Game developer Nippon Ichi Software revealed the title of the newest Disgaea game, Disgaea D2 for the PlayStation 3 console, at the Dengeki 20th Anniversary festival on Saturday. Disgaea producer Shōgo Kosakai, Tomoe Hanba (voice of Etna), and Yuko Sasamoto (voice of Flonne) attended the event.
This new game celebrating the Disgaea series' 10th anniversary will feature Laharl as the main character, with Etna and Flonne at his side. Kosakai explained that because it was the 10th anniversary, the staff decided to return to the roots of the game and bring back Laharl as the main character, instead of introducing a new protagonist for a completely new Disgaea 5. The game, previously codenamed as "Project D," tells the continuation of Laharl's story after the events of the first game.
I'll just leave this as a wiki for more as it develops, because I'm sure you are all as excited as I am (or maybe not, lol!)
