Killers

I'll leave this up to the writers, but generally they should be members of the enemy forces who've captured the two girls alive after an intense battle.

The ruins of a farming village.

Scenario

Interrogation of the two survivors, then execution.
Or just skip straight to the execution, whichever you feel like.
