 VOL 19: *Le Fay and Bennia will enroll in the Kuou academy while Kunou will enrol in the elementary of Kuou academy. AND... I think I read that also joined the Occult ResearI think I read that also joined the Occult Research Clubch Club..

 They are  are not normal girls .. I doubt that they do not end up being part of this special club .. Next year the club lose 3 members.

One possibility for Bennia(with le-fay already been confirmed)  more  than girls who are not part of the club ..Entering this club ... If you're a girl, you are to fall into their clutches.

 I am supporting Bennia in this comment...Tiamat? The son / daughter will have more blood than anything else dragon.
