When Lilly was a young girl, the White Dove killed her father in a White Dove raid on her village. This event had a tremendous impact on Lilly's life and personality and shaped her into the person she is. Lilly is the former middle sister, the youngest at the time being Karyn, and the oldest being Aries. However, after the death of Aries in an experiment gone wrong, left Lilly devastated and to top it off, she's become the new eldest sister with 3 new half sisters to look after. Despite her beautiful and gracious appearance, Lilly is a cynical, and prideful girl who's emotionally driven to involve herself completely in the heartache and needs of her sisters. Placing her whole heart into their affairs, as well as bearing her own heartache, she is often easily reduced to tears. Lilly has a maternal personality and acts as a motherly figure to her younger sisters.

Despite her traumatic past, Lilly still keeps her memory of when she lived in a small village until the age of 6. At that point, she and her younger sister, Karyn, were abducted by a man named Drak Kokyu (who became known later as Lord Drak the head of the White Dove cult), and taken to a strange castle in the town of "Chun De Gefokt" where she and her sisters had been raised and experimented on by the cult.

Lilly is also brutally honest, typically when she is lashing out at someone. She's clumsy, a fact she tries to hide. Lilly is insecure about herself and her abilities, and she constantly worries that she's not wanted. Her self-esteem had become severely damaged since the death of her father and the death of her older sister, Aries, leaving her unable to trust others or rely on them for support.
