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?!
It's a crime that only kids do it!
Wenn Kinder das dürfen,
dann wir auch!
¡Es un crimen que solo
los niños lo hagan!
¡Es un crimen que 
solo sea cosa de niños!
C’est du gâchis de ne laisser
que les enfants faire ça !
È un peccato che solo i bambini lo facciano!
É um crime só as crianças fazerem isso!
