It's Christmas Eve. Normally around this time, people prepare to celebrate this sacred holiday. However, there's one person in this world who won't have a Merry Christmas, and that person is an poor, unlucky boy named Hayate Ayasaki, when his aloof parents get a debt worth 156,804,000 yen (approximately 1.3 million US dollars) and sell Hayate to the Japanese mafia to pay it off!
But my very life's in danger because 
of those worthless parents of mine!
¡Pero mi vida está en peligro 
por culpa de mis inútiles padres!
Só que graças aos meus pais minha
 vida está correndo risco agora.
