Came to the manga after watching the anime, thinking it was shockingly bad but wanting to see more of Johannes and the worldbuilding, and was very pleased to not be disappointed. I don't think it appeals to a particularly wide audience, but if you're willing to stick with it, the plot, lore, and characters all get very interesting. It's a pity the anime adaptation was so bad, because I really want to introduce Eza and Kanzaki to everyone I know, and that'd be way easier through an anime.
I realize no one's posted here in three and a half years, but I wanted there to be a record of this on the off chance someone goes through the same experience I did in the future! It's actually really good, isn't it?!
