Hino Miharu, unable to get into a decent university or land a full-time job, lived a down-on-his-luck life working at a convenience store where both his coworkers and customers treated him like a doormat. That is, until Knecht, a mysterious faceless man dressed in a jet-black Santa suit, whisked him away to the North Pole for a job at his company, the Santa Claus House! With a hefty salary, incredible benefits, and a dorm filled with wonderful coworkers, Miharu works diligently, despite his bizarre manager and the strange nature of his duties. He soon finds out that luck may not be completely on his side when his least favorite person in the world suddenly appears, missing tooth and all.
