Full Chapter: mangadex
The last guide chapter I can post right now. We'll have to wait until we know more and meet more of characters before I can post any more, but there is a lot of info about the cast in these chapters, that adds context to their behaviour.
I've only posted the first two pages of each chapter, as the following pages assume knowledge on a lot of later stuff, so I recommend coming back and reading that stuff once the anime is past the halfway point.
