Kind of the vampire/demon version of attack on titan but it works very well. Story is fascinating, in many ways - overarching plot, interactions between many different characters.

Art style is very effective, has it’s own style which is always good for a manga, like I said, amazing characters, in fact I can’t think of a single bad one, rare for anything (even those briefly seen at least look good and are memorable) and 10 for enjoyment because it is amazing in every way.

Not really something to review or critique, my advice is just to read and enjoy it, same with the side novels and of course the anime. On that note would be amazing if a season 3 could be made!
