Girlfriend is portrayed as a young, mysterious woman. With a love for cherry soda and secretly you, she seems to be calm and collected in almost any situation even in the face of death. Being a demon, she seemingly possesses a great deal of power, but she chooses to hide it. 
Her lack of intelligence can result in her getting into difficult situations, such as getting her hand stuck in peanut butter jugs and having to wait for hours for someone to help get it out she is also kinda rude sometimes
