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!
As of this night, the boy's fate 
begins to change greatly, but...
A partir de esta noche, el destino del chico 
empezará a cambiar drásticamente, pero...
A partir desse dia, a vida do
 garoto seguirá um novo rumo.
