He detects a "decease" inside his daughter

"No Rochelle, Ask for something different. Princess Tara should be used for Rok'Shar. I have some problems with Sun bitch and need divine ally" Marus never did Rok'Shar, ritual and very cruel sacrifice of a virgin to one of the evil gods. In fact he haven't planned that, but his daughter cared too much for that princess and Demon was determined to test it and judging by gray face of his daughter his worst assumptions.

"But master, Isn't Tara too valuable for that? " She asked failing to hide her fear

"One don't offer cheap stuff to gods. Besides I'll let you participate in ritual. That will be fun" Marus in his turn failed to hide his growing anger

" Master, please, no" His daughter never pleaded like that and that released Marus' anger out and he smacked succubus in her face

" How many times I said you to not get attached to your food?" He screamed

" She is not food! She is... She is my friend" His daughter answered proudly well aware that she'll get another smack. Exactly that happened

"Role of my favorite **** spoiled you. Not only you counter your master but you lie to him. Friend you say? You lived among mortals too much, you contracted their decease, love. And I will destroy the source of that decease, that little stinky princess"

Rochelle wiped her blooding lips and proudly answered " If you want to kill ones that I love, kill yourself first, father" That was the first time ever when succubus called Marus father " Or do what you plan to do with Tara, then I'll hate you forever, instead"
