The bad news: It is TERRIBLE. One of the Disgaea demons decides to take over the human world and Laharl (who may or may not be Overlord) cannot let this stand, because if anyone is going to take over the humans, it's him. So he takes Etna to get the rogue demon back, and Etna keeps trying to assassinate Laharl, as is her way. And Azula and Toph (and possibly June) are the only people who can stop ALL of them. (For the Disgaea definition of "stop," which is "have some jerks you don't like force themselves onto your team.") Then, if Laharl isn't Overlord, they all go to kill his dad and, thus, shatter Disgaea canon into pieces.Who is this rogue demon who could spell the world's doom? Horror of horrors, it is AXEL.
