Not to mention that the first post mentions that the major players from the game franchises are, for the most part, nowhere to be found. Which I expect will be explained at some point. The Horseman, Dante, Bayonetta, and others are probably involved or tied up with something else for the time being. Or maybe they got captured by our main villains after being blind-sided or something. We just don't know yet.

We've already decided how they disappeared and their reasons, the Horsemen of course are behind the Seals and are only summoned when enough are broken as Lugubrious had said. Dante and Bayonetta though will make appearances midway through the story or towards the end.
