Demons ravage the land and the banners of war burn bright. Pieces of an evil Deity remain trapped below the earth in ancient, reality warping dungeons. It is a world where divine right is very real, and the social order is determined by a "class" given by God.

Such is the world that Loiel Krieger found herself reincarnated into. Or at least, that's the name she was given. Stripped of her earthly identity, forced into the body of a child and thrown into the darkness of the Dungeon without reason or explanation, she must fight to survive against impossible odds while seeking out vengeance against those who cast her down there.
