The twin rail guns have been destroyed and the Neuroi nest continues its advance towards Petersburg.  With Takami having exhausted her power, there's only one shot left: for Hikaru and Kanno to take the AP shell directly into the core itself.
The impact did this to it, but there's 
still magical power inside.
الإصابة فعلَتْ بها هذا
لكن ما زال بداخلها قوّة سحريّة
Elle est dans un sale état
à cause de la chute,
O impacto fez isso, 
mas ainda há poder mágico aqui.
