Sakura
Sakura frowned at the girl's words. She didn't possess any manatite ore, or anything else that she suspected that this "Eruraviel" might want, and the thought of what "alternate methods" of payment might mean to someone with no apparent concept of her personal boundaries sent shivers down her spine.
"No, sorry, I don't have any of that", she replied.
Still, despite her reservations, Arcaena didn't seem like she had any ill-intentions, so Sakura saw no reason not to follow after her, relaxing into the seat as she considered whether there was anything she could offer.
"A cup of tea would be lovely, thank you", she said. "I'll try to think of something I can offer whilst you're back."
As she waited for the girl to return, Sakura thought hard about what rare or unusual things she might be able to offer until, finally, she came to a realisation. There was only one thing that she or her husband could do that was truly unique, and that was Shirou's ability to trace swords. She wasn't totally sure whether it would be enough, especially since his swords tended not to last very long, but it was at least something she might be able to offer. Continuing to ponder whether or not it would be enough and how to raise the idea, Sakura waited for Arceana to return.
