The holidays have come to Humming Dining! Halloween's up first -- the perfect holiday for a Demon Lord. But the Boss seems even more thrilled than Amon, and commands her staff to wear costumes -- the cute kind, of course! After that, it's the most wonderful time of the year...for home invasions! Highly suspicious of this Santa Claus, the "creep" who sneaks into people's houses, Amon decides to confront him on Christmas Eve -- and it's up to Kouichi to make sure St. Nick makes an appearance.
