The thing I know about that is that she got a card from a certain Familiar I don't know who it is because it could be anyone from the school because even low rank Devils have Familiars, and she actually use the card to summon it so basically her desire was granted and she knows about the Devils.

This is actually interesting in a way because then she knows all about Issei now, and everybody else I wonder if Kiryuu would summon Issei himself.
