This seems well-made, but I'm a little confused about what it's going for beyond just "demon lord cool, cyberpunk cool, so what if both??"
Like, cyberpunk by its nature almost always has strong anti-capitalist themes, and some elements of the setting do point in that direction. On the other side, though, our hero is a demon lord, a role that carries with it (mostly just implied so far) monarchy/feudalism and racial hierarchy. It just seems very odd to me that they seem to be framing him as an underdog hero (from the proliferation of magic abilities and from the genocide of immortals), when his (current) goals are not really a good counter to the world's dominant ideology.
I guess what I'm trying to say is that a see a lot of questionable paths the story can take from here, and if it treads carefully I think it could be a good story, but I don't really have any reason to trust it yet. I have a friend who picked it up this season, so I think hearing about it secondhand will be enough to sate my curiosity, lol. I give the premiere a 3/5.
