Yaag Rosch

Lieutenant Colonel Yaag Rosch is a PSICOM officer and a major antagonist in Final Fantasy XIII. Though he had a hard time in the military academy, he graduated second in his class, just behind Jihl Nabaat, later becoming her right-hand man and the Director of PSICOM's elite division.

Rosch devotes the entirety of his life and career to the betterment of Cocoon and the protection of its citizens, and sees submission to fal'Cie guidance as being in humanity's best interest, even though their "benevolence" turned out to be a farce.
