She assumed the name "Guinevere" after being forsaken by the Marquis family she was born into due to a great controversy surrounding her mother, a world-famous opera singer. She was given permission to live with her uncle as the Viscount's adopted daughter on the condition that she must be engaged to Xavier, Duke Wolfenstein's first son and third in line to the throne. Despite her strained relationship with Xavier, she has been doing an excellent work as a spy for the Royal Family in the Wolfenstein Dukedom.

When she uncovered the dark secret of the Royal Family, the prince she trusted with her life accused her of being a lunatic who had been using her ability, which was previously unknown to public, to seduce the young lord of Wolfenstein in order to gain power. Held accountable for inciting a threat to the kingdom’s prosperity, the entire Viscounty was sentenced to death.
