I wonder what that Independent Demon Policy is. I guess in this timeline, Hades was demoted by Twilight rather than him leaving of his own free will then. Also Poseidon didn't call Twilight, Demon King but by his name when talking to him. I guess the poor demons Princess killed are really dead now. No Leo to bring them back this time. This Twilight appears to be more willing to get things done than the old one. I believe the old Twilight had a no hurting the hostage rule but I doubt there's such a rule here. The Hero's probably dead since he was pretty useless in the beginning.
Twilight looks so confused when Cursed Musician was talking about the old Demon Castle.
