It has been three months since Hayate was abandoned by his parents and started work at the Sanzenin Manor as a butler to pay off his parents debt. However, being the butler for the otaku-crazed lady of the house, Nagi Sanzenin, is a hard task, not made easier by the friends and enemies of the Sanzenin, of which Hayate always ends up in the middle of the problem.
