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