First of all the highschool dxd Ex is not CANNON..2nd issei already surpasses Vali.even if he is descendant of Lucifer..Issei is like a child of TWO STRONGEST BEING IN DXD(GREAT RED & OPHIS)

So if Issei and Vali will have a rematch..vali will lose instantly if Issei will use DxD Armor..(Infinite power LOL)
