The ExWire of True Cross Academy are beset with shock and fear in the aftermath of discovering that one of their own classmates, Rin Okumura, is the son of Satan. But for the moment, they have more pressing concerns than that of Rin's parentage: the left eye of the Impure King, a powerful demon, has been stolen from the academy's Deep Keep. After an attempt is made to steal the right eye in Kyoto as well, Rin and the other ExWires are sent to investigate the mystery behind the Impure King and the ultimate goal of the thief.

While this mission has them cooperating for the time being, Rin has never felt more distant from his fellow exorcists. In his attempt to reconcile with them, he undergoes specialized training to control his dark power. However, when the right eye is stolen not long after their arrival, the unthinkable threat of a traitor amongst them leaves them in need of all the power they can get.

Final Fantasy XV takes place on the fictional world of Eos. All the world's countries, bar the kingdom of Lucis, are under the dominion of the empire of Niflheim. Noctis Lucis Caelum, heir to the Lucian throne, goes on a quest to retake his homeland and its magical Crystal after it is seized by Niflheim on the eve of peace negotiations between the two nations. However, he soon discovers that the Crystal is at the heart of a much greater threat to Eos, and that his role as the future king is key to averting an apocalyptic event from taking place. The game shares a thematic connection with Fabula Nova Crystallis Final Fantasy, a subseries of games linked by a common mythos which includes Final Fantasy XIII and Final Fantasy Type-0.
