"You're probably unaware of this, but the beast race is forbidden from marrying humans. Even if such a union were to occur, they would be unable to bear children. In Supreme Beast Citadel, many have formed emotional bonds with humans, but in the end, not a single couple succeeded in conceiving. That's why we've always believed that forming a bond with humans was a violation of the laws of nature. The fact that they can't conceive is the punishment. But after learning about you, I want to know how you were born and how your parents managed to avoid such punishment," Luna explained further.
Upon hearing this, Jacob was taken aback. He had never known about such a rule that forbade the beast race from marrying humans, and the fact that such unions could not bear children puzzled him greatly. Does that mean my union with Fiora is against the laws of nature too?
