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!
There's nothing but pain, even 
if I were to stay alive...
