The Seductive Black Rabbit

Princess Cassandra kills the rabbit demon Bianca. Bianca's younger sister Nerissa comes to the royal palace to settle it, taking the shape of an ugly maid so no one will look twice at her. She works her way to King Richard, seduces him, and becomes his favorite, and she uses her demonic power to conceive several children at once without telling anyone. The Queen and Cassandra begin setting her up. Nerissa lets the trap close and then springs one of her own: the King bursts in to find her lying in a pool of blood, crying that she has lost the baby, and at that same moment Cassandra's hands start rotting from poison. The blood debt between them is only starting to come due, and the palace is not built to survive it.
