@Wolfwhistler I hope so. I know it's super cheesy and kind of a cliche at this point, but I really enjoy the "and then a normal person accidentally became the demon king" plot.
The region they banished him to is considered cursed, as well. It's been awhile since I reread the beginning chapters of this, but that region of the ocean has a bad reputation as well, doesn't it? They've basically set him up to become the Demon King, reigning from his magical Super Atlantis in the middle of the Bermuda Triangle.
Hopefully it doesn't get dropped. I enjoy things like that. It's not terribly highbrow, sure, but then, neither is popcorn.
