Kouhei frowned slightly as he tried to process what Petra had just said, because the term "Holy Book" sounded important enough that he immediately assumed it had some enormous significance behind it. At the same time, he had no idea what she was referring to, and the more he thought about it, the more he suspected that it was probably something completely different from what the name initially suggested.
"Holy Book? What exactly is that?" Kouhei asked. "I am assuming you are not talking about the kind of book I'm thinking, considering the way you referred to it."
Petra gave him a small nod, almost as though she had expected him to make that exact assumption.
"If you were thinking that it was the Bible, then you are correct that it is not," Petra confirmed. "The Holy Book is something that dates back so far that the records contained within the Bible cannot really be compared to it. The difference between them is simply too large."
Kouhei raised an eyebrow as he listened.
