The training does not justify the growth of issei, do you think that sairaorg, saji, cao cao or vali have not trained? even three of them have been in the supernatural world longer than issei ... who 1 year ago was a normal person without any fighting skills and now fights with gods hand in hand, is that justification? Without the miracles of Issei, just now would be a high class demon.
