They Call It...
"Ailsa Tatsuya."
Eska blinked, not quite understanding.
"Her name is Ailsa Tatsuya, not Ailsa Cultus," Ryu said lightly.
Eska opened her mouth to say something, but took a pause instead. Now that she thought about it, Ryu did indeed have a Faerie Life Partner, he had entered the library with her once before. In fact, it was because of her that Ryu had become confident enough to enter the second floor at all. Before, he had stuck to the first, third and fourth floors, not wanting to take the risk of putting his life in their hands.
And, if Eska thought about it at a deeper layer, it was indeed quite rare for a normal individual to reach Ailsa's level of strength. It wouldn't be too surprising if she was, indeed, royalty. It seemed that she had accidentally said something she shouldn't have.
But, once again, Ryu continued to eat as though nothing had happened.
