It's New Year's Eve, and the Defense Club members are gathered at the Kurotama Bath, fighting over the TV and cozying up at the kotatsu with their usual leisurely air. Although they expected to go their separate ways after eating Gora's home-made soba, the area directly around the Kurotama Bath is suddenly hit by a blizzard, which cuts them off from the outside world! How will the club react to this disaster situation?!
That's the Gora-san sweater 
we stayed up all night
¡Es el que pasamos toda la noche
¡Es el que pasamos toda la noche
C’est celui qu’on avait passé
la nuit à tricoter pour Gôra !
È quello che abbiamo fatto per Gora-san,
lavorando a maglia per tutta la notte!
Aquele é o casaco do Gora-san 
 que passamos a noite toda
