You won't be able to do everything in a single run (some character profiles will be left incomplete as a result), but beyond a bonus option during an event during the final chapter, one which doesn't award its own trophy, there's no story content unique to NG+. No true ending, but the character-specific dialogue that you get during it is dependent upon that same event during the final chapter (with whom you get to choose for it tied to link levels and various bonding events).Ok I have been playing this game for a week now and I'm at chapter 5, just after finishing 5th floor of old school house. Hopefully I can finish it this week.
What I want to know is if NG+ add more story or require for true ending (if it got one)?
EDIT: Ah, there was also apparently one NG+ adjustment to an event in the final chapter if you bring Emma, but other than that, nothing major.
