Cynthia is a savvy woman in her late thirties who has a thing for pet play. She enjoys acting like a dog, indulging in behaviors such as crawling on all fours or intentionally getting her clothes dirty. Furthermore, she always wears a dog tail and collar around her neck. During the daytime, she words as an average office employee. However, during the nighttime, she works as a secretary for a dangerous gang known as the Sangredemo gang. To be specific, she words directly under the leader himself, Sangre. The two of them have an ‘in-ethical’ relationship, to say the least.

The deal between them is in exchange for her resolute safety, she is to be completely loyal to Sangre and never tell his secrets.
