There are species who dont have males at all and are only have females. ( Parthenogenesis )
Sure its abit of a strech to call them a new species and i agree that mutants might be a better word.
But just because there are no male witches dosent mean they can't be a new species is all i wanted to say.
@HeroicPasserby
You are making a lot of assumptions there friend.
I agree that the witches are a borderline harem even if only 2 of them actually wants his attention...
Not really sure i would call it a harem if its only 2 people but anyway that's splitting hairs....
And just because you don't like the given reason for them being sterile doesn't make it any less valid.
You could easily have had a harem without the witches being sterile.
Heck even if they were sterile and he had a harem it would have had little impact on the overall story.
As for witches being a better or worse type of humanity that purelly your opinion as you clearly are getting stuck up on the sterile thing.
In truth its mainly there to give the author a reason for the witches to NOT form romantic relationships with other people and make the few that do more.... unique.
I mean it's a fantasy story anyway so you will have to have some suspension of disbelief, just because you don't like the given reasons for it doesn't make it any less logical.
