No_Existence
but before that i have a question, are you planing to make mc and the girls go to this worlds or mc will create a digital copy of this worlds and leave it like that, because it would be boring and pointless if he just create a digital copy, personally mc should traveled for real this worlds and once he is in those worlds the girls would became real and will be able to deal with the fact ''their reality is false'' easily since now they are in a real wold.
