The OP for P3P was posted not too long ago. I think it differs from the style of P3, P3:Fes, and P4 quite a bit, both in musical choice and visuals. A lot of people seem to hate it, but I think it’s growing on me.

The OP keeps on mentioning a butterfly effect. That, with some of the delayed mirrored images, may suggest some subtle changes in the female version of the story? Maybe, some of the big events are slightly altered due to the protagonists actions in the male story? Who knows.
