Considering that they're the main antagonists of the TRPG, and we're seeing some of the TRPG in the anime (although in characters/Adventurers, not Genius), I think it would be a logical extension to say that they'll appear.

The monsters themselves are shrouded in mystery. It is certain, though, that they did not exist prior to the Apocalypse.
