It seems that there has been an unexpected turn of events in the Netherworld. The angel assassin-in-training Flonne, who was on a quest to destroy the demon Overlord, accidentally woke Laharl, the demon lord and heir to the throne, from his two year slumber. Now, Laharl, along with his not-so-faithful vassal Etna and her army of explosive souls in penguin costumes, must restore order to the crumbling Netherworld. This is based on the events of the game Disgaea: Hour of Darkness. The story follows Laharl's journey to squash the demon rebellion, reclaim the throne, and destroy anyone who stands in his path. However, it's important to note that Laharl is a demon lord and may not show kindness, compassion, or love towards others.
