Having both Ares and Azazel, I can say that I heavily rate Azazel. She's an incredibly powerful kamihime to have if you have the right support for her and fortunately that comes in the form of one of the "must-haves" for any wind team; Awakened Gaia. I do admit she is very hard to keep alive while leveling up since she doesn't get her regen/life drain skill til I think 55? But when she gets to max and with a decent skills rotation between her heal buff and Awakened Gaia's regen she's barely takes any damage from her Overheat DoT and gets amazing benefits that last a very long time for buffs of that kind and effectivity.
I know she doesn't have one as of yet, but I can't wait to get her Awakened form. She's a currently one of my favourite kamihime that I have just in terms of raw power she brings to a more all-rounder type element group but also in her design too.
