Golden Kamuy

A ship, with Lt. Koito, Tsukishima, Sugimoto and Tanigaki, arrives at Sakhalin on the trail of Kiroranke. They find Cikapasi stowed away on board, but Sugimoto and Tanigaki believe he can help them find Asirpa. While Koito visits a shop to sample local Hurep wine, they learn that Asirpa has been taken to a north Ainu village. They go after her but find another Ainu girl, Enonoka who saw Asirpa.

Sugimoto introduces himself to the large Japanese man from the Stenka audience, Maiharu Gansoku, but they speak no further. Through the tavern owner, the Japanese group is asked to throw the fight to have their dog returned, but they angrily decline. Their main opponent at the second Stenka is their target, the tattooed prisoner Gansoku.

Kiroranke's group arrives at the location of a Karafuto Ainu village where Asirpa's father Wilk was born, but they find that it was abandoned during the Russo-Japanese War and is now the location of a silver fox farm. Kiroranke and Ogata confirm that Nopperabo was Wilk and that Asirpa has knowledge that can decode the maps tattooed on the prisoners which they must carefully extract from her.

Sugimoto's group arrives in Toyohara, the centre of Karafuto, and a young boy steals a bag containing a copy of Gansoku's tattoo. Koito chases him to the Yamada Circus and the group offer to join the circus hoping publicity may let Asirpa know that Sugimoto is alive. Koito is the only one with real talent, as an acrobatic, so Sugimoto offers to perform the "harakiri" act.

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.

Kiroranke explains to Asirpa that he and Wilk were involved in the assassination of Emperor Alexander II. Meanwhile, the Russian sniper suspects that Ogata has set up a decoy and waits all night before making his move. In the morning, he sees an Uilta coffin and fires a bullet into it, suspecting that Ogata is hiding inside. However, Ogata was waiting for the Russian to reveal his position.

Sugimoto's group head north on two dog sledges but become separated in a blinding snowstorm. Sugimoto, Tanigaki, and Cikapasi reach the shoreline and they dig in to weather the storm using the dogs for warmth. Meanwhile, Koito, Ogata and Enonoka find an old lighthouse with a beacon which can be seen from a great distance. They light it up and it leads Sugimoto's group to the farmhouse.

While Sugimoto's group prepare to move on, Hijikata is near Kushiro, searching for clues to a small object which the former prisoner called Shinzo Doi, also known as "Yoichiro the Manslayer", had in Abashiri prison. His group meets an Ainu called Kiraushi who explains that the object is a "kotan", part of a male puffin's beak and he takes them to nearby Nemuro where there is a breeding colony.

Sugimoto's group get closer to Asirpa who's with Kiroranke in Ako. There Kiroranke discovers that other revolutionaries in addition to Sofia are held in the Alexandrovskaya Prison and tells the others that they could help the Ainu. In a flashback, Kiroranke, Wilk and Sofia fled to Vladivostok. There they met Koichi Hasegawa the Japanese photographer and married Fina, a local Russian woman.

Kiroranke's group obtain explosives from an abandoned lighthouse and plan to blow holes in the four walls of Ako prison. Unfortunately, only one charge works. Nevertheless, Sofia escapes and reunites with Kiroranke. She recognizes Asirpa as Wilk's daughter and tells her how Wilk convinced her that the Eastern ethnic minorities needed to unite to protect their culture and heritage.

Kiroranke and Sugimoto's groups are now near each other on the Strait of Tartary ice floe. Shiraishi is relieved to find Sugimoto still alive but is surprised to learn from him that Ogata shot Sugimoto and Nopperabo. While searching for firewood, Ogata presses Asirpa to tell him what she remembered of her father's secret code and tells her that Kiroranke arranged the murder of Nopperabo.

Kiroranke gains the upper hand in his fight with Koito, but he is shot by Tanigaki. Asirpa arrives and demands to know if he was responsible for her father's death. Unfortunately, Kiroranke dies before answering her. As Sugimoto's group cover Kiroranke's body in ice, Sugimoto tells Asirpa that before her father died, Wilk said that he did not kill the Ainu transporting the gold.
