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 manga-drawing duel is upon us! The combatants: self-made woman Ruka and lazy wastrel Nagi, who continues to insist she's the heroine of this story. The prize: Hayate's hand in marriage! After procrastinating for volume after volume, Nagi has mere hours to write, draw, and publish an entire manga. Meanwhile, Ruka is forced to choose once and for all between her music and her art, and the decision is tougher than she expected. It's up to Hayate to save the day--but whose day will he save?
