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.

Sí. Combatir Neuroi con Neuroi.

Acho que eles acham que precisamos 
de um Neuroi para ganhar de um Neuroi.
