The short answer is: Yes, they do age. Like anything does.

The long answer is: Yes, they do age. But it doesn't show, like at all. So...it's something along these lines.

Their physical growth stops at one point and...well, that's kinda it. Unless you count the magic-y things that make them appear younger and whatnot, since those are apparently a thing.

' On the other hand, that one explicit motivation for human women to become Witches is eternal youth implies that it is indeed normal for most monser girls to grow old and die. '

As I said before, they all grow old in age and die...but they don't show it. Since succubus magic and all that.
