I just got caught up as well, and I love how well written this story is. Like you said, you write about a lot of sensory experiences and that really helps build an atmosphere and make the setting come to life. Also, I totally ship the angels too.
The “enemy pairs” thing with and the supernatural beings spreading hope or despair to humans is really cool. I’m kind of tempted to borrow it for a Dungeons & Dragons game sometime. With credit after the reveal, of course ^_^
