Final Requiem is Kuja's EX Burst, where the player must repeatedly press circle to fill the gauge as Kuja performs several Flare Star attacks on his victim. If successfully filled, he'll perform Seraphic Star by zigzagging around his opponent and then ends the EX Burst with a powerful Ultima spell.
After charging up his bar, Kuja launches a red energy sphere that emits an explosion large enough to rip reality into a blue black hole and drag the pieces of reality inside before emerging in an environment resembling EX Burst in the Dissidia games. As this is going on, Kuja levitates away engulfed in purple energy and after reaching a great distance launches three white energy spheres at his opponent. Kuja then conducts various poses as various explosions occur before warping back to reality.
Requiem is a liturgical service of the Roman Catholic Church celebrated by the priest presider for the repose of the soul of a particular deceased person or persons.A
