Ajuka created the Evil Pieces for the purpose of replenishing the Devil race's population. Whether it was purely to increase the Devils numbers, or to actually "repopulate", I don't know. Either way, I highly doubt Ajuka, being the thurough genius that he is, would "half-ass" the Evil Pieces reincarnation mechanism.

So I firmly believe that the Reincarnated Devils are, in fact, genuine Devils. Just in "different shapes."

Same thing for the Reincarnated Angels too, since the Brave Saints were based off of the Evil Pieces.

The only reason (I bet) that the Reincarnated Devils are treated as a "seperate", "impure" race is because of the arrogant, narrow-minded, self-rightious bigotry of the Noble Devils. The only difference between the "Pure" Devils and the Reincarnated ones, is that the "Pure" ones were born as Devils. The Reincarnated ones were "Reborn."
