Golden Kamuy is a series about a Russo-Japanese War veteran searching for a secret hoard of Ainu gold in the harshly beautiful Hokkaido wilderness with an Ainu girl for a guide. This treasure hunting story has the feel of a Western (since this is set in Hokkaido, an eastern northern?), frontier life, renegade soldiers, escaped convicts, indigenous survivalist, and lost gold. The story is briskly paced, one chapter in, and the duo are already looking for pieces of the map to the hoard.
The characters are also well developed. Asirpa the Ainu is a skilled hunter, that a former soldier named Sugimoto the Immortal looks up to her in awe, and with a name like that, he's no pushover himself. The first time they meet, she ends up saving him from a massive bear looking to snack on his tender entrails.
The story itself has a veneer of realism that can only be achieved by extensive background research, and the author supports this with a list of references as an appendix and even cites an Ainu language consultant. This is important because one of the charms of this series is the detailed depiction of Ainu hunting culture and the flora and fauna of the region.
This is truly an excellent first volume because now I want to know if our intrepid treasure hunters will even behold the gold in the end.
