Hell Kitty Lashing Out

Tina carries a destructive power inside her that she has to keep sealed, and the one thing that holds her together is her dog Aki. To stay hidden she marries into the Hale family of Cloudmere under a false name. The marriage turns into years of humiliation and beating at the hands of her husband, and she takes it, because leaving would mean being found. Her husband works out what the dog is to her and kills Aki to bring her to heel. The seal breaks. She stops absorbing what the Hales do to her and starts pulling apart the family's standing in the city piece by piece. Her bodyguard, who has said little the whole time, turns out to be the head of a conglomerate and has been there only to protect her.
