I'm not completely sure what Phantom Brave on PlayStation 2 was supposed to be a successor to: Disgaea: Hour of Darkness, La Pucelle: Tactics or some other cult hit tactical role-playing game.
But it doesn't matter because Phantom Brave: We Meet Again is Wii a port of the PS2 game—and therefore not beholden to whatever inspired the original. The Wii version does have some new content, including a character detailed on the game's website named Carona who's actually the main character, Marona, but from another dimension.
I'm not quite sure I get it, but maybe you can from the screen shots. The game is due out this June.
