to the first Anon, thank you. I think the Old Devils will draw the Gremory peerage into a rigged RG, plunging them into the RG World. As for the Four Horsemen, I believe that is up in the air. It could be the 666 creates them or it could be Marvel's Apocalypse's Four Horsemen where they were people who already existed who were transformed into the Four Horsemen.

to the second Anon. Ishibumi's never really inserted mythical beings that are outside the known mythologies, such as Hindu or Norse. It would be interesting to see Cthulhu and co, but unlikely. If Ishibumi was to do that, they'd probably be the gods from the other world, or perhaps Ishibumi will simply create new ones for the other world. I hate to play this card, but it really is up to the author, but I do agree with and join in your excitement.
