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.

The gang's seaside sabbatical has turned into a series of struggles for shorefront supremacy. Is anyone surprised? Hayate incurs the wrath of ghost pirates, his brother faces a repowered Athena, Hinagiku is totally going to confess her feelings for real this time, and everyone else battles for the greatest prize of all: Häagen-Dazs. Oh, and they're still trying to run a waterfront cafe. There couldn't be a worse time for eternal side character Fumi to jump into the fray with terrible advice and a misguided crush.
