When the laws apply to people and not property, we can just start owning people as if they are property. It's really quite simple, you just need to be evil to make it work.
In Frieren's world, Demons only appear and act human as a survival trait (from what I've seen so far). In Demon Slayer, Nezuko is turned into a demon, not born one, and retains much of her humanity in staying with her brother and helping him fight other demons. I think if Frieren were to see that she was turned and not born a demon, they could come to an understanding. Frieren may even make the effort to find a way to revert Nezuko back to being a human.
For context, I've only watched the Frieren anime (not started the Manga) and only watched & read Demon Slayer through the Demon Train arc (I got burnt out and haven't picked it back up yet).
There's been a resurgence of retro gaming and collecting among millennials, so there's a few of us that do have our own Blockbuster. There's some cool collections I've seen that are set up to look like a Blockbuster store.
TV series have spoiled me with an actual storyline. Movies just seem to cram as much as they can into such little time that most of them just seem lacking to me now.
