Demeter is the Goddess of Harvest. She currently lives in the mortal world bringing spring to mortals. She is a member of the 6 Traitors Dynasty and the owner of Barley Mother.

Through the perspective of her daughter and friends, Demeter is described as an overbearing mother. She doesn't allow Persephone a phone, encourages her to train to be a sacred virgin and frequently photographs every moment of Persephone's life. Despite this, her relationship with her daughter is close. Persephone is often quoting her advise and verses through out the comic. According to Persephone, her mother encourages her to earn her own fiance if one chooses to live on their own. This indicates Demeter is a hard working person. She has been described by Hades to have been the contrarian of the Six Traitors.
