In the manga and LN they make it clear that seeing the nun's (likely an Apostle) absence of humanity was an emotionally scarring event for Belta, as simply recalling the incident provoked an obvious traumatic flashback for her. She indicated to have either shouted or screamed in recounting it to Mieldi Reisen. That kind of reaction suggested someone who wrote the story either witnessed/ had such a traumatic episode that they could incorporate it into Belta's Personal History. You don't even need to have served the military in a crisis to have such a flashback. They're documented in anyone who suffers PTSD from any form of brushes with the evil in the world.
