Maybe Issei becomes later the Head of ExE and maybe the Supernatrual Prime Minister and the Face of the Supernatrual. He would be perfect. He is loved by most Fraction and a Hero. He is one of the Kindest Devil/Dragon Hybrids that there is. I even think Issei would be a very good Angel. But i think Issei can turn in one of the best Leaders and even supras the older Ones.
