Alright. Here's a conspiracy theory: What if in this world, only males exist as humans while females exist but as monsters, eg. the red-head banshee; and there's been mention of a 'witch tear'(although it was a fruit). Hence the lack of women characters. Or.. Conspiracy theory #2: This world is heavily(emphasis on heavily) patriarchal and women are treated as nothing but breeding property/slaves? Hence the lack of notable female characters.
