Synopsis:
This is the story of Shapiro Bosco, a member of the military group called Exilium who is in charge of fighting the anomalies called "demons" that appear in Orbis.
In one of the missions assigned to the squadron to which Bosco belongs, he encounters a strange sword (Caelesti) that emanates a mystical energy. This sword is capable of using sacred energy to absorb cursed energy. However, in this exotic mission, an evil entity appears and with great speed eliminates Bosco's entire squadron, leaving him with a wound in his arm.
Weeks later, a being who calls himself "The Curse of Orbis" appears, who together with his "Horsemen of the Apocalypse" will seek to succumb to Orbis in the midst of chaos.
