An extra character became a villainess

### Prologue

Born to a half-witch mother and an archmage father, she was blessed with an abundance of mana. At the age of eight, her family was brutally murdered by unknown assailants, leaving her as the sole survivor. Consumed by rage, she vowed to avenge their deaths. "Mom, Dad, Sister. I will avenge you, no matter what."

While honing her skills in magic and swordsmanship, she discovered her unparalleled magical power. However, despite her vast mana reserves, using her powers left her utterly exhausted. To survive, she became the youngest assassin in the Lavastian Empire, tasked with eliminating traitors and stealing five gold pieces weekly.

Her life took an unexpected turn when the Duke and Duchess Flowell, unable to have children, adopted her. For four years, she experienced the warmth of a loving family until tragedy struck again. The Flowells died in a carriage accident, their bodies unidentifiable. An investigation revealed they were killed by bandits, reigniting her fury and resolve for vengeance.

Resuming her lethal path, she became known as the "Dark Killer" in the Cevallos Empire, always donning a black mask and cloak on her missions. Amidst her quest to find her families' murderers, she encountered the affection of several male leads.

"As I thought, this world I live in is a fantasy romance novel."

Meeting one of the male leads triggered memories of her previous life, a novel she had read before being reincarnated. This revelation marked the beginning of the story 'Flattering Blossom Fantasy Romance'.
