Female Ziegevolk and male Musai could exist, simply they use their powers to opposite gender or only male Ziegevolk and female Musai use their powers and their counteparts do not do nothing with them. Both teories are probable.

I don't see any problem with male Seltenvogel, he probably also produce Unbezahlbar.
