Liese Luvens

Overbearing, arrogant, and will stop at nothing to achieve her goals. She used to be pure like Tita, but the succession to thrones has distorted her personality to the point where she hates Tita.
For better or worse, she is more human than Tita, and thus more prone to flaws and mistakes.
Although she keeps others at arms length, she has a secret desire to be accepted by someone for who she is.
She first hired the protagonist and is treated like a client, but he only sees her as someone to take revenge on, and she too is raped and humiliated like Tita.
Furthermore, as her training progresses, she becomes dependent on the protagonist, who has been rejecting others for years, and wants to be spoiled by him.
