I hope this doesn't go with MC completely isekai'd. I like seeing him being able to come back and forth through his avatar. Also I hope that every choice he makes as a "god" matters and actually having impact when he decides to visit his world. It'll make a good interactivity between his two lives.
With that much demon you'd think the government would at least step up and try to do stuff? But all the things shown feels like even the society is still unaware of them existing.
