An unambitious young man is forced to join a dark Christmas company that delivers bad gifts to bad children.

Miharu Hino, who has no redeeming qualities, fails his university entrance exams, and for three years without success in job hunting, he spends his days at a convenience store where he is forced to take responsibility for his co-workers' clumsiness. On the third Christmas night, Miharu, who has reached his limit, steals a cake to be discarded like his colleagues, but is scolded by a man in a black Santa suit. Miharu, who was told he was a "bad boy", was kidnapped and found himself at the Arctic Company, the home of Santa Claus. Miharu is perplexed by the strange environment in which there is only a black Santa even though it is Santa's home base, and it is a company. And Miharu remembers the important relationship between himself and Christmas.
