There is a rumored stash of hidden gold in Hokkaido, allegedly stolen from the original Ainu owners by a man who killed them. Before being caught and imprisoned, he supposedly hid the gold in a secret location and tattooed a map of the spot on his cellmates' bodies as a means of communication to his comrades outside. Promising them a share of the treasure, he encouraged them to find it after escaping. In Golden Kamuy 2nd Season, First Lieutenant Tokushirou Tsurumi aims to give the 7th Division an advantage in the hunt for the tattoos. He plans to have a taxidermist create fake skins that only he can identify as such. Meanwhile, Saichi "The Immortal" Sugimoto, Asirpa, and their companions pursue a strange rumor about a thief who broke into a home in Yubari and discovered human corpses that had been taxidermied, including one with peculiar tattoos. Their search for the skins continues.
