I almost never bother with renaming characters anymore and even in games where I have to, I'll stick to an official name if there is one, or fall back on a name I always use (Tilos for boys, Alma for girls) unless we're talking old school trout at which point I go with a theme name for the whole team.

I'm just happy they gave the students names and I liked the playing card angle. Much better than Before Crisis where all of them were known simply by their weapon, well except Cissinei since she did eventually get an official name.
