This anime takes a lot of risks by relying so heavily on exposition. It has such a rich index of lore and backstory that it ends up having to explain so many aspects in such a short time that it doesn't really do a great job of explaining them all. For example, one of my biggest questions was "does the number of legions a Solomon demon rules an indicator of how strong it is?" Or even "what's the difference between Glam Sight and Glam Sight +" (you know what I mean in EP 23.) The design on the magics and especially the Solomon demonsis PHENOMENAL, it felt all very real and easy to lower your veil of disbelief. The depth of the creative lore of this story really managed to impress me and I cannot emphasize just how much this pays off Narrative-wise.

Tldr: Great worldbuilding, phenomenal art design,

lacking in animation quality and the characters themselves can be frustrating due to their one-sided nature and their lack of complexity.
