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?!
Speaking of which, didn't we have plans 
to go skiing during winter break?
Da fällt mir ein, dass wir
während der Winterferien …
Por cierto, ¿no planeábamos ir a esquiar
en las vacaciones de invierno?
Por cierto, ¿no dijimos de ir a esquiar
en las vacaciones de invierno?

A proposito, non dovevamo andare anche noi
a sciare durante le vacanze di Natale?
Falando nisso, a gente não tinha planejado 
 esquiar nas férias de inverno?
