In Felicidad, farmers known as the Farmagia raise monsters under the peaceful rule of the Magus Diluculum. After the Magus passes, a power struggle erupts among forces using monsters to seize control. In the town of Centvelt, Farmagia Ten and his friends band together against the despotic new ruler, Glaza. Ten, his friends, and their home-grown monsters must stay strong to defend their freedom.
To defeat Manas, Ten, Leii, and Arche infiltrate Perfectus as an elite strike team, aiming for the castle. During their mission, they reunite with their missing comrade, Emero. While Ten is overjoyed by the reunion, Emero gazes at them with a stern expression and utters a chilling remark.
