IIRC you max her social link before beating the december dungeon. Then after you get the orb from Igor in the True Ending you return to the velvet room and talk to her.

In NG+.

can I use a save that's been NGed three times already, or do I need a completely new slot?

@Migrant does it even matter?

Just needs to be a NG+ file, doesn't matter how many times it's been NG+'d. Just can't be a pure new game.

alright, thanks. much appreciated!

Don't forget to equip me well, I don't want Margret to kill me.

you've died repeatedly during my four consecutive playthroughs, so I don't think that matters all that much...

The best way to beat P4 is to turn off the game console.

ayy lmao, no.
