Infliction of Hellhound

There is war in the demon dimension and two sisters are brought into the conflict because their souls are not their own any longer. Casimir a demon who hardly does things for the greater good: is challenging the renowned Saffi who wishes to prove to angels that they're not all they claim to be. He's convinced that eventually the angel's anger will be directed at all the demons. Aella the heir to the throne of Angelos: after angering her already abusive parents she's forced to give her soul to a demon. Will she turn into a monster of her own kind the type she's grown up with? Deianira who fled and left her sister in the Angelos palace: finds her sister has made a deal with a demon and is filled with disgust all the while acting like the King herself. After facing the decision between death or giving her liberty away to a demon she has no choice but to give her soul away to the same one as her sister.
