Best way to get risette on very easy/ng+?

[SuperTrunks979]

So I died to the first boss a few times and just decided to start on very easy. Now I'm about 30 hours in and wondering what the best way to do hardcore risette will be. Should I attempt to do it on very easy or my new game plus? I just did the video game style dungeon and am level 54, so I think I'm overlevelled. If I do new game plus, I have to try to stay underlevelled, but then I think I also need to get up to level 91 to make the final persona. What would be the best way to go about it?
