Good luck on doing the Prologue boss and not throwing your PSP/VITA halfway across the room. He's already irritating on normal.
BTW, did you decide you wanted to accompany Estelle in ch1? I went Schera myself since she practically disappears for like half of FC until just before the final dungeon, so she didn't get a whole lot of playtime. Though if your playing hard mode Agate is probably the better choice since Schera is mostly average outside speed and arts.
