Even if you've never played a Disgaea game before -- heck, if you haven't played any game before -- you should watch the Disgaea 4 trailer posted below. It shows off a handful of the game's absolutely preposterous special attacks, many of which involve slamming foes into various celestial bodies.
In the beginning, man feared the darkness. Vampires, werewolves, zombies, ghosts, etc. Darkness differed by nation, but its powers were feared alike. However, as civilizations developed, people began to fear man itself, like war, murder, terrorism. This story begins at the prison of the netherworld. A story about the one who will change the world.
