Okay, so some people think that the LN battles will end in volume 21, remember volume 22 is the end of the strory, since the author said that volume 12 is half of the story, and I doubt that the 666 can be killed/sealed/beaten in one volume, I just hope the author doesn't Nerf the 666 powers and abilities, or it will be a complete waste for the number of monsters 666.

And I don't think Hades or Shiva are good people, so they might back stab the three factions, and I want to see sirzech in action against Shiva and hedes.
