After the Real Heiress Swapped Fates, Vengeful Ghosts Tore the Marquis's Estate Apart

I was the most vicious red-clad female ghost in Hell. When I woke, I was in a mass grave in the human world. I looked at my bloodied, battered body and tattered clothes. The warmth and heartbeat I had not felt for so long left me dazed. To bring a vengeful ghost back to life, someone would have to pay with their life and be reduced to ashes. I was startled. Who would summon me here at such a terrible cost? Then the memories of the body's original owner came flooding back. She was the legitimate daughter of a marquis's household, lost at the age of four and found again at seventeen. But her whole family favored their adopted daughter. She had been cautious and meek in the marquis's household, yet that arrogant adopted daughter still framed her and had her killed. Her parents didn't believe her, and her brothers hated her. They accused her of having an affair and beat her nearly to death with clubs before she could clear her name. Overcome with grief and rage, she finally chose to use the forbidden art she had overheard about, summoning me here. Fine. We may never have met, but if she called on me for revenge, I'll show that pack of beasts exactly what Hell is like.
