[C-K'R[PhoEniX]]

I am playing the game right now and I think there is an explanation. When you find the journal (dedocahedron) of one of your previous incarnations, it mentions that this psychotic incarnation somehow found out that after he died a couple more times, he would stop losing memories, but he also pointed out that he didn't want to die because he would no longer be himself then. That may be it, although I can't remember if the reasons why the NO would stop losing memories were also mentioned.
