If we gonna start "nitpicking" on terminology and semantics/meanings then....
No idea why there isn't a fantasy tag because this game universe/alternate reality is fantasy, thought it had but seems not. Not important or relevant though.
The creator clearly imagined their own set of rules for this game universe, only females with 3 sub genders as female, mono futa and duplo futa. All character names are what we recall as feminine names in our reality, even when they call a deity is "goddess" and never "god". Must be hard sometimes to write always into that set of rules, some mistakes will eventually appear, that is why proofreaders exist. It would be harder in Portuguese, my primary language since we gender everything lmao.
So lets try to respect whatever the developer imagined hehe, even when we think its "wrong" for the purposes of the story/game is not wrong.
