I dont say he will, but i belive he will become a Dragon God Class or Dragon God Emperor or Ture Crimson Dragon God Emperor, he will be higher than God Class but what I don`t know, hell even Loki and this thing was shit scared of Issei. And come so impssobile is it not for him to become something LIKE Dragon God Class.

Issei = True Dragon Emperor

Vali = True Lucifer
