Makai Senki Disgaea

Japanese Title: 魔界戦記ディスガイア

English Title: Netherworld Battle Chronicle: Disgaea

Plot
From the darkest realms of another dimension emerges the story of Laharl, the son of a demon overlord, and his two sidekicks: his impish servant and an angelic assassin. Awoken from a two-year, poison-induced nap, Laharl learns of his father's demise and blazes a trail of destruction on his quest to declare rule over the Netherworld. Never skimping on the wisecracks, the diabolical prince and his accomplices battle dragons, sorceresses, robots, power-hungry humans, and corrupt angels.

Based on the popular adventure games, Disgaea lunges at you with a full-force attack. You can laugh, cry, scream or squirm, but you can't escape the wrath of Laharl, dood!

Second Season Trailer: Makai Senki Disgaea: Welcome to Netherworld
A unique trailer found on both the DVDs and on the Disgaea 2 game advertising the anime. The animation for it is completely new, none is recycled from the show itself. Does a decent job of introducing the major characters and general plot, with new battle scenes and an altered plot so as to not give everything away. There's even a boom in shot at one point!
