Riliane Lucifen d'Autriche was the last Princess of the Kingdom of Lucifenia, regarded as The Daughter of Evil, and the twin sister of Prince Alexiel. Separated from her twin in a political dispute during childhood, Riliane grew up in a lavish lifestyle, ignorant of her past. The selfish Princess was unknowingly possessed by the Demon of Pride and, after her mother's death, became Lucifenia's monarch. An arrogant tyrant, Riliane became despised for her terrible regime, aided by her loyal servant, Allen, in exterminating any opposition.
