Golden Kamuy’s final season is not truly final, as it still has the last volume of the manga left to be adapted. Still, if you are a fan of this series, then you will love what the final season has to offer. The final season offers more of the same, if not more. Golden Kamuy has always had great voice and sound direction, and that continues in the final season. Though the animation direction is really well done, as it uses the most of its budget, and scenes really give maximum impact.
Of course, the Golden Kamuy anime is a bit more fast-paced than the manga, but that has been a consistent thing with the adaptation. Each season improves on the previous in terms of direction. The final season has been pretty faithfully adapted. While the animation has a few episodes down the stretch where the animation reaches a low point for the season, it is not a deterrent by any means.
One thing to note before you start watching: I would recommend rewatching S3 and S4, as this season will really reward you with events that occurred in those two seasons. There are numerous twists and turns that will leave your jaw dropping, especially if you are fully aware of all these events. As it is a story with so many connected threads that is executed well, it shows the series has some outstanding deep storytelling.
This season continues to show how great of an antagonist Tsurumi is. Of course, if you watched the previous 3 seasons, that is something that you are more than aware of. The biggest thing that it shows is how great of an antagonist he is, and he isn’t purely evil compared to the majority of anime antagonists.
Do note this isn’t the end of Golden Kamuy, as the final portion of the anime will come out in winter 2027.
