Jayose has a "copy" spell for books! Raikana uses something similar!
Oh really? Which Way is that under?

It's not specified in the quest that mentions it, IIRC, although I would guess it's either Blue (since ink is liquid) or Azure (since books are a visual medium, and manipulating appearances is one of Azure's specialties). Yliakum also enjoys a technological level where a printing press would be completely within their technological reach, judging from things like the Winch, although I doubt anyone would bother to invent one when magic can do the job just fine.
Personally I think it's reasonable for Raikana to charge 1 circle for the paper. Yeah, it's not totally in line with the settings' guideline about pricing, but the player economy is always going to be a little inflated because there aren't that many producers, and there aren't that many efficient ways for PC merchants to compete directly with each other, so...
