>Not everyone has the ability to use magic. In fact, because it depends on specific genetic factors, it could be said that not very many people at all can use it. Furthermore, the vast majority of those users are female, and it is an ability that disappears with the passing of adolescence. Because of that, young girls who can use magic are seen as ephemeral seasonal flowers, admired by young boys as idols beyond their reach, and thought of by young girls as the ideal paragon of what they want to be.

So that neatly explains why the fate of the world is in the hand of a bunch of girls but wait did we or did we not see Yoshika's mother and grandmother performing magic. Seems to me that this explaination holds no water at all anymore

In case you're wondering the quotes from the light novel which can be found partially translated here
