Shimohara, Georgette and Hikari are out on patrol when they find the whole lake near the base has frozen over!  It's an ice Neuroi!  They engage the enemy, but it's too cold, and freezes their units solid.  The Neuroi then proceeds to freeze the entire base!  With no one else able to launch, it's up to the three of them to take out this frozen foe.
but we believe once the lake starts 
to freeze, they'll swarm south.
لكن نعتقدُ أنّه حالما تبدأ البحيرة بالتجمُّد
سيزحفون نحو الجنوب
aber mit dem Gefrieren des Sees werden
sie ohne Verzug gen Süden aufbrechen.
Descenderán de golpe 
cuando se congele el lago.
Descenderán de golpe
cuando se congele el lago.
Quand le lac aura gelé,
ils se dirigeront vers le sud,
ma quando l'acqua comincerà
a gelare caleranno di colpo verso sud.
mas acreditamos que quando o lago 
começar a congelar, eles irão para o Sul.
