Meet Sabato Obiga, a hapless young teen trying to find himself in the world, which is made all but impossible by his frighteningly flamboyant family. Scaring away every girl he brings home, Sabato's family seems to revel in his misery - but could there be more to their torment than meets the eye?

Hayate's parents sell him as an organ donor to the yakuza - an idea Hayate isn't too crazy about, so he decides to kidnap someone and ransom them for 150 million yen. The girl he attempts to kidnap, though, misinterprets Hayate's intentions, and thinks that he is confessing his love for her. The girl, Negi Sanzenin, turns out to be the only daughter of a super wealthy family. Negi buys Hayate from the yakuza and to pay her back, Hayate agrees to be her butler.

Final exams are close at hand and Hayate can no longer afford to ignore his studies, but if he's hitting the books, who will keep the Sanzenin mansion spick and span? Anticipating just such an occasion, head butler Klaus arranges for Mecha Butler No. 13 to take Hayate's place. Is Hayate truly this easy to replace?

A meteor has fallen somewhere near the Izu Peninsula, an area well known for its relaxing hot spring resorts. The tourist trade is thrown into a tizzy when word leaks out that this meteor also seems to have imbued the local hot springs with cosmic powers, including (but not limited to) the ability to raise one's grades or increase one's bust size.

The Izu meteor may not have gifted Nagi with the pneumatic figure of her dreams, but it's left one surprise: a bug-eyed little alien girl looking for her lost spaceship. If Nagi helps she might score a biogenic reward, but will the grateful E.T. increase her bustline by 30 inches... or her distance from Hayate by 30 million miles?

What makes a maid? When the ghostly priest who haunts the Sanzenin mansion (what, you forgot about the ghostly priest?) reveals that he can't rest in peace before fulfilling his last earthly wish, the ever-accommodating Hayate promises to help. Unfortunately, that wish is to hit on a nubile maid!

Nagi has done the one thing no one ever expected from the pampered heiress: gotten a job! But her first-ever day of work leaves her too exhausted to enjoy Sakuya's birthday party, an Osaka-style comedy spectacular where the birthday girl's friends are forced to perform before a massive audience. After a comedy buildup spanning several chapters and this cover text, can Hayate make 'em laugh?

Hayate's new career as a live-in butler for the mega-moneyed Sanzenin family is in full swing, but this job requires more than just mental fortitude and brute strength: he needs to be entertaining too. Whether it's standing up to fire-spewing robots or protecting his mistress's millions from her tycoon grandfather, Hayate must remain calm, composed, and hilarious at all times.

As if dealing with his mistress Nagi's outlandish demands weren't taxing enough, poor (yet perennially) hardworking Hayate has to suffer the ignominy of being challenged to a duel by Nagi's fiance Wataru Tachibana. With his saber at the ready, Hayate is prepared to defend himself... but is there any logical reason why he's even fighting a duel in the first place? Shouldn't the simple act of keeping the Sanzenin household spic-and-span be enough?

For full-time butler-in-debt Hayate, attending high school - even one tailor-made for his working class values - remains just a dream inside a dream, and the ritzy Hakuou Gakuin seems galaxies beyond his reach, especially since it's packed with the wealthiest students in Japan! Despite that, and in order to be a first-class butler, Hayate remains resolute in his desire to get an education.

To truly be considered a butler of the highest caliber, Hayate needs more than just punctuality, an unwavering sense of loyalty and the ability to keep his mistress out of tight situations - he'll also need to develop the ultimate fighting technique! Despite his best efforts, though, our butler-in-debt seems incapable of keeping out of duels.

With a prize of 150 million yen on the line, the traditional sports event at Hakuou Gakuin - the paired freestyle marathon - finally begins. Honor, pride, and even the fate of Hayate's employment are on the line, but how can he hope to win when his mistress Nagi would sooner French-kiss a king cobra than participate in anything remotely close to exercise?!
