Christmas is a magical time that makes people go a little crazy. On the day of Christmas Eve, Yufuin makes the shockingly uncharacteristic suggestion that that they hold a Christmas party. Gora joins the Christmas party at Kurotama Bath, and even more unexpected visitors show up, throwing the party into chaos! A one-night-only miracle of love and confusion begins!
I come on behalf of all those 
forced to work without rest...
Der schwarze Repräsentant
aller Arbeitstiere zu Weihnachten …
¡Soy el oscuro representante
de los que solo trabajan!
¡Soy el oscuro representante
de los que solo trabajan!
Je représente
ceux qui n’ont pas de repos,
Sono l'oscuro rappresentante
di chi è costretto a lavorare senza sosta...
O representante desse trabalho 
 forçado sem descanso...
