Raskreia is definitely a dominatrix, what's sad is that her going and hearing her father ask that to Raizel... since we all know Raizel never ever wanted to become lord. Also Raskreia know's pretty much nothing about Raizel... other than that he is the Noblesse and a rival in her eyes... So all out of her jealousy that her father asked Raizel if he would even think of becoming Lord she is destroying Lukedonia.
and of course she believe Raizel betrayed.. and killed her father... which obviously makes her want to do anything she can to make Raizel suffer and bow to her, to prove that she is better than him and the one and only LORD... tho Raizel even has Ragnarok now...(not sure if he grabbed it or not but yeah) love that the former Union members came along, now known as RK-4.
