Looks like Trinity Universe will have two storylines, one good and one evil. The evil one has a devil dog as the protagonist (Kanata) and will feature Etna from Disgaea, as well as other Nippon Ichi characters (Prinny and Flonne?). Supposedly, the combat system is similar to Xenogears (AP system and skills assigned to three different buttons and inputting set sequences will do more damage).
