I can see the definitions which include the easiest interpretation of this world and the other world but I'm reading a story (very slowly and with difficulty but how else can you learn) <https://ncode.syosetu.com/n8017hi/20/> and they're currently in the other world so from their perspective would この世 just definitely mean the world of the living or would it mean the world they're currently in or could it be either contextually?
