Makai Senki Disgaea: Welcome to Netherworld

魔界戦記ディスガイア 魔界への招待状

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!
