My Dagger, Your Demise

To avenge my sister Alice, I, a cursed Soul Eater, married the tyrant Alpha. They thought they welcomed a helpless prey, unaware they invited a monster. Even as he risks his life to protect me, my blade won't hesitate. Now is the perfect time for revenge. I will send everyone who hurt her straight to hell. When it's all done, Alice, I'll come to you.
