I actually thought it was cool that they had a female character that wasn’t fully human-like, but alas…
To be fair, eve stands out like a sore thumb in human society, to go with touka to a major city for example, a human form probably helps.
"subhumans?"
"demihumans" or "therianthrope" might be the term ur looking for.
Demihumans are essentially humans with slight animal characteristics and are close enough to effectively be considered a human subspecies similar to racial differences, subhuman means a bipedal animal with human-like intelligence, it's not a insulting term, eve really is defined as a sub-human as she's technically a werebeast, more closer to animal than human.
Manga rarely differentiates between the 2 though.
That said i would have preferred them to just call her a werebeast.
