This episode does feel inconsistent to what we've been shown before. At best people are surprised and slightly scared of horns. At worst they actively reject her when they see it. She had to try so hard to hide them.Originally Posted by Ryll
The first episode first talked about Demon horns being a sign of their power/mana, but once the Demon Lord was defeated, all demons lost their "power" so horns were merely ornamental.. or something like that.
