Honestly, this OVA answers a lot of loose ends that you might come across watching the first season. The Story is told to us in three parts and there is a bit of a time skip in between some of the parts but for anyone who is watching Golden Kamuy I feel like this OVA is a must watch as it shows us a lot more hilarious scenes with Shiraishi and also goes in on what happened during the horse races. This is a must-watch if I do say so myself and it really lives up to the reputation Golden Kamuy has.
