence in the post-war gold rush in the wild frontier of Hokkaido. A chance encounter in the woods puts a map to a hidden fortune of Ainu gold in his hands, but Sugimoto is not the only interested party, and everyone who knows about the gold will kill to possess it!
