The Witches are preparing for a large-scale attack on the Neuroi nest, and to do that they'll need a new weapon.  This new weapon is being transported via a supposedly safe route. Krupinski is given the task of defending the convoy.  Some of the younger members are a little worried about the always-joking Krupinski, but when a powerful Neuroi attacks, she gets the opportunity to show them what she can do!
It's like one of Fusou's
Hamaya good luck charms!
!إنّه أشبه بإحدى حِليّ الحظّ السّعيد الخاصّة بفوسو
¡Como las flechas 
ceremoniales de Fusou!
¡Como las flechas
ceremoniales de Fusou!
C’est comme les flèches magiques

Come le frecce distruttrici del male di Fuso!
é como um Hamaya de Fusou!
