In the underworld, known as Felicidad, humans and monsters live together in harmony. Here, farmers who breed and command monsters are known as Farmagia. Thanks to the Farmagia, the Magus Diluculum and the Magus' generals, known as Oración Seis, the society of Felicidad flourished ... until that fateful day when the Magus dies. On that day, Glaza, one of the Oración's generals, seizes the opportunity to seize power for himself.
