For a Demon Queen, she’s sure has that “home-y” complexion. My problem to that artwork is, she doesn’t look that dignified or even smart enough to rule all the demons on the land with her intelligence. Even though they don’t follow the manga’s design, why can’t they made her eyes (at least) look a little bit aggressive instead of that “motherly” gaze?
I wonder if her character in the original LN is more gentle/softer than in the manga.
