Nagi, Hayate, and Maria go to a Christmas party hosted by Nagi's grandfather. Just like the previous Christmas party, Nagi escapes - this time with Hayate. They head to the park where Nagi tries to make romantic advances on Hayate, but they are interrupted by a mysterious dark butler, Cyborg Butler, and Superintendent Kirika. Hayate is defeated, but they are saved by Himegami, who now calls himself Princess God. The next day, Hayate fails at all his butler chores and Himegami explains it is because Superintendent Kirika drained all his butler powers. In order to keep Nagi safe, Hayate resigns as Nagi's butler and leaves the mansion.
