Calev and his friends face new enemies over the fortress-type giant weapon "Deus ex machina" excavated from the great desert. The name of the enemy was Versus Grisvane-the general general of the continent's strongest nation, the Tidaros Federation, and a "transcendent" with an unknown D materia. Calev confronts Versus with the mystery of killing his life in order to protect his dear companion, but he suffers a defeat in front of Versus's mighty power. The third heatful fantasy that returns the chaos of the turbulent world to ashes with the flames of a demon!
