Story
Etna awakens Laharl from a nap and informs him that he has been sleeping for two years, and that his father, the Netherworld Overlord King Krichevskoy has died. It seems that the remaining demons of the Netherworld have decided that succession should be determined by battle rather than bloodline, and have begun a war for the throne. Laharl is determined to claim his birthright and put down any challengers to his father's title.
