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.
No, my sister only survived 
because you were there.
لا، نجَتْ أختي فقط بفضل وجودك إلى جانبها
Was? Ach, wärst du nicht gewesen, hätte mein
Schwesterherz ihr Leben ganz abschreiben können.
¿Qué? Fue gracias a ti que 
mi hermana conservó su vida.
¿Qué? Mi hermana
sigue viva gracias a ti.
Mais non, si tu n’avais pas été là,
ma sœur ne serait plus en vie.
Não, minha irmã só 
sobreviveu graças a você.
