Also the Devil is most likely the Death devil, but Fami said it's a Primal Fear and I highly doubt Fujimotors would make Death devil a Horsemen of Apocalypse and a Primal Devil at the same time, so I think it's going to be a different devil.
Wait hold on, how did a primal fear end up on earth?
Aren't they supposed to be in hell since they've never died?
A contract with the Hell Devil perhaps?
It gets me anxious when they bring up the future devil in the conversation. His involvement in the past has already given us a good example.
Just worried that he says anything about Denji or Asa here...
