Emilia:  "Oh, so they’re Kararagi words. You know, Subaru, you tend to be well-versed in the strangest trivia. So I guess it’s not all that strange that you would know these Kararagi words."

Subaru:  Subaru was grateful to have gained Emilia’s trust, but it irked him that a strange misunderstanding had gotten her there. Still, Subaru set this feeling aside and pondered the meager reactions around the table. The dead and living, bonds and souls—Subaru understood that they were inseparable from the concept of life and death. "Oh—is it because spirits exist here? Come to think of it, the lights of lesser spirits I see in the garden at night do seem to kinda fit the spooky vibe."

Emilia:  "Wait a minute—so you’re saying they’re the same as spirits? But spirits are their own thing…aren’t they?"

Roswaal:  "No, no, Lady Emilia, I believe what Subaru is talking about is something more along the lines of hollows."

Subaru:  At that moment, Subaru sensed the air freezing and crackling. Emilia froze with a smile on her face when Roswaal said the word. But she wasn’t the only one who froze. It was also Rem and Ram, of course, but Beatrice too, her apathetic frown stuck on her face. Subaru looked at the girls in shock before turning to Roswaal and asking. "Sooo…what are hollows?"

Roswaal:  "In short, a hollow is formed when a deceased person has regrets or a lingering attachment to the world of the living. Unable to return to Odo Ragna, they continue to roam our world… I suppose that’s the best explanation."

Subaru:  "Oh, yeah, that’s basically the same. Okay, so they’re just called hollows here."After hearing Roswaal’s explanation, Subaru sighed in satisfaction now that everything was clicking into place.
