Gurung Baela" is a work depicting the struggle of the devil maid Margula, set in the devil world. Despite the fact that most demons have brown skin, Margula is naturally fair and worried that "the skin may be white due to lack of magic." One day, Marugula finds that Duke Lurubekia, who has beautiful dark-skinned skin, has put up a job advertisement with a "chore request". She hopes that if she is near a duke with high magic, she will be blackened by her magic.
