In such a dark and wicked environment, there appeared a devil with enough mana to attack anybody who got in her way, even if they were stronger than she was. She believes that her magic can conquer everyone, and that she would never give up until she has won and forced her opponents to succumb to their defeat. But, to her demise, she has loss to the one and only Lucifero, a high-ranking Devil, and as she flees from his grasps, despite her desire to continue their fight, but being unable to do so owing to the amount of blood she is losing, she forces her way to the human realm's gates.
