This is what I think how the Battle between DxD against Rizevim and 666 will be:

Non-Sacred Gear Possessors vs. Rizevim and Sacred Gear Possessors (mainly Longinus Possessor (Ise, Vali, Sairaorg, Dulio, Cao Cao, and maybe Gasper) vs. 666

At least that what think how the final battle will be.

I will be looking forward to seeing how Ise grows.
