So, can someone explain the categories of this game?

Why is regular NG only on hard and there's no normal like in P3P? And why is there no "The Answer" category? (Since "The Answer" it's exclusive to this version)

Or is this like what happened with NG+ in the past that it wasn't added because there was no run of it? If that's the case, how can someone submit a run on a non-existent category?

You can read parts of this thread, particularly my first response: https://www.speedrun.com/p5/thread/ehx1w

It applies to this board as well. Having a bunch of empty categories cluttering the boards isn't very helpful. As far as The Answer goes. I simply removed it for now cause it was empty and didn't have any runs.
