* After spending eight years as the Wandering Protagonist, Asagi might finally get her game! This is all thanks to a promotion in which Creator/NipponIchi said they would make the game if Asagi's Fan Club reached 10,000 followers.
* Watching Adell and Rozalin's relationship develop over the course of their DLC cameos. Even long after the release of their game, Nippon Ichi has allowed their relationship to become stronger and stronger with each appearance they make. By the time of ''Disgaea D2'', not only has the "belligerent" part of their BelligerentSexualTension practically disappeared, but Adell has made it clear that [[spoiler:Rozalin's True Zenon form]] is not excluded from his affection.
