Since the tender age of nine, Hayate Ayasaki has busted his behind at various part-time jobs to support his degenerate gambler parents. And how do they repay their son's selfless generosity? By selling his organs to the yakuza to cover their debts! But fate throws Hayate a bone...sort of. Now the butler of a wealthy young lady, Hayate can finally pay back his debts, and it'll only take him 40 years to do it.

Whatever problems this manga runs up against, the solution is always the same: add more girls! Hayate's recent castle dungeon crawl (don't ask) has introduced him to Konoha, who has a thousand problems, but getting guys' attention ain't one. This spells trouble for all the girls with crushes on Hayate. But things aren't any easier for the girls without crushes on him, as Saki accidentally reveals her feelings for Wataru, and Chiharu accidentally reveals her double life as a maid. Plus, and the Movie Study Club deliberately exposes the world to the greatest cat video ever made.
