Emilia, meanwhile, makes a trip back to Ente Isla; but when she doesn't return at the promised time, both demons and heavenly agents begin causing trouble in Japan. The devil may have to finally return to his own world to sort it all out, but what will this mean for his career in the fast food industry - and the precious friends he's made on Earth?
