Chieri was created to be the source of relief for the males of a town placed under curse that caused them to become incredibly degenerate and aggressive until they needed to act on their dark desires. After their "release" they would revert to their normal selves. Chieri took great pride in her job feeling herself to be a protector of the women of her village by taking all the abuse that would otherwise be directed at them. Her creator made her incredibly resistant to physical pain and damage. He also gave her the ability to reform her body at will, so she could fulfill her clients darkest desires. She performed her duty happily for years until an adventurer came though and was able to remove the curse. She was told she was no longer needed in the town, and with her loss of purpose she grew angry at the traveler and his companions. She vowed revenge and shortly after met The Rogues whom she quickly joined.
