Blame! Movie, Shoujo Shuumatsu Ryokou Recommendations
Huge uninhabitant city/world that was build way in the past. This anime is way more calm but if you enjoy just the dystopic feeling this anime might be something for you.
Both stories involve a pair moving through an apocalyptic world, they don't explain the cause of the Apocalypse but instead show how the characters live through it, where they learn and craft their own journey. Blame! differs being a hardcore violent cyberpunk built around the idea of escapism. While Girls' Last Tour is a much gentler iyashikei anime that goes to focus more on the characters interaction with the world as they learn and discover things of the past. Overall, if your looking for a story built from a journey through an apocalyptic world, you will likely enjoy both series.
