Here's my thought on that.

Ajuka made the Evil Pieces unable to reincarnate Gods & Goddesses on purpose.

Think about it.


 * If the Devils were able to turn Gods into Devils, would the other Factions be ok with that? * Would this not make the Devils an even bigger target than they were when the Original Satans died (before the new ones were appointed)?


 * The Three Factions (Angels, Fallen Angels & Devils) desperately wanted to keep the "peace" and not get other Factions involved. Ajuka knew this, and he likely knew that if the EP's actually could reincarnate Gods, the Devils probably wouldn't be able to resist trying it (they do value strength when choosing servants).

But there is one thing. It was implied (if not stated) that Gods can't be reincarnated "because they're too powerful for the EP's to work, even if they used a Mutation Piece."

I think that was just the explanation (excuse) that Ajuka gave for why the EP's wouldn't work on Gods. Because if that was really the case, then Issei's EP's wouldn't have be working because he has achieved Heavenly Dragon-Class (which rivals/equals God-Class), Rias wouldn't be able to reincarnate Rossweisse, who is a Valkyrie (a "sub/half-God"), nor would Sona be able to reincarnate Bennia, who is a Grim Reaper (a "sub-species" of Gods). Although in Bennia's case, she is half-human.

I think that the Evil Pieces only don't work on the "Gods," as in the ones who hold the "position of Gods."

Take two "Divine Spirits." They are both from the same Religion/Mythology, but one is a (or the) God, while the other isn't an major figure. Which one do you think the EP's will work on?... I think it will work on the "unimportant" Divine Spirit.
