Sylpha, a guardian of the forest, fights and is defeated by a mysterious man who attacks an elven village and steals its treasure. Humiliated and with a lewd crest on her abdomen, her body is consumed by pleasure every day.

However, Sylpha's body continues to be at the mercy of the pleasure of the crest.... What will be Sylpha's fate? (Source: showten, translated)
