When I first started a new game, I found and pressed all five switches in Holt. Nothing happened, and as I have not played Disgaea 2 before (but Disgaea 1 PC), I thought maybe I have to find something more. I proceeded in the main story, eventually startet a NG+ and just recently learned, that pressing the switches should have summoned "Friday MKII". Which it didn't. So now I have a savegame in Cycle #3 with no chance to get into the Dark World. There is no Friday MKII and I can't press the switches again, either. Seems buggy to me.
