Is every human wizard a female? In both LWA series and OVA, I only saw female wizards. The most likely to be a male wizard are Lotte's dad and the magical shop owner but I never actually see them perform any magic. There are also several non-human male character like  the Dragon Fafnir, but every human male seems to be a muggle. Is there any human male wizard in LWA world? If there are none, why all of them is female?
Nope, we see a wizard who is pretty clearly male in episode 25 at timestamp 21:26. (Behind Croix, wearing glasses.)
