Well her identity is supossed to be revealed next volume. To me she is certainly a desendant of Lucifer and Lilith if ya think about it. Needs to hide her face in public, no other character has done that and with being a descendant of Lucifer where all except Vali have been total dicks, yeah not many people would be too happy about seeing her and since she is hiding her face that means people knows what she looks like so it is dangerous for her. I think she joined Issei's peerage to see her nephew Vali who Vali does not know about to give him a 'family' he never had. If i am right then give me all your Blue Eyes White Dragons lol
