Makai Senki Disgaea (Netherworld Battle Chronicle: Disgaea) features Laharl, the son of the late Overlord, Etna, his "loyal" vassal, and Flonne, the love-obsessed Angel Trainee, as they traverse the Netherworld in an effort to help Laharl claim his rightful position as Overlord. However, Laharl isn't your typical everyday hero. He's a demon who can't stand love, justice, or sexy women. Along the way the way they encounter the Earth Defense Force, who pose an annoyance to the prince, Vyers (Mid-boss), the steppingstone in Laharl's trek to Overlord, and several assassins who seek Laharl's life. Then there's the Prinnies, the penguin-like demons whose stupidity increases the comedic value of the show.
All in all, Disgaea is a funny show with a decent amount of action and drama in it. I strongly recommend it to any anime fan looking for a laugh.
