I forgot to mention its interesting at the end of P5 how Morgana retains his form as a cat despite the metaverse disappearing, black cats go back to Faust as it was one of the forms Mephistopheles disguised himself as. Along with the final persona being a demon lord Satanael and the overarching theme of Rebellion against the existing order of reality it seems there is a very strong Luciferian/Gnostic theme in P5.
