Angelica, the ancestral "Vampire Princess of the Fallen Kingdom," as she is known, will destroy a kingdom with her magic today. The reason why— "Ma… ma…" It's all for the sake of her too-cute daughter! When Angelica found a human baby abandoned in the forest, she brought her home. She was immediately fascinated by the baby's soft, plump skin and her pure, undefiled heart, and a ruthless killer became a loving mother. But one day, the King foolishly tries to kidnap Angelica daughter, whom she named Pearl, because of her special power as a "saint." Naturally, Angelica is furious! The word "mercy" no longer exists in her vocabulary, as “Mama” will use any means at her disposal to destroy her enemies! The most powerful vampire princess will go on a rampage out of love! A dark fantasy about a doting mother! (Source: TO Books)
