Golden Kamuy 3rd Season

Synopsis

Kiroranke's group had travelled much further north on Sakhalin than Sugimoto believed, and were at near the Russian border although low on supplies. Ogata shoots a reindeer from an Uilta’s herd and they are told by the herdsman that they must replace it[e]. The group go hunting with the herdsman and his son, and when they find a wild herd, Ogata shoots all the reindeer, providing the Uilta with an abundance of food and skins. It is revealed that this is part of Kiroranke's plan to befriend the Uilta and enlist their aid to travel across the border into Russia. Back in Otaru, Tsurumi reveals to Nikaidou that Kiroranke was a teenage member of the group responsible for the assassination of Emperor Alexander II in Russia, and he leaked information to the Russians that Kiroranke was on his way into Russian Sakhalin. Just as Kiroranke's group cross the border disguised as Uilta, a Russian sniper shoots the old Uilta who is carrying Ogata's Japanese rifle. They realize it is an ambush and Ogata manages to shoot the Russian commander, giving them an opportunity to reach the safety of the forest. The wounded commander reveals that Kiroranke's identity has been circulated among Russian troops. Meanwhile, a deadly game of cat and mouse begins between Ogata and the Russian sniper.
