I have a question about new game+ and the grade shop. Say I used up the grade points for my new game and the rest is saved over. When i beat the game again would I have to rebuy the old stuff from before to use in another new game or it stays plus the new stuff I brought?
You see, when you 'buy' things in the grade shop, you don't actually waste your grade. It'll keep on your other NG+s This means that, once you have enough grade to buy everything in there, you don't have to worry about it anymore.
