"Because no children are born here?"
Da Vinci
"That is the conclusion I came to as well. But there's another issue. We've learned so far that fairies are mimicking human society. It would imply that both of them are the same way. What fairy society lacks, human society also lacks. Meaning... humans in the fairy realm cannot reproduce. The concept of giving birth is lost here. I became certain of this when they didn't use terms like 'parent' and 'child', but 'past generation' and 'current generation'."
Muramasa
"Hold up a minute. It makes sense for fairies to come about naturally. They're like nature's limbs in the first place. But how would humans come into existence? They can't exactly come about by themselves, can they?"
Da Vinci
"Humans are 'produced'. I do not know if it's something similar to artificial insemination, or a process like creating a homunculus. But they are created individually, without parents or siblings, carefully nurtured, and then shipped off. Of course, marriage customs like husband and wife exist, but they cannot produce offspring. That is what being human in this world is. From our point of view, it's rather inhuman. But for the fairies of this world, it's the way of life... Even Gareth and Artoria wouldn't question it."
