Yuki, Nezara, and D'ea (Starli) (Patreon)

Before Yuki's encounter with the Palace Guards, she was trained by Nezara (left) and D'ea (right). Top-dollar slaves from Nova Dameia. They are scarcely seen near Soddorom's throne as his pride demands his own conquests surround him.

But as a Hunter's hounds soften their prey, the duo's skills are used to break in newcomers. Preparing them for the new pleasures and experiences Palace life offers. 

As the old Kaechulugg proverb goes: "Leave it to a woman to activate a woman."
