Hell is divided into seven layers. The King of Hell was lost ages ago, and it has been the steward's task to sort the souls into their designated regions and maintain control of the world. Nora, the steward's stepdaughter, was an outcast, and in many ways, she still is.
After a heated argument, Nora does something inexplicable, and she soon finds herself out of the castle and in a forest with soul-eating giants. It's then that Nora meets Aegis, an immortal, who suspects Nora is more than an ordinary girl.
