As someone who hasn't read the book(s) I get the feeling, that there is information missing.
There are reactions in certain scenes where I don't understand what gets the characters so excited. They act like its obvious, while it isn't for the unknowing viewer.
I have the suspicion, that there is a section in the book explaining the reaction which wasn't translated in the show sometimes.
I don't know if its true, but are the daemons all female? If so, I hope it gets explained why that is (unless I missed it).
Aside from that, great cast, great storytelling and great characters so far - Although I somehow love Marisa best so far, cunning and evil - my kind of woman :)
Similar to Usagi Drop in some ways.
