Hayate the Combat Butler

ハヤテのごとく！

Saddled with a 156-million-yen debt his runaway parents left behind, unlucky teenager Hayate Ayasaki tries to escape loan sharks and ends up rescuing Nagi Sanzenin, the young heiress of an enormous fortune. Mistaking his desperation for a love confession, Nagi takes him on as her personal butler. Hayate works off the debt at the Sanzenin mansion alongside the head maid Maria, fielding the eccentric demands of the otaku-obsessed Nagi and the dangers that follow a girl with that much money.
