I left that confidant for last even though Morgana kept nagging me to check her out.

I started a new game plus as well probably on normal though, but then I forced myself to stop after the Kamoshida since I don't really have a game plan other than maxing out the confidants I missed. And I really hate the mementos portion of the game, it's in start contrast with the rest of the title has to offer.

It took me 97 hours on normal and it felt really easy in the end since I maxed out most of the confidants that give you an edge in battle. The hardest boss for me was Futaba's mother. My only issue was that you cannot max out every confidant on your first run.
