Fate/Light

Fourteen years after the events of the Fifth Holy Grail War, another war is about to begin and the center to this war is 22 year old Akiara Mehta. Akiara didn't know much about the grail war and the role mages play until she meets Ruler class servant, Jeanne D'Arc, who prepares her for the war and for her true servent, Archer. Unknown to Akiara, she harbors something called the Darkness that her family has been sealing for the past 264 years, back to the first grail war. Not only does she have to participate in the war, but she has to keep the Darkness sealed in her or else it will be the end of her and the world.
