IMO, Reflect will be useless against Rizevim's SGC. My money's on a new Ability, perhaps the "answer" to Vali's quest to conquer the EJOD will be what wins him the fight. IMO, Issei should be the one to fight Rizevim. As of right now, he's only DxD that can actually deal Rizevim any damage. I know there's Michael, Sirzechs and Ajuka, but I highly doubt they'll join DxD at the front lines. Their leaders of their respective factions, so it would be bad for them to be lost. I guess my real question is what kind of ability do you think Vali will awaken?
