This martial arts fantasy features Luna as a strong, barefoot master training two male students. Though skilled, Luna has a hidden weakness—her sensitive soles, especially to feathers, tickling, licking, and nibbling. These sensations cause intense pain and played seriously, not comedically.
The Master’s soles are sensitive. The reaction varies depending on the stimulus: feathers (immobilizes her), pinwheels (a little painful), licking and biting her arch (extremely painful and she will beg and give in).
