The girls doesn't feel pain and there Is no blood
Facts
I know that some girls doesn't bleed
But all of them?
take your pick
other than estia they aren't human so human logic doesn't apply
or
the dev chose not to show blood half the games i played with virgins they showed blood only upon the initial penetration then it vanished instantly as if it never happened
i personally never noticed the virgin tag though didn't look at any of them didn't care
Well I would say, Hidden are humans with abilities, they are no different from Altered or other humans in any way, at physical/biological level. So physiologically Estia, Cleos and Heramael are all having human bodies.
And again, none of them are on Earth, I am pretty sure, our planet was not born anything like collision of rocks, like told in the prologue. So none of them are really humans to start with...😅
