From T4WCWiki

Mysterious attack at enterance of Heaven, result being witnessed by Moonlightelf. After a while of frustrating waiting, the half-drow finds out that her old nemesis, elite demon Arashi, has been responsible of the act. This makes up her to set her feet into clutches of 9 floors of Hell to find and chase her to the deepest corner of Hell, preferably killing her in process. But will she succeed in her task? Or is she going to be trapped in the Hell for rest of her life, never to return to surface to see light?

The story also introduces Hell of Heirata more deeply than previous part of the saga (Heirata, Land of Gods).
