Disgaea D2: A Brighter Darkness

Prince Laharl has now become the Overlord of his own Netherworld, but is lacking charisma to gather many vassals and be recognized as such. The Krichevskoy Group, a gathering of Laharl's late father's former vassals opposes Laharl's Overlordship. When Yuie, flowers native to the angel's realm Celestia start appearing in Laharl's Netherworld, strange events affecting demons start occurring. (Mobygames)
