You guys are all misunderstanding something here. the nature of ones existence isn't the flesh but the soul. when issei was reborn, his soul was placed into draigs armor, then moved to his remade body and wasn't altered in anyway. GR's power allowed him to be stable enough to exist without his pieces but throughout that whole experience issei's soul remained as that of a devil reincarnated from a human. when you become a reincarnated devil, you inherit all of the attributes of what you were prior, so issei is a reincarnated devil with the body of a humanoid dragon. Saying he was able to resist the milk because he's part deity is inaccurate as while he in herited traits from GR and ophis, he is still a devil. it's the same reason why he's more vunerable to dragon slayers; the pieces inherit all the traits of the previous species.

Also, these unconfirmed spoilers about ophis wanting to make issei the third dragon god is heresay until proven otherwise, because according to that same rumor she has similiar plans for vali as well despite him not having either GR or Ophis in his body. ophis's power manifesting in issei's body and all things regarding exe or axa all refer to him unlocking ophis and great red's power. there is nothing to support the claim that he need's divinity to gain said powers, as it's already been said that he can use unnerfed dxd g simply by getting ophis and lilith to resonate along with proper training, as opposed to him becoming a god like vali speculated previously.
