Black Night Parade Vol. 1 (manga)

Hino Miharu will be spending this Christmas just like the last: alone and working a dead-end job. All he wants is good employment, but when he meets a Santa Claus dressed in clothes as black as coal, he has no idea he's encountered the real deal... sort of.

The Santa Claus dressed in red makes Christmas happen for good children everywhere, but his darker counterpart handles the holiday for the bad kids. As a name on the naughty list, Miharu is dashed away to work for the shadowy Santa. The pay and benefits are great, and his co-worker is cute - but will this end up being the dream job he's wished for, or a nightmare of a Christmas?!
