Poor Hayate Ayasaki is responsible for repaying his parents' 150 million yen debt. One Christmas, he meets a girl named Nagi, and after a series of misunderstandings, he somehow ends up working as her butler. Nagi covers for Hayate's debt, but has Hayate dug himself deeper into a different kind of hole? A hilarious tale of butlers, love and battles (?!). Has the impossible come to pass? Does Hayate have...a girlfriend? Or at least a girl who admits to kind of not hating him? And what's her deal, anyway? The time has come for Hayate and Athena to get honest with each other, preferably via epic flashback. Whatever is revealed, Hinagiku will be all ears...
