- Accidentally Correct Writing: Wilk raised his only child, Asirpa, to be a huntress, which is unusual because Ainu culture strictly enforced gender roles. However, as the series' Ainu language supervisor, Nakagawa Hiroshi, states in the seventh chapter of Ainu Bunka de Yomitoku Golden Kamuy ("Reading and Understanding Ainu Culture: Golden Kamuy"), Mokottunasi Kitahara discovered not only that there was an Ainu story about a girl raised as a skilled huntress in her murdered older brothers' place but also that Kinsei Ezo Jinbutsushi ("Personages of Early Modern Ezo") by Takeshiro Matsuhara documented a real-life Ainu huntress named Ciyuhirika.
- Acting for Two: The Japanese version has the Nikaidou brothers voiced by Tomokazu Sugita. Averted (so far) in the English version, where Stephen Fu is Youhei and Stephen Sanders is Kouhei.
- Doing It for the Art:
- Executive Meddling: The director of the anime adaptation, Hitoshi Nanba, explains on Twitter that when given the plan to animate the series, he was told to omit Shiton Anehata because the episodes involving the character in question contain bestiality and animal slaughter.
- Playing Against Type: Both Sayaka Ohara and Terri Doty as Kano Ienaga, a seemingly nice woman who happens to be a serial killer and formerly a man.
