Adam = Denji
Eve = Asa
Everything will be "reset" at the end. No humans because Yoru's nuke would have wiped what's left of humanity away and no devils because Pochita will eat the Devil Devil, erasing even himself in the process. The earth will be almost barren besides Denji and Asa. Denji -- the second Adam like Christ -- and Asa will repopulate the earth through the power of sex.
