Dude the Final Battle will not come soon :D Issei will have enough time to train and perfect everything and learn new. Issei has the Body,Blood and DNA of Great Red in him so he should also have some of not most of Great Red Powers. Maybe GR have not return Issei to the Living just because he was nice but GR sees something in Issei. Maybe that Issei is the Hope for Peace or the Supernatrual World. But I don`t think Great Red just return Issei because he wanted just like he havent stole Ophis Place but guard it. Yeah Vali can do the same thing but Issei`s growth is much more amazing!

Issei is the only Dragon between Him and Vali, right?. Vali is only called a Dragon because of this Sared Gear Issei is a Real (little True Dragon). I hope with Dragon Deification Issei will be more Prideful just like a Dragon!
