Trust me pal, Great Red and Ophis' powers arent necessary for Rias and Kiba. If he did unlock them they wouldnt even be able to lay a single scratch on Issei. Best save it for Indra because he's that strong. I hope that once Vali and Issei reach dragon god levels that people will realise they just cant compete with the Heavenly Dragons and find opponents who they can call their true rivals because those two are so out of reach. Only Crom Cruach can fight on par against them with the highest chance of winning and they will surpass him as well.
